    (Spanish school responsable)

     

    How much water do we waste when brushing our teeth?

    The 3 schools are going to work in the challenge. We are going to share with a video the process of solving the challenge.

    Then we are going to compare the results with graphics in our collaborative blog and the school that waste less water is going to give advise the others how they could save water.
