The kids love to do sink or float experiments so I decided to do another science activity related to buoyancy. If you missed it, we did a ‘corny science’ experiment using different types of corn in carbonated and still water. This time, we used various nuts and seeds and a combination of salty and plain water.
Nutty Science Experiment:
You will need:
- A combination of unsalted nuts and seeds
- two glasses
- warm water
- table salt
- spoon or knife to mix in the salt
Have your children or students arrange the nuts and seeds by size. We used almonds, peanuts, pine nuts and sesame seeds. Then, fill two glasses with warm water. Add salt to one glass and stir to dissolve as much as you can. I used 1/4 cup of salt to one cup of water. I discovered this was probably about twice as much as I needed. I suggest that you use about 1/8 of a cup to one cup of water. Have your children predict what will happen when they drop the nuts and seeds into the two types of water. Next, have your preschoolers drop one each of the same kind of nut or seed into the water and discover if the nut or seed sinks or floats in the salted vs. plain water. They can keep a simple chart or tally to see if their predictions are correct.
The kids loved dropping the nuts and seeds into the water and, for the most part, were accurate in their predictions as to what would happen with each test. They were eager to do nut and seed taste tests after the experiment. The only unsalted peanuts I could find were in the shell. They had a great time cracking open the peanut shells for a post-experiment snack. It turned out to be a nice hidden fine motor skill building activity. They made little finger puppets, at my suggestion, with the empty shells using funny voices to make their peanut shells talk. Just for fun, I also cracked open a few peanut shells, unbeknownst to them and took out the peanuts. I hid gummy fruit snacks inside the shells and had them break them open to find something other than the peanuts. I acted very surprised at their discovery. They were pretty sure I was the culprit behind the mystery nuts, but I think there was a part of them that wondered if these ‘special fruity nuts’ really existed. Have you done buoyancy experiments with your children or students? Have you tried any activities with the nut and seed theme? I would love to hear from you in the comments.
