In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

In this activity, learners construct a home-made journal with simple, everyday materials.

In this activity, learners will exercise their imaginations and artistic skills. Appropriate for all ages, learners will create unique pieces to jumpstart storytelling sessions.

An ordinary camera has a lens that makes an image on film. In a pinhole camera, a small hole replaces the lens.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

In this activity, learners will explore engineering concepts to construct a blanket fort using materials sourced from home.

This activity offers learners and their families several ways to raise their awareness together about home water.

In this activity, learners use simple, everyday materials to experiment with balls and ramps.

In this activity, learners will explore light with reflective surfaces. Learners will make predictions and share their observations as they experiment with directing a beam of light.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.

This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.

In this activity (11th activity on the page), learners use pennies to test their hearing acuity.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

In this activity (17th on the page), learners investigate why you cannot see colors in dim light.

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

In this quick activity/demonstration (5th on the page), learners explore depth perception.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.
