In this activity, learners will explore engineering to construct an insect collecting tool (insect aspirator). The pooter uses suction to safely collect smaller insects that nets miss or may injure.

In this activity, learners will experiment with the physics of forces - kinetic energy and friction while making a moving toy woodpecker.

In this activity (on pages 19-21 of the PDF) learners observe mold growing on potatoes. Preparation for this activity has to start a week before, to allow time for the mold to grow on the potatoes.

In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

Learners design different shaped bandages for different purposes. First, they draw their designs on paper.

In this activity, learners will construct a measuring device (snake "string") to improve their observation skills.

We listen to stereo music systems, tv's, and radios because it simulates being where the sound originates.

In this activity, learners will create their own coral polyps - the basis for a coral reef.

In this activity (14th activity on the page) about the sense of touch, learners examine if it is easier or harder to identify an object if they move their hands over it.

“Exploring the Universe: Imagining Life” is a hands-on activity in which visitors imagine and draw an extreme environment beyond Earth, then invent a living thing that could thrive in it.

Break open that used musical toy and squish some Play-Doh over the circuit boards, and you will hear some weird and distorted sounds the manufacturer never intended!

In this activity, learners will experiment with the physics of flight by making a gliding contraption with strange looking wings. The activity explores flight with connections to the natural world.

In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.

This is a guide for facilitating interaction at a touch tank with marine animals. The instructions are for setting up a display in an informal science center, but could work anywhere.

Create an instrument that you don't play--you just listen to it through tubes of various lengths.

In this activity, learners will build a bee hotel for pollinators. Learners will explore building and ecology through this activity.

Look at pictures through different color filters and you'll see them in a new way. People have used color filters in beautiful photography or sending secret messages.

In this activity, learners will estimate how many seeds are in a fruit or vegetable, then count to find out. The result: mix estimation with healthy eating.

We don't normally view people upside down and so our brains aren't accustomed to it.
