![]() If you are more interested in cave paintings use smooth tiles to simulate cave walls.ħ. Use smooth vellum paper (available at stationery or scrapbook stores) to simulate the paper used by medieval monks or use artist’s canvas for your testing surface. Research other fixatives used by artists throughout history.Ħ. This tempera will help the colors adhere to the paper. Mix your pigments with raw egg to reconstitute them. Keep the mixture in a small glass jar with a lid.ĥ. Steep the mixture overnight and then remove the iron. Brew some very strong tea add a few iron nails or iron filings, and a teaspoon of vinegar. Scrape the soot that accumulates on a glass candle holder when the candle is burned.Ĥ. Let it dry and scrape off the green verdigris. Try polishing a small piece of copper with steel wool and brushing with vinegar. (Image credit: AjFile (opens in new tab) Shutterstock (opens in new tab))Ģ. Some of these were very dangerous and toxic such as using arsenic or mercuric sulfide, but many are safe and interesting to recreate as a science project that can also teach you some history.įind out what materials make good pigments. Research the ways in which ancient tribes or medieval artists created the paints they used for their masterpieces. *Note that your dependent variable is the success of the pigments, how will you determine which were most successful?*ġ. 2: What materials can be used to make successful pigments? You could also try an experiment to test the effects of crowding the population. Other possible brine shrimp projects could test the effects of caffeine or other pollutants. Feed brine shrimp a few grains of yeast every other day, making sure to feed each group an equal amount. Adjust the pH slowly (abrupt changes will kill the shrimp) for each test group until the water pH is equal to the pH levels of water in different parts of the country.Ħ. Over a period of days, increase the pH of the test aquariums slowly by adding a few drops of white vinegar to the water each day. Divide the shrimp into several groups in different containers, being sure to leave a control group in the original hatchery and keeping it at a pH of 7.5.ĥ. Hypothesize about the effects of an increasingly acid environment on the animals.Ĥ. Use baking soda and a pH meter or litmus paper to adjust the pH of the hatchery to about 7.5.ģ. Shrimp should be hatched in a saltwater solution (1 teaspoon non-iodized or sea salt per cup of distilled water). Hatch some brine shrimp eggs (obtained from a science supply website or catalog) in a glass container. (Image credit: Peter Baxter (opens in new tab) Shutterstock (opens in new tab))Ģ. If you still need some help, here are some ideas for good science fair projects at the high school level.īrine shrimp eggs can be obtained from a science supply website or catalog. Stumped for ideas? First, review our guide on how to choose a science fair project. Define any specialized terms used in the experiment and show any mathematical formulas that you had to use.īibliography and References Science fair project ideas You will include a history of similar experiments or inventions and their real-world applications. Research paper: This is usually a 2-3 page paper on a topic related to your experiment. It often includes experiment in different stages as well. Results: This is where you document each phase of the experiment. It must be very detailed and include accurate measurements of materials needed for each step. Procedure: This is a step-by-step set of instructions for the experiment. Materials list: All the equipment and resources needed to do the experiment. “ If soil type affects erosion rates, then sandy soils will erode faster than clay soils.” It should be stated in an “If/Then” format. ![]() This prediction must be based on some research, prior knowledge or observations. Hypothesis: This is a prediction of what you think will happen in the experiment. Students often include ideas about why the experiment is important and how the information you learn could benefit others. It describes why you are interested in the topic that you chose and what you think you will learn. Purpose: This is a statement describing what it is you want to find out by doing the experiment.
