Class Event #2

During science class we learned about Chromosomes and how they determine your height, weight, gender, hair and much more. There are 23 chromosomes in each sex cell that you get from your parents, 23 chromosomes in the sperm and 23 chromosomes in the egg. After fertilization there are 46 chromosomes in each body cell.

Current Event #3:

The ozone layer is depleting before our eyes and it is all because of us. The ozone layer resides within the stratosphere. Ozone is a colorless, irritating gas that smells something like a burning spark plug. Our ozone layer has a gaping hole in it because of all the pollution leaving man-made factories. The ozone layer is depleting because of humans. We are also the cause of sun spots and extremely dry climates. If you have an idea to try and stop the ozone layer from being destroyed completely, then leave a comment.

Class Events #1:

In science class we are learning about extracting D.N.A. We extracted D.N.A. from strawberry juice, pea juice, and onion juice. I learned that D.N.A. looks like a slimy piece of hair. We also learned that the make up of your D.N.A. even determines the color of your hair.

Current Events #2:

A whole bundle of new species are being discovered in New Guine's Foja Mountains. A team of crack scientists are searching the area around the mountains. They have a species that they find very interesting. It is a new species called the Golden-mantled Tree Kangaroo or (Dendrolagus pulcherrimus). The scientists are baffled at what else they have discovered along with this tree kangaroo.
