What's The Best Way to Land a Model Rocket?

Science Fair Project Idea

Scientific Method

What's the best way to land a model rocket? What makes the rocket hit the ground safely at a low speed? What prevents the rocket from drifting too far if it's windy? In this project, you will make your own rockets from paper towel tubes and drop them to test different recovery methods like parachutes and streamers. What method do you think will work the best?

Do you enjoy ice-cold drinks? A slushy is about as close as you can get to liquid ice: colder than water, but more drinkable than ice! Using some common household items, a little bit of patience, and the help of science, you can make this delicious, sweet drink at home. Try the activity, and you will be rewarded with a delightful treat! Read more

Build Obstacle-Detecting Glasses for Visually Impaired People

Science Fair Project Idea

Engineering Design Process

Many visually impaired people use canes to detect obstacles at ground level. What about detecting an obstacle at face level, like a tree branch? What if you need to keep both your hands free and cannot hold a cane? Solve both problems at once with these obstacle-detecting glasses! The glasses use an ultrasonic sensor to measure distance and a buzzer to alert the user of nearby objects. You can customize the design to add or swap out features, like using a vibration motor instead of a buzzer.… Read more

Can Plants Stop Soil Erosion?

Science Fair Project Idea

Scientific Method

Soil erosion can cost the world billions of dollars every year by washing pollutants into our streams and rivers and by causing the loss of farmland. What can you do about this problem? Help save the world (and some money!) with nothing more than a few plants! Read more

Measuring the Amount of Acid in Vinegar by Titration with an Indicator Solution

Science Fair Project Idea

Scientific Method

Have you ever wondered why some foods taste really sour? Vinegar is one example that you might know from salad dressings or pickles. They taste pretty sour, right? There are many different types of vinegar that you can buy to use around the kitchen for cooking and pickling. The chemical compound that gives vinegar its tart taste and pungent smell is acetic acid. Do you think all the different vinegars contain the same amount of acetic acid? Are there some that are more sour than others? How… Read more

When light interacts with an object, it can be absorbed, transmitted, or reflected. This lesson focuses on materials that reflect light. Specifically, students will use mirrors and flashlights to investigate how light is reflected from a surface. By doing that, they will discover that when a light ray hits a reflective surface, its angle of incidence is equal to the angle of reflection, which is stated by the law of reflection. Students will then use their gained knowledge in a mirror maze… Read more

NGSS Performance Expectations:

MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
MS-ETS1-4. Develop a model to generate data for the iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

Are Fingerprint Patterns Inherited?

Science Fair Project Idea

Scientific Method

Have you ever looked at two girls and thought they looked so similar that they must be sisters? What about a father and his son — have you ever seen a boy who looked just like how his father did when he was younger? We can often tell that two people are related because they appear to have several similar physical traits. This is because children receive half of their DNA — their genetic blueprints — from each parent. What about fingerprints — are they an inherited trait?… Read more

Burning Calories: How Much Energy is Stored in Different Types of Food?

Science Fair Project Idea

Scientific Method

Have you ever wondered how nutritionists know how many Calories a certain food contains? In this project you will learn a method for measuring how many Calories (how much chemical energy) is available in different types of food. You will build your own calorimeter to capture the energy released by burning a small food item, like a nut or a piece of popcorn. This project gives a new meaning to the phrase "burning calories!"

What if you could take a single liquid, and change it into a rainbow of colors without using food dye. You can! In this activity you will use red cabbage to make what is called an indicator solution. Indicator solutions can change colors depending on what you add to them. In this case adding something acidic (like lemon juice) will change it to one color while adding something basic (like bleach) will change it to another. Try and see how many colors you can make using different household… Read more

How Does Color Affect Heating by Absorption of Light?

Science Fair Project Idea

Scientific Method

Why is it more comfortable to wear light-colored clothes on a hot summer day? Why wear a dark-colored jacket for early-morning fishing on a cold lake? How much difference can it make? Here's a project where you can quantify how much difference color makes for absorbing heat. Read more
