Curated OER
Solar
Students study solar energy. In this renewable energy lesson students complete several lab activities using different controls and variables.
Curated OER
The Great Gas Race
Fourth graders improve their understanding of Graham's Law by using properties of gases to evaluate the rate of effusion of two compounds as they vaporize. They engage in a lab which elevates their understanding of the properties of gases.
Curated OER
What is Matter?
Students investigate what matter is and how it changes states. In this physical properties lesson, students examine the vocabulary database and identify the characteristics of the three phases of matter. Students perform a...
Curated OER
Animals of the Fire Ice
Students examine ocean life by identifying methane hydrates. In this ocean life lesson, students research organisms that live in the coldest, deepest parts of the ocean and live off methane hydrates. Students create a group...
Curated OER
Biodegradability
Students study the effects of water, salt water and heat on common household materials. They separate an emulsion and show that the materials are completely recoverable and observe the effect of acetone and water on polystyrene.
Curated OER
Water and Polymers
Students conduct qualitative and quantitative investigations based on the interaction between water and various polymers. They determine the percent moisture contained in various plastics along with a qualitative procedure to determine...

Making Model Microfluidic Devices Using JELL-O
Nothing flows like J-E-L-L-O! In the final portion of a four-part series, pupils create scale models of microfluidic devices out of gelatin and bendable straws. They use their devices to test various flow rates in the delivery of...
Curated OER
Intrinsic Viscosity
Students treat a high molecular weight polyvinyl alcohol polymer with potassium periodate. They measure the viscosity of polyvinyl alcohols.
Curated OER
Animals of the Fire Ice
Students study ice worms and describe how they interact with other species. In this methane hydrate lesson students study ice worms and hydrate shrimp to learn their behavior and can participate in an optional activity.
Curated OER
The Influence of Carbon Dioxide on the Chemistry of Soda
Students investigate the carbon dioxide content of different sodas. In this chemistry lesson, students explain why PET containers are preferable than HDPE for soda bottles. They collect data and graph them.
Curated OER
Carbon Dioxide
Students conduct a series of experiments to explore carbon dioxide properties. In this chemistry instructional activity, students explain the production and uses of this gas. They measure its amount in soda and waste product of yeast.
Curated OER
Limiting Reagent
Students work in small groups with a small set of 8 nuts and 5 bolts to assemble into combinations of 1 nut: 1 bolt, and 2 nuts: 1 bolt. They explore the outcome and discuss. Then a student mixes two clear, colorless solutions together...
Curated OER
Teaching the Scientific Method Using Adhesives
Students research on the history of adhesives. In this science lesson, students select one test to use in finding the stickiness of adhesives. They collect data and formulate a conclusion.
Curated OER
Amylase
Students examine what amylase is and its history. For this digestive lesson students study the effect amylase has on starch and how temperature affects the rate of activity.
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
Synthesizing Pigment and Dyeing Cloth
Young scholars create a synthetic dye and oxidize the dye and record the effects.
Curated OER
Micro-Magic With Sticky Ions
Students view a video about the formation of precipitates. They complete a worksheet that asks them to identify what makes a compound form and what holds it together.
Curated OER
Teaching The Scientific Method Using Adhesives
Young scholars use the six step scientific method to experiment with the differences in adhesives. Students test for tack, shear, and peel in these activities.
