Science Fair Ideas on Popcorn Projects

Popcorn is one many peoples favorite snacks. Bringing it into the science fair is a great idea for a project. You can show off some ingenuity and bribe the judges with delicious treats! There are nearly an infinite number of experiments with popcorn. A few of them are listed below.

Please Remember popcorn is just heated corn. Handle with care right after cooking

Almost all popcorn experiments give us one of two things; a better taste, or more popcorn. Taste can be a matter of preference. Here are two experiments that get us more popcorn, faster.

1) Which Brand leaves the fewest unpopped kernels. Choose 3 different brands of popcorn. Count out 3 groups of 100 kernels for each brand, a total of 900 kernels. Pop them in batches of 100. Count how many kernels are left by each brand. Repeat this 3 times for each brand. Create a chart showing your results. You could also do a break down on the cost per popped kernel. Did the most expensive brand produce the most popcorn?

2) Which brand of popcorn pops the fastest No one wants to wait for their popcorn. Win the judges over by letting them know which brands of popcorn will get to them the fastest. Choose 3 different brands of popcorn. Count out 3 groups of 100 kernels for each brand, a total of 900 kernels. Pop them in batches of 100, timing them. (The popping will go on for a while once the cooking process is done. Determine a time frame between pops that qualifies as "done")

Now you know which brand pops up the fastest. Consider looking at what other variables affect the time. What happens if you freeze the kernels? How about if you refrigerate them? Does your elevation play a role.

Third Grade Science Fair Projects

Primary children are the best age group for a teacher to handle. They are small and curious to know and learn a lot. They are still simple, loving and obedient. If the teacher makes her class interesting by giving them third grade science fair projects, they understand very well and the concept becomes crystal clear in their minds.

A third grade science fair project for body parts - Make them place their palm and fingers on a piece of thick paper and trace the outline of all the fingers, the children can color the same, they can label the names of the different fingers and some children are innovative, they even decorate the ring finger by drawing a ring and paste shiny beads to depict a ring, some of them color the nails with nail polish.

Houses for human beings made with thick card board, huts with dried leaves, nest with twigs, cotton etc. The teacher can teach how the house protects us from heat, cold, rain, enemies etc.

How to keep the house clean can be an extension of the previous topic. The children should be taught to put waste paper or any other waste item in the dust bin. Make a dustbin without spending money with the concept of Handwork out of Waste.

Animals, birds and their young ones -- cut pictures of big animals with their young one and make a third grade science fair project or a scrap book.

Plants need air, sunlight, and water to grow. Take two plants and make them grow in different pots - one pot is placed outside whereas the other pot inside a cardboard box. Cut a small hole in any one side so that the sunlight can come through that hole. Observe after few days.

Does the amount of fertilizers given to a plant affect the growth? Take three plants, first one give only water, for the second one water plus little fertilizer and the third one water plus more of fertilizer, watch the plants, you will be surprised the one with only water is the best, so dont give too much of fertilizer to the young plant, once in a while one can give little bit.

Different kinds of soil can be made in small transparent pouches and pasted in the main chart.

Food, balanced diet can be done in a pyramid form, so that the children know which food is more important for the body. Eating healthy food and being healthy can be depicted as ladders, and the diseases one can get can be depicted as snakes and make a Snakes and Ladder project. The third grade science fair projects are easy to make, easy to explain and easy to understand for the children. Once a child makes or sees a third grade science fair project, he/she will never forget the scientific concept they learned from it.
