Week 2 challenge
This week we got to see a cool experiment. This experiment showed us how phases can change state. We learnt four different processes: how we change (1) a solid to a liquid, (2) a liquid to a gas, (3) a gas to a liquid, and (4) a liquid back to a solid. Answer to questions below to see how well you understood this week's work.
1. Name the process in which a solid changes to a liquid.
2. Name the process in which a gas turns into a liquid.
3. Name the process in which a liquid changes into a gas.
4. Name the process in which a liquid changes into a solid.
5. Click on the links below. Which process does each link to? Choose from the processes above.
A) B) C)
D)
6. Is GLASS a solid, liquid or gas?
7. Have some fun and attempt to make homemade ice cream!

Week 6 + 7 challenge
This week we started working on our technology projects! How exciting to build a model bridge!
This week I challenge you to find ideas that will make your project stand out from the others. Spend the weekend gathering the most exciting materials to add to your project.
For example:
* leaves for the roof
* coke bottle caps
* straws

Week 5 challenge
This week's focus was looking at the properties of materials. We discussed 10 different properties. We also had lots of fun making up our own Properties Song. Here is this week's challenge:
1. Name the object in each link/picture.
2. Link each picture/video to the most appropriate property from the list in the box below. You may only use each property once.

Week 8 challenge
What a great week we had building our model structures!
This week your challenge is to make the most fantastic mind maps or flash cards that will be used to study from for tests and the November exam. Remember: pictures and colour are important as it makes it much easier to remember! You can even make up rhymes or songs to remember your work. Or you can put words to your favourite tune! Have a blast and GOOD LUCK!

This week we looked at raw and manufactures materials. We will watch exciting video's about how each raw material is made into a product that we use today.
