Revision video

I know that we've finished the patterns of reactivity section, but I found this and thought it might be useful revision for any tests that we might have coming up (hint!).  We'll talk about it in class and have time for revision, but in the meantime watching this might help you:

Here is the link for the start of the space and gravity unit we did today:

I'm not sure why the last slide doesn't read properly, it was meant to be the table of the differences between mass and weight.  If you can't remember these, look back through the earlier slides to help you with definitions.

This is the link for the Patterns of Reactivity topic we started today, so make sure you understand what was covered.  I also included some more questions for a Year 8 class, so taking a look at them would be useful too (on the second slide).

Metals

As we talked about we've finished the unit on Plants for Food, and will be starting on a new Unit looking at patterns of reactivity tomorrow.  Try and remember to bring your planners to class as we will be using the periodic table in the back, and if you have any spare time try and learn the symbols of some metals you have heard of (copper, metal, magnesium, iron, sodium, potassium)

This is the video that we watched during the pesticides lesson last week.  It may be useful for your leaflets, and remember that DDT is a good example of a pesticide being dangerous to many other organisms aside from pests.

This is the link to the powerpoint we used to make our leaflets on pesticides today: https://docs.google.com/viewer?a=v&pid=explorer&chrome=true&srcid=0BzFUvVu_WNI_ZGIzZGJkMGQtYzhjNy00YjU2LTliOGYtNDljYjZjMjVkOTFk&hl=en
You should keep your finished leaflets in your book as they will be useful for revision.

Week 8

Welcome back, here is the link to the video we watched in class today.  Remember that we need to know what the plants get from the insects, and the other way that they can absorb this material.
If you have time, do some research to find out what plants need phosphorus and potassium for.  We will also be looking at fertilisers and pesticides in more detail later this week, so defining them would be useful as well.
