In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.

In this activity, learners develop their understanding of combinations as they create as many different kinds of tostadas as possible.

In this math activity, learners play a probability game and try to be the first to get to the end of the game board path .This activity guide contains a material list, black line masters for the game

This activity was designed for blind learners, but all types of learners can explore the three states of matter by examining tactile models that illustrate the characteristics of particles in each sta

In this activity, learners add squares to paper dominoes to make polyominoes.

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

In this activity, learners explore the relative sizes and distances of objects in the solar system.

In this artistic activity, learners blow up a smaller picture into a larger one, by using a grid.

In this activity, learners will explore probability using dice. They will predict and then roll the dice to observe how many rolls it would take to repeat a matching pair. Learn track predictions vs.

In this craft activity, learners will recognize, name, and compare the fractions 1/2, 1/4, and 1/8 by constructing a penguin out of portions of paper circles.

In this activity (2nd activity on the page), learners explore the sensitivity of their sense of touch.

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.

In this activity, learners find as many combinations of a hundred as they can using various puzzle pieces from a hundred square grid paper.

In this game, learners strategize to win the most cards by building number equations. Learners practice operations (addition, subtraction, multiplication, and division) to construct their equations.

In this math game (Page 9 of the Are You Game? PDF), learners determine what makes a spinner fair or unfair. Learners first play a round with a pre-made spinner that isn't very fair.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.

In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.

How far can you see out of the corner of your eye? Grab a partner and find out from the Exploratorium Science Snack.

In this activity, learners make a barometer, an instrument to measure change in air pressure.
