Curated OER
Presentations
Students give presentations. In this unit culmination lesson, students present their bridge projects to parents. Students test their bridges and are evaluated using a rubric.
Curated OER
Catapults
Students are introduced to the concept of a catapult and how it is used with the help of a media presentation. They use catapults in a large, open area and record the distances objects travel. Students use the scientific method while...
Curated OER
Growing Barley and Detecting the Presence of Amino Acids
Pupils produce the greatest mass of plant material possible for 100 seeds of barley, and detect amino acids in barley plant material. They develop rules for the investigation, conduct the experiment, and prepare a computer spreadsheet...
Curated OER
Building-Stone Geology
Students examine building stones in downtown St. Petersburg in order t study igneous and metamorphic rocks in central Florida ( a huge area consisting solely of sedimentary rock). Each student picks a particular rock type used in a...
Curated OER
Laser
Eleventh graders explore the different steps in the engineering process. In this physics instructional activity, 11th graders design an experiment based on topic given. They prepare a presentation and share it with the class.
Curated OER
Investigating Acidity
Students classify liquids as an acid, base or neutral. They use purple cabbage juice as an indicator to test several liquids in order to group them as acids, bases or neutrals.
Curated OER
Sink or Float?
Students examine how weight and balance can effect if an item sinks or floats. They listen to the book "Who Sank the Boat?" by Pamela Allen, and discuss how the smallest animal sank the boat. Students then conduct an experiment in...
Curated OER
What are Properties of Wood?
Students use hands on scientific observation to determine characteristics of wood. They work directly with the materials and record their observations. Students test if wood absorbs water, if wood floats or sinks, and if all wood...
Curated OER
Determining pH
Students evaluate pH levels through a solubility experiment. In this pH levels lesson, students list characteristics of acids and bases. Students complete their own pH level experiment. Students go to the GEMS Alien Juice Bar website to...
Curated OER
Polymerization Experiments
Learners explain the process of polymerization. In this chemistry lesson, students produce carboxylesterase in the lab. They test its effectiveness in removing the by-product odor.
Curated OER
Starch Yer Thinkin' About Corn Products
Seventh graders study the parts of corn and explore the role of starch. In this corn products lesson students prepare a model of water and stones.
Curated OER
Acid Rain Research
Students collect samples of rainfall, cloud condensation, and water that trickles through the soil. These samples are tested for pH, conductivity, and the presence of sulfates, nitrates, calcium, and magnesium.
Curated OER
Amylase Enzyme In Saliva
Students test for amaylase enzyme in a variety of substances. Student pairs perform a series of tests to determine how long it takes the starch sample to change to sugar molecules and the blue color to disappear when various saliva...
Curated OER
Maple Syrup Production
Students examine the steps of maple sugar production and the labor and effort involved from the tree to the final product. They participate in a taste test game, and if they have access to maple trees, make their own syrup and sugar.
Curated OER
Electric Circuits
Fourth graders investigate complete and incomplete circuits. Using an electrical kit that includes a D-cell battery, wiring, and a flashlight bulb, they construct a complete electric circuit that will light the light bulb. Students...
Curated OER
Which Way to Grow?
Students diagram and discuss the effect of gravity on the growth of plant roots. Designed to demonstrate the role that the growth hormone auxin plays in the direction of root growth. They set up the experiment to test their hypothesis...
Curated OER
Newton II; Slow Down
Students, in hands-on activities, explore how a dump truck might be made to negatively accelerate or slow down. They participate in activities using friction force to modify the truck-and-ramp system. Student groups test ideas for...
Curated OER
Starch is Everywhere
In this science activity, students add a few drops of iodine solution to each of 10 substances to determine if they contain starch. The iodine will turn blue if the item contains starch.
Curated OER
Heat Retention
Students test 4 materials to see which would be best for use as a heat mass. They then graph the temperature verus the time of the substances and decide which material would make the best heat mass.
Curated OER
Oobleck Versus Gloop
Second graders explain that we use our senses to make observations and that the observations often describe properties of an object or substance. They make oobleck, then perform a series of tests on it.
Curated OER
Measuring Acceleration
High schoolers create an accelerometer and take measurements of acceleration in a moving car. They study the car speeding up in a straight line, slowing in a straight line and curving at constant speed. They prepare a lab report showing...
Curated OER
Classroom Content
Students examine the roles that scientists and government agencies play in protecting citizens from commercially produced chemicals. They watch a video, conduct Internet research, and prepare a media presentation.
