In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.

In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

In this activity, learners can observe chaotic motion. A magnet tied to a piece of string makes a pendulum, which swings over three sets of fixed magnets.

In this activity, learners make their own solar oven to bake s'mores and learn about how solar energy is absorbed on Earth.

Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

In this activity, learners explore physics by building a catapult that launches marshmallows with household objects.

Learners investigate a pre-constructed mystery tube to determine its interior mechanism.

In this activity, learners will take a step back and learn the history of the land they live on, and the people who used to live on it.

In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

In this craft activity, learners create a string of cut-out moons and stars.

Using simple materials from around the house and recycled materials, learners will engineer a grabber device to pick up and put down objects that are at least 12 inches away.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.

Learners will do an experiment to determine which type of paper is strongest while focusing on variables and collecting data.

In this activity, learners will build a ball run contraption.

In this activity, learners survey living organisms near where they live or go to school, and create a local field guide.

In this activity, learners will use chemistry to create a night sky watercolor painting. They will experiment to learn the effects of mixing crayon, salt, and lemon juice with water color paints.

In this activity, learners will use their five senses to explore a nature-based area around them.

In this activity, learners will use household items to design and build an elevator that will carry 2 passengers to a height of 16 inches...or higher!

In this activity, learners use three types of cheesy snacks--cheese balls, cheese puffs, and Cheetos--to learn about polymers.
