1. DNA.
2. Fingerprint.
3. Clothes.
4. Footprints.

Fingerprints

Fingerprint characteristics

Aim: To look at the different types of fingerprints.

Materials:

1.  Inkpad
2.  Balloon
3.  Fingers

Steps      

1. Roll two fingers  on top of the ink pad
2. Place your finger on top of the balloon
3. Blow the balloon and then look at your amazing fingerprint

Ink prints

Thumbprint	Index fingerprint
It may be hard to see but that thumbprint is a Double loop of Niko’s : )	This is the Index finger of Lasa’s A Loop.

Record the types of fingerprints from those in your group.

Name	Fingerprint 1 (Thumb)	Fingerprint 2 (index finger)
Lasa	Loop	Loop
Niko	Double loop	Loop
Ryan	Loop	Loop

Questions:

Do people always have the same type of fingerprint on their thumb and index finger?

I do not think that we do and that is just my opinion,

What was the most common type of fingerprint in your group?

Loop Was the most common,

Dusting fingerprints:

Lifting fingerprints

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

1. Lifting and Gathering fingerprints.

Equipment:

1. Fine brush
2. Powder
3. Plastic
4. Black paper

Method:

1. Place your index finger and thumb on to the powder,
2. Use the brush to identify the fingerprint with the powder,
3. Put tape on the fingerprint that you made on the powder,
4. Place the tape on the black piece of paper.

Conclusion:

In this conclusion, I & my group of Ryan & Lasa had lots of fun doing
this task/activity and we learned that if someone were to rob us or try to
take something we would be able to identify who the would be, I found out
that there were many different ways to find fingerprints.
