Gravity Waves Gravity waves are distortions in the fabric of space-time predicted by Albert Einstein's theory of general relativity. The gravitational waves travel at the speed of light, but they are so weak that scientists expect to detect only those created during colossal cosmic events, such as black hole mergers like the one shown above. LIGO and LISA are two detectors designed to spot the elusive waves.
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.
FREE!!! Engage your students with this Around the Room Force and Motion Circuit Activity. This activity contains 21 questions and answers.
