In this math-based activity, learners will experiment to find how height and angle affect spatter and then use this knowledge to solve a crime.

In this activity, learners will explore how and why weight distribution works.

In this activity, learners explore center of gravity, or balance point, of stacked blocks.

In this activity, learners will explore two-dimensional shapes that are found in three-dimensional shapes. Learners will explore geometry, design, color and tool use through this activity.

In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

In this math activity, learners observe and sketch cracking patterns in pavement.

This activity was designed for blind learners, but all types of learners can utilize it to investigate volume, mass, and density.

How do you measure a bubble when it's floating? You can't really, but in this activity, learners can measure the diameter of the ring of suds a bubble leaves on a flat surface.

Did you know that you would be a different age if you lived on Mars? It's true!

This trick from Exploratorium physicist Paul Doherty lets you add together the bounces of two balls and send one ball flying.

This is a classic exercise for visualizing the scale of the Solar System.

In this math activity related to light, learners explore why a light, such as a candle or a streetlight, looks dimmer the farther away from it we get.

Learners can program a compass to draw a circle by itself using a Pico Cricket, some Legos, and lots of tape! Pico Cricket is required.

In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this activity (page 18 of PDF), learners will measure the volume of impact craters created by projectiles of different masses.

In this life science activity (page 8 of the PDF), learners explore the carbon cycle by mixing yeast, sugar and water.

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

In this activity (page 7 of PDF), learners will identify the general two-dimensional geometric shape of the uppermost cross section of an impact crater.

In this activity (page 10 of PDF), learners approximate the area of the uppermost cross section of an impact crater using a variety of square grids.
