In our Language class we were assigned to do a new booktube about the Lending Library that we choose. Here is my booktube about the book “Impulse” written by Catherine Caulter. Hope you enjoy it!
In our class of Biology we have been studying the gas exchange. After learning some its characteristics, we have made a chart. Here it is.
|Inspired Air||Expired Air|
|Oxygen||21%||16%||Respiration (Raw materials)|
|Carbon Dioxide||0.04%||4%||Respiration (Waste products)|
|Depends on the environment or atmosphere|
|Dust||Variable||Few, or no dust||Ciliated cells|
In our biology class we have studied the “Cellular Respiration” and its functions. Here is an activity that our teacher told us to make in pairs. I work wit Juan Lutowicz.
1 – State the uses of energy in our body.
- It contracts the muscles, so we can move our parts of the body;
- It is used in reactions that produce different molecules;
- It is used to build up larger molecules from smaller ones;
- It is used to transmit nerves impulses.
2 – Construct a mind map about respiration. You may do it on a sheet of paper or use any of the tools available such as bubble.us
You should include:
b- Types: Aerobic and anaerobic (in muscles and yeast);
c- Equation in words;
d- Amount of energy released
3 – Explain the meaning of “oxygen debt”
Anaerobic respiration produces an “Oxygen debt”. This is the amount of oxygen needed to oxidise lactic acid to carbon dioxide and water. The existence of an oxygen debt explains why we continue to breathe deeply and quickly for a while after exercise.
4- Search in the internet a short video, which explains why the breathing rate does not return to normal immediately after vigorous exercise stops.
