y7 challenges for the week 4 - 11 dec

Keep in mind the end of term test is upon us - we will have the test on the 13th of December. For this reason, most of the challenges for this week will be related to revising for the test :)


1. Practice the key words using Memrise:

• energy resources
• particle theory
• solutions

2. Make your own revision materials - be it spider diagrams, newsletter articles, presentations - you can choose the format

3. Make a geode in an egg shell. Geodes are rocks that can be plain on the outside, but have beautiful crystals on the inside. You can easily make geode like structures in egg shells using your knowledge about solutions and evaporation. Here is a tutorial about it:

If you want to take it to the next level, you could try to make an edible geode out of sugar and chocolate:

Super saturated solutions

A super saturated solution is very unstable - even a small shock can trigger the crystallisation of the dissolved substance (as you've already seen during the lesson). This is an example of a super saturated sodium acetate solution.

Y7 Challenges for week 20-27 nov

These are the challenges for the current week:

1. Memrise - The Particle Theory
2. Memrise - Solutions
3. Write a newsletter article for the particle theory topic (or any other revision material: spider diagram, poster etc.)
4. Write a newsletter article for the solutions topic (or any other revision material: spider diagram, poster etc.)

The best articles/revision materials will be used to make a newsletter for the blog and the Facebook page!
