Set up your science experiment table with six stuffed teddy bears of various shapes, styles and sizes. Cut a slit in the tummy of a thin-skinned bear and place a heavy magnet inside, close to the surface. Stitch up the teddy bear. Place a few more magnets inside the teddy bear's ears and paws. Now, line your table with metal items like: batteries, paper clips, screws, coins and more. Then, invite your science fair spectators to find the "Magnet Bear" using the items on your table, for a fun, hands-on experiment. Encourage your guests to place the metal pieces all over the teddy bears' bodies until they locate the magnets.
Our many senses make for an educational science fair project. And the sense of touch is especially fascinating. For this experiment, place six large brown paper bags on your table. Fill each bag with a different stuffed animal such as: teddy bears, monkeys, giraffes, dogs, elephants and more. Invite your curious science fair visitors to test their sense of touch by guessing the animal inside each brown bag. Keep a log of which animals were the easiest and most difficult to identify.
Place both a stuffed polar bear and a grizzly bear on your science fair project table. Next, for each bear create a colorful and informative poster board containing the differences between the two. For example, polar bears eat seals and walruses while grizzly bears usually feast on berries, nuts and fish. And polar bears live in ice covered regions while grizzlies normally reside in woodlands and forests. Once you have presented your science experiment viewers with the facts, quiz them with questions pertaining to each bear.
Test the laws of gravity with stuffed teddy bears for your next science experiment. Choose several bears ranging in size from small to large. Make parachutes for the bears using household items like plastic baggies, scarves and bandannas. Tie strings onto the four corners of each parachute and attach to the bears. Drop each stuffed bear from a given height and record whether the bear floated down to the ground or experienced a crash landing.
