WonderHowTo Most of us have conducted an investigatory science project without even knowing it, or at least without knowing that's what it was called. Most science experiments performed, from elementary to high school students and all the way up to professional scientists, are investigatory projects.

Investigatory projects, or science projects, teach people important ideas about their world and can also be a lot of fun. Read on for some investigatory project examples your kids will love! To perform this experiment, you'll need a Bunsen burner or other heat source, some things to burn, and a diffraction grating.

You can obtain these supplies from Edmonds Scientific see the link below. As for the objects to burn, wood, salt, sugar, and various nitrate salts work magnificently. Just make sure you have a few samples of each item. Burn each chemical on a small wood stick individually and observe the color of the flame with and without the diffraction grating, which separates the flame into its component colors or spectrum.

Observe that each chemical gives off a different spectrum. This spectrum can be used to identify the chemical very accurately. Each chemical emits a different spectrum when burnt. By recording this spectrum, you can identify a chemical based on how similar its spectrum is to known spectra given off by other chemicals.

Lower a rolled-up paper towel into a glass full of water until about two centimeters of the paper towel are in the water.

Observe how the water seems to flow up the paper towel, contrary to what one would expect.

Eventually, the paper towel will become fully wet. This demonstrates capillary action, because the water has less of a cohesive force than that of the adhesive force between the towel and the water. Hence, the towel pulls water up, against gravity. This also works with a very narrow tube in place of a paper towel.

To add some color to the experiment, try putting food dyes in the water. Also, observe what happens when you put more than one type of food dye in the water.

If you use two dyes of different densities, you should observe that the paper towel eventually separates the colors based on their differing densities. This temperature is known as the magnet's Curie Point. This can be demonstrated easily with a few permanent magnets, some paperclips, and a propane torch.

The demonstration should only be done by an adult familiar with the safe use of a propane torch. First, take one of the magnets and prove that it is magnetic by using it to pick up a few paperclips. Now, use the propane torch to heat the magnet until it glows red.Banana Peelings as Dishwasher(Science Investigatory Project) Search Search.

Below is an example project that creates soap from guava leaf extract and sodium hydroxide, but there's no shortage of materials you can use to replace the guava, like coconut oil or a fat like lard, butter or even the grease from your kitchen.
