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.

Have you heard that garlic powder is supposed to inhibit the growth of bacteria? Which do you think would make a better disinfectant: a solution of garlic powder or a solution of bleach? This project shows you a straightforward way to compare the effectiveness of different disinfectants (or other antimicrobial agents), by measuring zones of inhibition on a culture plate.
In this project, you'll learn how to isolate DNA from onion cells, separating it from other cellular components in a manner that still preserves its structure and sequence. In the end, you'll have enough DNA to see with the unaided eye, and you'll be able to spool it to demonstrate its strand-like structure.

Artificial intelligence (AI) programs can now generate photorealistic pictures of people who do not exist in the real world. How can you tell if a picture is of a real person or a fake, AI-generated person? What features of the picture do people use to decide whether the face is real or AI-generated? In this project, you will explore these questions as you ask volunteers to look at both real and AI-generated pictures of human faces.
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!
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?
Do you know why enzymes are oftentimes called the workhorses of biochemistry? It's because they can speed up a wide variety of chemical reactions, and chemists and biologists use enzymes to do all kinds of jobs. In this project, pectinase, an enzyme frequently used in the food industry, will be used to extract juice from apples.

Many individuals who are blind or visually impaired use canes to navigate their surroundings, using their sense of touch to detect obstacles. What if you could create an electronic cane that emits an audible warning before coming into contact with an object? This project allows you to do just that by incorporating an ultrasonic distance sensor and a buzzer to alert the user of approaching obstacles. You can customize the cane by adding additional features or altering the design, such as using a…
Do you like solving mysteries? In this experiment, you can find out how a DNA fingerprint can help you figure out whodunit. The answer might just be in the "sequence" of events!
Ever used a pair of molecular scissors? Restriction enzymes are molecular scissors that cut DNA into pieces. Find out which enzymes will cut, and where by making a restriction map. Then you can figure out what will happen if you change the sequence of the DNA. Will the same enzymes still cut the new DNA sequence?
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…
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.
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?
