The Sunshine Science Corner: Osceola Elementary School

Osceola Elementary School

Another wonderful trip to St. Johns County and a visit to Osceola Elementary in St. Augustine. I spent the morning working with grade levels during their planning time and the afternoon with the full faculty. An amazing school that is receptive to making the commitment to more science in the curriculum. Thanks for a great day. Thanks to fifth grade teacher, Mitch Gurick for the invitation and principal, Nancy Little for making me feel a part of her wonderful staff.

Kid's Corner

Let's start the new school year looking at the weather. In Florida we begin our school year with storms and very rarely with a hurricane. In every area of the country you can find weather that will have an impact on your life, so let's start off this new school year exploring weather!
Did you know that lightning during thunderstorms can cause compass needles on ships to move?
Benjamin Franklin's experiments proved that lightning was electrical and led to his invention of the lightning rod.
What observations can you make that tell you there will be a thunderstorm?
People learn what weather to expect by keeping records of what happened the year(s) before.
So begin the school year by keeping a daily weather record in your science journal - the temperature when you arrive at school amd the amount of daily precipitation.
You can learn about weather map symbols by going to www.hpc.ncep.noaa.gov/html/stationplot.shtml
You can meet meteorologist, Tammy Souza by visiting www.wtsp.com/company/bios/member.aaspx?storyid+92970

NSTA Science Safety Guidelines in the Classroom

Safety in the science classroom/laboratory requires thorough planning, careful management, and constant monitoring of student activities. Teachers must maintain a safe science program by exercising good judgment, providing proper instruction and supervision, and maintaining a written record of safety instruction. Teachers should be knowledgeable about the properties, possible hazards, and proper use and disposal of all materials used in the classroom. Students are expected to follow all safety procedures and rules in the safety agreement that they sign as well as additional instructions their teachers give them concerning the laboratory activities they perform.

Batteries
· Dispose of batteries that are leaking or corroded.
· Use regular dry cell batteries when teaching concepts
about electrical circuits. Avoid alkaline batteries which
can quickly generate enough heat to cause burns.

Candles (Grades 3-12)
Candles are to be used as instructional tools only!
Candles should be placed on a stable, non-flammable surface, such as a metal jar lid, a metal tray, or a pan of sand.
Students should be cautioned to avoid contact with hot wax.
Students should pin long hair back and avoid wearing loose clothing.
A fire blanket or fire extinguisher should be available.
Elementary students should have adult supervision at all times when working with open flames. (Assign one adult volunteer per group!)
Make sure that flames are extinguished before leaving a lab station. Never leave a burning flame!

Dissection
Dissection of animal specimens is not recommended for elementary students.
Plants are appropriate dissection materials for elementary students.
Preserved specimens should be purchased from a biological supply house.
Rinse specimens before distributing them to the students.
Dissections should be done only in well-ventilated rooms.
Gloves, goggles, and aprons should be worn at all times.
All equipment and lab surfaces must be disinfected, and students should be cautioned against touching their faces with contaminated gloves.
Instruct students in the safe use of dissecting tools before the dissection begins.
Dissecting scissors are the recommended tool for middle school; scalpels and razor blades should not be used.
Dissecting scissors and scalpels are the recommended tools for high school students. Scalpels should be used for incision only.
The most dangerous dissecting tools are those which are dull and therefore require the most force. Only sharp cutting tools should be used.
Special care should be taken to prevent bacterial contamination from unpreserved specimens. Unpreserved specimens should be refrigerated and used within 24 hours.
Remains of specimens should be wrapped in paper or placed in plastic bags and discarded in garbage containers.
Students should wash their hands thoroughly with soap and water, especially under the fingernails, at the end of the laboratory period.
During dissection activities, rinse dissection equipment in a disinfectant at least once a day.
Secure dissecting tools in a locked cabinet when not in use.

NSTA Position Statement - Responsible Use of Live Animals and Dissection in the Science Classroom

Dry Ice
Proper insulating gloves, eye protection, and protective clothing must be worn when handling dry ice.
Always handle dry ice with gloves or tongs – never with bare hands. Dry ice can cause burns.
Do not allow carbon dioxide gas given off by dry ice to accumulate in low areas. The gas is denser than air, and when it accumulates, can cause asphyxiation.
Never place dry ice in a sealed container since the resulting increase in gas pressure may cause an explosion.

Gas Burners (Grades 6-12)
It is important that students be instructed on how to use gas burners. The location and function of the gas supply inlet, air adjustment vent/valve, and gas adjustment valve should be clearly communicated.
Rubber tubing should be inspected periodically for cracks and hardening.

Glassware
Glassware should never be used for any purpose other than that for which it is specifically designed.
Due to the varying qualities of laboratory glassware, care should be taken in selecting glassware appropriate for laboratory experiments.
Glassware that is to be heated should be made of borosilicate (e.g., Pyrex®).
Do not use glassware designed for science experiments as a container for consumable liquids.
Always inspect glassware for chips or cracks before and after use. Cracks will eventually work their way through the glass.
When heated over a flame, a glass apparatus should be placed on wire gauze.
A Pyrex or Kimax glass test tube can be heated directly as long it is heated at approximately a 45-degree angle with its mouth pointed away from people.
Never heat a closed system, such as a flask or a test tube with a stopper.
Students should be reminded that glass retains heat. Any glass that has been heated should never be placed in direct contact with a tabletop, but rather on a ceramic wire gauze screen.
Students must never eat or drink from laboratory glassware.
Graduated cylinders should have plastic bumpers near the top lip. The bumpers are not to be used as quantity indicators but are to prevent breakage if the cylinder is accidentally knocked over.
Never place heated glass items in water.

Hot Plates (Grades K-12; only elementary teachers may operate a hot plate – not elementary students)
Hot plates are to be used as instructional tools only – not for personal use.
Only hot plates designed for laboratory applications should be purchased for student use. The heating element should be fully enclosed.
There should be an indicator light showing when a hot plate is on. (Do not bring a hot plate from home!)
Hot plates should be plugged into GFI-protected circuits.
Be careful to keep the cord away from water sources or the hot surface.
Students should pin long hair back and avoid wearing loose clothing.
Check for properly working thermostats to prevent dangerous overheating.
Use only heat-resistant gloves and/or tongs when placing samples on or removing samples from a heating apparatus.
Once the laboratory activity is completed, allow sufficient time for the hot plate to cool; warn students to be wary of the residual heat.
When the hot place has cooled, clean the surface with steel wool or a damp cloth, making sure that the power source is disconnected.

Human Tissues
· Laboratory activities involving human blood, fluids, or
tissues are not acceptable!

Incubators
Care must be taken to avoid breaking the thermometer when placing containers in the incubator.
The incubator must have a UL-approved, grounded plug. A GFI-protected circuit should be used.
Students should be cautioned never to touch the heating element.
Note: See the Animal Safety document for information on hatching eggs.

Iron Filings
· Purchase iron filings from an approved supplier.
· Keep iron filings away from fans or windy areas in the
classroom.
· Insist that students wear goggles when handling iron
filings.
· Caution students not to inhale or ingest iron filings.

Light/Lenses/Mirrors
Lenses and mirrors must be inspected for chips and cracks.
Lasers used in the classroom must be of low power (Class II or IIIa). Prolonged exposure to reflections from doorknobs, glass plates, diamonds, or other polished surfaces can cause retinal damage.
When UV light is used, appropriate UV protective safety goggles must be worn if there is any possibility of direct exposure to the ultraviolet rays.
Strobe lights can trigger seizures in susceptible people. Caution students not to look directly at the strobe light.
Young students should use polished metal or plastic mirrors instead of glass.
· Students should never look directly at the sun.
Microscopes and Telescopes
A microscope’s mirror should never be aimed directly at the sun. If an electric illuminator is used, it should be grounded or UL-approved and plugged into a GFI-protected circuit.
Telescopes without proper filters should not be used to examine bright objects such as the sun.
Lenses must be regularly disinfected with an alcohol-based lens cleaner.

Microwaves and Refrigerators
Foods for human consumption should never be kept in a laboratory refrigerator.
Microwaves and refrigerators must be plugged directly into wall outlets – not into extension cords.
Electrical devices used in the laboratory must have a three-prong (grounded) plug.

Mold
Observe mold only in closed containers. Many varieties produce spores that cause allergic reactions or are pathogenic to susceptible individuals.

Plants
Before using an outdoor learning area, examine the site for the presence of poisonous plants.
· Students with known allergies to pollen or spores should
not be required to participate in plant-related activities.
· Students should not bring in plant specimens from
ponds, ditches, canals, and other unknown sources.
· Caution students not to put any plants or plant parts in
their mouths.
· Alert students about toxic plants in the local
environment, including plants, such as lantana, which
may be found in school butterfly gardens. Ingestion of
lantana berries can be fatal.
· Students should wash their hands after handling soil
samples and/or plants.

Rocketry
· Use only factory-prepared, solid propellant engines
when launching model rockets.
· Students should wear eye protection when launching
model rockets.
· Never launch model rockets in high winds, near
buildings, tall trees or power lines, around low-flying
aircraft, or under any conditions that would endanger
people or property.
· The launch area should be cleared and free of flammable
materials.
· Check with the local fire department to be sure that the
launch will not create a fire hazard.
· Note: The use of air or water rockets also requires care
to assure that people and property are protected from
dangers inherent to projectiles.

Thermometers
Mercury thermometers are not permitted. Use thermometers that contain alcohol.
Anti-roll devices should be placed on thermometers so that they do not roll off a counter.
Use a rubber safety grip when inserting a thermometer into a stopper and lubricate the end of the thermometer before insertion. The teacher, not the student, should remove a thermometer stuck in a stopper. This can be done by slitting the stopper or inserting a cork borer.Do not use a thermometer in boiling water unless it is designated for that use.

A Few Science Centers To Try In Your Classrooms

Life Science Habitat:
a terrarium with some type of animal living in an enclosed appropriate habitat (possible animals include: crickets, frogs, lizard, earthworms, crayfish, toad, hermit crabs, land snails). Include magnifiers for viewing, resource books, paper and pencils for illustrations, rulers, scales, observation logs on a clipboard.

Take Apart Center:
discarded appliances, telephones, tape recorders, motors, etc. (all electrical cords have been removed) can be taken apart by young children to learn more about how things work. Tools for taking things apart include screw drivers, pliers, wire cutters, Allen wrenches, and socket wrenches. Never take apart computers, televisions, or microwave stoves – they have capacitors capable of producing electrical shock, even without a plug. Include books about how things work and a large tub for placing the parts of the object that have been taken apart (much of this can be saved for sorting activities, or art and science projects.

Structures Center:
An area where students use materials familiar to them (but not as construction materials) to create free standing structures. Materials may include garbazo beans and toothpicks, marshmellows and coffee stirrers; assorted building blocks; drinking straws and paper clips; or found materials.

Collections Center:
Groups of tubs filled with materials which can be used for students to create their own collections and reference books which will enable them to label all of the collection. Tubs might house shells, bones or skeletons, stamps, rocks, or found dead insects. Include in the center clean, Styrofoam meat trays, glue, file cards, and clear plastic wrap.

Reference Center:
A science library housing science reference book, how-to manuals, science related magazines, books about inventions and inventors, posters or pages cut out from magazines and laminated - all sorted by topic. Reference materials should reflect all reading levels.

Microworld:
An assortment of magnifiers and microscopes will be used to gain a different perspective of materials as they are magnified. Materials to be magnified might include using prepared slides, motherboards from computers, fur, fabric, feathers, populations of mealworms (eggs and young larvae can’t be seen without magnification), and pond water. Include plastic petri dishes, clear slides, file cards, tweezers and eyedroppers.

Motion:
This center explores how things move using a toy marble maze. The center is updated by changing out the commercial maze with paper towel tubes, blocks and marbles; aluminum foil and marbles, Hot Wheels track and cars; or ramps and cylindrical objects.

Science Toys:
Commercially available science toys such as “drinking birds”, balancing birds”, large gyroscopes, and other science toys are rotated in and out of this center with this question posted: “How Does this work?”. Possible answers are written on file cards and are posted by the toy. Students may add their own solution, add a comment or suggestion to another, or suggest ways that the answer may be found. Students are encouraged to look for the solutions on the internet and report the results of their search.

Data Driven:
Set up an independent AIMS/GEMS activity (usually either related to the topic being taught in class or covering a specific science big idea) complete with materials, worksheets, and reference materials. Each activity must focus on gathering data, graphing and interpreting the results.

Problem Solving Center:
Create a challenge that students must respond to using the materials that you provide. Examples include creating a 30 second timer using salt, plastic cups, paper cones and a stopwatch; creating a new and improved drink using only ingredients provided (seltzer water, fruit juice, 7-Up, etc.), an eye dropper and a 5 oz cup. Recipes are left on file cards; building a tower using only playing cards; etc.

Long Term Observations:
An area where experiments are monitored for long periods of time using science journals to input daily or weekly observations; to create ongoing measurements opportunities: to input results onto graphs or charts and analyze results; or to create time lines of events. This does not have to be an area inside the class. Examples include growing plants, mounds of dirt established to observe the long term effects of erosion, growing crystals, visiting a tree and observing changes, or population studies at a specific area of the school.

Science Jobs:
Can be a section of your library where books about scientists, inventors, or collections of magazine articles about science jobs may be found.

Science Museum:
An area where rock collections, insect specimen cases, animal skulls, fossils, models, or other unique things which might pique science curiosity are found. Boxes with collections of feathers, bones, rocks, unique artifacts ( a few of my artifacts include a complete skin of an armadillo, a grizzly bear skull, a small collection of eggs, the jaw of a shark, a Mastadon tooth, models of early airplanes, and a star compass used on early ships). This area is treated like a museum and is for looking, not touching. Also include books topic-related to the artifacts you provide.

Rules Kids Won't Learn in School

These rules were shared by Bill Gates at a graduation commencement.
1. Life is not fair. Get used to it.
2. The real world won't care as much about your self esteem as your school does. It'll expect you to accomplish something before you feel good about yourself. This may come as a shock.
3. Sorry, you won't make $40,000 a year right out of high school.
4. If you think your teacher is tough, wait until you get a boss.
5. Flipping burgers is not beneath your dignity.
6. It is not your parents' fault. If you screw up, YOU are responsible.
7. Before you were born your parents weren't as boring as they are now. They got that way paying your bills, cleaning up your room, and listening to you tell them how idealistic you are.
8. Life is not divided into semesters. You won't get summers off.
9. Smoking does not make you look cool. It makes you look like a moron.
10. You are not immortal.
11. Your school may be outcome-based. Life isn't.
12. Enjoy this while you can.

Why We Teach in Florida!

Fall and Winter Gardening In Florida
(reprinted from an article I wrote for KidsGardening last year)
As many look to the fall and winter seasons as a time of winding down classroom gardening, there are places where you will find a second gardening season filled with flowers, butterflies and vegetables. Gardening in Florida provides just such an opportunity. As you travel south until fall leaves cease to exist you will find a region of year round gardening that many would envy. As a science lab teacher and native Floridian my students and I do not experience the beauty of fall leaves or the excitement of the first snow, but our garden is filled with the color of flowers in December , our garden still hosts caterpillars and butterflies in January and we harvest cucumbers and tomatoes almost year round. Raised beds provide the year round home for dill, mint, pentas, salvia, milkweed, fennel and much more.
For years my elementary school garden has enjoyed the advantages and challenges unique to year round gardening. In the sub tropic zone of Central and South Florida the cool mornings of fall aren’t usually felt until mid November; a winter freeze threat usually exists for only a few weeks in January and February; our spring planting begins in early March; and summer comes to us in May. With the opportunity of an extended growing season come challenges. Garden pests are a year round concern; the depletion of soil nutrients is an ongoing battle; and garden management and maintenance become critical gardening skills.
Because the challenge of year round gardening can be overwhelming, in our school garden we have approached everything in manageable stages. Our research and past experiences helped us to realize that the soil in Florida is mostly composed of sand and organic matter and our rain pattern is seasonally inconsistent. As a result we undertook creating a diverse raised bed garden supported by in-ground sites where appropriate. The decision to rely on raised beds was made due to a number of factors. 1. We could more easily enrich the soil and control moisture, 2. We provide better control of nematodes and other garden pests, 3. All students would have equal access to the garden – from kindergartners to fifth graders to our physically challenged students, 4. We could better control weeds. Most of our beds are large, measuring eight feet square, others much smaller. Container gardens also are found throughout our garden and allow us to provide a greater diversity of plants.
Large beds were developed to provide the following experiences: one bed is filled with assorted mints, lavender, and other scented plants for a sensory experience; one bed contains only annuals so that students may better understand plant life cycles; two beds provide host plants for both caterpillars and butterflies (we have focused on Monarchs, Queens, Viceroys, assorted Swallowtails, Gulf Fritillary and Sulfurs); a bed of perennials is provided to measure plant growth; a bed of ginger and cannas allows us to explore bulbs; a bed dedicated to Southern wildflowers allows students to better understand that one region’s weed in another region’s wildflower ; a bed of vegetables that are constantly harvested; and assorted container groupings of kalanchoe, sunflowers, roses, ornamental trees and other plants.
Soil is revitalized courtesy of our rabbitry which provides the foundation for our large composter. Additional soil is obtained from composted matter available at our county landfill. Irrigation as needed is supplied through web-like hose of connected sprinklers we have created linking each bed to our main water supply. Our goal was to use as little water as possible. Seeds from the garden are collected, dried and added back to the beds as part of our understanding of the life cycle. The garden is maintained by our afterschool gardening club, as well as volunteer classes. Pruning and weeding are ongoing and vital to our gardens. With a mild year round climate many plants will grow at accelerated rates. Without a period of dormancy many plants have been planted in small areas only to eventually take over the entire garden space. Our own experience started one year with a Mexican Petunia staging a revolt and attempting to take over our entire garden through a network of vine-like roots. Unable to learn our lesson, we repeated the cycle with a determined ornamental potato vine.
Water gardening is popular in our state, but has its own challenges. Evaporation leads the list. If fish are part of the water gardening experience then tap water must be ruled out as the water source. Many gardeners have rain barrels or filtration systems designed to provide a constant source of appropriate water. Too much or too little water depletes necessary nutrients creating more work, and our wonderful sun also contributes to high growth of algae! And don’t forget that you may also find the occasional egret or crane looking for his next meal in your water garden!
Regardless of how you approach gardening in Florida the joys far exceed any challenges one might encounter. Our school garden has become such an integral part of our community that last spring it was the site of evening Garden Party attended by over 400 students and their families. Though we might out on miss the colors of fall leaves and the clean fields associated with the first snow, we in the Sunshine State celebrate with an explosion of colors everyday and invite you to come down and share in the warmth and excitement of year round gardening!
