In this activity, learners build a game that tests their steadiness. Learners construct the game board by setting up an electrical circuit and a wand.

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.

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

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

In this activity, learners use a simple 3D model to discover why the Moon has phases.

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 (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners use oil, water, food coloring and antacid tablets to create a bubbling lava lamp. Use this activity to introduce concepts related to density, hydrophobicity vs.

During this activity, learners will make different versions of "ooze" using varied proportions of detergent and glue.

In this activity, learners build a switch to turn electrical circuits on and off.

In this activity, learners draw natural objects to explore the details, differences, and similarities of natural objects.

In this activity, learners make edible T. rex teeth (with adult assistance). The treat is a white and dark chocolate covered banana on a stick.

In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

In this activity, learners practice matching and subitizing as they create the longest domino train possible.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.
