Cafe Wall Illusion
Source Institutions
In this fun and interactive online exhibit, the straight lines of a tile wall appear to curve. The learner moves the rows of tiles and changes the color of the grout to achieve the intriguing effect.
Guess My Rule
Source Institutions
In this simple game, learners start to understand how to sort and categorize objects by trying to guess the connection between three items that someone else has chosen.
Magnet Tower
Source Institutions
In this activity, learners build magnetic towers to explore the forces and properties of magnets.
Place Matters: How Sound Changes Due to Environment
Source Institutions
This is an online simulation of how sound changes due to environment. How does place--like a cave, a pier, or a forest--affect certain sounds?
FAMILY MATH on the Go
Source Institutions
This assortment of mathematical games can be played while traveling.
Heart Rate and Exercise
Source Institutions
In this activity about heart health (on page 27 of the PDF), learners measure their heart rates after a variety of physical activities and compare the results with their resting heart rates, and with
Try Growing Your Own Mold
Source Institutions
This is a hands-on activity that uses bread and household materials to grow mold. Learners collect dust from a room, wipe it on food, and contain it. One to seven days later, mold has grown.
Air Pressure
Source Institutions
In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.
Round & Round
Source Institutions
In this activity, learners make and test fly paper helicopters. Learners use templates to create paper helicopters and then take take turns flying them in the air.
The Power of Graphene
Source Institutions
This lesson focuses on graphene and its electrical properties and applications.
Exploding Baggie
Source Institutions
In this activity, young learners will experiment with a basic chemical reaction and observe what happens when gas gets trapped! Activity includes step-by-step instructions, safety notes and more.
Chirping Bird
Source Institutions
In this activity, learners build a cuica or chirping bird using straw, string, and a bottle cap. Use this activity to explore the interplay of motion and sound.
Heat Capacity: Can't Take the Heat?
Source Institutions
Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.
Fireworks in a Glass
Source Institutions
In this activity, learners use water, oil, and food coloring to observe a chemical reaction that creates a shower of colors inside of a glass.
Rocking Changes
Source Institutions
In this earth science activity, learners conduct a series of short experiments to explore how rocks change.
Family Flyers
Source Institutions
In this activity, learners work in teams to build and test paper airplanes. Learners try to fly their airplanes directly on the runway and earn points for accuracy.
Design and Build a Wind Vane
Source Institutions
In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.
Investigating Sleep
Source Institutions
In this activity about sleep rhythms (on page 25 of the PDF), learners will investigate how changing the time they go to bed impacts their own sleep patterns.
Electromagnet
Source Institutions
In this activity, learners build an electromagnet using a nail, a cork, a battery, and electrical wire. Use this activity to demonstrate how electric currents produce magnet fields.
Sounds of the Heart
Source Institutions
In this activity, learners will investigate the sounds of the heart.
