Conclusion Questions:

Today in science we did a fingerprint with ink and white powder experiment. 

(Ink Pads)- We have been finding out what type of fingerprints we have and I found out today that me and my buddy have the same fingerprint but on different fingers. We both got a loop and what we used to find out our fingerprints was from a ink pad.

(White powder)- We had to find out what type of fingerprint we have in the white powder. The white powder was really mess but we ended up making a really good fingerprints. Me and my buddy didn't have the same fingerprints this time. 

Hope you enjoy and I will be posting all of these kind of blog post. 

What could you do to improve your results next time?- I could impove our fingerprints because we couldn't really see what type of fingerprints we have.

Why do you think fingerprints are useful to crime scene investigators?- So the investigators can go find the person who was guilty for there situations.
