Balloon Screamer

Balloon Screamer
In this science experiment we will explore sound, the laws of inertia, and centripetal force. In the process we will make some really cool sounds and create a balloon that screams! Your friends will love it and your family will hate it.

Color Changing UV Beads

Color Changing UV Beads
In this science experiment we will explore ultraviolet radiation from the sun. In the process we can make some cool UV bead bracelets and conduct experiments to see which sun screen works the best to protect us from the suns invisible radiation that causes sunburns!

Vanishing Water Balls

Vanishing Water Balls
In this science experiment we will explore super absorbent polymers and light refraction. In the process we will make some really cool polymer water balls that appear magically when scooped out of water and simply vanish when we drop them back into the water.

Making Oobleck And Glurch

Making Non_Newtonian Fluid Oobleck Glop 
In this science experiment we will make Oobleck and Glurch while learning about Solids and Liquids.

A great way to teach early grade schoolers about solids and liquids is with Oobleck and Glurch.
Oobleck is a Non-Neutonian fluid. This means that when a small amount of force is used, it acts like
a liquid, but when more force is applied, it acts like a solid. For instance, one can slowly put a spoon
in Oobleck, but it is impossible to stir it quickly. Another fun activity (though potentially messy!) is to
pour a little Oobleck in the palm of your hand and watch it puddle like a liquid. Now make a fist and
quickly open your hand. The Oobleck will have formed a hard ball from the pressure of your fist; but when the pressure is release, it will seem to "melt" into a liquid again.

Sound Hose

Sound Hose
In this science experiment we will explore sound waves, the Bernoulli Effect, Vortices and the movement of air molecules. In the process we will make some really cool sounds and create a music instrument that changes pitch as you twirl it! Your friends will love it and your family will hate

it.

Model Rocket

Model Rocket

In this science experiment we will explore Newton's third law which states for every reaction there is an equal and opposite reaction. We will also learn about thrust, lift and drag. In the process we will launch a model rocket up about 1500 feet in the air.

Balloon Rocket

Balloon Rocket
In this science experiment we will explore Newton's third law which states for every reaction there is an equal and opposite reaction. In the process we will make some really cool sounds and launch balloon rockets up about 40 feet in the air.
