Science Fair Invention Ideas
For all those smart kids out there, science fair is one thing they look forward to. Not to mention the joy of winning, 'coz that sure is a good feeling, every single time. So how about some invention ideas to work on for the next science fair?
- Cardboard cylinder (paper towel roll would do fine)
- Clear plastic report cover
- Black Construction Paper
- Plastic wrap & Waxed paper
- Clear tape
- Rubber band
- Ruler
- Scissors
- Glue
- Craft paint
- Markers or pens
- Glitter
- Sequins or colored beads
- Begin by drawing on the plastic report cover, a rectangle of measurement 8 x 4 inches and cut it out. Once that's taken care of, draw 3 horizontal lines across the rectangle. Let them be at a distance of 1 ¼ inches from each other.
- The step to follow this would be folding the sheet into a triangle while following the lines previously drawn on the sheet. The last tiny bit of a quarter inch should be on the outer side so as to have some space to tape it up. Doing so would help keeping the triangle from coming undone.
- After all the cutting and taping has been done, slip the plastic triangle into the cardboard roll, which should be at least 8 inches long.
- Next, you want to trace a circle on the construction paper, poke a hole into it, and with the help of some sticky tape, attach it to one end of the cylindrical piece of cardboard.
- On the open end of the cardboard roll, place some plastic wrap and push it down a little so as to create a little pouch which you will fill with the colored sequins and beads you gathered up for your kaleidoscope.
- Lastly, cover up this side with a square of waxed paper. Secure it with the help of a rubber band. Ensure that it is tight enough so that the beads and all that's been placed in that little pouch do not fall out.
- Cut off the excess bits of the plastic sheet and decorate the cardboard roll with either pretty, colorful wrapping paper, or even glitter and any other craft item.
- Various sized foam balls (to make the planets)
- Acrylic paints
- Wire
- Tin plate
- Cardboard
- Glue
- Image of the Solar System (for reference)
- The first step to recreating the solar system would be referring to its image and choosing allotting the right sized ball to each planet.
- The next step you'd want to move on with is painting the "planets" the right colors. E.g. Red for Mars, yellow for the Sun, etc.
- After you're done painting, you can move on to placing the planets appropriately. They should be placed according to their distance from the sun.
- Once you've gone ahead with all these details, you can proceed with getting the exact look of every planet. E.g. The ring for Saturn, which can be made with some cardboard.
- Following this, cut up the wire into the required number or pieces. You should have one piece for every planet. After the wires have been sorted out, pierce them through the foam balls and twist the ends so as to secure them.
- By now you should be done with the part that involves arranging the planets, therefore, it is time to fix this to the tin plate so that the wires can be suspended. Using a Swiss army knife, make holes in the tin plate, and begin by suspending the sun first. Doing so will give you an idea regarding the distance for the other planets. Keep up with placing every planet in the same method and you'll be done in no time. Your solar system is ready for display.
