Science Fair Projects for Kids in the 6th Grade

My wife and I were judges of science fair projects when all of our “now-grown” sons were in the sixth grade. Perhaps you are thinking that we both have doctorates in science; you would be wrong. We were the last hope of a school where getting a parent to volunteer was akin to growing money on trees.

6th grade science fair projects are fun. The students are just old enough to have some difficulty involved with their concept but, their projects are not so difficult that a person like me can’t keep up.

The first 6th grade science fair project I remember working on was a water project that involved a paper boat we built and then pasted to the rear of the boat ersatz fins. Then, we changed the texture and activity if the water (designed to show water movement) by adding dish soap. This created bubbles that propelled the boat to the end of the waterway; this also illustrated that in short distances, water movement continued until it was stopped by a stationary object; even if the waves weren’t visible. We had a lot of fun with this project.

The next 6th grade science fair project I was criticized for. I wanted to show that paper; typically a combustible material could resist fire. In college, many years ago, we were allowed to smoke in class (along with the teacher). As a result of this we were taught how to make a paper ashtray by triple-folding a piece of notebook paper and then folding the edge of all three folds on all four sides. A cigarette could be extinguished without incident or burning odor and resisted direct attempts at combustion.

My son’s work on this illustration on his 6th grade science fair project showed that by increasing cell density (the threefold bottom) and decreasing the available oxygen typically flammable materials could be altered.

One of the most difficult experiments we performed for a 6th grade science fair project involved a frog and crickets. The frog was placed in an aquarium with water and dirt; in essence we created a pond environment. We freed about six crickets. My son would watch the frog for hours at a time. The frog would remain perfectly still even when the crickets came close. However, at certain times of the day the frog seemed to be more aggressive in capturing a cricket. Ultimately it seemed the frog’s activity could be graphed based on the time of day and last time of eating.

We were able to get a general idea of his feeding schedule when we couldn’t be by the “pond” by the remaining number of crickets. This experiment could really be spiced up if there were a way to control the temperature since frogs are cold-blooded.

Of interest to me and my son, was the frog often changed positions within the “pond” environment after capturing a cricket.

One last experiment that my youngest son performed as a 6th grade science fair project was to take a piece of celery and place it in a glass of water. At that point he added food coloring and it was fun to watch the celery absorb the coloring through its “veins”; the skin of the celery was thin enough that movement up the stalk could be monitored.

Whether it is a 6th grade science fair project or any other grade, the creativity of young people never ceases to amaze me.

Incidentally, when my wife and I judged science fair projects we had a blast; I highly recommend it.
