When studying about bacteria in biology, one of my sons decided to build a Lego bacteria. He used two small base plates, which he connected with black Legos representing the cell wall. Green Legos projected out of the cell wall, representing the pili used for locomotion. The flagellum is made of green Legos, and it looks like a tail coming out of the back of the bacterium. The flagellum is also used for locomotion.
The ribosomes are red Legos, and they synthesize protein in the cell. The ribosomes are what powers the bacterium because they take the DNA and turn it into protein for the cell to use. The DNA is made out of blue Legos arranged in a squiggly pattern. Without DNA, the cell would die very quickly because the ribosomes would not be able to make any protein.
Many bacteria are harmful to humans, but other bacteria help humans. People who study bacteria help us to stay healthy, which is one reason why my son wants to be a microbiologist.
If you enjoyed making Lego bacteria, you will love the biology activities in the Unit Study Treasure Vault. If you are homeschooling, your whole family can enjoy biology through the videos and activity demonstrations in the biology section of the Vault!Tweet
