Nothing
What I did for a 4th grade, was a balloon-powered car. For older grades you want to make it cool and a different project.
I did this one year 'how does the air temperature effect the size of the balloon
no it cant i looked like a fool doing a science project like this one
testing if temperature affects the maximum size of the inflation of a balloon
A mousetrap car
i dont know i ende help too for my science project
For a hot air balloon science project, you can create a small-scale model using materials like tissue paper, glue, a straw, and a small basket. Show how heating the air inside the balloon with a hairdryer causes it to rise. You can also experiment with different temperature air or sizes of balloons to see how they affect the flight.
a balloon car works by the air in the balloon.
Ah, when creating a balloon-powered car, the manipulated variable is the one you change on purpose to see how it affects the car's performance. This could be things like the size of the balloon, the type of material used for the wheels, or the angle of the straw. Remember, it's all about experimenting and having fun to see what works best for your unique creation.
A motor pulley car science project typically involves attaching a small motor to a car chassis, with a pulley system to drive the wheels. By adjusting the size of the pulley, you can explore how different gear ratios affect the speed and torque of the car. This project demonstrates basic principles of mechanical advantage and gear systems in a hands-on way.
