Lemelson Center’s Invention at Play: Invention Playhouse

Lemelson Center’s Invention at Play: Invention Playhouse
Exploration/Tinkering Exploratory play is about asking questions: “What happens when I do this?” “What if I did it this way?” Experimenting with materials and pushing their limits encourages us to consider a wide range of possibilities when problem-solving. Playing around with objects and ideas helps us see that there may be more than one solution. Some inventors have a goal in mind and work persistently toward it.

Roller Coaster Game Welcome to the death defying Funderstanding Roller Coaster! This simulator is designed for people who want to design their own thrilling coaster and educators who want to use a cool activity to simulate the application of physics by using an exciting interactive tool and access to a wonderful reference source. It is your mission to become a roller coaster designer so that you can achieve maximum thrills and chills without crashing or flying off the track (unless that’s how you like your coaster to work!). If you accept this mission you must decide on a number of factors. You are responsible for setting the controls for the height of hill #1, hill #2, the size of the loop, the initial speed of the coaster, its mass, the gravity at work and the amount of friction on the track.

Galileo Drops the Ball - Virtual Experiment In around 1590 Galileo Galilei (1564-1642) climbed up the Leaning Tower of Pisa and dropped some balls to the ground. Two balls of different masses, but of similar shape and density that were released together hit the ground at the same time. Until then it was commonly believed that heavy things fall faster than light things. Force and Motion Facts Motion makes the world go 'round. Motion makes the moon go 'round too. In fact, motion makes lots of things go. When we think of motion we often think of cars, bicycles, kids running, basketballs bouncing and airplanes flying. Great Teaching Ideas lesson & unit viewer Communication Arts 1. Speaking and writing standard English (including grammar, usage, punctuation, spelling, ...)

Motion: Forces Forces are a big part of physics. Physicists devote a lot of time to the study of forces that are found everywhere in the universe. The forces could be big, such as the pull of a star on a planet. The forces could also be very small, such as the pull of a nucleus on an electron. Forces are acting everywhere in the universe at all times. Amusement Park Physics Design a Roller Coaster Try your hand at designing your own roller coaster. You will be building a conceptual coaster using the physics concepts that are used to design real coasters. You won't need to compute any formulas. You will decide the following - the height of the first hill, the shape of the first hill, the exit path, the height of the second hill, and the loop. Tremors of the Big Bang: First direct evidence of cosmic inflation Almost 14 billion years ago, the universe we inhabit burst into existence in an extraordinary event that initiated the Big Bang. In the first fleeting fraction of a second, the universe expanded exponentially, stretching far beyond the view of our best telescopes. All this, of course, was just theory. Researchers from the BICEP2 collaboration today announced the first direct evidence for this cosmic inflation. Their data also represent the first images of gravitational waves, or ripples in space-time.

Science Gal: Creating Catapults This is another engaging after school activity that we used in our Force and Motion science club. It would be easy to add to your existing curriculum; especially if you teach the FOSS Variables kit. In the Variables Kit, there are four problems for students to explore and test variable - pendulums, penny boats, planes and flippers. Flippers are really catapults that you can change the height of the object's trajectory path by changing the length of the flipper. Another great FREE game from FOSS is the Blasto Game. FEI Torilis Arensis Courtesy of Pat Kysar Product: SEMTorilis arvensis is commonly known as Spreading Hedge Parsley. The plants grow up to 3 feet in height with tiny flowers clustered in small flat-topped umbels. T. arvensis fruit (schizocarp) measure 4-6mm and usually hold 2-4 individual seeds (mericarps).
