Model Well
Source Institutions
In this quick activity about pollutants and groundwater (page 2 of PDF under Water Clean-up Activity), learners build a model well with a toilet paper tube.
Toothpick Patterns
Source Institutions
In this math activity, learners make toothpick designs by following simple patterns.
Tip Topper
Source Institutions
In this math activity, learners role-play as wait staff at the Kidtropolis Diner. It's the end of the night and it's time for the staff to collect their tips.

Hot Spoons
Source Institutions
In this physics activity (page 2 of the PDF), learners will explore the concept of thermal conductivity and learn the differences between high and low thermal conductivity.

An Object in Motion
Source Institutions
In this physics activity (page nine of the pdf), learners use balloons to explore how a rocket works. It is suggested they also work to see how they can alter the velocity of the rocket.

Peripheral Vision
Source Institutions
In this optics activity, learners conduct an experiment to explore peripheral vision. Learners collect data about their ability to see shapes, colors, or letters using their peripheral vision.

Moving Molecules!
Source Institutions
In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw

Magnification vs. Resolution: Can you see the flag on the Moon?
Source Institutions
This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.

The Gator Pie Game
Source Institutions
In this activity, learners explore fractions as they help gators share pies.
Frustrations with Fractions
Source Institutions
In this math activity, learners make a set of fraction cards to play a game that will help relieve their fraction frustrations.

Paper Airplane Contest
Source Institutions
In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.

Race to the Top
Source Institutions
In this math game (Page 6 of the Are You Game? PDF), learners examine the probability of rolling sums from 0 to 12 with two dice. The first player to reach the finish line is the winner.

Paper Bridge
Source Institutions
In this engineering activity, challenge learners to construct a paper bridge that can support 100 pennies.

Cooling the Mummy's Tomb
Source Institutions
In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.

What Causes Pressure?
Source Institutions
In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

From Gas to Liquid to Solid
Source Institutions
What causes frost to form on the outside of a cold container? In this activity, learners discover that liquid water can change states and freeze to become ice.

¡Espirales de Colores!
Source Institutions
En esta actividad sobre la densidad de los líquidos, los participantes ven si las gotas de colorante se hunden en diferentes soluciones de agua.
Is It Possible: Estimating Measurement
Source Institutions
In this activity, learners will decide together on a question about how far, long or high the group could reach together.

Polar Bear Glove
Source Institutions
In this activity, learners will explore how animal in cold areas stay warm.

Gravity-Defying Water
Source Institutions
In this activity, learners explore gravity and air pressure as they experiment with holding a glass full of water upside down, without spilling it, using a simple piece of cardstock.
