An experienced chemistry professor used to say that it took about one explosion per week to maintain college students' attention in chemistry lectures. At that rate, we'd get in pretty big trouble with a lot of parents and teachers! Don't worry, our list of chemistry science and engineering projects still has lots of bubbles, fizzes, bangs, and color changes for you to explore.
Some laundry detergents have added enzymes that break down proteins, helping to remove them from the cloth fibers, and thus remove stains. You can perform a scientific test of these enzymes' stain-fighting ability. Do background research on the enzyme(s) in the detergent, and on the substances you choose for making the stains. Try to predict for which substances the enzymes will be effective. Cut a piece of light-colored cotton cloth into identical 10 cm squares. Choose different…

You've probably heard of hand prints and fingerprints, but what about a Sunprint®? To make a Sunprint, place an interesting object on a special sheet of Sunprint paper, expose it to the sun for a few minutes, immerse the paper in water, and watch as a permanent image appears! Sunprint paper can be used to make beautiful and eerie prints, using just sunlight and water. Sunlight is actually a mixture of different colors of light. In this chemistry science fair project, you will test which…

Crystals come in all different shapes and sizes. However, the purest and cleanest crystals are usually also the ones that grow to be the largest in size. In this science fair project, you will compare the size and shape of crystals grown in three different temperature conditions: room temperature, in the refrigerator, and in an ice bath. With just water and borax, a household cleaning product, you can discover the best recrystallization method for growing large, pure crystals.

Do you ever wonder how markers are made? Where do all of those colors come from? Many of the colorful dyes we use come from plants. Could you create vibrant colored natural dyes? Could you turn these dyes into art supplies? You can! In this science project, become a scientist and engineer and make your own marker using homemade plant dye!

This project requires 1 mL syringes. See the Materials and Equipment list for details. Estimated project time includes time to ship the syringes. The experiment itself will take less than one day.
In this project you'll make a liquid that will contradict your expectations. Hold it loosely in your hand and it will drip off your fingers, but grab it tightly and it will feel solid. Slap a bowl of it with a spoon, and instead of splattering, it solidifies. Do background research on colloids, and be sure you can explain the following terms: colloid, Newtonian fluid, non-Newtonian fluid, thixotropic. (For instructions on how to make it see the link listed under Exploratorium, 1998, in the…

There are three different kinds of polymers used for kitchen plastic wrap: low density polyethylene (LDPE) (e.g., Handiwrap or Glad Wrap), polyvinyl chloride (PVC) (e.g., Reynolds PVC Foodservice Wrap or Boardwalk PVC Food Wrap Film) and polyvinylidene chloride (PVdC) (note: Saran Wrap used to be made with polyvinylidene chloride, but has switched to polyethylene. You will need to search for another brand that uses PVdC if you want to test it). Which of these materials is least permeable to…

Here's a chemistry project for a beginning scientist. You'll need two 100 ml graduated cylinders, rubbing alcohol, water and liquid food dye. (You can make your own measuring cylinder from a recycled jar: tape a vertical label on the jar and carefully add water 1/4-cup at a time; mark the level on the label with each addition.) Measure 50 ml of water. Add a drop or two of food coloring and mix. In the second cylinder, measure 50 ml of rubbing alcohol. Carefully pour this…

"Plastic made from milk" —that certainly sounds like something made-up. If you agree, you may be
surprised to learn that in the early 20th century, milk was used to make many different plastic
ornaments —including jewelry for Queen Mary of England! In this chemistry science project, you can figure out the best recipe to make your own milk plastic (usually called casein plastic) and use it to make beads, ornaments, or other items.

Some chemical reactions occur explosively fast, others may occur almost imperceptibly s-l-o-w-l-y. This project explores what effect the particle size of the reactants has on the speed of a chemical reaction: production of carbon dioxide gas by an Alka-Seltzer® tablet.
