  • Topic 2 - Molecular biology revision activities

A single page revision summary of the molecular biology SL topic.

If you want to see the all the different aspects of this topic on a single A4 sheet this page will help you. By completing short questions or cloze activities students are forced to review the whole topic and complete an overview of the main concepts in the topic.

It helps students to identify areas in need of extra revision and gives less confident students a useful set of facts to learn.

Description

Activity 1

Brainstorm the topic using the graphic below of key words which may help to bring out the key ideas.

Activity 2 - Revision summary sheet

Complete the A3 revision worksheet containing unfinished phrases, and missing words about the topic.
You should use your lesson notes, and your text book to help you. Avoid looking on the internet as the answers you might find may not fulfill IB criteria in IB exams.

Activity 3 - Check and improve your answers

Compare your answers with a friend or the model answers

Make improvements to your answers and note the areas which require further revision.

Activity 4 - Hot Seat Challenge

Students set their own challenge to try to memorize parts of the sheet.
Students can begin using look cover test check for 5 points at a time, and gradually build up until they can remember the whole sheet.

When a student is chosen for the 'Hot Seat' they sit in the teachers chair, describe their area of expertise (ie. how much of the sheet they think they know) and other students ask them as many questions as possible in one minute.

Teachers notes

This activity is aimed at those students who need help to make their revision effective, but it is useful for all students. The three short activities are really just suggestions.
The worksheet could be a simple homework task.

Suggested lesson plan.

Activity 1 (10 minutes)

Brainstorm the topic asking students to recall as many parts of the topic as they can.
Record these on the whiteboard.

Activity 2 & 3 (30 minutes)

Students use their text books and notes to complete the unfinished phraes on the worksheet.
Students compare their answers to the model answers provided.

Plenary activity 4 (20 minutes)

Hot seat challenge - combined with memorizing activity

Extension work

There are many possibilities for extension. Students could

  • create a mind map of the topic
  • produce lists of questions for the hot seat challenge
  • make a revision presentation on one part of the topic

The teacher could write down the questions from the hot seat challenge and use these in a "Line Dialogue Activity."

In a line dialogue students form two lines facing one another other. Everyone has a copy of the Hot Seat question list. To begin, line A students simultaneously ask a question to the person opposite.
After 2 minutes, students in Line A move one person to the right (the last person should move to the beginning of the line.) Then students in Line B ask questions from the list questions. Students repeat the process alternately asking the questions.
