 Growing Bacteria

What you need:

Agar jelly

Petri dish

Cotton buds

Dirty surface 

tape

Method:

First, you need to make the agar jelly.

Then, you pour it into the petri dish.

After that, you need to put the petri dish in the fridge to set.

Next, you wipe your cotton dud on the dirty surface. Then, you wipe it on the 

Agar in the petri dish.

Finally, seal the petri dish with tape and wait for your bacteria to grow.

Last Tuesday we all had a look at our petri dish and some of the bacteria  did  grow and some Didn't and some bacteria was fluffy and some were green and yellow and black and white mine did not grow so i have no idea what mine looked like But here are some of the bacteria that some people grew.

Skatebording Sphero

I worked with Teri and Bella-Rose.  The challenge was to make a ramp and try to make the Sphero fly the longest distance.  

We made a ramp out of cardboard and tape  if we made the ramp too steep the Sphero would not jump the ramp.  We did not make our ramp steep. It took a while for the Sphero to fly because we kept missing the ramp.  Then we programmed the Sphero to roll straight and fast.  Our Sphero travelled 100 cm.
