Squash Dissection
Source Institutions
In this activity, learners will dissect a pumpkin or winter squash to learn the parts of the plant. This activity gets your learner hands on with every part of the plant and will be messy.
Kites
Source Institutions
In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.
A Merry-Go-Round for Dirty Air
Learners build a model of a pollution control device--a cyclone. A cyclone works by whirling the polluted air in a circle and accumulating particles on the edges of the container.
Eclipse Flipbook
Source Institutions
In this activity, learners make flipbooks of drawings showing the progression of a Total Solar Eclipse.
Shoe Dichotomous Key
Source Institutions
In this activity (on page 2 of the PDF under GPS: Cactus Activity), learners will develop their own version of a tool used by biologists, a dichotomous key, by collecting all their left shoes.
Crayfish Investigations
Source Institutions
This activity has learners interacting with live crayfish, but could be adapted for a variety of similar hardy and interesting organisms.
Does Size Make a Difference?
Source Institutions
In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.
Exploring the Solar System: Mars Rovers
Source Institutions
In "Exploring the Solar System: Mars Rovers," participants learn about how scientists and engineers use robotic rovers and other vehicles to explore distant worlds, and experience some of the challeng
Ziptop Bag Chemistry
Source Institutions
In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.
What Causes Wind?
Source Institutions
In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.
DNA Extraction from Cheek Cells
Source Institutions
DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique.
DIY Sunprints
Source Institutions
In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.
Ten, Twenty, Thirty
Source Institutions
This game for one to four players uses a deck of cards to develop mental addition skills.
Create Your Own Decoupage
Source Institutions
In this activity, learners will experiment with textures, shapes, and materials and create their own unique masterpieces.
New Sense about Cents
Source Institutions
In this activity on page 6 of the PDF (Chemistry—It’s Elemental), learners explore some of the properties of copper using a few common household ingredients.
Earthquake Science: Soil Liquefaction
Source Institutions
This activity demonstrates liquefaction, the process by which some soils lose their solidity during an earthquake.
Spit Test
Source Institutions
In this biology activity (page 8 of the PDF), learners will explore how saliva assists in the beginning of the digestive process.
"Baseketball": A Physicist Party Trick
Source Institutions
This trick from Exploratorium physicist Paul Doherty lets you add together the bounces of two balls and send one ball flying.
Hidden Alarm
Source Institutions
In this design challenge activity, learners invent a device that will make their friends and family ask, "What's buzzing?" Learners design an alarm with an on/off switch that is small enough to hide.
What does Color have to do with Cooling?
Source Institutions
In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.
