Force in Action: Videos and Interactives

This guide has been created to support the Year 4 Science program.

Physics of a slinky drop: ABC Education

This video runs for 3 minutes and 43 seconds. This is one your students will really enjoy.

Imagine holding a slinky by the top end, with the bottom end dangling in mid-air. What do you think would happen when you let it go? Explore the physics of two equal and opposing forces working on an object in this awesome experiment!undefined

Darts vs Gliders: ABC Education

This video runs for 36 seconds. It explores friction through experimentation with different styles of paper planes. This is actually part of a series of videos on paper planes and you should be able to find links to the others from this video.


G-force action

This video runs for 3 minutes and 50 seconds. It explores the question What effect does g-force has on the human body?

Peter Rowsthorn visits the Australian International Air Show to answer the question. Join Pete in the cockpit of a light plane for some aerobatics with pilot David Pilkington. G-force expert Dr David Newman explains the science as Pete endures up to 6 g in the aircraft.


Electricity and Magnetism: Exploratorium Science Snacks

This site explores electricity and magnetism. It has many short (some only seconds long) videos which demonstrate magnetic forces under varying conditions. There are lots of really good demonstrations on the second page.


Electromagnet Basics: ABC Education

This interactive requires the use of FLASH. It allows students to explore the parts of an electromagnet circuit and to test objects made of different materials to find out whether they are affected by magnetic fields. 


Friction between paper video: ABC Education

This video runs for 2 minutes and 16 seconds. Questions posed include: Are you strong enough to pull two sheets of paper apart? What about two books with the pages intertwined? Watch this science experiment performed by Ruben Meerman, the Surfing Scientist, and find out how he tests the presence of friction between pieces of paper.


Electromagnetism variables: ABC Education

This interactive requires the use of FLASH.  Students can investigate how the strength of an electromagnet can be changed, drop a steel can past an electromagnet and see how its path is curved, change the number of batteries, the number of turns in the coil and the core material of the electromagnet and observe the effect.


DIY electromagnets

This video can be located on EnhanceTV. (Connect - Library Resources - Primary Library Databases - EnhanceTV. Be sure to click on the link to ensure you are automatically logged on.) You may find other helpful videos using the filters. I used the search term 'magnet' and then filtered by Subject = Science, Grade = Year 4.

Summary: 2 minutes, 19 seconds. Join junior scientist Jack as he builds an electromagnet using a D-sized battery, coated copper wire, a nail file and some metal nails. Electromagnets are created when an electrical current is passed through a tightly wound coil, causing an electromagnetic field. Being able to control the magnetic field, by changing the amount of electricity passing through the coil, gives the user the ability to turn it on or off at will, and making it advantageous over the permanent magnet.
