Cells are the building blocks of life. They are smaller than the smallest grain of sand and can only be seen under a microscope. They can have very different shapes. Some stay with you for your whole life, others are constantly being formed. Inside a cell, work goes on day and night. It is a miracle that the countless cells in the body work together perfectly without you having to do anything, or even think about it.
With building blocks, although much larger than the building blocks of life, we can build an incredible number of different things. Take a look at what we have built and guess which bible story it represents.
