• • Great Solar Power Experiment!
  Add Sticky Note
• In this activity, students learn how engineers use solar  energy to heat buildings by investigating the thermal storage properties of some  common materials: sand, salt, water and shredded paper. Students then evaluate  the usefulness of each material as a thermal storage material to be used as the  thermal mass in a passive solar building.

• Summary: In this problem-based  learning activity, students experiment with a battery and light bulbs to build  your own flashlights. The purpose of the activity is to develop understanding of  fundamental electrical circuit concepts, including voltage, current, and closed  circuits, and to help eliminate common misconceptions. This module provides  instructor information for the activity.

• • Offers a video for electricity with key vocabulary.

• How Do  You Get Electricity From a Cow?
  Students  are given a clue before they select their answer to this riddle. In the text and  video clip for the clue, two children tell about their unsuccessful attempt to  use a pet cow to spin the metal coil in a generator. Students are given three  answer choices. Brief feedback is given for the incorrect choices. When students  select the correct answer, they can watch a short video clip of a farmer  explaining how his farm generates more power than it needs by making use of the  methane gas released from decomposing manure.

• • This is a video great for upper elementary and learning about electricity. It is also something that students can do!
• Testing for Static Electricity
• In this video segment adapted from ZOOM, cast members test for the  presence of static electricity using a device called an electroscope. Viewers  learn that rubbing certain materials together causes electrical charges to build  up on the surface of one of the objects and that charge moves easily through  conductors but not through insulators.

• • audio and video clips!
• The video posted with the Science Friday story Harvesting  Energy From Walking illustrates this nicely in slow motion  segments. Color labels identify the key events in the process.
• Here are some additional resources that are part of the NSDL Middle School Portalcollection  to facilitate your instruction regarding energy sources and conversions: Energy  Transfers; Quick Take  
• on The  Power of Electricity; and Quick Take on  Energy Sources.
