Change in Temperature: Exothermic Reaction
Source Institutions
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.

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

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

Cup Speaker
Source Institutions
Make your own speaker with a magnet, wire, and paper cup! If you have a radio with a headphone plug and an old pair of headphones, this is a great tinkering activity.

Insulation Station
Source Institutions
In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

Soap-Film Interference Model: Get on our wavelength!
Source Institutions
By making models of light waves with paper, learners can understand why different colors appear in bubbles.

If You Lived in a Forest
Source Institutions
This activity encourages learners to focus on the natural environment of the Eastern Woodlands before the arrival of European settlers.

Paint by the Numbers
Source Institutions
In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

Design a Landing Pod!
Source Institutions
In this team design challenge (page 11-18 of PDF), learners design and build a Landing Pod for a model Lunar Rover (previously built in activity on page 1-10 of PDF).
Giant Museum: Create a Scale Model
Source Institutions
In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?

A Towering Achievement
Source Institutions
In this experience, learners use the internet to research physical details about Chihuly's Fireworks of Glass "Tower" and "Ceiling" and consider the decisions Chihuly had to make as he was planning th

Thymus DNA Extractions
Source Institutions
This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.

Chemistry Cake
Source Institutions
In this exciting and tasty chemistry activity which requires adult supervision, learners explore how chemistry affects a simple everyday activity like cooking.

Tired Weight
Source Institutions
Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

Discovering Rainforest Locations
Source Institutions
In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.

The Legend of the Flying Frog
Source Institutions
In this activity, learners listen to a story about a made-up endangered species--a flying frog! Learners print out six story pages and then draw the pictures and write the captions.

Fish Mouths
Source Institutions
This activity (page 2 of the PDF under SciGirls Activity: California Fish) is a full inquiry investigation into environmental adaptation.

Print Hints
Source Institutions
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.

Resonant Rings
Source Institutions
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.

Bone Basics
Source Institutions
This is an activity (on page 2 of the PDF under Bone Regrowth Activity) about the two main components of bone - collagen and minerals (like calcium) - and how they each contribute to its flexibility a
