WEEK 1: 15-19 AUGUST, 2016
MONDAY 15/8
On monday, our warm up question was "Why do you think prokaryotes evolve into eukarytoes? What is the difference between prokaryotes and eukaryotes?" to which I answered that prokaryotes evolved because as living creatures, they needed to adapt to their surroundings. As time went on, the prokaryotes needed more organelles so that they could sustain their health and survive in the ever changing environment. The difference between prokaryotes and eukaryotes are that eukaryotes are more complex. They have more organelles, such as the nucleus and membrane bound organelles. Because they have more organelles, they tend to be bigger than prokaryotes.
​
After we completed the warm up question, we proceeded to a review about things that we learnt the past week, about the cell theory, prokaryotes, eukaryotes, as well as organelles that are found in the cell. Then, we were given time to work on our homework in which we were assigned to create an analogy of a cell, explaining how each organelle functions within the system.
TUESDAY 16/8
On tuesday, our warm up question was "What is the cell membrane? How do you think it keeps things from getting in and out?" To which I answered that the cell membrane is the outer-most layer of the cell that protects the cell by managing things that are allowed to enter and leave the cell. They do this by blocking things that belong outside of the cell, and making way for things to enter.
​
After we were done with the warm up questions, we listened to Ms. Disty's presentation about the cell membrane and how it works. We learned the things that make up a cell membrane, which are called phospholipids. We also learn how they let things in and out of the cell, through a process called diffusion and osmosis.
​
After that, Ms. Disty announced that we were going to do an experiment, so we spent the rest of the block planning the experiment, which included listing the materials, variables, our hypothesis, and the procedures.
FRIDAY 19/8
On Friday, Ms. Disty was absent, but we were assigned a workshop where we reviewed the types of diffusion and osmosis. We had the draw how the molecules transported themselves in every type of diffusion. After that, we continued our planning for the experiment.
WEEK 2: 22-26 AUGUST, 2016
MONDAY 22/8
On monday, our warm up question was "What do you think is Osmosis?", to which I answered osmosos is the process in which molecules diffuse from higher to lower concentration in order to achieve equilibrium. The second question was "What is hypertonic, hypotonic, and isotonic?". I explained how hypertonic is when there is more water inside than outside. Hypotonic is more water outside, and isotonic is an equal amount of water inside and outside.
TUESDAY 23/8
On tuesday, our biology class took place in the lab on the second floor, where we did our experiments. We started by preparing the materials for the experiment; which were 2 beakers, 2 pieces of potato, 2 teaspoons of salt, and 400 ml of water (200 in each beaker). We followed to procedures that we had planned the week before.
​
Whilst waiting for the potatos, we were asked to work on our formative assessment. According to Ms. Disty it is better to assess our understanding of the topic, based on how well we could formulate questions. So for our formative, we were asked to formulate our own questions that is worth either 1, 2, 3, or 4 points, depending on the difficulty. 1 points questions and what is questions. 2 point questions are questions that ask for a comparison. 3 points are earned by questions that offer a case study, and 4 points are earned by essay questions. We have to ultimately accumulate a total of 20 points. Later, our questions will be given to another class mate to be answered. Then, we are responsible for checking their answers.
FRIDAY 26/8
On friday, our warn up question was "How was the experiment? Did anything ahppen that you did not think would happen?" To which I answered that the experiment well because we were able to obtain the results that we wanted. There were somethings that happened that we did not expect, like both the potatos loosing weight, because we thought that the potato in the fresh water would actually gain weight.
​
After that, we started writing our scientific report about the experiment. She told us that we had to include a title that made actual sense and was related to the experiment, but she specifically mentioned that we could not title our report "Potato Experiment". Then we had to write an intro where we explained al the objectives of our experiment, our hypothesis, as well as our variables. Then we had to list down all the procedures that we took in the experiment, as well as all the data that we obtained from the experiment in form of a data table. Then, we had to interpret the data table, and then make a conclusion which has to include our analysis on the experiment.
WEEK 2: 29 AUGUST - 2 SEPTEMBER, 2016
MONDAY 29/8
On monday, we spent the entire period continuing our scientific report about our potato experiment, which we had to upload on our website by 10 pm that night.
TUESDAY 30/8
On Tuesday, we were talking about a new topic about cell reproduction. So our warm up question was "How do you cell reproduce?" to which I answered that they reproduced by cloning themselves, by dividing into two. Then we were given a mini lesson about the process in which cells clone themselves. IN this process, they go through many stages. The stages of the cell's life include the interphase, mitosis and cytokenisis.
​
After the mini lesson was done, we were asked to write down the definitions of all the vocabulary that were related to this topic.
FRIDAY 2/9
