Product Description
This 14-slide powerpoint presentation covers 'Topic 4.2 - Energy Flow' 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 two sections:

     • A - Food Chains
     • B - Energy Loss

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: Most ecosystems rely on a supply of energy from sunlight.
U2: Light energy is converted to chemical energy in carbon compounds by photosynthesis.
U3: Chemical energy in carbon compounds flows through food chains by means of feeding.
U4: Energy released from carbon compounds by respiration is used in living organisms and converted to heat.
U5: Living organisms cannot convert heat to other forms of energy.
U6: Heat is lost from ecosystems.
U7: Energy losses between trophic levels restrict the length of food chains and the biomass of higher trophic levels.
S1: Quantitative representations of energy flow using pyramids of energy.
