this week blog we started doing an experiment in science about forensic but we are learning today so let me tell you about some of the work we have done with group Christian, Lasa, Nikora and me.
Aim:  the aim today is to see what the water-based pen will do with our paper when the water was put on to the cup.

Materials: 

1. plastic cup, 
2. water, 
3. paper 
4. water-based pen.

Steps:

1. The step was to get a paper. 
2. Measure the paper and put a line in 1cm
3. Put two dots with a waterbased pen
4. Put in a cup.
5. Put water in a cup.

Conclusion: what I have learned this lesson was following the steps like getting the paper and lining those up. I also learn that the water-based pen was going up and the colour was spread. I learn that this is about forensics like crime photography .
