Coloring pages showcase microbes—bacteria, viruses, and protists. Scholars have the option to download a coloring book and scavenger hunt or color the page directly on the computer. Three paragraphs describe each microbe. 

Change the density of water by adding minerals. The presentation discusses density—from the definition to calculations—and applies it to the real world. It briefly mentions specific gravity, and finishes by showing Archimedes'...

Orange you glad you can make circuits using fruit? Young electricians learn about electric circuits and electricity. As part of the instructional activity, they build a circuit with an orange and then with a banana.

For this home energy audit worksheet, students answer 6 questions about power and how work and energy are related to power. They rank the amount of power consumed from lowest to highest for 5 household items.

Students participate in an activity in which they observe a ball as it rolls down an incline into a cup. They take measurements and use equations that describe the concepts of mechanical energy, work and power, momentum, and friction. ...

Students experience work and power and observe the process of entropy. In this physics instructional activity, students conduct an experiment that shows work (force & distance), power (work/time), and exemplifies the process of entropy.

Investigate the prospect of wind as a renewable resource. Second and third graders make a pinwheel, answer critical thinking questions, and then attempt to use wind power to wind string. I would be more apt to use this lesson in a 1st or...

Introduce your class to the workings and parts of a battery-operated circuit. Pairs of pupils use lemons to make batteries and measure voltage and current with a multimeter. An accompanying worksheet is used for recording values and...

To prepare for the activity, STEM classes read about nanotechnology and the amazing properties of graphene. They collect a graphene sample from pencils, and then connect them into simple circuits to determine whether it makes a better...
