The field of quantum mechanics all fundamental forces are carried by particles. For instance, light is made up of massless particles called photons that carry the electromagnetic force. Likewise, the graviton is the theoretical particle that would carry the force of gravity. Scientists have yet to detect gravitons, which are tricky to find because they interact so weakly with matter.

The speed of gravity is taken to be exactly equal to the speed of light. But is that necessarily true? Here's how we know.

Love this interactive science site!  My 3rd and 6th grader have learned about everything from the parts of a flower, to electrical currents and melting points.  The games are really engaging; this has been a great supplement to our homeschooling.

One of my favorite parts in the season finale of Gravity Falls. I'm really upset about the last episodes, I don't want the fun to end... T^T

Again, easily extended for older children by adding two ramps so that comparisons can be made, applying cloth to the surface, then vaseline, to see how those affect rolling speed, etc.

When you plummet on Tower of Terror, you are not freefalling.  The vehicles lock onto platforms in the drop shafts connected by cable to two enormous motors which are used to move the platform up and down at rapid speeds--faster than gravity alone.  You'll hit top speed of 39 mph. Place a penny in your hand.  When you drop, it will float because it is only falling at the speed of gravity.
