8. Assign students to do Exercise 6.1 from the Student’s Book.
Mark the exercise and provide feedback.

6.2 Gas exchange in plants

Teaching steps

simulations of gas exchange in plants. Ask them to describe
what they have observed.
2. Use Activity 6.2 from the Student’s Book to guide students to
observe stomata on a plant leaf.

Safety precaution

Be careful when working with sharp objects, such as a needle,
surgical or razor blade.

6.3 Respiration
Teaching steps
1. Guide students to search for information from internet sources
and prepare short notes about respiratory substrates and their
energy value.
2. Guide students to search from internet sources the simulations
of the glycolysis process. Ask them to describe what they have
observed.
