lesson 1:

1 word describing your dominant emotion in the lesson.

interested. I was interested because of all the new information on what I researched throughout the lesson.

1 photo that might summarise something you learned in the lesson

1 thing that this learning point might relate to anything in your future life. (doesn’t have to be science)

this information I learned can influence how I think about the way things around me work and move.

 

Lesson 2:

Cell photo (onion) 

a practical skill I found difficult. 

Getting the microscope in focus and for us to get the cells in the best photo.

New knowledge 

I found out that an onion skin is a good way to find and explore the cells of a substance.

One question that was not answered. 

Why is it just the onion skin, not the rest of the onion?

 

Lesson 3:

Cell photo (plant)

Cell photo (cheek)

To figure the length of one cell, divide the number of cells that cross the diameter of the field of view into the diameter of the field of view. For example, if the diameter of the field is 5 mm and you estimate that 50 cells laid end to end would cross the diameter, then 5 mm/50 cells = 0.1mm/cell.

 

Lesson 4:

one thing I already knew.

That both plants and animals have cells which contain a nucleus.

Mesophyll cell. 

one thing that might be difficult with the content of this lesson. 

Remembering all the different organelles of each human and plant cells and knowing how to label the cells.

How can I work on this?

I can regularly revise and practice this task so this knowledge sticks with me.

 

Lesson 5: 

Diffusion

two keywords.

• diffusion
• semi-permeable membrane

• diffusion of oxygen and carbon dioxide occurs in the lungs
• diffusion of water, salts and also waste products occurs in the kidneys.

 

Lesson 6:

Osmosis.

List of tasks.

• video
• read (booklet)
• play games
• test

I thought the videos and the test were most useful to me because the video explained the lesson well and gave me the information and the test gave me a feel of what type of questions I need to work on.

Ratings. (out of five)

a. focus = 4

b. learning = 4

c. timekeeping = 4

 

Lesson 7: plasmolysis 

Plants gain water through their roots through the process of osmosis.

since the soil has a high concentration of water, the water travels into the roots until they both have the same amount of concentration of water. however, the plant brings the water up, which was transferred into the roots and into the plant, therefore the plant keeps receiving water, due to the constant low concentration of water in the roots.

Something to remember:

Hypotonic solution

• high concentration of water
• low concentration of solutes

Hypertonic solution

• high concentration of solutes
• low concentration of water

Lesson 8: revision 

The picture shown on the slide is a skin cell.

I know this because of:

• the young to old scale
• the dead skin cells that are shown.

During the first week of grade 9, I meet new people and I learnt new things about the current stage of grade 9 and the more things I will learn and the new experiences I will have in the future. For Monday and Friday of the first week, we were off schedule, so we could bond and learn more about our mentor class. On Monday, we would meet our new mentor class and our teacher. We also had assemblies to welcome and congratulate us into high school. Through Tuesday to Thursday, we would have our normal subjects. This introduced us to the different people in those classes and also those new teachers. On Friday, we had an assembly talking about what future trips we could choose to go on. We then went to the sports hall to participate in team building activities and challenges with our mentor class. I felt like these activities really let us get to know each other. We finally went back to our mentor classroom to start on this portfolio. For the future trips that we will be able to choose, I am excited to see what new friends I will make and what new experiences I will have. Currently, I am deciding between the diving expedition in Sulawesi or the Himalayan white water rafting trip. I would like to go on these trips because they would both give me very good and new experiences, I’ve never been diving or rafting so both of these trips would teach me new skills.

I am very curious, yet excited about the year to come. I hope I learn new things that would help me in the future and I will meet new friends and other people that will be important in my future journey.
