Homemade Science Lab « The Kitchen Pantry Scientist Homemade science kits are fantastic, inexpensive holiday or birthday gifts. In addition, they’re great places to store loose science items you might already have around the house, like magnets or magnifying glasses. I’ll list how much some of the ingredients/stuff cost me at Target. In a single shopping trip, it’s easy to fill a plastic bin with enough supplies to do a number of science experiments (with a few last-minute additions from around the kitchen, like dish soap and milk.) The other morning, I talked about making your own science kit on Kare11 Sunrise. Pair your kit up with KidScience app for iPhones and iPods, and watch your kid turn your kitchen table into a science lab! I’ll list some “ingredients” for science kits and link directly to the experiments in blue (just click on the experiment name.) Safety goggles, petri dishes,magnets, plastic test tubes, eyedroppers, magnifying glasses, plastic beakers and graduated cylinders are great additions to any kit!
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. Let's look at the forces acting on that soccer ball before you kicked it. If there is more than one force acting on an object, the forces can be added up if they act in the same direction, or subtracted if they act in opposition. There is one totally important formula when it comes to forces, F = ma. Or search the sites for a specific topic. SimScientists 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. But motion is so much more. Motion is important to our lives and impacts so many things that we do. What is Force? Force is just a fancy word for pushing or pulling. These two forces act at a distance and do not require direct contact between the objects to function. See D4K's site on Gravity. Magnetism produces a force that can either pull opposite ends of two magnets together or push the matching ends apart. Types Of Contact Forces There are 6 kinds of forces which act on objects when they come into contact with one another. Let's investigate how these forces can be seen in our lives. Normal Force A book resting on a table has the force of gravity pulling it toward the Earth. Applied Force Frictional Force Tension Force Spring Force Resisting Forces What is Inertia?
Backyard Brains 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. Many people still believe this, and casual observation of everyday phenomena often does tend to confirm this view. If you drop a brick and a feather at the same time the brick will probably hit the ground first. Galileo’s discovery is important in understanding how parachutes work. Click on the image to the left to try Galileo’s experiment for yourself. Find out more about Galileo Galilei. Sea and Sky - Explore the Oceans Below and the Universe Above
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. This great educational online tool offers an interactive way for kids to play a roller coaster game, and learn while doing it. Finally, some fun online education kids! Due to some great feedback, we have decided to put back the original coaster AND also created a different version of this new coaster which keeps the coaster locked to the track.
