PURE SUBSTANCES AND MIXTURES

A pure substance consists of only one component, it has got specific properties. Examples: gold, water, oxygen.

A mixture is a combination of two or more components.
      -Heterogeneous mixtures: we can see the components. Example: salad.
      -Homogeneous mixture: we can´t see the components. Example: water and sugar.

  • They leant to cultivate plants and raise animals
  • They made products like pottery, cloth and baskets

THE METAL AGES
  • They used metals like: copper, gold, silver, bronze, iron, tin;
  • They used the metals to make jewellery, tools and weapons;
  • They could travel faster with sails;
  • The towns became cities and life was easier.



ANCIENT HISTORY:
 It began with the invention of writing and ended with the fall of the Roman Empire.
-Along large rivers: major civilization developed (Mesopotamia, Egypt, India and China).
-Around the Mediterranean Sea: ancient civilizations developed (Greece and Rome)

Unit 9: Ecosystems

Ecosystems


              PASSWORD GAME!!



Food chain
                        



Types of ecosystems:
1.   Natural ecosystems: develop without human intervention. i.e.: oak forest.
Depending on factors like geographical relief, types of soil and climate we find:
-         Aquatic: fresh water as lakes and salt water as oceans.




-         Terrestrial: the most important factors are light, temperature, humidity and type of soil. i.e.: deciduous forest.

2.   Humanized ecosystem: exist because of human intervention. i.e.: cities, farms…



Changes in ecosystems

Unit 6: Plants

Plant characteristics: They are multicellular, they interact, they don't move around and they make their own food.



Seed plants: Angiosperms and gymnosperms.


Non-seed plants: They produce special cells called spores.

Parts of a plant


Plant nutrition: photosynthesis
