Give a brief description of an oil spill and how it can be cleaned up using science.

An oil spill is when oil is released into a body of water due to human activities. To clean up oil spills, scientists have invented many ways to clean up after this disastrous event. Even though there are many methods that are made in order to clean up the oil spills, some of them are very expensive and might even hurt marine life. These techniques that are made are usually referred to as “Separation Techniques” which is to separate the spilled oil from water.

 

Is science good for humanity? Do the benefits of scientific discovery outweigh the problems it causes?

Science itself benefits humanity because of how it gives us more understanding as well as knowledge of what we are trying to understand/the things we don’t know about, however, even though scientific discoveries produce good outcomes and also gives us more understanding, it will come with different causes and even negative impacts to the environment. However, even though it causes a lot of problems through discovery and also testing, it gives scientists and researchers more ideas as well as learn more about how to create new things that will make human life easier, and be able to create a new environment that will replace the one that both animals and humans lived in before. Scientific discovery outweighs the damages it causes if the experiment produces better outcomes than the damages and problems they have caused. Experimenting and researching allow humans to move on from where they began, if it was not for the scientific discoveries, our lives would not be as easy as it is now.

What makes a credible scientist?

For me, I think that a credible scientist is someone who is very confident in doing his line of work, and also a type of person that doesn’t give up just because of a small error that he can’t overcome, but try his best to solve that problem with all the resources he can do.

Why is the scientific ‘way of knowing’ used in medicine compared to other ways of knowing?

In the scientific way of knowing that is compared to other ways of knowing, such as religions, beliefs, cults, etc, it is more used in medicine because of how it is more reliable and proven to be more accurate than the different religions and also believes, for example, the scientific ways of knowing is more reliable and used because of the number of experiments they have done in order to achieve the accurate way, but in different “ways of knowing”, it is less reliable because it is not completely proven to be successful.

Reflecting on scientific investigations is important because you can get more accurate results by repeating investigations with improvements to your method. How would you improve your seed dispersal investigation if you were to repeat it?

If I was to repeat my seed dispersal investigation, I could have done better if I have only included more details within my investigation and also have included more scientific words, for example, within my investigation, I only had a couple of words, such as system malfunction. And also when I had done my experiment’s report, I had forgotten to include some details in when I have done the experiment, so next time, I would add more details in my investigation.

Key Concept: Relationships

 

  • Read the following text about the Key Concept: Relationships.
  • Consider this concept as you respond to the questions below.

 

Relationships in science are the connections and associations between properties, forces, objects, and ideas. Any change in a relationship brings consequences — some of which may occur on a small scale, while others may be far-reaching, affecting large systems like human societies and the planet as a whole.

 

Relationships in sciences indicate the connections found among variables through observation or experimentation. These relationships also can be tested through experimentation. Scientists often search for the connections between form and function.

What was the goal?

What?

Our Goal is to build a foldable chair that could turn easily into a table when you lean against it, and also make it easy to carry around by making it lighter.

Where?  

Our project was beach or any place that is a good place for vacation because it would be really convenient to eat and sit on a chair, so you wont need to bring a table and also a chair which will be more annoying to carry around.

How?  

We first started by preparing the things and the cardboard building it by first cutting out two long pieces of cardboard that is long and wide enough for anyone to lie down on, then we got another piece of cardboard and cut it out by 3 by 6 to make the legs of the chair, then we repeated that process 3 more times to make the other legs of the chair. After finishing the legs, we had made 2 other legs on the top corners of the chair, to make it able to support the top when the chair is transformed into a table. When we are done preparing, we started piecing them together, first, we taped the seat of the chair to the back of the chair, using tape, then we rolled the chair’s legs into a long-square-rectangle, then taped it together, and did that with the other 5 legs (the chair’s leg and also the 2 table supporters), then we had stuck the legs into the corners. After that, we had tried to get more tape and secure the chair’s taped places to make sure nothing fell apart.

Why?

We had made this piece of furniture to give better convenience so that people won’t need to carry a lot of tables and chairs when they are on vacation or another place. We wanted the table-chair to be able to carry things while still be able to turn into a chair when it’s needed.

 

How did you use science?

What did you learn?

In science class, I had learned how forces work, such as the forces of tension, compression, gravitational forces, air resistance force, etc. I also learned about how structures work and how they support the weight they are carrying, for example, for a triangle, when the weight is put on the peak or the top of the triangle, the sides of the triangle push up while the object or weight is pushing down, for a rectangle, the top of the rectangle take the weight of the object but when the weight of the object is too much, the rectangle’s top curves in and then collapses. I also had learned about how and which beams can carry the most weight and how they are reinforced, for example, if a beam is hollow in the inside, it is not as strong as beams with a corrugated strip of material because that if a beam is hollow, the weight could easily dent the beam and break through it, but if the beam is reinforced with a corrugated strip of material, its harder for the weight to break through because that the reinforcement makes the beam harder to be pushed inward, which makes the beam stronger.

What experiments or tests did you design?

An experiment or test I had designed is an experiment that I had done with the centre of gravity. I had first cut out 3 shapes, a triangle, a square, and also a circle. Then, I had tested the center of gravity by using a piece of string and then putting it on each corner of the shape, letting it dangle for a second, then drawing a line across the place where the string was, then after, I had repeatedly drawn it until each shape has lines intersecting in a single spot, the center of gravity.

How did you use the results?

I had used the results of my project with my chair-table to make sure which seat will be the most comfortable for the person to sit in, and also the most convenient and easiest to carry around.

Personal

How did you improve as a learner?

I think that I had improved as a learner because that I had learned more about science and how science works and also I had learned more about each of the subjects we had done, such as building structures, about the beams, the project with the chair, etc. I also had learned about the type of forces and how they work.
