Year 4 are studying how forces interact in our world to create motion.  They will learn about Newton's three laws of motion and how these apply to all of the interactions of forces in our world. Here is some inspiration to get you going!

ISAAC NEWTON (1643-1727) is considered one of the greatest scientific minds and his 3 laws of motion revolutionised our understanding of physics.  
Try out some of the links to the right to explore Newtonian physics in more detail
Newton's Laws of Motion: Interactive - Science Channel

Bumper Car Physics - Great interactive using bumper cars to test your understanding of Newton's Laws

Newton in Space - Astronauts on the International Space Station explain physics in space

Newton's Laws of Motion and Car Physics - an excellent webpage with a lot of links to many sites. Suggested by Christian a young visitor to our website from Pennsylvania, USA!! Thanks, Christian!
GOLDBERG TO GO!
A fun online activity from PBS Kids to tweak a Rube Goldberg machine to make it work.  It also has good information and tips for building your own Rube Goldberg machine. 
AUDRI'S RUBE GOLDBERG MACHINE
Let a 7 year old loose with scrap material around the house and LOTS and LOTS of persistence and it's amazing what they can achieve!
THE NEXT LEVEL!

Rube Goldberg machines are taken to a whole new extreme by the rock band OK Go in the music video for their single This Too Shall Pass.


Watch and be amazed.
AND NOW FOR SOMETHING COMPLETELY DIFFERENT....

This advertisement for a new phone from Japanese telecom company NTT DoCoMo features lots of great physics - obviously Newton's Laws but also the physics of sound.  

The Ultimate Paper RollerCoaster

In 2015 Year 4 students made paper roller coasters to demonstrate their understanding of forces and motion. Check out Andrew Gatt's fabulous roller coaster below as well as the students creations.  
Andrew Gatt’s paper roller coasters are not only fun, but they also teach many lessons in engineering, construction, teamwork, trial and error, and more. In exploring physics alone, DIY roller coasters can start conversations about kinetic energy, potential energy, gravity, friction, velocity, and acceleration, to name just a few.
