In this online activity, learners will brush up on their multiplication, division, and factoring skills with this exciting game.

This activity was designed for blind learners, but all types of learners can explore means of physically separating a mixture using dissolving, filtration, and evaporation.

In this activity (on pages 16-21), learners get a sense of geological time by understanding how big a million is.

Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.

In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

This mirror-tracing activity related to proprioception is a visual and motor test that involves learning a new motor skill.

In this simple activity (on page 7 of the PDF), learners use water and liquid dish detergent to see which one removes lipstick better from an index card.

In this activity, learners extract DNA from their own cheek cells, then create a rudimentary DNA profile similar to those seen on crime scene dramas.

Put math of measurement into lining up — and make waiting in line fun. Choose a size characteristic that learners can physically compare, such as foot length or hair length.

In this activity, learners build a scale model of the solar system using a roll of toilet paper.

Data in computers is stored and transmitted as a series of zeros and ones. Learners explore how to represent numbers using just these two symbols, through a binary system of cards.

This activity helps learners learn about math through a real-world scenario. Three friends are baking cookies for their school’s bake sale.

In this activity, learners make different shapes that hold exactly one mole of gas (air).

In this activity, learners investigate the Earth's rotation and how to tell the time of day without a clock. Thsi simple activity only requires a paper plate, a pencil, and sunshine.

This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.

In this activity, learners create a colorful foam fountain by adding yeast to a chemical reaction. This activity introduces chemical reactions to young learners and teaches the concept of catalysts.

In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.

In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.
