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

In this activity, learners explore the "nuts and bolts" of gene chips.

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 data activity, learners analyze data from coral reef snapshots taken by scientists at the Virginia Institute of Marine Science.

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

This activity helps students learn how computers "compress" text by identifying repeating patterns of letters, words, and phrases.

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

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

This is an educator-led demonstration of microarray technology using a model created from a pizza box and ping-pong balls.

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

In this technology activity, learners build an "alarming" doormat to keep siblings out of their rooms. Use this activity to teach learners about circuits, switches, and sensors.

In this design challenge activity, learners investigate series circuits and motors to build a hand-held "kick stick." Their goal is create a battery-operated device that sends a Ping-Pong ball across

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

This is a quick game about self-assembly (page 2 of PDF under Self-Assembly Activity). Like the molecules of DNA, learners will self-assemble into a pattern by following a simple set of rules.

In this math activity, learners find patterns in telephone numbers.

In this quick activity about pollutants and groundwater (page 2 of PDF under Water Clean-up Activity), learners build a model well with a toilet paper tube.
