In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this activity, learners use multiple thermometers, placed at different angles, and a lamp to investigate why some places on Earth's surface are much hotter than others.

This fun and simple hands-on astronomy activity lets learners create 3D models of the Earth, Moon and Sun to demonstrate solar and lunar eclipses.

In this activity, learners of all ages will experiment with paint and printmaking.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

In this activity learners will be creating art using a traditional Japanese art style.

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

In this activity, learners make a model of a one-way heart valve to investigate how a heart controls the direction of blood flow.

In this activity, learners will create their own simple shadow puppets, and experiment with light and shadow while playing with them.

In this activity, learners will dissect a pumpkin or winter squash to learn the parts of the plant. This activity gets your learner hands on with every part of the plant and will be messy.

Many people get water from a source deep underground, called groundwater.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity, learners play a card game that explores the relative sizes of various objects. Learners compete to organize their hand of cards into lists of objects from largest to smallest.

Most of the time, we don't have to think about breathing. In fact, you're probably breathing right now without thinking about it!

Our bodies produce snot, or mucus, that we blow from our noses. In this activity, learners will create a model of how snot works and will explore how it keeps our bodies healthy.

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

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.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this activity, learners will use simple materials to explore centripetal force and variables by swinging a cup of water without having the water spill out.

In this activity, learners explore nonrenewable resources and learn why these resources are finite.
