Materials:
1. Petrie dish

2. skittles

3. water 

 
Process:
Step 1: put the skittles in the petrie dish

Step 2:then add water

Findings: What happened was when we put the water into the petire dish and the colours came off the skittles.

Reflection: i have learnt that if you put water with skittles the colours

What did the colors do? The colors came off and made like slices of pie with each colours
Did the colors mix together? The colors did not mix together they stayed in the pie slice
Why not? what i think is that the colors did not mix because they had different chemicals in them and would not mix.

When we have a reliever:

Today with our reliever I started off fine and then I wanted to sit with my friends. And listened to music. When we have guests in our class I should act the same when the teacher is teaching. And treat them with respect. Next time I will behave and stay at my seat. And not listen to music.

My past in drama

In my past week we have been learning about healthy food. On Tuesday we watched a video of what takeaways look like in their photo compared to real life. Today we said a phrase of healthy food I did eat well stay swell. And when I said my phrase I had to think about my position on stage and how I said it.

do you know how to make your own filter

What is filtration?

Filtration is separating solids from liquids by adding a medium through which only the liquid can pass. 

Examples are:

1.  a tea bag is a filter 
2.  coffee uses a filter
3.  a pool has a filter
4. your kidneys

Materials

1. dirty water

2. bottle split

3. sand

4. pebbles

5. filter paper

6. scissors

7. cup

8. funnel

Process - ( use verbs or doing words in each step )

Step 1

Cut the bottle in half.

Step 2

Put the top half upside down inside the bottle bottom. 

STEP 3

Add layers of filter paper and add sand and pebbles.

STEP 4

Get 1 cup of dirty water.

STEP 5

Pour dirty water into the upside down bottle.

When I did my one we did it all correct but it dd not work it was still dirty. I think it did not work because we only put one layer of filter paper.
