Stem Fair Project Ideas

Stem Fair Project Ideas Intro

A day comes when your 8th-grade student has brought home an assignment vital to their tutor. The job is a science fair project or  Stem Fair Project Ideas and interests a lot of work. The student must follow the teacher’s schooling to ensure their project meets the needed standards. Now you have to think of the stem fair project ideas. These can involve any science, technology, engineering, or mathematics experiments.

Though it may sound easy, selecting the one for showcasing is hard. The reason is that other kids may come up with the same idea. And your child may have to find a new one. Here is a list of some of the best and easy stem science fair project ideas.

1. Check Lungs Capacity

It is one of the easiest stem fair projects for the 8th graders or below. The materials you need are a balloon and a measuring tape. Inhal as much air as you can and exhale all the air into the balloon. Measure the size of the balloon with the measuring tape. That is how much air your lungs can breathe in.

2. Create a Better Lightbulb

To make a lightbulb, you should create one with a jar, a wire, and a 6-volt battery. Then, you can experiment with different materials. To make a lightbulb that lasts longer burns brighter or is powered by an alternative source.

3. Test How Stress Affects Body Temperature

Another easy stem fair project idea any student can perform. Conduct this experiment using a thermometer, stopwatch, and a few volunteers. Assign simple and easy puzzles or mathematical challenges to the volunteers. So, first, record the body temperature of a volunteer with the thermometer. Then let the challenge begin. Use the stopwatch for 5-10mins. Stop the timer, and record the resulting rise or drop in the body temperature. Compare the effects of different level tasks on the body temp of the volunteers.

4. Can a Carbonated Drink Affect Meat?

Scientists tested the hypothesis that soda can digest meat as our stomachs do. They covered a meat container with different sodas and observed how the meat changed over time. The data showed that the meat did digest better with soda than with other liquids. You can use any three different types of meat for this experiment. Store each meat with two or more soda drinks in three separate bowls. Leave it for 30-40mins. And see how the carbonated drink affects the meat, fish, beef, chicken, etc.

5. Robotic Hand Designing

It is a project you can change and improve with as much creativity as possible. Using any material, you can make the robotic hand model with your own ideas. With a hand that can pick up a ball or plucks up a piece of string, there are many prospects. The aim is to show a robotic hand that works under your control. Children also love this project because it is creative, and they can use toys like Lego, blocks, etc.

6. Newton’s Cradle

Building a Newton’s Cradle at home is easy. However, it will shock the 8th grader’s classmates as a difficult-to-make project. All you need to do is tie strings in a triangular shape with a button, marble, or small ball hanging. You can explore various images available on Google as a reference. You can create the platform using cardboard, hardboard, or softwood. So, each time you throw a marble or small ball, it will move the others with the same momentum, repeating various times.

7. Blocking Sun UV Rays

It is one of the easiest stem fair project ideas. Use color-changing UV beads to test the protection of pill bottles, hats, clothing, and more. It is an 8th-grade science experiment with almost endless possibilities.

8. Create a Cup Holder

Can your 8th-grade science investigator make a sturdy block that can hold two glasses of water with any material? The answer is yes, and it takes only 5 minutes. This limited-time challenge pushes the limits of their creative engineering. They can use straws, plastic, disposable glasses, sticks, cardboard, etc. All you have to do is to balance the two glasses holding some water.

9. Water Test

Testing water quality is interesting and a great learning experience for the student. Use any water testing kit for this experiment to determine the TDS levels. You can also use the tap water supplied to your home. So the kid can check for you the water grade.

10. Create a Spring Scale

It is one of the easy DIY stem fair projects/part of Stem Fair Project Ideas with a lot of creative potential for the students. Use Hooke’s Law to see if a spring that stretches can measure any object’s weight. The material is simple, but you need patience and physics to calibrate the spring and use it for weight testing.
