MY PICS .  In this edible lab I did a representation of the earth by only using a Hershey bar,marshmallow fluff ,graham cracker and a chocolate ball. For the first layer ,the crust, I used a graham cracker, marshmallow fluff and crumbs of a cracker to represent how rocky this layer is. As the mantle I used a graham cracker,Hershey bar, and marshmallow fluff. The Hershey bar represents that the rock hasn't melted yet. For the outer mantle the I used the graham cracker a Hershey bar and marshmallow fluff. This time the hershey bar is mushed to make it look like it was melted rock. For the last layer ,the inner core, I used the chocolate ball, Hershey bar, marshmallow fluff,and pieces of a cracker and rolled it all into a ball so it could look as if it were all melted.  In this activity we used a simple Milkey Way bar.We had to whats the difference between divergent boundaries, convergent bounderies, and transform boundaries using a Milkey Way bar.When I mushed up the hershey bar it created a something that looked like a mountain which is called convergent boundaries.When I took the bar apart it was like divergent boundaries .When they go past each other they are called transform boundaries.

What i learned this week in Science was about outer space and that there are comets and asteroids. I also learned that all the planets revolve around the Sun, and that it takes 23 hours and 56 minutes to make one whole day.Revolution and rotation are the 2 movements that the Earth makes, and the reason that there is leap year is because at the end of each year there is 1/4 left and it takes 4 whole years to make 1 day. And that day is adding one more day to February.
