Two Interesting Science Fair Projects That Make Great Demonstrations
Although demonstrations are interesting science fair projects, they do not always have to used in a science fair. They often work best in the classroom to show one point the teacher wants to make as part of their lesson. Sometimes each kid will be asked to demonstrate a couple times a year.
What makes a successful demonstration?
- A successful demonstration needs to grab attention and have some pizzazz. At the same time it needs to demonstrate a real science concept.
- No matter what, the project needs to follow the directions and show scientific curiosity. Doing a demonstration just for the pizzaz and not to demonstrate some scientific principal is a bad idea.
- They really need to be quick and easy science fair projects or else they just get too complicated
- A well practiced demo contributes more to the success sometimes than the experiment! They should practice at home many many times!
Here are two examples of successful and interesting science fair projects that that work really well as a demonstration.
Show how yeast gives off gas.
Put yeast in a bottle of warm water or grape juice, top it with a balloon, and watch the balloon fill up with
This is a good example of a demonstration where your actual experiment would have been more involved. You may have had five bottles with different liquids and you measured the air in the balloon at different intervals to see which one worked the best.
- Your demonstration would be with the one that worked fastest and the balloon grew the biggest, because that would be the most interesting.
Show how a chicken egg is a cell with a selectively permeable membrane.
Soak a raw egg in vinegar for a weekend. The shell will come off. Then put the egg into dark syrup and watch what happens!
It is a great example of how a project that is very simple to do, demonstrates a more complex concept.
- The preparation would take place ahead of time, but the point is to demonstrate what that happens when you put the egg in the dark liquid.
FYI: Detailed instructions for these two projects and others like these are available at through this link to: 24hourscienceprojects.
Simple Demonstrations Interesting Results
- One of the benefits of a demonstration is that it is that preparation is quick and easy.
- You have to find projects that are totally designed to for demonstrations. A whole pile of science fair projects will bore everyone to tears, and take too much time. if you use it as a demonstration.
I found this an excellent resource with outstanding ideas for interesting science fair projects that work well as demonstrations. These are kid tested and teacher approved— You will love them!
