Another week of engineering. Today the year 7 and 8 students were building a water filter, but first we came in the hall and sat down on the floor, and then the teacher started talking about what we had to do and what we needed to do, and then my teacher asked us if we brought a plastic bottle because that was what we needed for the water filter, but the engineering teacher brought so many plastic bottles, but if there aren’t enough, then we will have to pair up and do it. First we got some scissors and cut the bottle in half, and then we got the top part and flipped it upside down and put it in the bottom, and then my friend got this type of paper and put it in. Then when he put it in, he closed the part where you drink out of with the paper, and then we got this type of sand or rocks, and then we went to Whaea Ellen, and then she put water in the plastic bottle, but mine went wrong because the rocks broke out of place, and then the water got dirty right when we were about to take a photo.
Kia ora, I like how clearly you explained each step of building your water filter so the reader can follow the process easily. Sharing what went wrong at the end also makes your blog feel honest and real.
Why do you think the rocks in your filter moved out of place – was it to do with how they were packed in or the type of materials used? Next time you could add what you might try differently if you built another filter, so readers can see what you learnt from the challenge.
