Introductory Module
Third graders examine the non-standard method of measurement and compare it to the metric system of measurement. In this introductory module lesson, 3rd graders discover the scientific observation. Students also develop communication...
Curated OER
We All Start Somewhere
High schoolers demonstrate an understanding that the same data can lead to different interpretations and conclusions and that different interpretations and conclusions are not necessarily wrong, but can be useful in developing other...
Curated OER
Seltzer Breath
Learners investigate "indicator" (Bromothymol Blue or BTB) to test for the presence of certain chemicals in liquids and gases. They compare distilled water and seltzer water for presence of carbon dioxide.
Curated OER
Demonstrate Your Chemistry
Students research and evaluate chemical reaction demonstrations that are found on the web. they work in small groups to choose a demonstration that fits a particular category of reaction and then perform the demonstration for the class.

Relationships and Biodiversity
Young scholars examine diversity on the planet and the differences within a species. For this investigative lesson students complete a lab that allows young scholars to better understand the relatedness between plants.
Curated OER
Use of Digital Cameras
Students make observations of frogs by taking pictures of a frog and writing about its structual and behavioral characteristics. They insert a photo in Word and add text boxes and arrows for labeling.
Curated OER
Cracked Marbles
Fourth graders determine how weathering, specifically ice, snow, and freezing water change the Earth's surface and rocks. After completing the investigations, they explain how heating and cooling expand and contract marbles until cracks...

Temperature and Brine Shrimp Eggs
High schoolers determine the optimal temperature at which brine shrimp eggs hatch and develop. They evaluate the changes, if any, which occur in a brine shrimp culture at various temperatures.
Curated OER
Transpiration
Students explore what affects the rate of transpiration in plants. They measure the rate of transpiration and analyze variables and additional factors that might slow or speed up the rate of transpiration.
Curated OER
Exploring Ecology
Students explore the basics of ecology through numerous hands-on and relevant activities. They participate in an online food chain demonstration, which explores food web dynamics. They dissect owl pellets, examine the prey's bones, and...
