Excellent article on how the VdG works

PHET simulation on charging a balloon
Animation(repulsion of 2 positives), attraction, 2 negatives

Nice animations at http://www.physicsclassroom.com/mmedia/estatics/isop.html

 

Structure of Matter

There are three very good videos presented by Brian Cox in a series called "In Search of Giants" described and linked here. The first is particularly relevant.

Look at what happens to the  the molecules of water as it changes from a solid to a liquid:

PHET simulation: States of Matter

The water molecules have an imbalance of charge which makes the Hydrogen parts of one molecule want to stick to the Oxygen parts of another molecule, this is called "Hydrogen bonding".

Springs

 

Robert Hooke (http://www.roberthooke.org.uk/) Robert Hooke was not only responsible for “Ut tensio sic vis” but also a good deal of building and mechanics. Find out more at this site to appreciate his contribution not only to our understanding of forces, but also his rivalry with Newton.

 

Virtual Hooke’s Law Lab (http://www.4physics.com/phy_demo/HookesLaw/HookesLaw.html). A nice little applet to take you through the basics.

 

Using spreadsheets in physics (http://www.stpaulsschool.org.uk/page.aspx?id=12918) – how to avoid the common pitfalls.

 

Exercises on the Intranet for the plotting of graphs using Excel for data from a spring and from an elastic band

 

Wikipedia (http://en.wikipedia.org/wiki/Hooke's_law) goes beyond what you need but good on how Hooke’s Law relates to materials.

 

University of Liverpool matter pages (http://www.matter.org.uk/schools/Content/HookesLaw/index.html) with nice animations and simple explanations.

 

 

 

 

Forces, Weight and Pressure

Good revision link:

          http://www.bbc.co.uk/schools/ks3bitesize/science/energy_electricity_forces/forces/activity.shtml

          (moments will not be on the January test but pressure will be)

 

          the 'Magdeburg hemispheres' experiment:

          http://www.daviddarling.info/encyclopedia/V/von_Guericke.html

 

         Watch the Mark Steel lecture on Newton, download it from here:

          Forces on an apple animation

          Newton's laws 

  Visualizing Newton's 3rd Law

Animated exercises - place objects in order of density, select the fake crown

 

 

         Cartesian diver 

 

Revision PowerPoints: Densitypowerpoint.ppt    density.ppt (harder)

          Diameter of the Moon Activity [101KB PDF file] 

          This activity requires that students calculate the diameter of the moon by comparing it to a two-centimeter cardboard disc.

  

You will find a lot about solar eclipses, lunar eclipses and pinhole cameras on the web, some examples below: 

http://sunearth.gsfc.nasa.gov/eclipse/eclipse.html NASA page on solar eclipses

http://www.bbc.co.uk/science/space/solarsystem/sun/solareclipse.shtml BBC page on solar eclipses

http://www.eclipse.org.uk/ Almanac of eclipses

http://www.bbc.co.uk/science/space/solarsystem/earth/lunareclipse.shtml BBC page on lunar eclipses

http://en.wikipedia.org/wiki/Pinhole_camera Wikipedia article on pinhole cameras

http://www.learner.org/teacherslab/science/light/ An excellent site, though of a demanding level. It covers shadows from multiple sources, coloured shadows, spectra and parallax by using a mixture of text and Java animations. The questions and puzzles are quite demanding – for example working out what a four-eyed alien would see, and where a player is on a pitch by looking at the strength and shape of his shadows.
Applet  Teaches you about shadows – includes some points about colour which are more than you need to know.

Lunar Eclipse Applet  As it says on the tin!
