Maths - KS3 Topics and chapters

Good news is I only have 20 more days work of maths to complete my maths KS3 text book.  THen I will be complete for Year 9/S2 maths!!!

We did a summary in MS Excel.

       

Science: Chemistry

Today I did these things on the KS3 BBC Bitesize website.  http://www.bbc.co.uk/schools/ks3bitesize/science/chemical_material_behaviour/

Chemical and material behaviour

1. The Particle Model
2. Behavior of Matter
3. Atoms & Elements
4. Compounds & Mixtures
5. Acids, Bases & Metals

Maths KS3

We have been concentrating on maths for the past few days.  We have been through:

Decimals
Adding, subtraction - the general rule is to proceed as normal or remove decimals and then reinsert the decimals at the end.
Multiplying - remove decimals, work out and then combine the number of decimals points in the answer.
Division - make a whole number by multiplying by 10 or 100 and then do long division.  The answer will be the same as if you had not multiplied by 10 or 100.
make it a whole number

Factors
Factors of  10 are 2 x 5.  Factors of 20 are 2 x 10 + 2 x 2 x 5  = 2squared x 5.

Prime numbers
Prime numbers only have 2 factors - 1 and themselves.
2,3,5,7,11,13,17 etc. 2 s the only even prime number.  To work out if it is a prime number:  is it divisable by 2,3,5,7?    If not then its a prime number.

HCF
Take the lowest factors (all of them) and work out.
LCM
Take the higests common factors (all of them) and work out

Science Revision

We are doing a quick recap of Science done end last year.  I am starting with KS3 so wanted to make sure the KS2 was well cemented in my mind.

I went through most of the book today and have a couple of chapters of Revision for tomorrow.

Today I went through:

1. Looking at living things
2. Plants
3. Living things in their environment
4. The human body
5. Variation and Classification
6. Looking at materials
7. Changing Materials
8. Seperating Mixtures of materials
   
   
   Tomorrow I will also do a couple of experiments.
   
   
   A bit of a pain i.e.irritating thing is that I just heard that a Science group came out to visit the local school.  Unfort the school did not let me know so I missed it.
   
   We did ask them to let us know of any special events where I can join in and they agreed to it but seems like they are not bothered ;(   Never mind.  I do loads of experiments at home he he
