This activity teaches combustion as the interaction of a fuel source and oxygen.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

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

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

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 about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

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

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners collect, categorize, weigh and analyze classroom trash and discuss ways that engineers have helped to reduce solid waste.

Learners develop an understanding of air pressure in two different activities.

Learners use a simple process to extract DNA from strawberries.

In this activity on page 8 of the PDF (Behind the Scenes with Chemistry), learners make three of Harry Potter's essential school supplies: quills, ink, and color-changing paper.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

This experiment allows learners to experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables learners to determine the originator of the "epidemi

The objective of this inquiry-based lesson is for learners to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.
