There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...

Given a variety of rocks, junior geologists calculate densities and correlate them to Earth's layers. As a simulation of continental crust, they experiment with how materials of differing density float in water. Finally, they...

How can organisms light up in water? Bioluminescence is light produced in a chemical reaction that can occur in an organism's body. First, learners determine what happens to light/color as you move into the deep ocean. In groups, they...

Students perform varied activities as part of a layered curriculum unit: They write and perform a skit that outlines the evolution of the model of the atom. The script is submitted to the teacher for review before performance.

Eighth graders identify the different types of rocks. In this earth science instructional activity, 8th graders compare and contrast rocks and chocolate cookies. They explain how materials are recycled beneath the Earth.

Fourth graders examine the history of the tortilla and extend the study across the curriculum. In this history of the tortilla lesson, 4th graders research the background of the tortilla, determine the ingredients, and work with the...

Students test commercial sunscreens or sunglasses for accuracy of their Sun Protection Factor. They devise a method for testing UV beads with a visual clues which they publish as research. They investigate occupations such as...

Students consider the concept that plants and animals are dependent on one another and role-play the interaction between bees and flowers. They identify crops that are dependent on pollination by bees.

Students study plant and animal interdependence by studying bees and pollination. In this interdependence lesson, students discuss flower parts and dissect it to show its reproductive parts. Students then use tissue and pipe cleaners to...

Third graders examine what makes soil by creating a Venn Diagram.  In this Earth environment lesson plan, 3rd graders identify the different components that soil is made from. Students bring soil from their homes to examine and...
