I use this when teaching theory about cheese. The blank slide is where students find the cards on the making of cheese & write up in their own words. The cards have been shared as a separate resource in TES Resources.
Copy one set for each group of pupils (I usually have 4 per group) Cut out all of the test boxes and then pupils have to create 3 step synthesis routes, including reagents and conditions, as fast as they can. Loads of fun and really shows understanding and gaps in knowledge.
This is for a 100 minute lesson, but there are two tasks which could be split over two 50 min lessons.
The Timeline Poster is one activity and the Darwin text based activity is the second activity.
The text may be too textual for low ability or low reading age students, my low reading age group had an LSA and they were ACE!
