Clone a bacteria

?lt;/p>

This experiment's aim is to let you see how a bacteria splits up and makes copies of itself.?Although you won't be able to control the cloning in this experiment, you will have a bunch of bacteria at the end.

?lt;/p>

Caution:

Bacteria cause diseases and can be dangerous!?Throw away the pots and the jelly after the experiment.?Always wash your hands after you've touched the experiment set-up

?lt;/p>

Required equipments:

• ??lt;font size="2"> Jelly mix cubes

• ??lt;font size="2"> 2 yogurt pots

• ? Sterilizing solution e.g.?Dettol

• ? Toothpick

• ? Wrapping films

Procedures:

-??to produce bacteria

1. Sterilize one of the yogurt pots by leaving it to soak in the sterilizing liquid

2. Make up a small amount of jelly, then pour it into the yogurt pot -- not right to the top.?Cover it immediately with the wrapping films.

3. When the jelly has set, peel back a little bit of the wrapping films.?Quickly rub one finger around your gums and teeth and then press it against the jelly.

4. Cover the pot up again and leave it in a warm place to let the bacteria grow

5. Check the jelly every day to see what is growing on it.?Soon, you will see little blobs on the jelly.?These are bacteria from your mouth, and will be cloned by you (if you continue this experiment)

-??to clone the bacteria

1. Sterilize the other yogurt pot.

2. Make up some jelly, pour it into the pot to set and cover it with wrapping film as you did before

3. Sterilize the toothpick

4. Carefully open the pot that has bacteria in and just touch the toothpick into a lump of bacteria.?This should pick up a few bacteria.?Touch the toothpick onto the new jelly and cover it up

5. Leave it in a safe warm place.
