Hidden fingerprints:

Aim: To learn how to lift hidden fingerprints from an object.

1. Lifting and Gathering fingerprints.

Equipment:

1.   Plastic
2.   Tape
3.   Black Card
4.   Brush
5.   Baby Powder

Method: 

1. Place your finger on the plastic
2. Put your brush in your baby powder
3. Apply the powder on the brush to the plastic
4. Shake of the extra powder
5. Put the tape on top of the fingerprint until you can see it on the tape
6. You then put the tape on the black card 
7. You are then finished

Results:

I did manage to lift a fingerprint but not a clear one.

Not applying to much powder to the plastic.

I think it is helpful because they can scan it and then find out who did the crime.

What Is Filtrtion!!!😀😀😀

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.  Tea Bag
2.   Coffee Filter/Plunger
3.  Swimming Pool
4.  Kidney

Materials

1. Sand

2. Coffe Filter Paper

3. Dirty Water

4. Bottle-2 halfs

5. Pebbles 

6. Cup

7. Sissors

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 in the bottom half of the bottle.

STEP 3

Add layers of filter paper then add your sand and pebbles

STEP 4

Get 1 cup of dirty water.

STEP 5

Pour dirty water into upside down bottle

Measurements

When Mr Palmer did the expirement today the filter that ha was using didn't work proply so the water went down to fast and didn't go clear/clean.

Warning

Make sure that an adult cuts the bottle in half. This water filter is just an experiment and should not be used for drinking water.

Avoid using charcoal briquets, as these can contain chemicals you don't want in your water. Use the activated carbon for water purifiers instead.
