PLANTS NUTRITION (Unit 3 - Natural Science Year 5)

Try to review what we have learnt about plants the last lesson. We are going to use a THINKING ROUTINE: THINK-PAIR-SHARE. Think: three ideas about the last lesson, PAIR: talk about these three ideas to your partner, SHARE: we will talk with all the class so we can create a small mind map about it.


LET'S HAVE A LOOK TO THIS VIDEO TO START WITH THE TOPIC:
  • At the end of the video you have to create a picture in your notebook in which you represent the process of PHOTOSYNTHESIS.



RESPIRATION:
  • Plants breathe.
  • They take oxygen and release carbon dioxide. 
  • It takes place in leave continually, day and night. 

PLANT NUTRITION:
  • Plants are autotrophs: they make their own food.
  • They need sunlight, carbon dioxide, water and mineral from the soil.

WATER AND MINERALS
  • They are importann for plant nutrition.
  • In the soil minerals are dissolved in water.
  • Plants absorved water through the roots.
  • RAW SAP: The nutrients travel up from the stem to the leaves.


PHOTOSYNTHESIS
  • It enables plant to make food using sunligth, carbon dioxide, water and minerals.
  • It takes place in the lives.
  • In the leaves raw sap mix with carbon dioxide and becomes ELABORATED SAP.
  • ELABORATED SAP is the food for the plant.
  • Sunlight is very important for the photosynthesis so it only takes place during the day.
  • During this process the plants release oxygen.

LET'S PRACTICE ALL WHAT YOU HAVE LEARN PLAYING THIS GAME
