Origin of life
According to the Primordial Soup theory, life began in a pool of water, called ‘soup’ because it contained the kinds of chemicals needed to create life. Suddenly something happened – perhaps a bolt of a lightning hit one of the pools – and the chemicals reacted forming more complex molecules.
PART 1: Origin of life theories
- Open a Google Docs with the name: Report_ Origin_Life_G(N)(C).
- Watch the video beside and make the first part of your document, explaining the different theories about the origin of life a mode of introduction.
PART 2: The first cells
Life began at about 3900 Ma ago. The first cell was a prokaryotic cell. It is the simplest organization of living beings and from the Monera Kingdom.
- Now open your Science Bits. Look for the Unit: Formed by cells. Go to Explain part (pages 6 and 7) and extract the information to show the general information about the Monera Kingdom.
- Kingdom:
- Year of origin:
- Characteristics of the prokaryotic cell:
- Parts of the cell:
Include this information in your report.
PART 3: The origin of oxygen in Earth's atmosphere
What do you think about the origin of oxygen in Earth's atmosphere?
A mutation leads bacteria to perform photosynthesis. These tiny organisms are known as cyanobacteria. These microbes conduct photosynthesis: using sunshine, water and carbon dioxide to produce carbohydrates and oxygen...
- Watch this video (it has subtitles, so you can turn them on to understand it better).
- Continue your report explaining:
- The characteristics of cyanobacteria.
- Year of origin.
- Effects of oxygen production.
PART 4: "The first eucaryotic cells and the Kingdom Protista
- Watch this video (it has subtitles, so you can turn them on to understand it better).
- Now open your Science Bits.
- Look for the Unit: Formed by cells. Go to Explain part (page 9) and read it.
- Look for the Unit: The Five-Kingdom System. Go to Explain part (page 5) and read it.
3. Then, finish your report including the information below:
- Characteristics of eucaryotic cells (parts, organelles...).
- Type of eucaryotic cells and differences.
- Characteristics of Kingdom Protista.
- Classification of Protists.
- Add photos (touch them up and apply some effects with Gimp)
- Use Inkscape to create some funny titles.
Conclusion:
Think about the the importance of cells evolution and how it affected to the evolution of the Earth and its layers.
