Organic Introduction Quiz Dr Deborah Bunker

Topic Organic Chemistry Quiz Aims Ø This resource has been developed to support learners to develop their Organic Chemistry subject specialist knowledge whilst having a little fun, gaming for learning. The resource can be used to introduce an element of competition between individuals and/or groups which learners appear to enjoy. Level 2, Level 3 Method Power. Point Presentation. This can be used as an Ice Breaker activity to assess prior knowledge. A the start of a lesson provide the Connect to previous sessions learning, providing a fun interactive activity whilst providing checks on learning. This can also be used at the end of a lesson to assess that learning had taken place. Equipment Ø Laptop/Projector Duration >30 Minutes
