What are Bacteria?
Do you know flagella from fimbriae? The cell wall from the capsule? Step through the animation to learn about bacteria and then test yourself with a quiz.

Bacteria are little animals.
Bacteria are only found in dirty places.
Bacteria are single cell microorganisms and they are found everywhere.
N.B. I am concerned by one statement the animation makes:
“DNA is known as the brain or control centre of the cell because it controls what the cell does.”
Strictly, DNA is a code that controls what (proteins) the cell makes and therefore does. I don’t like the reference to a brain because it is misleading – children might interpret this to mean that bacteria can think. Important that this does not introduce a misconception.
Screen – what it does/how to use it
Click to move through an animation which explains what bacteria are.
Followed by a quiz (with feedback) to test yourself.
- Use in main teaching input to show the structure of cell and bacteria.
- Use for children’s research. Stop at screen showing bacteria – can children explain what the different parts do before clicking on the tabs at the top of the screen to find out?
- Use quiz in plenary to determine knowledge.
