20 Jun STEM Challenge
Mexico class went to Heartlands High School to complete a STEM challenge. The STEM challenge was to create a filtration system to help us survive on a stranded desert island. We used a variety of materials such as cloth, a plastic bottle, carbon and pebbles. When we poured dirty water through our filtration system, we learned that the cloth was able to separate the big chunks of debris. The water that passed through was a light yellow. Finally, the last step to help eliminate bacteria was to boil it.
