This lesson

• We would like to ask you to watch a documentary about the influence of hormones on your body/daily life
• In SomToday, you will find a file with questions that you have to answer. This will also be the homework for next week.
• The documentary is a bit longer than 45 minutes, so this is also homework.

This lesson

• We will open an assignment in Itslearning where you can hand in the answers to the documentary questions.
• You have until the next lesson to do that.
• Good luck!

Homework

• Finish watching the documentary and answer the questions
• Questions are uploaded in a document on SomToday (in the homework section of this lesson)
• Please hand in your answers in itslearning before the next lesson (check your schedule for when that is, since it has changed!)
