Make a Green Gumball Black
Source Institutions
In this optics activity, learners use a shoebox, colored cellophane and sunlight to "change" the colors of gumballs. Learners will be surprised when the green and blue gumballs appear black!

Secret Messages
Source Institutions
In this activity, learners use Teflon (PTFE) tape to write secret messages.

Carrying Charges: Testing for Conductivity
Source Institutions
Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).

Slide Whistle
Source Institutions
In this activity, learners build a slide whistle using PVC pipe, bamboo skewer, and piece of foam. Construction of the instrument is relatively simple.
Tree Poker
Source Institutions
In this activity (p.14-15 of PDF), learners discover the concepts of competition and limiting factors as they relate to plant and animal communities.

The Turing Test: Conversations with Computers
Source Institutions
This activity aims to stimulate discussion on the question of whether computers can exhibit “intelligence,” or are ever likely to do so in the future.

Exploring Fabrication: Self-Assembly
Source Institutions
In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.

Space Elevator
Source Institutions
In this activity, learners imagine what the world might look like if we could build an elevator to space!

Make a Lake
Source Institutions
Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

Electroscope
Source Institutions
In this activity about electricity, learners suspend pieces of tape from a straw to construct an electroscope, a device that detects an electrical charge.

Kidbots
Source Institutions
In this activity, one person acts as a human robot while another acts as their developer by programming their actions.

Sweet Speedway
Source Institutions
In this activity, learners test different food items by timing how long it takes each liquid to slide from the top of a ramp to the bottom.

Safe in the Sun
Source Institutions
In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.

Measure the Sun's Size
Source Institutions
In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

Pictures From Light
Source Institutions
Did you know that using a lens one can bend light to make pictures of the world? It's true!

Flip
Source Institutions
In this amazingly simple physics activity (page 5 of the PDF), learners will explore how exerting a force on an object can give it kinetic energy and momentum.

Paint a Fresco
Source Institutions
In this activity on page 7 of the PDF, learners experiment with the interesting designs that can be made by painting on plaster.

3 Classes of Levers
Source Institutions
In this physics activity (page 3 of the PDF), learners will move a load using a lever of each of the 3 classes. They will explore the differences between these classes and which are more effective.

Exploring Magnetic Field Lines
Source Institutions
In this activity, learners explore the magnetic field of a bar magnet as an introduction to understanding Earth's magnetic field. First, learners explore and play with magnets and compasses.

The Face of Science
Source Institutions
Learners draw pictures of how they envision scientists. By comparing and discussing the features in their pictures, they can discover common thoughts and stereotypes about scientists.
