In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

In this activity (on pages 2-8), learners experience how scientists use classification in their study of animals.

In this activity, learners will discover why there are holes in bread.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity (on page 2 of the PDF), learners make a plastic protein polymer from milk. Adding vinegar to milk causes the protein casein to solidify or curdle.

In this activity, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.

In this activity, learners add dilute bleach solution to water that has been dyed with yellow, blue, and green food color.

In this activity, learners make balloon models of disease-causing bacteria.

In this activity, learners separate the protein from milk and and use it to make their own glue.

In this fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

This lesson gives full instructions for making cabbage juice indicator, a procedure sheet for learners to record observations as they use the indicator to test materials, and extension activities to d

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

Learners explore capillary action in plants (such as plants ability to move water from roots to leaves) in an investigation called Paper Blooms.

Learners use a simple process to extract DNA from strawberries.

In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi

In this activity, learners mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow.
