In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

In this activity, learners smell bottles containing bee pheromone molecules (or herb/spice extracts as a substitute). Bees release these molecules to send messages to each other.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

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

In this activity, learners estimate risks associated with different events and compare their estimates to the real possibilities.

In this activity, learners use simple materials to create giant bubbles.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.

Learners use a mortar and pestle to extract clove oil from cloves using denatured alcohol. They put this oil on paper, which they can take home.

In this fun and in depth hands-on experiment, learners test various liquid samples (distilled water, lemon juice, vinegar, and baking soda mixed with water) to determine their pH levels and identify e

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

What's a Pickle-Oh? Two pieces of pickle on a stick are connected to a Pico Cricket (micro controller). When you slide the pickles apart the note changes.

In this activity, learners make a photographic image—without a camera!

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this activity about olfaction (8th activity on the page), learners smell 10 different items with different odors. Then they try to identify the smells when they are mixed together.

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

In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.

In this activity (4th activity on the page), learners test to see if saliva is necessary for food to have taste.
