Wearables are found all over the biomedical world: heart rate monitors, EKG patches, braces, etc. In this project, you will make your own wearable air quality sensor that notifies you of high-risk air. You can attach the sensor patch on any existing clothing or even make a standalone patch that you can wear as a necklace or a bracelet. Read more

Weather Stations and Weather Forecasts: Can You Do It Yourself?

Lesson Plan Grade: 3rd

How do scientists know what the weather will be like in the future? In this fun weather lesson, students set up a weather station and collect data such as sky coverage, temperature, and rainfall. As they identify connections in their data, students will realize that these connections can help forecast what the weather will be like in the short-term future. The lesson culminates in students making and presenting a weather forecast for their fellow students. Read more

NGSS Performance Expectations:

3-ESS2-1. Represent data in tables and graphical displays to describe typical weather conditions expected during a particular season.

In this lesson, students explore weathering—the wearing away of rock by exposure to the elements. They learn how it creates smooth boulders, rounded pebbles, sinkholes to swim in, and caves to explore. In the activity, they explore the connection between weathering and sand using sugar cubes.

Sensors are everywhere—on your phone, in your car, and even at the grocery store. Learn how to craft your own wearable sensor that you can put on your clothing. Using a simple and easy crafting method, you will be able to weave your own capacitive touch sensor patch that will detect when someone touches the fabric. You can use the sensor to turn on an LED, buzzer, or motor when it detects touch! Read more

What A Drag!

Science Fair Project Idea

Scientific Method

What makes some objects more streamlined than others? Find out which ordinary objects around your house are made to move smoothly through the water in this easy science fair project. Which objects will produce the most drag when pulled through the water? Read more

What Color Are the Leaves Really Turning?

Science Fair Project Idea

Scientific Method

Everyone loves the beautiful colors of fall, but where do they come from and how does the change in colors happen? In this project, you will uncover the hidden colors of fall by separating plant pigments with paper chromatography. What colors will you see? Read more

What Do Enzymes in Pineapple Juice Do to Milk?

Lesson Plan Grade: 5th

In this fun chemistry lesson, students will explore chemical reactions by mixing pineapple juice and milk. Students will observe whether the properties of milk change when it is mixed with pineapple juice, as well as how they change. They will then infer from their results whether a chemical reaction happened. In the process, they will not only learn about chemical reactions but also discover the importance of enzymes and their role in the human body. Read more

NGSS Performance Expectations:

5-PS1-4. Conduct an investigation to determine whether the mixing of two or more substances results in new substances.

What Do We Do With Our E-waste?

Science Fair Project Idea

Scientific Method

If you made a pile of all the electronic devices (cell phones, computers, stereos, televisions, MP3 players, video game systems, remote-control toys, etc.) that your family has gotten rid of since you were a baby, how big would that pile be? Would it be taller than you? Would it fit better in a wheelbarrow or in a pickup truck? And did they just throw it in the trash? In this science project, you'll explore what people in your community do with electronic waste, commonly called e-waste, and… Read more

Have you ever wondered how fish hear the sounds we make when we splash into the water or pass by in a motorboat? Now that the summer vacation is here, you might be spending more time in the water: an ideal occasion to investigate how we hear in the water! Maybe you will feel inspired to research how that transfers to aquatic animals, too! Read more

What is the Woolly Mammoth's Closest Living Relative?

Science Fair Project Idea

Scientific Method

Woolly mammoths shook the ground of ice-age tundras for millennia, living next to saber tooth tigers and prehistoric man. Although they have been extinct for thousands of years, scientists continue to learn more and more about this mighty animal. Some of the most exciting new research is being produced by looking at DNA extracted from the hair and bones of woolly mammoths entombed in ice. In this genomics science fair project, you will use bioinformatics tools to determine the woolly mammoth's… Read more
