In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

In this activity, learners explore the concept of how brakes can stop or slow mechanical motion.

In this lab (Activity #1 on page), learners explore how we see color.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).

In this hands-on activity, learners investigate the functional design of leaves on a tree.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.

In this activity, learners create a mixture of water, alcohol and permanent marker ink, and then add salt to form a colored alcohol layer on top of a colorless water layer.

This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

In this activity, young learners use their sense of touch rather than sight to identify a mystery object in a bag. Learners take turns acting as "peekers" and "sensers" throughout the game.

In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

Learners shine the light of a laser pointer through sheets of fabric that all have a different number of threads per inch.

In this genetics activity, learners discover how to extract DNA from green split peas.

In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.
