Inventions teach kids about their world. Children learn about physics, math and science through projects. Inventions can be done for school science fairs, or as a weekend or summer project. Not only do inventions keep kids busy, they provide opportunities for family bonding if parents and siblings help out. Kids have invented a lot of popular items. Earmuffs were invented by a 15-year-old in 1873, and an 11-year-old invented the Popsicle in 1905.
Fruit Ice Pops
Making a fruit ice pop is an easy invention for young kids. Not only do they invent something, they also create a tasty treat. The procedure involves pouring fruit juice into ice cube trays or other small ice mold, placing plastic wrap over the top and piercing the top with a toothpick or wooden stick through the middle of each ice cube. Place the concoction in the freezer and wait for the fruit ice pops to solidify.
A simple telescope can be made using a pair of reading glasses, a magnifying glass, flashlight, masking tape and wax paper. You will need a friend to help. The glasses are taped to a pole of some sort such as the leg of a table. One lens of the glasses sticks out and acts as the "objective lens" of the telescope. No tubes are used so as to allow the viewing of what happens inside a telescope. The flashlight is placed on a table 13 or more feet away from the glasses. The light is turned on and faced towards the lens. A paper is placed on the other side of the lens. The paper is slowly moved away from the lens until a small image of the flashlight appears. Your friend will need to hold the paper at this distance as you continue backing up until the image on the paper is magnified. Your friend then removes the paper and you can continue to look through the homemade telescope.
A mechanical toy can be built using a shoebox, wire coat hanger and other office supplies. The coat hanger is straightened out and two dips are bent into the wire to create a rectangular dip and bump. A straightened paper clip is then attached to each of the dips. The hanger is placed inside the shoebox with the ends sticking out the sides. The paper clips should come out of holes at the top of the shoebox. Create a crank at one end of the hanger. Tape decorations to the paper clip ends and crank away.
