What subject did you choose?

Why causes rock to slide down a slope?

Why did you choose this subject?

I have a interest in geology. another reason why my partner Steven and I  wanted to do this subject is it would be very interesting to find out what type of level the slope has to go through causing rocks to slide down a slope.

What are you hoping to learn?

i am hoping to learn what will cause rocks to slide down a slope.

This is my second blog entry 2018-12-20

Step 1

Define a Real World problem to solve and connect with a mentor. 

 Me and my partner Steven chose the topic of “What causes rock to slide down a slope?”. Steven is veryinterested in geology. both of us wondered  what solutions we can make in order to help solve the environment. As for this case rock-slides and avalanches can occur with rocks and could result in destruction of houses and possibly entire towns and villages. I wanted to find out the causes of these disasters and possibly find a solution, since Port Coquitlam is nearby Burke Mountain. This topic is original, as it is a project that I have interest in, and that it doesn’t violate against any of the “Topics to Avoid” list. Also, this topic has a real world problem behind it and it is an important topic to know for the near future.

As for finding a contact with a mentor, Steven and I have found a reliable website, prestoexperts.com, that offers expert mentors on many different fields. For this case, I have chosen Geology as the main source of field. Although I didn’t made any contact with a tutor (they required money in order to be hired), I have prepared a conversation to talk about with the mentor.

we will state with the mentor my purpose on finding more about on this topic, the real world problem that applies to this topic and my purpose on this topic (all mentioned above). I also have prepared various questions to ask the mentor in order to gain more information on my subject (example, “How often and destructive can it get”; “How many casualties occur each year from this”; “What is the chance of survival if one were ever to occur”, etc.). I would do this by email.

Step 2:

Hypothesis and websites we will be using;

If we change the amount of rainfall then the amount of rocks falling will increase. Or Independent variable will be the rainfall the dependent variable will be the amount of rainfall we are pouring down on to the slope and the controlled variable is the pebbles that we will be using. 

the website we are going to using is https://www.scientificamerican.com/article/sliding-science-how-are-landslides-caused/ this website is going to be one of our main websites of use because it has very valuable information on our topic it shows us alot on what causes landslides and what type of erosion, natural disaster, and the type of bad weather that would need to happen for a very big slide to occur what this website can also help us with is how to develop a final product for the experiment because the website is also formatted like an experiment.

Secondly a website we are going to use alot is https://earthsky.org/human-world/what-causes-landslides this website allows us to  see landslides from pictures instead of websites having a bunch of information and no pictures what we would be getting with this website is Examples of landslides in real life. We will also be getting different information then we would get from the first website allowing us to get a bunch of research from different websites so we can have the most information we can

The third website we will be using is https://opentextbc.ca/geology/chapter/15-1-factors-that-control-slope-stability/ it allows us to know  control slope stability and prevent rocks to slide down a slope which could help us write and extra paragraph about how we could prevent this issue because it would be better and more formal if we include a prevention with this problem

Step 3:

The Procedure for our Project; 

 

  • Get Cardboard, Clay, pebbles, pencils, (colored) and paint. Then set up the experiment (refer to image 1)​
  • Get a 20 Ml, 40 Ml and 60Ml cup of water​
  • Get another piece of carboard big enough to cover the top of your prototype and poke in approximately 10 holes with a pencil above the slope you have created with clay.​
  • When you have finished step 3 pour the 20 Ml of water and then make observations as well as collect all measurements of the amount pebbles that have slid down the slope.​
  • Repeat step 4 but with the 40 Ml of water and the 60 Ml of water.

Third blog entry: January 12 19

This is going to be for step 7, where we talk about the layout of our entire project. For storing our information we are going to display it on a PowerPoint and describe all of the steps in the scientific method that we are going to do. For our testing, we are making a model of the prototype we had designed out for the project.

For step 8, we had used multiple websites, but there were 3 in particular that we especially used.

Buddies, Science. “Sliding Science: How Are Landslides Caused?” Scientific American, 6 Feb. 2014, www.scientificamerican.com/article/sliding-science-how-are-landslides-caused/. This is the first website.

“What Causes Landslides?” EarthSky, earthsky.org/human-world/what-causes-landslides. Second website.

Earle, Steven. “Powerbanks Geology.” Introduction to Sociology – 1st Canadian Edition, BCcampus, opentextbc.ca/geology/chapter/15-1-factors-that-control-slope-stability/. Third website

Fourth Blog Entry January 14, 2019 (Steps 4-6)

For step 4, we had conducted the experiment. We had received the results. The results are: (out of 200 rocks)

250mL – 23 rocks; 500mL – 35 rocks; 750mL – 54 rocks; 1000mL – 67 rocks

We had displayed this data on a chart in our PowerPoint and on a graph which looks like this.

This is what our model looks like.

For steps 5 and 6, Steven and i have prepared a conclusion. I am going to list this in a QnA format.

Q: Did the experiment support the hypothesis?

A: Although the numbers don’t seem that shocking, the experiment had indeed supported our hypothesis. Our original hypothesis was: if the amount of rain increases, then the amount of rocks that will slide down the slope will increase. And based on the data that we have retrieved, this fact states true.

Q: What kind of real-life applications does this apply to?

A: Since landslides are a huge problem to our society, especially to us, since we live near a mountain, it will best apply to geologist and construction workers. Having that knowledge may give them solutions to prevent any future landslides, or build buildings that may be resistant against them.

Q: If you have to summarize this entire procedure into a couple sentences, what will it be?

A: The most rocks that have fallen is 67 rocks, after it has been poured by the 1000mL cup. The least is 23, by the 250mL cup. The average rock amount that has fallen between the four of them is approximately 45 rocks.

Q: What possible errors may have occurred in your experiments?

A: In our model, we had the intention to make our slope on a 45 degree angle. However, the clay dried off too quickly, and instead of a 45 degree, it’s 34. We had made about 10 holes for the water to fall through, but some of the holes are misplaced, making about 10 rocks unreachable for the water to reach.
