In this activity, learners make "solar cookies," edible models of the Sun's outer layers using sugar cookies and toppings.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

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

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

In this activity, learners discover how a super-absorbing material can be used to move a straw.

In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.

In this activity, learners will discover what it takes to be a frog. By dressing up like one, learners can visualize how each part of the frog plays an important role in surviving its habitat.

In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

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

Most people will break a bone in their body at some point in their life, but how much force does it take to break one?

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

In this activity, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.

In this activity, learners look at and touch marine animal skulls to compare them and think about what they eat.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

This activity encourages visitors to build an electroscope—a simplified version of one of the tools scientists use to study the invisible forces on Earth and in space.

"Molecules in Motion" explores how materials behave and change in a vacuum.

This fun and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.
