Fizziq//Moss appears on trees, but where?//How to explain that green moss only grows on one side of the tree trunks?//On tree trunks, we find green moss, but did you notice that this foam was often only found on one side of the trunk?//Suggest one or more hypotheses, which you can then test, in relation to the problem posed//In FizziQ, choose one or more sensors that could help you test your hypothesis?//If your hypothesis calls for light, you can use the Luxmeter. If your hypothesis calls for the orientation (north, south, east, west), you can use the Compass//On the side of the tree where the green moss is located, take the measurements using the sensor you have chosen. Record your results in your notebook, for example in the form of a table. Also add a photo//Take the same measurements on the other side of the tree and document your results//Compare all your results and write a sentence that uses “whereas”, in your notebook//In your experience notebook, write a sentence that answers the problem we posed at the very beginning (How to explain that green moss only grows on one side of tree trunks?)
