I currently teach IGCSE Biology, Chemistry and Physics. Also A level Biology. The resources I produce for my lessons are carefully planned and I try to involve a lot of self-learning to allow students to develop these important skills needed for further education.
A PPT with information regarding the 2 types of fibres. Students collect information about the fibres from around the room (included in PPT) and complete a table stating the differences. They can then use their knowledge to predict the types of fibres found in different animal muscles. There is an exam question and mark scheme to determine understanding of subject material.
I have included the lesson plan I provided when I was observed so feel free to tweak it to suit your group.
