Today, the third lesson on the topic...
First, we have made predictions about which material would let more water through
These are our predictions.
Finally, we did the VIRTUAL EXPERIMENT, and our predictions were not very accurate. Our only correct prediction was plastic: it does not let any drop through.
In the graphic you can see the comparison between our predictions an the results of the experiment.
What I like most, as a teacher, about this resource, is how easy it is to talk about these topics using the English language in a "real context" and making it possible to use language to speak about difficult content in a significant way.
