To conclude a mini unit on the dissolving of M&Ms® candy coating, this lesson investigates whether or not the concentration of sugar in the solvent affects the dissolving rate. Consider having older science learners write their own...

Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

How diverse are the benthic organisms found in local streams? Using the information learned in previous lessons on identification of macroinvertebrates and on calculating stream index values, groups determine the health of local...

For any science class, learners can use this lab sheet to plan an experiment. It includes a space for the title, question, materials, setup, and procedure. If you want your class to complete this in typed form, you can provide the web...

The size of a nanoparticle is difficult for pupils to grasp. A hands-on experiment is designed to give your classes perspective. Learners analyze different sports drinks for the content of electrolytes as an introduction to nanoscale....

Explain the importance of radioactive half-life as your high school biologists demonstrate the concept by performing a series of steps designed to simulate radioactive decay. Pupils use pennies to perform an experiment and gather data....
