Have you ever wondered how scientists get a sample of DNA from a plant, animal, or other organism? All living organisms have DNA. DNA, which is short for deoxyribonucleic acid, is the blueprint for almost everything that happens inside the cells of an organism — overall, it tells the organism how to develop and function. DNA is so important that it can be found in nearly every cell of a living organism. In this activity, you will make your own DNA extraction kit from household… Read more
Do-It-Yourself DNA
Science Fair Project Idea
Scientific Method
All living things have DNA inside their cells. How do scientists extract the DNA from cells in order to study it? In this science experiment you can make your own DNA extraction kit from household chemicals and use it to extract DNA from strawberries. Read more

Have you ever wondered what whipped cream, jelly, and milk have in common? Aside from all being tasty, they are also all made up of tiny particles that are dispersed, or distributed, in water. This type of mixture is called a heterogeneous mixture. Some of these have very interesting physical properties, such as acting like a solid and a liquid at the same time! In this activity, you will get to create Oobleck, a mixture that is made using cornstarch and water, and then explore these… Read more
Liver Stinks!
Science Fair Project Idea
Scientific Method
Sometimes science can be really messy or use pretty disgusting ingredients. That is what it takes to understand how the world works, even if the experiment isn't pretty. Do you like chemical reactions that stink and ooze foamy bubbles? Do you think it sounds fun to make a super gross liver smoothie? Then this is the experiment for you! Read more
Mag-nificent Breakfast Cereal
Science Fair Project Idea
Scientific Method
How much iron is in your cereal? In this experiment, you will devise a way of testing foods for supplemental iron additives. Then you will use your design to test different breakfast cereals to see how much iron they contain. Which brand of cereal will have the most iron in it? Read more
Separating Glitter with a Homemade Centrifuge
Science Fair Project Idea
Scientific Method
It is fun to shake up a snow globe and watch the "snow" slowly fall. You can imagine that if the snow fell down very quickly it would be disappointing. But there are times when scientists in a laboratory want this to happen. Scientists use samples that have liquid mixed with small, solid pieces (like the inside of a snow globe), and they need all of the solid pieces in a clump, separated from the liquid. Instead of waiting for the pieces to slowly fall out of the liquid, scientists speed up… Read more
A Magnetic Primer Designer
Science Fair Project Idea
Scientific Method
How do scientists "copy" DNA? They use a process called the Polymerase Chain Reaction, or PCR. The key to making this process work is having a short piece of DNA, called a primer, that will stick to the larger piece of DNA you want to copy, called a template. In this science project, you will test how the number of matches and mismatches in a primer will affect its ability to stick, or anneal, to the DNA template during PCR. Read more
Separating Butter with a Salad Spinner Centrifuge
Science Fair Project Idea
Scientific Method
Imagine that you could make an important piece of laboratory equipment in your kitchen. With this science project idea, you can! You will create your own centrifuge out of a salad spinner and some putty. In science labs, centrifuges are used to separate different liquids and/or solids from each other. You can load your homemade centrifuge with samples and see how they separate. What do you think happens to melted butter in a centrifuge? Read more
