Hoop Glider
Source Institutions
In this activity, learners engineer a flying glider using paper hoops and a drinking straw.

Crazy Shapes
Source Institutions
In this activity, learners cut a shape into two equal sized pieces and use their knowledge of geometry and space to prove that the two parts are equal.

Sink or Float
Source Institutions
In this activity, learners will make predictions and experiment with different objects to see if they sink or float.

Rubberband Rockets
Source Institutions
This fun and simple activity is a rubberband rocket design challenge! Learners will explore how tail fins can help to stabilize a flying object, while also exploring potential and kinetic energy.

Scytale Messages
Source Institutions
In this activity, learners use a soda can to decode a secret message. Learners wrap scytale (pronounced ski-tally) code around a can and challenge friends to see if they can crack the codes.

Mountain Rescue Mission
Source Institutions
In this math activity, learners play a game that helps reinforce learners' understanding of the coordinate system.

Spinning Your (Color) Wheels
Source Institutions
In this optics activity, learners use everyday materials to make a color wheel. When learners spin the wheel like a top, they will be surprised to see all the colors mixing together to appear white.

Subtracta's Dog
Source Institutions
In this math activity related to volume, learners use problem solving skills to calculate and build a model house for Minus the dog.

Supernova Star Maps
Source Institutions
This fun astronomy activity allows learners to experience finding stars in the night sky that will eventually go supernova. This activity is perfect for a star party outdoors.

Family Traits and Traditions
Source Institutions
In this activity, learners play a matching game with their families to discover common inherited traits and traditions. Learners distinguish between inherited traits and learned traditions.

All Things Being Equal
Source Institutions
In this game, learners strategize to win the most cards by building number equations. Learners practice operations (addition, subtraction, multiplication, and division) to construct their equations.

Fair Spinners
Source Institutions
In this math game (Page 9 of the Are You Game? PDF), learners determine what makes a spinner fair or unfair. Learners first play a round with a pre-made spinner that isn't very fair.

¡Agua Cambiante!
Source Institutions
En esta actividad, los aprendices experimentarán con las tres fases del agua. Intentarán controlar la rapidez de los cambios de estado al manipular la temperatura y la presión del agua, hielo, y gas.

What Can You Make of It?
Source Institutions
In this activity (located on page 2 of PDF), learners explore alternative uses of a simple paper cup, dubbed a "mystery item." Learners act as detectives and explore the properties and functions of th

Feeling Pressured
Source Institutions
In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.
Mix and Match
Source Institutions
In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

Learn About Measurements Using a Homemade Scale
Source Institutions
In this activity, caregivers and young learners work together to make a scale from household materials to compare different weights--an essential principle in early math.

Stride Ruler
Source Institutions
In this activity, learners use their feet to estimate distances. Learners calculate the distance of one step in centimeters by measuring 10 steps at a time to reduce measurement error.

Two Lenses in One
Source Institutions
In this activity about light, learners explore how water can refract light and change the way they see things.

Soap-Film Interference Model: Get on our wavelength!
Source Institutions
By making models of light waves with paper, learners can understand why different colors appear in bubbles.
