Kids science project ideas are numerous, depending on the category of science. Experiments can be done just about everywhere, such as in your backyard, kitchen, local park, classroom, and so on. Kids are naturally curious and like to experiment to see how things work. There are many ideas for science projects, but it is important to pick one that suits your child's age so they can get as much enjoyment out of it as possible and be proud of their results.
One fun kids science project is to see what sort of items will float or sink in a water, vinegar, and baking soda mixture. You can do this kids science project with your kids right in your own kitchen. All you need is a clear plastic or glass container, water, vinegar, baking soda, food coloring, and some items like raisins, rice, dried fruit, and broken bits of spaghetti to test whether they will float or sink.
The first thing you will need to do is fill the container with three parts water and one part vinegar. Be sure to leave some room at the top of the container. Very slowly, add one teaspoon of baking soda. If you add too much at one time it will bubble over the top. You might want to keep a towel handy. Once the bubbles have settled down, slowly add another teaspoon of baking soda. When the bubbles settle down after the second teaspoon, add a few drops of food coloring. Next comes the fun part. Get the kids to gather some items to drop in the mixture and guess which will float and which will sink. Have them write down their hypothesis. Drop in a few of the first item and see what happens, then continue with the other items. Record your results.
