Encourage your classes to be laundry helpers! Learners explore the chemistry of stain removal with a lab investigation. By identifying the components of the stain, they identify the most effective solute for its removal.

Learners use the net they make to dip macroinvertebrates at or below the surface. The flat side of the net allows pressure on the substrate so that organisms do not escape under the net. Two students hold onto the handles and submerge...

In this light worksheet, students construct a pinhole viewer using a paper box, wax paper, tape and a pushpin. They answer six questions about their observations, the orientation of the images they saw, and the results of their experiment.

Students investigate the strength of solutions. In this scientific inquiry lesson plan, students examine various solutions of food color and water as they discover the concentration of the solutions by adding bleach to clear the color.

Students begin the lesson by completing a survey about how much and what types of water they drink on a daily basis. Using a worksheet, they calculate the amount of water an American uses each day and the amount their own family uses. In...

Third graders model the tag and recapture of bears and use proportions to estimate the population of the bears in their forest. This is a statistical sampling method used by scientists and naturalists to determine population numbers.
