Cryopreservation: Freezing Plant Tissues

Science Fair Project Idea

Scientific Method

Cryopreservation—storing seeds in ultra-cold liquid nitrogen—is one method for maintaining plant genetic stocks in seed banks. Can seeds withstand a really deep freeze and still germinate? Read more

Decisions, Decisions: Judging a Book by Its Cover?

Science Fair Project Idea

Scientific Method

This project challenges you to think like a politician (and a scientist!), and try to ascertain what factors are most important as individuals make their decision on how to vote. For example, is it what is being said, or who is saying it? Read more

Deep Knee Bends: Measuring Knee Stress with a Mechanical Model

Science Fair Project Idea

Scientific Method

Are you interested in things like prosthetic limbs and artificial joints that can help people with disease or injury to lead a normal life? Or maybe you're interested in sports medicine or physical therapy? Either way, this project could be a good match for you. Find out how the tension on the knee joint changes as a function of angle by building a simple mechanical model. Read more

Deforestation

Science Fair Project Idea

Scientific Method

The conversion of forested to unforested areas has been occurring since humans began to impact and change their environments during the agricultural revolution. Recently deforestation has become a global problem, particularly for developing industrial countries and countries with very large populations. You can use satellite mapping resources to investigate the connection between urbanization, population growth and deforestation. You can also investigate the connection between deforestation… Read more

In this lesson, students are challenged to design and build a controlled-release tablet, which will be made from different colored bath tablets and a variety of water-soluble plastics. First, they will have to test the properties of each of the different plastic materials. Then their task will be to create a tablet that releases three different colors, each at a pre-determined time after the tablet has been submerged in water. As students design and build their controlled-release tablets, they… Read more

NGSS Performance Expectations:

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-ETS1-3. Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.

Design a Game to Help Alzheimer's Patients

Science Fair Project Idea

Engineering Design Process

Alzheimer's disease and dementia affect millions of people around the globe. Can you design a "brain training" game that can help people keep their brains healthy as they age, and maybe one day help treat or even prevent diseases like Alzheimer's? Try this coding science project to find out! Read more

Forests are the green lung of the Earth and home to millions of different plant, fungi, animal, and bacteria species. Unfortunately, today many forests are threatened by deforestation, which causes significant biodiversity loss. Ongoing reforestation efforts across the world intend to counteract the effects of deforestation. As planting trees by hand does not scale well, machines on the ground, as well as flying drones have been developed to help plant tree seedlings or seeds. In this lesson,… Read more

NGSS Performance Expectations:

MS-LS2-5. Evaluate competing design solutions for maintaining biodiversity and ecosystem services.
MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of a problem.
MS-ESS3-5. Ask questions to clarify evidence of the factors that have caused the rise in global temperatures over the past century.

Design Clothing with Built-In Sensors

Science Fair Project Idea

Engineering Design Process

Have you ever worn a costume that lit up or played sound? Have you ever wished you had a suit of armor with built-in moving parts like a superhero? What if you could make your costume or suit react to your own movements or even other people who bump into you? The Science Buddies activity Weaving a Wearable Touch Sensor shows you how to make a capacitive sensor that responds to touch and can be woven directly into fabric (Figure 1). Can you design a piece of clothing that includes one… Read more

Design Your Own Video Game with a Raspberry Pi

Science Fair Project Idea

Scientific Method

Do you play video games on a console or smartphone? Have you ever wished you had the power to change how a game worked, or even to create your very own game? This project will show you how to make your very own video game and controller using a Raspberry Pi. Check out the video to see what this simple, but fun, project looks like. Of course, you can design the looks and gameplay of your game any way you like! IMPORTANT: The instructions for this project were originally written using Scratch 2… Read more
