Space Explorers

Key Learning Goals - Science:

3.2 Be able to conduct scientific investigations:

The big idea

We know that when we look up at our sky we will see the Sun, the Moon and the stars. We take them for granted. But why are they there? What do they do? How do they affect the Earth? Astronomy, like all sciences, is about asking questions. By becoming space explorers, we can find out more about our solar system and the deeper mysteries of the universe.

During this unit we will be focusing on Science, History, Art, Technology and International.


In Science, we’ll be finding out:


In History, we’ll be finding out:


In Art, we’ll be finding out:


In Technology, we’ll be finding out:


In International, we’ll be finding out:

Solar System

In this BrainPOP movie, Tim and Moby take you back to the birth of our home in space and give you a virtual tour of our galactic neighborhood! You’ll find out how long ago the solar system took its first baby steps, as well as the process by which the sun and planets actually formed. Find out about the two different categories of planet in our solar system, and meet each of the individual planets--plus other solar system bodies like dwarf planets and asteroids! 


In this BrainPOP movie, Tim and Moby spout off fun facts about the huge clump of stars that Earth and the rest of the solar system is a part of! Find out just how many stars there are in the Milky Way (hint: it’s a LOT!) as well as what exactly makes up a galaxy like ours. You’ll discover what the Milky Way looks like from afar and why it looks like a big milky blob from Earth. You can also see where we’re located in the galaxy and how long it would take for us to orbit around the galaxy’s center — where astronomers think something mysterious might be lurking!

Space Flight

Ever wonder how spaceships leap off the planet and fly into outer space? In this BrainPOP movie, Tim and Moby will teach you the basics of space flight! First, you’ll get a brief lesson on the physical forces that send spacecraft zooming into space. Next, you’ll learn some of the main concepts of rocketry, including the all-important force called thrust. You’ll also gain an understanding of the two basic types of rockets and how they work to get spacecraft off the ground. And you’ll learn a bit about various types of spacecraft and the rockets they use to become space-bound.


In this BrainPOP movie Tim and Moby will set you straight about our one and only natural satellite. Learn why the moon shines so brightly and why it goes through all those crazy phases. Discover what’s on the surface of the moon and why you can see some of those features with just your naked eyes! Since we don’t really know how the moon formed, you will also find out about the four main theories that scientists have on how it all started long, long ago! 


In this BrainPOP movie, Tim and Moby share all they know about our favorite red planet. You’ll learn why Mars really is red, and why it’s the planet most like our very own Earth. You can also meet the two moons of Mars and find out where they came from. Want to know about Martians? You’ll discover what we know about water and life on Mars, as well as whether humans could ever survive there.
