Immune system intro and homework

This video is for your homework this week, as well as asking what vaccinations you've had. We'll be covering this in the next few lessons, so don't worry if you don't understand everything yet.

For an achievement point, explain the difference between specific and non-specific responses in the immune system.  bring this in to be marked on Thursday (double lesson).

Healthy Diet

Today we're going to start looking at what our bodies need to work efficiently and how they get these things from food.  To start with, have a read through the information here and try the test questions at the end.
Once you've finished those, either find your own information or use the links to answer the following questions:

1. Define the word metabolism.
2. Explain why pregnant women usually need to eat differently to women who aren't pregnant.  What benefits does this have for both the mother and baby? 
3. Find out what percentage of the energy in the food you eat each day is used for growth, and what process uses the most energy.
4. Why do we need to eat food?
5. Watch the video on the right.  What food groups is Homer consuming too much of? What is he not getting enough of?  
6. What are two things he could do in order to lose weight?

Physics intro

This website is what we will use throughout the year to work on material from class, as well as homework and revision when you're at home.  Make sure you write the address somewhere (planner, phone, workbook) and save it in your favourites. Once you've done that, answer the following questions in your books -
1. What did you enjoy most about Science last year?
2. What would you like to change or do differently?
3. What would you like to achieve in Science? How can you go about this?
4. Finally, we'll be using this site lots for different things in clas and homework, and there are lots of god resources related to Science on te internet.  See if you can find any games or websites with good information and email them to Mr. Cole.  Here are some I used last year -
