Density

http://phet.colorado.edu/en/simulation/density  this is a great little game that allows you to change the mass and volume of different objects and calculate the density.

Remember the formula for Density                        Density = Mass
                                                                                               Volume

Build a molecule

This is a great website which links you to a game where you can build molecules.!!  For Junior Cert Science you need to know how atoms bond using Ionic Bonding and Covalent Bonding.  It shows 3D representations too which makes it easier to visualize.

Have a go!!!

Electrical Circuits

If you click on the link below it will take you to a game about electrical circuits.  You can see how we write them in diagram form too using the correct notation.  For my second years this applies to the little circuits we set up to test the conductivity of metals.  We had a power source like they have the battery and instead of having a bulb light up we used an ammeter.  Note how the circuit is complete - a full circle!!!! It all has to join continuously for the bulb to light.  In our experiment the metal was placed between the 2 crocodile clips to complete the circuit and move the needle on the ammeter!!   Have a go....good luck.

Microbiology

Have you ever wondered about all those little microbes out there that we can't see!! Do they help us in our everyday life or hinder us?  Have a look at this website and discover the world of Microorganisms.
Our Junior Certificate Scientists among you need to know 3 common illnesses caused by bacteria and 3 common illnesses caused by viruses for your exam.
