Rocket Science

Contributor: Rebecca Highland. Lesson ID: 10376

How many people does it take to push a big rocket into the air? Thanks to Isaac Newton, we can get rockets into space and balloons to zip around the room. Bill Nye, Newton, and Science Bob teach you!

Have you ever wondered how a huge rocket can rise from the ground all the way up to space?

In this lesson, you will learn about how it is possible to launch a rocket into space like NASA has done many times!

2. According to Newton’s Third Law of Motion, for every action, there must be an equal and opposite reaction. You use this principle every day! To understand this idea more, watch Newton's 3rd Law Of Motion | Smart Learning For All | Animation | Physics | NPS below:

 

3. Now think about a rocket. Rockets are huge! How can the space program possibly get such a heavy, large object all the way into space? This action requires force, and a lot of it!

Scientists have found a way to produce enough action force to create a reaction that sends a rocket hundreds of miles away from Earth and up into space! Fuel is burned to produce gas, and the gas is pushed out the back of the rocket, causing it to rise up with enough force to get into orbit — or even to the moon! This force is called thrust.

Thrust helps an object work against gravity. On Earth, gravity is a natural force that is always trying to get objects on the ground. A rocket's thrust is powerful enough to push a huge object, like a rocket, against gravity and up into space.

Here are a few more resources that explain force and motion, starting with the Force and Motion - Bill Nye Clip below:

 

4. Discuss what you have learned about force and motion with your teacher.

Elephango's Philosophy

We help prepare learners for a future that cannot yet be defined. They must be ready for change, willing to learn and able to think critically. Elephango is designed to create lifelong learners who are ready for that rapidly changing future.
