Curated OER
Comparing Light Bulbs
Fifth graders compare filaments in different light bulbs. In this science lesson, 5th graders view the filaments of light bulbs under a microscope.
Curated OER
Make An Egg Float!
Students analyze density. In this density activity, students experiment with floating an egg. Students discover that salt added to water changes the density of the water allowing an egg to float.
Curated OER
What is a Sound?
Second graders explore the concept of sound. In this sound lesson plan, 2nd graders discover what sound, vibrations, and pitch are through several experiments. Students watch a Power Point presentation that allows them to complete a...
Curated OER
Stoichiometry
Students research chemical formulas and balance chemical equations. In this chemical equations lesson students complete a class activity on chemical equations and answer questions.
Curated OER
A Model of a Scanning Tunneling Microscope
Ninth graders explain how a scanning tunneling microscope works. In this chemistry instructional activity, 9th graders construct atomic models and simulate how their images appear under the STM. They discuss the limitations of their...
Curated OER
Lactose & Lactase
Students examine the characteristics of lactose and lactase. In this enzyme lesson students study the lactose in milk and its rate of dissolution.
Curated OER
Why is the Sky Blue?
Students explore diffusion or scattering of light. In this physics instructional activity, students explain why the sky is blue and sunsets/sunrises are red.
Curated OER
Corrosion & Rust
Students examine how and when rust and corrosion occur. In this corrosion instructional activity students complete an experiment to see why metals rust.
Curated OER
A Comparison of Polymeric Liquids with Newtonian Liquids
Students perform several tests on liquids. In this general science lesson, students compare the properties of polymeric and nonpolymeric liquids. They explain the composition and importance of macromolecules.
Curated OER
Thermoset Polymers
Young scholars complete a lab activity with polymers to allow them to better understand how to make "observations". In this science lesson students make measurements and collect data.
Curated OER
Temperature and Enzymes
Students compare the times it takes the milk in each of two cups to curdle. They are told that an enzyme that is added to the milk, rennin, is involved in the natural curdling process of milk. Students are asked to consider what...
Curated OER
Electrical Energy
Students conduct an experiment to find out how well different wires radiate heat when voltage is applied across the wire. They use the results of their experiments to consider how the gauge of the wire and the type of wire affect the...
Curated OER
Let the Sunshine in
Students collect and analyze data to study wavelengths of visible light. They cover Styrofoam cups with three different colors of sun filtering products and shine a lamp directly on the cups. They determine the most effective filtering...
Curated OER
Vitamin C Testing
Pupils determine which of three beverage samples contains the most vitamin C. They then apply their knowledge to an additional situation. Students use beverages that have a large, definite difference of vitamin C content to facilitate...
Curated OER
Hydrated Salt
Students plan, design, and carry out an experiment to determine an empirical formula for a hydrated salt X that tell students when all the water has been removed from hydrate crystals.
Curated OER
How do plant & animal cells make and use energy?
Pupils show the relationship between the need for plants to undergo photosynthesis in order to generate oxygen. They see the flaws associated with this thinking because of the lack of CO2 and H2O and lack of sufficient gravity in order...
