How do you make a stem catapult?
Directions for Making Popsicle Stick Catapults
- Make a stack of popsicle sticks and rubber band them together on each end.
- Take two additional popsicle sticks and stack them together.
- Pull the two popsicle sticks slightly apart and place the larger stack of popsicle sticks in between them.
What makes a catapult work for kids?
A catapult works like a lever, which is a simple machine. When you push down on one end of the lever and then let go, it changes the direction of the force and pushes the marshmallow in the opposite direction. Levers are used all around us. For example, a seesaw is a lever and so is a pair of scissors!
How do you make a catapult out of household items?
Simple craft stick catapult:
- Stack five craft sticks together and wrap a rubber band around each end.
- Stack two craft sticks and wrap a rubber band around only one end.
- Slide the five sticks in-between the two sticks, as shown.
- Wrap a rubber band where the two sections meet to hold the catapult together.
What kind of science is a catapult?
The catapult science basically involves some physics and engineering skills to hurl a projectile without the use of an explosive. It works mainly by using potential and kinetic energy stored in the rubber bands. Potential energy is the store energy where as the kinetic energy is the energy in motion.
What are the 3 main types of catapults?
Many different types of catapults were invented and used. Three of the most common were the ballista, the mangonel, and the trebuchet.
What is the science behind catapults?
A catapult works because energy can be converted from one type to another and transferred from one object to another. This energy is stored in the launching device as potential, or stored, energy. The catapult you are about to make uses elastic potential energy stored in a wooden stick as you bend it.
How do you make a catapult without hot glue?
The simplest catapult to make Take 9 popsicle sticks and secure them with a rubber band on one side, then take a popsicle stick, place it between some of these vertically and secure the second end. Now take a plastic spoon and attach it to the vertical stick with a rubber band. You are done!
How are catapults used in science?
A catapult works because energy can be converted from one type to another and transferred from one object to another. When you let go, this stored energy is released, converted into energy of motion and transferred to the missile (the launched object), which then flies through the air.
How many simple machines are in a catapult?
When you build a catapult with three simple machines as part of the design (lever, pulley, screw), you add multiple levels of complexity to an already elegantly conceived machine.

What is a simple catapult?
A catapult is a type of machine used as a weapon to shoot rocks or other things that would cause damage to something else. Catapults use weights and levers to send the rocks or other things into the air. They are simpler than other modern weapons and not useful in modern warfare. Catapults were common in the past, especially the Middle Ages.
