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, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

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.

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

Learners use a simple process to extract DNA from strawberries.

In this challenge, learners figure out how to make a juice stain disappear.

In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.

In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.

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.

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, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

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

In this activity, learners explore the properties of metals at four stations. The stations include A) Magnetism and Breakfast Cereal; B) Conductivity of Metals; C) Alloys; and D) Metal Plating.

In this activity on page 4 of the PDF (Behind the Scenes with Chemistry), learners make some special effects, including snow and breaking glass, with supplies found in the home.
