Thinking Allowed

final exam by dcJohn on flickr

One week and counting…. your semester 1 Integrated Science exam is on Tuesday 24th November.  Make sure you check the exam schedule CAREFULLY so that you report in the right place at the right time.

You will need to bring pens, pencils, ruler, eraser and calculator to the exam.  YOU ARE NOT ALLOWED TO BORROW.

Here is a comprehensive checklist to use for review.  Thanks to Mr Duckworth for producing it. 

Grade 9 Integrated Science Learning Outcomes revision sheet

Cell structure and processes review site.

On this document you will find a list of interactive review sites.  Thanks to Mr Hobbins for putting it together. G9 Semester 1 review websites

Take some time to click through this site to learn more about cells and their structures. 

Here is another good place to learn about cells. 

Look through each site and then leave me a comment as to which of them you preferred and WHY. 

If you find any other sites on this topic that you think would help your classmates learn, please include them in the comments too.

Here are a couple of useful websites to cover topics 6.3 and 11.1 on the immune system.

The Biology Project has problem sets, tutorials, resources and interactive activities.  I particularly like the HIV/AIDS simulation one.

The Cells Alive site has a number of useful links and animations.  Click on the immunology tab on the left hand side and go from there.

Many of you found today’s lesson challenging.  That’s ok!  Keep practising and you will become more confident in writing formulae, naming compounds and balancing equations.  Nobody said it was easy!

Here are some links to try:-

Lewis structures, also known as dot and cross diagrams, represent the arrangement of valence electrons in elements and compounds.  This site has a detailed explanation of how to draw them.

These sites are ones we will use in class to practice.  Feel free to practice at home too

Here are some good sites for information about dihybrid crosses.  There are also lots of practice problems to try.  We will use these in class on Tuesday.

1. This site has a lot of clear information and activities.  A good starting point.

2.  This site has several problems for you to work through with nice hints to help if you get stuck.

3.  The Biology Project from the University of Arizona is always worth a look, although it is quite advanced.
