Explore how technology can save lives in this fun engineering lesson plan! Earthquakes can cause devastation and loss of life when they strike, but earthquake-resistant buildings can stay standing and keep people safe. In this project, your students will build model earthquake-resistant buildings and measure their movement during a simulated earthquake using a mobile phone and a sensor app. A French translation of this activity is available.

NGSS Performance Expectations:

MS-ESS3-2. Analyze and interpret data on natural hazards to forecast future catastrophic events and inform the development of technologies to mitigate their effects.
MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

Can AI Classify Stars?

Science Fair Project Idea

Engineering Design Process

Understanding the different types of celestial objects in our galaxy is important for astronomers. It helps them study how these objects form and evolve, map the night sky, understand the structure of the Milky Way and other galaxies, and identify celestial bodies that might host habitable environments. In this project, you will create a boosted tree model to classify celestial objects based on their spectral characteristics. Read more

Can AI Diagnose Breast Cancer?

Science Fair Project Idea

Scientific Method

Getting started with machine learning is like unlocking a new world of possibilities, and the best part is that you don't need to be a computer genius to do it! In this project, you will create a K-Nearest Neighbors (KNN) machine learning model that can predict whether a patient has a benign tumor or malignant breast cancer based on the characteristics of the tumor cell nucleus, such as its radius, perimeter, area, and smoothness.

Can Cell Phones Survive a Drop Test?

Science Fair Project Idea

Engineering Design Process

Why do so many people use cell phone cases? Do cell phones really need the extra protection, or is it just because cases look fancy? In this engineering science project, you will test the durability of calculators instead of cell phones, find out if cases increase the durability of the device, and build some of your own cases that do!

Can Water Float on Water?

Science Fair Project Idea

Scientific Method

Of course it can, you say: ice is water and ice floats! And you're right. But we're talking about water in the liquid phase (the title reads better without getting overly specific). So how about it? Can liquid water float on water? Check out this project to find out. Read more

Can You Train People to Breathe Better?

Science Fair Project Idea

Scientific Method

The practice of "belly breathing" has been linked to improve mood, relaxation, and even have physical benefits like lowering your heart rate when compared to chest breathing. However, most of the time, we do not think about breathing—our bodies do it automatically. How do you know if you are belly breathing instead of chest breathing? How can you practice and get better at it? In this project you will build your own device to provide visual feedback about how a person breathes, then see… Read more

Chemistry of Baking Ingredients 1: How Much Baking Powder Do Quick Breads Need?

Science Fair Project Idea

Scientific Method

If you like to bake, this could be a good science project for you! Have you ever wondered about the purpose of each of the ingredients in your favorite recipes? For example, why is baking powder used in some muffin recipes? How does the baking powder affect how the muffins look, feel, and taste? In this food science project you will use a scientific method to find out! Read more

Aircraft carriers are much shorter than a typical airport runway. How do airplanes manage to gain enough speed for takeoff over such a short distance? A catapult gives them an extra boost! In this lesson, your students will practice engineering design as they build their own paper airplane launchers, while learning about kinetic and potential energy. Read more

NGSS Performance Expectations:

MS-PS3-2. Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system.
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.

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
