Remember going to the doctor and getting vaccine shots? It is no fun getting poked with a needle, but fortunately, a vaccine helps our immune system to develop protection against a serious illness for years to come. But what about the flu vaccine? How come there is a new one every year? This science fair project will show you why.
Do you know someone who has an autoimmune disease? Autoimmune diseases are fairly common, affecting more than 23.5 million people in the United States, which is about 1 in 13 people! You may have heard of some of them, such as diabetes (type 1), rheumatoid arthritis, and celiac disease. Many autoimmune diseases are poorly understood, but they all have one thing in common: they happen because a person's immune system (which normally fights off germs to keep the person healthy) attacks the…
Police detectives use various scientific tools to analyze evidence at a crime scene. One of the classic tools is the Kastle-Meyer test for the presence of blood. This test is inexpensive, easy to perform, and provides quick results. The test provides evidence if red spots found at a crime scene are actually blood. But the investigator needs to be careful, since other substances can also give a positive result. In this crime scene chemistry science project, you will learn how to perform the…
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!
Do you love the look and feel of leather? Many luxury items like handbags, belts, wallets, and coats are made from leather. What if you could make your own vegan leather in a few weeks? Could it be a greener, more sustainable option than cowhide leather? In this science project, you will grow your own vegan leather from kombucha and see how different growing conditions affect the resulting leather.
Did you know that cosmetics companies employ teams of specialized scientists to develop and test each new line of makeup, perfume, lotion, or soap? This science project lets you be the cosmetics scientist. You will create your own lip balm right in your kitchen using a short list of ingredients, then test it, and follow up with some creative cosmetics science of your own!
Can you imagine clothing, handbags, or shoes made from seaweed or spider silk? To become more sustainable, the textile industry is looking for ways to develop more eco-friendly fabrics. Biofabrics derived from living organisms such as seaweed or bacteria have been proposed as a potential alternative to conventional fibers. In this science project, you will make several biofabrics from alginate (seaweed) and conduct tests to find out which one is most suitable as a textile replacement.
Many foods, such as fresh fruits, vegetables, or eggs, are packaged in plastic to protect them from damage during handling and transport. But is plastic the best choice? What if a more sustainable and biodegradable material could replace it? Researchers have begun exploring hydrogels—squishy materials that can hold a lot of water—as alternative packaging materials. In this science project, you will make your own hydrogels from gelatin and cornstarch and investigate what ratio of…
Imagine if instead of spooning up a bowl of soup, a container of yogurt, or a cup of pudding you could just pick up and pop in your mouth a round, mess-free, ball-like blob of one of those. It might feel like snacking rather than eating a meal! In this food science project you can try exactly that. The simple step-by-step directions will lead you through trying a fun cooking technique called reverse spherification to turn yogurt into semi-solid balls, which are called "raviolis." How do you…
Have you ever wondered why some liquids mix together easily, like when you mix different juices to make a fruit punch, while others do not mix at all, like oil and water? What happens to liquids when they are mixed depends on their mixing behavior. Some liquids blend, whereas others form separate layers. If you do it right, you can even stack liquids on top of each other just like solid objects! Want to see for yourself? In this science project, you will investigate the mixing behavior of…
