Have you ever wondered why biological siblings look so much alike? Why do they often share physical traits, such as hair color or eye color? It all has to do with their genes. Genes are passed on from parents to their offspring. This means that you share some of the same genes with your biological parents and siblings! In this activity, you will use an alien model to demonstrate how genes or physical traits are passed on from parents to their offspring. How similar will your alien siblings look? Read more

Which Orange Juice Has the Most Vitamin C?

Science Fair Project Idea

Scientific Method

Which type of orange juice has the most vitamin C? In this science project, you will learn how to measure the amount of vitamin C in a solution using an iodine titration method. You will compare the amount of vitamin C in three different types of orange juice: homemade, premium not-from-concentrate, and orange juice made from frozen concentrate. Which do you think will have the most vitamin C? Read more

Wildfire Simulator

Science Fair Project Idea

Scientific Method

Wildfires can devastate communities, destroying homes and creating smoke that can affect air quality over huge areas. A wildfire could start from a natural cause like a lightning strike, or humans being careless with cigarette butts or campfires. What if you could predict how a wildfire will spread to help give people an advanced warning to get out of harm's way? Can forest management techniques like controlled burns—intentionally setting smaller, more controlled fires—help reduce… Read more

Can Peppermint Improve Reaction Times?

Science Fair Project Idea

Scientific Method

Did you know that some teachers give their students a peppermint candy on state testing days? Is it to give the kids sweet-smelling breath? Or are the teachers hoping for something more on the important testing day? In this human biology science fair project, you'll explore whether or not peppermint influences scores on different types of tests. Read more

Crime Scene Chemistry: The Kastle-Meyer Test for Blood

Science Fair Project Idea

Scientific Method

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… Read more

Extracting Onion DNA

Science Fair Project Idea

Scientific Method

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. Read more

Do you think plants can grow without soil? If you've tried growing vegetables, you probably planted the seeds or seedlings in soil. Soil gives the plants the nutrients they need to grow. However, plants can grow without soil, too, using a process called hydroponics. In this activity, you will transform a bottle into a mini-garden that needs only light, air, and nutrient-rich water to grow! Read more
