In our last summative assessment, we looked at proposals of some mining factories, to mine asteroids. And then, we researched about mining asteroids – The Pros and Cons – and created a poster of it. We chose pictures, and wrote detailed paragraphs, explaining what we think is good, and what actually might happen if this does not work. With the last paragraph, we also wrote about how we thought of asteroid mining, and what could we do as well.
I thought I did quite well with this poster project, though I had a little bit of trouble with finding out the information. But I still think, that it was researched quite well, and had good amount of information. I wrote about the Pro’s and Con’s, and that took me a long time to think about because I was not sure with them. The pictures aren’t that bad, and they do show what asteroid mining is, though I missed out on the sources which I should have done. I also hate how the pictures and text looks extremely awkward since there is more text than writing. Overall, I enjoyed this poster making project and hope to make a poster again.
For this unit in 7th grade science, we’ve been studying lots of chemicals. We are also learning about chemical reactions, and also to tell the difference of a chemical change and physical change. Our summative assessment task was too create a poster about a chemical each one of us chose, and we were to write about how it affects the society. I did my poster on a chemical that is very important in human life, called chlorine.
Compared to my classmates, I have not written down as much. However, I think I chose good topics, and was also able to explain them. I may have forgotten to write about some things, and I also do not think the layout looks very good either. I have bigger pictures than words, since on my last poster, all I had were words. So this time, I decided to have a fair amount of both words and pictures. I am also glad I did not forget to add the links to pictures and sources, and I had also used Easybib for my bibliography. Overall, I think did a pretty well, and I am quite pleased with it besides the layout.
If I had another chance to do this poster, I would want to use my time more wisely and have the poster ready before the class it’s due. I also think this poster shows that my organization was not very good for this project, since if I were organized, I would not have to hand out my poster crumpled or bended on the sides. And the layout looks quite terrible, which shows I was hurrying to finish this and my sources look out of place. I would have want to think more of the layout, and also my organization skills.
This is a voicethread about a pigs heart that we looked at last week, and this voicethread explain what each part is, and you can see how the heart looks like since there are pictures we took. I couldn’t record my voice with this voicethread, so instead I typed up my words.
For our first unit in Science, we looked at the nutrients in food. We all chose one food that we wanted to see the nutrients in, and I chose hot chocolate. I chose hot chocolate, since I love chocolate, and I also enjoy drinking it. First we had a practice test with some food that was already prepared, and we did tests to see the nutrients in those food. Then, we did the tests with the food we chose, and made a presentation of it.
I don’t think I did a really great job for this project, because I did get confused at some parts, and I also didn’t have enough research done. At some parts, I had to do everything at the last minute, which made some of my last pages horrible, and didn’t have enough information. I think that I could have done a better job with some parts, such as the parts where we explained how we did the tests. I think I earn about 3 or 4 for my project, and I hope to do a better job next time.
During science, we created animals for our unit.
Each one of us created three animals each, and we voted for the most “realistic animal” and the most “unrealistic animal”. I got five votes in total, but I didn’t have enough votes to win ;(
This picture is the one that is supposed to be “most realistic”. I think I got 3 votes for this:)
This is the one that is supposed to be “most cutest”, and I got about 2 points for this.
And this is the most creative and unrealistic one
This unit for Grade six science, we are doing one unit of forces. And the experiment which we finished earlier this class, was too put a egg in box, with anything inside it too stop the egg from cracking when we threw it down from the roof.
First of all, are class broke into 4 teams, and each team got one egg each. My team, which included Sophia, Juulia, and Charlotte. When we got our egg, our team started off by planning what we will put inside the egg to stop the egg from cracking. We decided on bringing elastic to hold the egg, cotton, and lots of marshmallows. We decided to bring marshmallows half to keep the egg from cracking, but the other half since Sophia and me wanted to eat the marshmallows.
The next day, we all brought in the tools we needed, and we started cushioning the egg. We had a small cardboard egg, and the first layer we used the cotton to make it fluffy. Than on top of that we had a big layer of marshmallows. On top of that, we placed the egg which was inside a small plastic with cotton in it. Then more marshmallows over the plastic box, and then a layer of bubble wrap. After that we finally closed the box and put about fifty layers of tape. And on op of that, we had a thick layer of cotton and on top of that, we had bubble wrap. Over the bubble wrap, we put marshmallows for more cushion.
When we threw it down from the roof, I was scared since I didn’t know what happened to the egg, but when we unwrapped it(which took about 15min), I was relieved because it didn’t break.
Then we did out second project in a smaller box, we did the same thing but without some of the cotton layers. I didn’t really mind if the egg broke, and to my surprise, the egg did actually break. And I thought yolk would come out, but it didn’t since it was hard boiled unlike the other team.
I really enjoyed this project, and I had a lot of fun creating the cushion and I hope there will be another project like this later on
“Kate and Sophia are out rowing in a boat on a small lake. To their surprise, on their boat they find a big stone. Since they don’t want to pull the stone with them, they throw it into the lake, and it sinks to the bottom.
When they throw the rock into the lake, will the water level rise or fall?
Many people answered by saying it would stay the same because the rock is so small. This is true, but it will either rise or fall a tiny tiny bit (even if we might need a computer to detect it). If it helps, you might want to imagine that they are models in a container of water instead of on a lake.”
This is my homework for science class, and it is due today. However, I forgot about it, so I am doing my homework during science class.
The water level will rise. It wouldn’t fall, because if a stone falls in, even if it’s a little bit, the water level will rise. But nobody would realize the water level rising, because it would be so little.
During class today, we mixed 50ml of water and alcohol. After we mixed the two liquids, the flask contained with the two liquids, bubbled up, and the flask became very hot. I thought it would go up 100ml, but it only went up to about 95ml.
I think it bubbles up because water and alcohol can compound easily. Alcohol can evaporate, and when water is together, it evaporates faster. For example, when you get a shot, before you get a shot they wipe the spot where you get your shot with alcohol because alcohol dries fast, and the germs can’t live in dry places. So they use alcohol to kill germs. So when the two liquids compound together, the liquid gets hotter because of the energy in the particles. Then it evaporates, and it turns it in to bubbles.
