Product Description
This 34-slide Powerpoint presentation covers 'Topic 5.2 - Natural Selection' in the 2016 IB Biology curriculum. Each slide includes the specific learning objective as well as key vocabulary that students should note.

The topic has been divided into three sections:

     • A - Natural Selection & Variation
     • B - Adaptations & Competition
     • C - Evolution Examples

The presentation itself contains minimal information as it is intended to be used with teacher guidance. There are sometimes 'Video' throughout which link to relevant and informative YouTube content. The slides are formatted to be visually pleasing and to also print well for handouts or revision. Please see the preview file (first 8 slides) for an idea of the aesthetic and level of detail in the presentation. The relevant 'Essential Knowledge' can be found below.

Suggested Use:

I have had success using these presentations to review topics after students have been exposed to the material at home. I typically have the class read relevant material (book, site, etc.) and then watch the videos the day before introducing a topic. During the class period, I use the slides to structure the discussion around the IB Bio Understandings. The remaining class time is spent reinforcing the knowledge or working on activities, written test practice, or nature of science.

**These presentations are based on the IB Biology Course Guide and do not follow any textbook

As always, please let me know if you have any suggestions for improvements. These are always a work in progress!

==============================

Learning Objectives:

U1: Natural selection can only occur if there is variation among members of the same species.
U2: Mutation, meiosis and sexual reproduction cause variation between individuals in a species.
U3: Adaptations are characteristics that make an individual suited to its environment and way of life.
U4: Species tend to produce more offspring than the environment can support.
U5: Individuals that are better adapted tend to survive and produce more offspring while the less well adapted tend to die or produce fewer offspring.
U6: Individuals that reproduce pass on characteristics to their offspring.
U7: Natural selection increases the frequency of characteristics that make individuals better adapted and decreases the frequency of other characteristics leading to changes within the species.
A1: Changes in beaks of finches on Daphne Major.
A2: Evolution of antibiotic resistance in bacteria.
