This is an activity about our sense of smell and how it compares to sharks' super noses. Learners will create varying solutions of water and perfume.

In this colorful activity (page 6 of the PDF), learners will make a multicolor density column by using different concentrations of sugar solutions.

In this activity exploring liquid dynamics, learners design and build a clay channel in a tray of water and then see what happens when food coloring and liquid soap are added to the mix.

This Exploratorium activity can be used in many contexts because geysers are great opportunities for learning about heat and temperature changes as well as geological/space science phenomena.

In this activity, learners explore the concept of density by pouring 5 different liquids into a jar. Food coloring is added if needed to give each liquid a distinct color.

In this chemistry activity (page 5 of the PDF), learners will use milk and a few other basic ingredients to create a chemical change to make a color wheel.

In this activity, learners use water, oil, and food coloring to observe a chemical reaction that creates a shower of colors inside of a glass.
