Tuesday 15th March

Message from Mrs. Bonzo:

“Bring in work for your portfolio tomorrow. If we have spare time, we’ll get ready for next week’s student-led conference.”

You guys have done some really good work this year, such as the blood stories, blood drive project, practicals and tests. Why not stick them in? You might even want to print off your blog page and include that – it’ll be interesting to talk about.

OK, time for today’s lesson:

1. Make sure you have finished the task about your group’s experiment. Ask for help if you need it.

2. Complete the tasks below by copying the image to your blog and answering the questions.You can complete them in any order, though it will be easier to start with the one you learned about in yesterday’s lesson.

3. Leave comments on three friends’ blogs (friendly and productive – no name-calling or making fun).

Task A:

6. Name two species which compete with each other for food.

7. Name two species which have no predators in this food web.

-

Task B:(try this if you did station 6 or get bored)

1. What would happen to the rabbits if the foxes disappeared?

2. What would happen to the toads if the predacious insects disappeared?

3. What would happen to the predacious insects if the spiders disappeared (think carefully)?

4. What would happen to the hawks and owls if the foxes and snakes disappeared?

5. What would happen to the foxes if the hawk and owl population increased?

6. Name two species which compete with each other for food.

7. Name two first-order consumers.

8. Name two predators.

OK, get to work!
