Thursday 25th) with Ceci we used the bunsen burner. These are the steps we followed.

AIM: In this investigation, you will learn the parts of the Bunsen burner and their functions. You will also learn how to use the burner safely in the lab.

Method

  1. Close air-hole
  2. Turn the gas tap and light the burner.
  3. Record the results  ( colour of flame )
  4. Open air hole slowly until it is half-closed open and record results
  5. Open it completely and record results
  6. Place a tripod and gauze on the burner
  7. Place a beaker with 50 ml of water
  8. Heat it with the air hole open
  9. Take the time until the water starts boiling
  10. Change the beaker and water and heat it with the air – hole closed
  11. Take the time until the water boils

This is a video from us using the bunsen burner :

For homework we had to see 3 videos, and make this activity: with Rosario Omodeo :

 

1st video:

 

1-Try writing 3 ideas about each video:

-We draw unspecialised to show features common to most cells.

-The animal and the plant cells have different parts

-In multicellular organisms, cells become specialised to perform particular functions Then,

 

ask yourself 2 questions about the info you´ve seen.

-What is the function of the cell wall?

-What are the specialised cells?

 

Write a metaphor that connects the info shown to your life

– The ribosome is like a construction site because it builds new structures

 

Youtube chanel: oh i get it now!

Created by a GCSE student, for GCSE students

 

2 video:

 

-in the animal cells there are structures such as the nucleus, the cell membrane and the cytoplasm

-The differences between the plant and the animal cells are that the animal cells have a cell wall, a chloroplast and a central vacuole.

-The plant cell has a regular form.

 

ask yourself 2 questions about the info you´ve seen.

-which cell has a regular form?

–Which cell is the one that has a central vacuole?

 

Write a metaphor that connects the info shown to your life

-The cell wall is a gate, it controls what enters and leaves the cell city

3 video:

– Biological systems are composed of many levels

-The cell is inside a tissue.

-An organ system is inside an organism

 

ask yourself 2 questions about the info you´ve seen.

-What is a biome?

-What is an organism?

 

Write a metaphor that connects the info shown to your life

the nucleus is a city hall because it controls the rest of the cell

Last class, with Ceci we watch a video about cells, and then we made this activity all together

Video 1

3 ideas that we got from the video:

1) It is a whole new world to us and scientists have bearly begun to understand it

2) All life is made of cells

3) Cells have different sizes & shapes and can be categorized

2 Questions about the video:

1) When we eat, do we eat cells?

2) What happens to cells when we eat them?

Metaphors:

1) The nucleus is the heart of a cell (Josefina Porretti)

2) Cells are the sturdy branches from which all of us flowers grow

-Literature because the video ressembles a story and we also search for metaphors
