I'm a Detective

Hi everybody for past I believe 1 weeks in reading I have been trying to solve a crime the crime of the muddy foot print my teacher took a photo of a muddy foot print and then we had to solve the crime she also took photos of suspects shoes and we had to compere the shoe print to the shoes and we had a match but we had to be positive if the polices didn't do proper investigation a lot of people who didn't do any crimes would get arrested so happened next was there were 4 markers and a wet bit of paper with some black red and blue on it and what we had to do with the markers was draw a line on a bit of paper and attached it to a pen and put it above a cup of water so the paper was in the water we had to leave them for a minute and see if one of them looked like the first bit of paper my one wasn't the right one in the end we found out Chris did it see ya hope you enjoyed.

DNA

Hi for the past  4 weeks I have been in a reading group a
bout DNA (Deoxyribonucleic acid) DNA is what makes you you if you altered your DNA you could have a tail 3 eyes 4 mouths 5 ears 6 noses 7 hands 8 feet and 9 golden heads so it's a good thing that we have the DNA we have there are a lot of interesting facts about finger prints I have learned  like if you tried to wright out your DNA in genetic code very fast for 8 hours a day it would take 50 years! and the police use finger to solve crimes to they put a type of powder at the surface of the crime scene and then use a special brush and the powder sticks to sweat and oil that is left behind when someone touches a surface then polices use a see threw tape that lifts the fingerprint and now on to the topic of the types of finger prints there are the most common  one's are arch's , loop's and whorl's but some of the more rarer ones are double loop and mixed but I only have loops and arch's like this
