Gumdrop Dome
Source Institutions
In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.
Radioactive Decay of Candium
Source Institutions
In this simulation, learners use M&M™ candy to explore radioactive isotope decay.
Kool Colors
Source Institutions
Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.
Spaghetti Bridge
Source Institutions
In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.
Wave Machine
Source Institutions
This is a great activity about wave interference. Learners will create their own wave machine and discover wave properties through hands-on investigation.
Evaporation
Source Institutions
This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.
Secret Codon
Source Institutions
In this activity, "write" a secret message in genetic code as beads on a string.
Comparing the Density of Different Liquids
Source Institutions
Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.
Animal House
Source Institutions
The goal of this activity is to design, build and test a house or toy for an animal.
Hidden Color Chemistry
Source Institutions
In this activity, learners will discover what colors are in different markers, and may be surprised at the results.
Bouncing Balloons
Source Institutions
In this sports-themed engineering activity, learners create super bouncy balls out of balloons. Learners brainstorm, test their designs, and share results.
Running in Circles
Source Institutions
In this group activity, learners use some common objects and work together to simulate the Coriolis effect. During the challenge, learners make predictions and test different scenarios.
Pollution and Lung Health
Source Institutions
Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.
Paper Towel Strength
Source Institutions
In this activity, learners will test the strength of different brands of paper towels.
Four Corners
Source Institutions
In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.
Helping Hand
Source Institutions
In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.
Tumble Wing Walkalong Glider
Source Institutions
In this physics activity (page 2 of the PDF), learners will construct their own walkalong glider. They will explore how air, though invisible, surrounds and affects other objects.
Make a Speaker: A Coil, a Magnet, and Thou
Source Institutions
Make your own simple speaker so you can listen to your favorite radio station. Just wind a coil, attach it to a piece of cardboard or Styrofoam, hold a magnet nearby, and listen.
Micro Automata
Source Institutions
In this activity, learners build small animated toys that move.
Hot Air Balloon
Source Institutions
In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.
