Lesson 1 – Mrs Gren

My dominant emotion: Neutral

Screenshot/Photo of what I learnt:

How it would help me in the future: In general it would allow me to understand topics related to the natural process of organisms much more easily, whether in the classroom or outside the classroom.

Lesson 2 – How bigs is a cell?

What I found difficult: Getting the microscope to focus onto the cell was very difficult, especially the higher zoom levels lots of precision is required in order to gain focus.

1 Fact I did not know 1 hour ago: Each individual cell is rectangular shaped and had a spot which is the nucleus.

Lesson 3 – ‘Plant v Animal Cells’

Lesson 4 – Labelling a plant cell

One thing I already knew: I already knew most of the basic anatomy of a plant cell such as the cell wall, cell membrane and chloroplast as I have learned about it before at school.

Lesson 5 – Diffusion

2 important keywords: Concentration, Movement

2 ares in the human body where diffusion may be important: Diffusion happened in the lungs to carbon dioxide and oxygen, and in the kidney diffusion happens to water and salts

Lesson 6 – Osmosis

1. Order of activities and which: All, in order of the presentation
2. The animations, although simple and plain, they gave clarity to my understanding of the process of osmosis
3. Ratings: Focus – 5, Learning – 4, Time-Keeping – 5

Lesson 7 – Plasmolysis

Process of osmosis in a plant: Osmosis is essential to plants and specifically the roots, the roots of a plant are hypertonic compared to the soil, therefore it allows water to move from the soil to the roots, the roots then use osmosis to transfer the water to the stem and the rest of its body.

What was difficult: Using the correct term (hypertonic or hypotonic) was difficult as they are very similar both spelling an pronunciation, causing me to mix them up.

As we can see above in the container in the left, the left side of it has a greater concentration of water molecules (red dots) compared to the right side, because of this it is a hypotonic solution, therefore water will transfer from the left side, through the semi-permeable membrane and into the right side. Balancing out the water gradient as seen in the container on the right.
