Walt: use our learning process in science experiments about change

we learnt to make a car  with a balloon and paper cups  straws and fizzy bottle top lid first we cut the cup in half  then made two holes in each side for the straws then we put the straws in and put the lids as the tiers then we made a hole in the back for the balloon then we raced the cars on the table and Justice won the race so we had  to give  one point.
