This year is my first year teaching IB Biology. The InThinking Biology site has proven to be immensely valuable to the quality and delivery of my lessons.

These InThinking Biology activities are excellent! I was looking for something to break the monotony of a cells lesson so I tried the Cell types detective activity. Students loved it. Both the situation and the examples were brilliant
