Light and Dark
Source Institutions
Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.
Shrinking Cups
Source Institutions
This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.
Arrows
Source Institutions
In this activity, learners surprise their eyes with an optical illusion involving arrows made out of pipe cleaners.
Squeeze Me!
Source Institutions
In this math activity, learners guess a secret number between 1 and 100 in a three-player game.
Drops on a Penny
Source Institutions
In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.
Magic Turtle Squares
Source Institutions
In this math activity, learners create a magic turtle where all the rows, columns and diagonals add up to fifteen.
Pennies for Pits
Source Institutions
In this math lesson, learners use fruit to learn about proportions and percentages. Learners compare the weights of the edible and non-edible portions of fruit.
Equal Sharing Game
Source Institutions
In this activity, learners are introduced to division and fractions as they share snacks with a group of friends.
Light as Air
Source Institutions
In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.
Shake It Up!
Source Institutions
Learners drop a magnet through a coil of wire to create electric current in a circuit. LEDs in the circuit allow learners to detect the direction of current flow.
A Penny Saved is a Penny Heard
Source Institutions
In this activity (11th activity on the page), learners use pennies to test their hearing acuity.
Make Your Own Barometer
Source Institutions
In this weather activity (page 10 of the PDF), learners will demonstrate the changes in atmospheric pressure by constructing their own barometer.
Drop IT!: Depth Perception
Source Institutions
These two activities (4th on the page) demonstrate the importance of two eyes in judging depth.
Ready to Observe: Enhance Your Telescope Experience
Source Institutions
This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.
Filtering
Source Institutions
Make a quick and easy filter from household materials. A filter will catch any solids suspended in a liquid and filter them out. By using a filter, learners can discover amazing things.
Seeing in the Dark
Source Institutions
In this activity (17th on the page), learners investigate why you cannot see colors in dim light.
Accommodating Accommodation
Source Institutions
In this demonstration (18th on the page), learners conduct a simple test to explore how the cornea refracts light, which is further bent by the eye lens through a process known as accommodation.
Shifting Backgrounds, Shifting Images
Source Institutions
In this quick activity/demonstration (5th on the page), learners explore depth perception.
Hunger Signals
Source Institutions
This game explores the different reasons we choose to eat, and helps us be aware of when our body needs food and when it does not.
Cleaning Air with Balloons
Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.
