Time Line Project


TIME LINE PROJECT (assignment outline)




Optional: Explore Human Evolution

Go through the following websites and take notes to improve your understanding of the evolution of humans.


INTERACTIVE:
Human Evolution over time.
Human Evolution Interactive

What period of time did Humans evolve over?  How did climate fluctuate? How many homo species do we know about?


IMAGE:
Lucy: The crucial 'missing link' fossil between 4 legged primates and bipedal primates
An image of the fossils of 'Lucy' Australopithecus afarensis

This image reflects ALL the fossils we currently have of Australopithecus afarensis.  What questions or comments do you have about it? 

VIDEOS & INTERACTIVE:
Big History: Human Evolution
Big History (chapter and videos)

What does this website outline as the important stages of human evolution?

INFORMATION:
Walking Upright: Some of the evolutionary mechanisms
Walking Upright Mechanisms

What was required for primates to walk upright?  Over what period of time did this occur?


INTERACTIVe
Compare the mystery skull to other known homid skulls:
Mystery Skull Interactive

How many hominids were there? What features of the skull do Scientists use to understand them?

TEST: Photosynthesis & Respiration Wednesday 15th

On Wednesday 15th August you will be having a test:

The test will have three sections:
1. Multiple Choice Section
2. Short answer questions (about a short paragraph of writing required)
3. Analysis of a photosynthesis or respiration experiment (like one we've done in class).

----
The types of questions being asked will be:
- What is photosynthesis and respiration: What are the reactants and products of each>
Watch: Bozeman Photosynthesis  
Try looking at BBC Bitesize: Carbon Dioxide and Respiration 

- Why is photosynthesis important? How has/does photosynthesis effected the planet?  SHORT ANSWER
Try looking at this TED ED video or Cambrian (early animal) Explosion wiki  or watch: Photosynthesis and Global Climate

- Where does photosynthesis and respiration occur?
Watch this interaction: Photosynthesis Interactive  and Respiration Interactive

- What is the similarities and differences of respiration/photosynthesis?

Also there will be questions about:
- Reading the periodic table and understanding proton, neutron and electron count from it
Watch: How to read the periodic table (also notes on the power-point below)

- Reading a chemical equation and understanding its notation (numbers and letters)
Watch Writing and Reading a Chemical Equation (also notes on the power-point below).

- Conservation of mass principle and how it is applied to chemical reactions (like photosynthesis and respiration)
Look at this: Conservation of Mass and Chemical Reactions

Also there will be questions about:
- Your assignment - volcanoes and how first life formed (multiple choice)
-  Snowball Earth: How it started, its impact on life, and how it finished SHORT ANSWER
If you have completed the assignment and looked at the resources there, you should be fine to answer these questions.  Look at the assignment link below for more help.

Experiment Question:
This question will get you to analyse the results of an experiment and answer some questions in relation to photosynthesis and respiration.   To prepare for this question you should have a thorough understanding of these two chemical reactions and have a think about some of the experiments we have done in class: Finding starch in leaves and testing acidity of algal balls.
