Try this amazing tool for learning the concepts of motion, forces, electricity, magnetism, light, and so much more. You can bounce and slide your way through the developed levels or get creative and make your own level.
Try out this activity by moving the boat around the water by changing the magnitude and direction of the boat's speed (blue vector) or the magnitude and direction of the water current (red vector). Try to land the boat on the island without hitting the walls,
In this activity, you relate gravitational force to masses of objects and distance between objects. In addition, you learn about Newton's third law for gravitational forces. You can visualize the gravitational force that two objects exert on each other.
In 2012, scientists at CERN discovered evidence of the Higgs boson, one of two types of fundamental particles and a game-changer in the field of particle physics, proving how particles gain mass. This animated video explains the exciting implications of the Higgs boson.
This 9-minute video explains the cyclical phenomena at work in the universe. Learn about the subtle changes in the sky as the Earth circles the sun, following along the ecliptic. Learn how the tilt of the Earth's axis has a profound effect on the planet by creating the seasons.
Explore how our understanding of planetary orbits has changed throughout history in this video about Kepler's laws of planetary motion. Animations show the geocentric model of the solar system and the heliocentric model.
This video explains how the shape of the Earth's orbit around the Sun and the Earth's tilt on its axis affect the amount of sunlight we get in winter and summer. Learn about Kepler's discoveries and how they explain the seasons.
This video asks the question: if you placed a camera at a fixed position, took a picture of the sky at the same time every day for an entire year, and overlaid all of the photos on top of each other, what would the sun look like? It makes a ‘figure 8’ pattern, known as the Sun’s analemma.
