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.

Wacky Physics: The Coolest Little Particles in Nature

In the next five years, scientists may find the first proof of gravitational waves — ripples in the fabric of space-time predicted by Einstein's general relativity.

This FUN force and motion unit is JAM-PACKED with engaging science experiments, learning stations, games, printables, songs/poems, an assessment, 12 colorful learning posters, coordinating vocabulary cards, and so much more! Your students will learn how push, pull, friction, gravity, and speed make things move. Six motion mission activities create the ultimate science centers and STEM experience. Your students will even use the playground to learn how push and pull works in their everyday…

Forces and Motion

Analyze data to determine if a design solution works as intended to change the speed or direction of an object with a push or a pull.

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.

Science Kids Fun Science & Technology for Kids! Quizzes, videos, experiments, games, facts and more.

Force and Motion fill-in-the-blank

This is a summary of the grade Science Unit 8 on Force and Motion in the Harcourt Series. I'm adding it to the Unit Test included in the textbook.

Ripples in spacetime are what gravitational waves are.

There Is Sound In Space, Thanks To Gravitational Waves

Why does gravity move at the speed of light? Newton thought it was instantaneous, but the story is much richer than that!

Sam Taylor Wood Anti-gravity case study, used for the illusion of floating

Sam Taylor-Wood - "Taylor-Wood's work examines the split between being and appearance, often placing her human subjects either singly or in groups, in situations where the line between interior and external sense of self is in conflict.

Why Does Gravity Move At The Speed Of Light?

The speed of gravity is taken to be exactly equal to the speed of light.

We May Finally Understand the Speed of Gravity Observations of both gravitational waves and light originating from merging neutron stars suggest that the speed of gravity is practically the speed of light. This confirms the theory of general relativity and gives us greater insight into the cosmos.

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.
