Einstieg (15 min) - Partnerarbeit

– Abbildungen mit Optimalen Wachstumsbedingungen zweier Pflanzen
– Partner A: Describe the graph to your partner. (Use your „working with graphs“ vocab sheet)
– Partner B: Describe a problem that arises when these two plants grow in the same region.
– Herausarbeiten des Problems
– EW: have the same needs, need the same resources
– Exactly. So, what do you think will happen with the 2 species when the grow in the same region?
1. Form a hypothesis.
2. Compare your hypothesis with a partner. If necessary, adapt your hypothesis.
3. Share your hypothesis in class.
Verschriftlichung der Hypothesen an der Tafel
– Puffer: Abstimmung über die Hypothesen
– Überleitung: We as scientists check our hypothesis usually by experimenting. However, an experiment with growing plants would take a long time, so you will receive data of studies that have been done and you are going to analyze the data.
