PBL challenges!

Hi my name is Dejon and I am going to talk about about my PBL. So the teachers gave us 3 challenges And my hub had to do them. 

The first challenge was a balloon challenge. What we had to do is make a devise that could get a balloon from three meters away. The materials we had was paper 1 meter of tape and 6 meters of string. my class got into groups of 4. My group made a ball made out out newspaper and some tape on it to stick the balloon and bring it back. we have five terns to try and get the balloon but it did not work.

The next challenge was we had to make paper close. The materials we had was 6 news paper and 2 meters of tape. But my group did not do well because when I got my close ready it ripped so and the rest of my group also did't go well.

The last challenge was called marble log. For marble log you have to make a devise that can get the marble 3 meters away. Therese a can and you have to try and aim then you have to try to make the marble hit the can or pass the line. If you hit the can you get 5 points and if you pass the line you get 3 points. My team did't get any points because the mane devise didn't work because it toke to long. Then one person from my team started to make a backup devise but there was not much time left so it did't work.

So what do you do for PBL. Maybe you should blog about it.
