It is almost mid-summer! You might have colorful flowers, fresh tomatoes and yummy berries in the garden. But wait, did you remember to water them? Maybe you wonder if they get enough, too much or too little water. Should you water every day, twice a day or once a week? Should you soak the ground, or is frequently providing small amounts of water better? Unfortunately, there is no general rule, because much depends on the type of soil. In this science project, you will see how much water… Read more

Wave Blockers

Science Fair Project Idea

Scientific Method

What do the radio, TV, radio controlled cars, and cell phones all have in common? They all use invisible waves to transmit information. Find out which materials block radio waves, and which materials allow radio waves to pass through by doing this experiment. Read more

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

Wearable Limp Detection Device

Science Fair Project Idea

Engineering Design Process

Have you (or anyone you know) ever sprained an ankle or broken a leg? It might have taken some practice to walk again after recovering from an injury. Some people might even need to work with a physical therapist. In this project you will program a wearable device to recognize when someone is limping instead of walking normally. Read more

Weather and Climate in Your Neighborhood

Science Fair Project Idea

Scientific Method

Do you live in an area where the weather changes a lot from season to season throughout the year? Or do you live in a place where the weather stays pretty much the same all year long? How dynamic is the weather, and how does it compare to climate? In this experiment you can use the Internet to conduct your own investigation about how climate and weather in your local area change over time. 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.

NGSS Performance Expectations:

MS-ESS2-1. Develop a model to describe the cycling of Earth's materials and the flow of energy that drives this process.

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

Have you ever wondered how whales and other marine mammals survive and keep warm in the cold oceans? Warm-blooded mammals can live in these chilly conditions because their bodies have some cool warmth-saving adaptations, thanks to generations of natural selection. In other words, to pass on characteristics (via their genes), the predecessors of modern marine mammals had to overcome different challenges to reproduce, and their descendants received the genes that allowed for their survival.… Read more

What Are You Blubbering About?

Science Fair Project Idea

Scientific Method

Baby Beluga may swim in the deep blue sea, but the song does not mention how cold it is out there! Find out in this science project how a bit of blubber can be a useful adaptation when the water is ice cold. Brrrr! Read more
