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.

In this activity, learners use a pencil, magnets, and mat board to illustrate Newton's Second Law.

In this activity, learners create their own weather forecast map.

In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.

In this design activity, learners create a vehicle that can transport a load, like a favorite toy or as a recycled object, from the top of a zipline to the bottom using only gravity.

In this activity, learners use beads, which represent amino acids, to create protein bracelets. Learners examine the relationship between amino acids and proteins.

In this activity, learners will explore how light can refract or break apart into different colors.

In this physical sciences activity, learners explore how forensic investigators collect prints from a crime scene. Learners make hand impressions in damp sand and analyze the patterns they observe.

In this activity, learners explore the question "What is paper?" Learners discover the processes and materials required to make paper while experimenting with different recycled fibers and tools.

In this activity (pages 5-7), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

This Exploratorium activity can be used in many contexts because geysers are great opportunities for learning about heat and temperature changes as well as geological/space science phenomena.

In this activity, learners will explore how their own eyes work by experimenting with their photoreceptors.

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

String Thing is an interactive online game in which learners change a virtual string's tension, length, and gauge to create different musical pitches.

Things that are different sizes and stiffness vibrate differently, and in this Exploratorium Science Snack, you'll see how rings of various diameters react to vibration and external forces.

En esta actividad, Mateo y Cientina descubren una sustancia nueva y extraña que se llama "Oobleck". En su experimento ven que Oobleck tiene propiedades de sólidos y líquidos.

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.

In this activity, learners will build an air cannon out of simple materials you can find around the house. Although air is invisible to the eye, it is not by any means empty space!

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.
