Growing Rock Candy
Source Institutions
In this activity, learners make their own rock candy. Crystals will grow from a piece of string hanging in a cup of sugar water. The edible crystals may take up to a week to form.
Solar Convection
Source Institutions
In this activity, learners add food coloring to hot and cold water in order to see how fluids at different temperatures move around in convection currents.
Finding the Sweet Spot
Source Institutions
In this activity, learners will discover how to find the "sweet spots" on a baseball bat. Whenever an object is struck, it vibrates in response.
Paper Sculptures
Source Institutions
In this activity, learners manipulate paper to build original 3-dimensional sculptures. Appropriate for any age, learners can use fingers to tear, crumple, or fold, and if available, scissors to cut.
Big Banner Mural
Source Institutions
This activity is about the mural making process done about 9,000 years ago in Catalhoyuk, Turkey.
Introduction to the Scientific Method
Source Institutions
In this activity (page 26 of the PDF), learners make observations, formulate hypotheses and design a controlled experiment, based on the reaction of carbon dioxide with calcium hydroxide.
Make Pan Pipes
Source Institutions
This is a simple activity for learners to create a traditional musical instrument. Pan Pipes have developed all over the world in different cultures, from South America to Greece and China.
Building a 3-D Space Maze: Escher Staircase
Source Institutions
In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about
Space Origami: Make Your Own Starshade
Source Institutions
In this activity, learners cut out and fold their own collapsible origami starshade, an invention that shields a telescope's camera lens from the light of a distant star so that NASA scientists can ex
Build the Big Dipper
Source Institutions
Learners use simple materials to construct a model the Big Dipper. Learners hang the model from a doorway or ceiling and look up at it to see the constellation as seen from Earth.
A Slice of Apple Fly
Source Institutions
In this activity, learners build an instrument for catching and observing flies. Learners act as entomologists, attract flies into a jar using a slice of apple, and then observe the flies' behavior.
Swell Homes
Source Institutions
In this outdoor activity, learners find the swollen bumps known as "galls" on various plants and get a closeup look at the parasitic animals living inside.
Paper making: a craft and a chemical engineering major
Source Institutions
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.
Taking Its Temperature
Source Institutions
In this activity (pages 5-7), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
Geyser
Source Institutions
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.
Paperfolding Polyhedrons
Source Institutions
In this activity (on pages 55-66 of PDF), learners fold paper into origami shapes and then combine several identical shapes into a three-dimensional structure.
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.
Cipher Wheel
Source Institutions
In this activity, learners make their own encrypted code to pass along secret messages using a printable cipher wheel.
AM in the PM
Source Institutions
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.
Balloon Staging
Source Institutions
In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.
