Cells - The Building Blocks of Life. By Shyamala IyerIllustrated by Dr. Biology All living beings are made up of cells. Some of them are made up of only one cell and others have many cells. The adult human body is made up of about 37 trillion cells. WOW, that's a lot of cells. In fact, if you lined up all the cells in a human body end-to-end, you could actually circle the earth more than 2 times. Cells got their name from an Englishman named Robert Hooke in the year 1665. If we are made up of cells what are cells made from? Look around at your house and houses around you. What are the building blocks of a cell like? If you take a look at your home you will notice it is enclosed by outer walls. Sometimes people think of cells as a balloon filled with fluid.

By Meredith Turnbough and Marcella MartosIllustrated by Sabine Deviche and Dr. Biology Legos are a familiar building block that have been used to create an almost unlimited number of shapes.
If you have ever had to get inside a locked car or home you know that shape matters. If you don’t have the right key, you cannot open the door. The shape of the key is important. When you are building with Legos, you have to use the right shape bricks in the right combination to create your totally sweet fort, space shuttle, T-Rex, or whatever else you can imagine building.
