Have you ever watched a fireworks show and wondered how all the different colors — amazing reds, yellows, oranges, blues, purples, greens, and more — are made? The color, or colors, that a firework makes depends on what color-producing chemicals are in the firework. These chemicals are various metal salts that burn when the firework goes off, and burning the metals is what makes the colors. Different metals give off different, specific colors. In this science activity, you will get… Read more

Do Submarines Need Fins?

Science Fair Project Idea

Scientific Method

What keeps a submarine from spinning out of control? In this science project, you can investigate how submarines use stabilizing fins to move forward. You might even figure out the secrets to maneuvering a submarine! Read more

In this lesson, students will role-play a consultation between a plant scientist and a plant owner. The goal is for the plant scientist to identify what is wrong with the plant based on the information given by the plant owner. As they evaluate what the unhealthy plant has or doesn't have, students will realize that plants need four things (air, water, light, and soil) to live and grow. Read more

Do you know where your drinking water is coming from? Sure, it comes out of your faucet, but how does it get there? Drinking water all over the world originates from either surface waters—such as lakes, reservoirs, and rivers—or from underground sources, such as groundwater. But would you want to drink water straight from a river or lake? Probably not; they can be really dirty and muddy! To become clean and safe, this water first has to undergo several treatment processes; the first… 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.

Exploring the Chemistry of Red Flower Pigments

Science Fair Project Idea

Scientific Method

Are all reds the same? Find out in this science fair project! Investigate if the pigments in one type of red flower are different from those in another type of red flower. Flowers contain an assortment of amazing chemicals that produce color. In this plant biology project, you will analyze the colored pigments in different plants' red flower petals using paper chromatography, and compare the pigments in the different flowers. Read more

Feel Sound With Your Fingertips: Ultrasonic Haptics

Science Fair Project Idea

Scientific Method

Virtual reality headsets can make you see something that isn't really there, but can you feel an object that isn't there? In this project, you will build a device that lets you feel invisible sound waves in midair. 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

Fish + Food = Science of Aquaponics

Science Fair Project Idea

Scientific Method

How are we going to feed the more than 9 billion people that will live on Earth by 2050? This is a major question for farmers, ranchers, and food scientists around the globe. It's a big problem, considering that from 2017 to 2050 we will be adding 1.5 billion people and need 20% more food. Linked to this problem of producing enough food is having enough land, water, and other natural resources to make that happen. The final solution will surely be made up of many different approaches working… Read more

Growing Plants on Mars

Science Fair Project Idea

Scientific Method

To be able to live on Mars, humans need breathable air, clean water, and nutritious food. Spacesuits can provide oxygen to breathe, ice on Mars can be a source of water, but how could we get nutritious food? Today's astronauts bring food with them. But a manned trip to Mars would require food that was either successfully grown in space or on Mars, as taking the extra weight of food for such a long time—it takes 6–9 months one way—is just too costly. In this project, you will… Read more
