Experiencing Concrete

We are learning how to Experience concrete and by making concrete with other ingredients.
I found it hard by getting all the ingredients and putting the right ingredients in.
Next time I would like to experience more things about concrete.

Modifying images

I learnt to modify and change images using poly line and call outs. I found tricky to sty in the lines. Next time I would like to be more focused on the lines/polylines.
