In this lab we had to measure the height of the flag pole in front of the school using trigonometry.
We used a clinomater to measure the angle from our eye height to the top of the flag pole. We got 43°.
After we measured the distance from which we stood from the pole using a trundle wheel. We got 8.67 m.
We had to use tangent to and add the height from the ground to your eyes and add it to the height. We got that the flag pole is 9.72 m.
After completing the lab we compared our answer with other groups and the answers where varied by ± 1 m. We believe that this is because the instruments we used weren’t the most accurate and neither where some of the measurements.
- What do you know about infinity?
Infinity means never ending, something that is infinite goes on forever. There are infinite numbers, they just keep going on and on.
- How can you explain/makes sense of different sizes of infinity?
Even though an infinity has a never-ending number of numbers they have different sizes. The group of natural and whole numbers have an infinite amount of numbers, but the group of whole numbers is bigger since it has 0 and natural numbers don’t. Similarly, integers are double the size of whole numbers since it contains the opposite of each number, they are both infinities, but one is double the size.
- What are countable infinities? What are non-countable infinities?
A countable infinity can be counted, like the whole numbers. You can count 0, 1, 2, 3, 4…. If you wanted, you could keep going on forever. Counting all the decimals would not be countable, you would never reach one since there are infinite decimal places.
Divisible by very few
Are truly unique
We read two articles, and we had to right down a reflection on them
For the first article, it shows us how people will try and create a fake social media account to influence our thinking. They will try and scam you out of your money for personal gain. They do not care about how people feel and will use even very tragic things from themselves.
- What was your goal?
My goal was to take 5 minute showers
- Did you achieve it? How or how not?
To achieve it I took note of the time before getting in. After I shortened the amount of time I spent rinsing the soap off because before it took me way too long. I made sure that I spend as little time as possible in the shower.
3. What was the most challenging part of achieving your goal?
The most challenging part was making sure I clean myself properly. 5 minutes isn’t very long, so I had to make sure I can get everything done. After the first few times it got easier.
4. What would you do differently next time?
What I would do next time is have a clock inside the bathroom to make it easier to keep track of time to have an accurate reading of how much time I spend inside the shower.
5. Will you continue on with this type of goal? If you do, explain what you will do. If not, explain why you are satisfied with where you are at.
I will continue with the goal. It doesn’t seem too hard now and it will help with the environment.
