Effects of Exercise: Changes in Carbon Dioxide Output

Science Fair Project Idea

Scientific Method

You might know that your body needs oxygen to keep going, and that you breathe out carbon dioxide as waste. What happens when you exercise? You have probably noticed that you breathe faster, and your heart beats faster. What triggers your body to respond in this way? How does it "rev up" to keep your muscles going? In this project, you will get a peek into the fascinating science of exercise physiology and find out—with the help of a color changing reaction. Read more

Combine Newton's third law of motion with engineering design in one fun lesson! Your students will learn about equal and opposite reaction forces as they design and build a bumper to protect a toy car during a crash. Read more

NGSS Performance Expectations:

MS-PS2-1. Apply Newton's Third Law to design a solution to a problem involving the motion of two colliding objects.
MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

Do you know what enzymes are? They are like little machines that carry out many different chemical reactions that are essential for nature and our bodies. For example, they help break down the food we eat, or help make yogurt and cheese! In this activity, you will simulate an enzymatic reaction and explore what factors affect the activity of an enzyme. You only need a few simple items, including your hands, lots of toothpicks, and a timer. Read more

Have you ever seen or heard of the movies "The Mummy" or "The Mummy Returns"? Mummies have often played a part in nightmares for Western cultures, but in ancient Egypt, mummification was a serious religious ritual thought to be necessary for a person to enjoy the afterlife. In this activity, you will learn about the science behind the process of mummification by mummifying a hot dog. Read more

Exploring the Impact of Social Media on Mental Health with Machine Learning

Science Fair Project Idea

Scientific Method

Do you ever wonder if you spend too much time online? How can the amount of time spent on social media influence someone's mental health? What other factors play a role? In this science project, you will investigate which variables correlate with better mental health scores using a machine learning algorithm called the Random Forest algorithm. Read more

Fighting the Flu: How Your Immune System Uses Its Memory

Science Fair Project Idea

Scientific Method

Being sick is no fun, especially when your friends are doing exciting activities that you have to miss out on. Thankfully, common illnesses usually last for just a few days, and then you start to feel better. Why is this? It is thanks to the immune system, which is a group of special organs and cells in your body that constantly work to keep you healthy. In this science project, you will make a simple model to investigate how the immune system defends the human body from common illnesses, and… Read more

Follow the Flow

Science Fair Project Idea

Engineering Design Process

This project is inspired by the Banaue Rice Terraces, 2,000 year old structures carved into mountainsides in the Philippines. See if you can recreate the water flow of this ancient marvel, often called the Eighth Wonder of the World, using just household materials! Looking for inspiration? You can see how other students have tackled this and other annual Science Buddies Engineering Challenges. Read more

Forensics: How Does It Matter? Measure the Spatter!

Science Fair Project Idea

Scientific Method

Every criminal leaves behind evidence at the crime scene. The trick to catching the criminal is collecting all of the evidence and making sense of it. This is what the forensic expert does. In this science project you will be correlating the size of blood stains to the distance they fell, but do not get too grossed out. You will be doing it with fake blood. If you like figuring out mysteries, this is the science project for you! Read more

"Nuclear Power Plant Cattenom" © 2005 Stefan Kühn In these two activities, students will explore two consequences of burning fossil fuels: air pollution and the greenhouse effect. For a comprehensive unit on fossil fuels, this lesson works especially well as an extension to Fossil Fuels: Chocolate Chip Mining. Read more

NGSS Performance Expectations:

4-ESS3-1. Obtain and combine information to describe that energy and fuels are derived from natural resources and that their uses affect the environment
MS-ESS3-4. Construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact Earth's systems.
