Revision for test

Here is the document that we started using for revision today.

If you understand what each section is asking you about you'll be fine for the test.  Remember that for number two you only need to draw arrows showing how strong the forces are that are acting on the object. 

The object can be stationary (still), moving (constant speed) or getting faster (accelerating).  If the two forces are equal they are balanced, if they're unequal they are unbalanced.  Let me know if you have any questions by coming and seeing me at anytime or by emailing me before Wednesday.  Good luck!

Apologies

Sorry for the break in posts, I've been meaning to put things up for ages.  From what we've covered so far in Alien, you need to know how forces act on rockets on Earth and in Space, what makes up the rest of the Universe and our Solar System (and be able to name different things like planets, galaxies, stars etc.), remember what all living things on Earth are made from (it starts with C, which is also its chemical symbol), and what extremophiles are. 
Here is the extremophiles video we saw in class :

Make sure you remember that extraterrestrials probably don't look like little green men, but are small bacteria like these ones living in extreme conditions.  Conditions on other planets are very different to Earth (temperature, atmosphere, soil/rocks) and we can send landers like the ones we made in class to test what these conditions are.  Make sure that you're up to date with things as we'll be having a short test on this unit next week.

Alien

The topic for this term is going to be 'Alien' for classes with me, and 'Accident and Emergency' for your classes with Mrs. Lynch.  Sorry for the confusion! We will be scouring the Universe and looking for Aliens on other Planets, and learning about them on the way.
