Evergreen


Find three examples of each:

Evergreen: 
1. Pine tree 
2. Magnolia
3. Pohutokawa  

Deciduous;
1. Plum tree 
2. Maple
3. Oak silver bush

Science (Dirty Water Experiment)

Aim: To make a filtration plant using household materials.

Water Filtration Plant

What is filtration?


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

Examples are:

  1.  Water filterer
  2.  Swimming pool 
  3.  Bath tub full of water
  4. Sink full of water

Materials

1. One recyclable plastic bottle 
2. Pebbles
3. Sand
4. Filter paper
5. Dirty water
6. Plastic cup
7. Scissors

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


Step 1

Cut the bottle into half.

Step 2

Put the top half upside down then place it inside the lower half.

STEP 3

Add layers of sand and pebbles.

STEP 4

Get 1 cup of dirty water.

STEP 5

Pour dirty water into your filterer.

Findings

Write a short sentence about the water every 1 minute. 
Include 'How much water has filtered through', 'How fast it is dripping through', and 'How clear the water is'.

Minutes                          1.                         2.                   3.                    4.                       5.
Drops per minute:         6                          5                    3                      5                        6
Water colour: Yellow
Conclusion:
Now we know that if dirty water comes through pebbles, sand and filter paper it becomes clear and changes it's colour as well. Now we know the steps and how much minute per drops it can do. You can try this out and see what will your dirty water changes into.
