Straw Rafts

In Inquiry wen are learning about design process. The design process is where you Plan, Design and test a product or theory. Sometimes when you test it, it doesn't work and you have to start at the beginning again to see how you would make it better. Mrs McG gave us a challenge. We had to plan, design+Build a straw raft to float with 40g of weight on it. We could only use 20 long pieces of straw and a long strip of tape. Our raft failed round about 1 times because it was not leanthed out enough. We did some research about how rafts float and found that Object that a less than water. we found trying to stick it together challenging because it just keeped on moving up and down and it was annoying. Heres Mine I hope you like it. 

BirdFeeder!

(STEM Technology)

This term in S.T.E.M we have been learning about Bird feeders.

First we design then we did the planning the materials and building. Last we did the building.

I found building it very challenging because we didn't start to agree on stuff.

I found designing enjoyable because it was very fun to add in some extra on it.
