Mechanical and Chemical erosion

Mechanical Erosion meaning- Mechanical weathering is the process of breaking big rocks into little ones. This process usually happens near the surface of the planet. Temperature also affects the land. The cool nights and hot days always cause things to expand and contract. 





-Mechanical erosion







Chemical Erosion meaning: Chemical weathering is what happens when rocks are broken down and chemically altered. There are different types of chemical weathering, including hydrolysis, oxidation, carbonation, acid rain and acids.

Experiment :4 Aquatic Engineer

Question: is it possible to control the flow of water?
our question: what happens when you make a damn and then break it apart.

`Hypothesis: We think the water will create a whole in the sand (tornado)

Materials: bucket, ruler, sand, cup with small whole, tray, thingy that holds tray to make it stable

observation:

 at 20 seconds, the water is spreading through, then it starts making a small whole, at 50 seconds the water is starting to spread more. then at one minute, the water finally, starts making its way through the damn. Then a few seconds later, it quickly passes through the damn and makes its way there. Then finally in a blink of an eye, you can see the water reaching into the bucket.


procedure: 1. use unit math thingy's to build a damn
                    2. add water
                    3. break damn when all water is added
                     4. watch it flow

conclusion: wow! we are all very suprised! this experiment was something we never thought would happen, My group and I learned a lot.

wadi degla field trip

As we got out of the bus, 5K students were surprised by the amount of sand that was in the wadi, but then we realized that it wasn't just "sand" that formed weirdly. Dr. Bill taught us so many interesting facts about the wadi and how it turned out the way it is today. He told us all the different animals that used to live in this sandy, rocky area and how now it is way different than an ocean/sea it actually looked way different then what Mr. Bill explained. Then we fond out it wasn't SAND!

     We saw some very interesting fossils, and magnificent, unique rocks etc. It was a great experience to listen to a geologist's words about this Wadi because we were standing on the SAME, very grounds that he was talking about. It was just amazing to picture yourself millions and millions of years ago standing on ocean grounds, well (used to be ocean) It was just unbelievable to listen to all these interesting facts about rocks, animals, and basically everything concerning the WADI.

      I learned a lot on the hike, and Dr. bill taught us a lot as well. I think it was great to hike as well; to just not only listen to someone telling you stuff but you yourself seeing a visual of what a person told/explained to you.

      I really enjoyed the grade 5 trip to the Wadi, even though it was a little bit extra hot, and it got a bit tiring at times, but I liked the fact that we got to see and learn more about what we are learning in school. It was pretty fascinating and super cool. I personally loved the wadi, ALOT. \

   One thing that I thought that 5th graders are so lucky to have the advantage of doing, is the fact that we got to have a field trip to the Wadi itself. I think that's GREAT because we got to learn about Water and wind erosion/weathering etc. In not only the boring way, when teachers teach and talk to you about it, But we got the chance of actually going to the location of where erosion actually happened and we got to SEE for real! I think it probably got students more interested in erosion. I'm not entirely sure, but at the beginning of this unit I thought something way different is erosion, now I actually got way interested in it and wanted to know more! That's just my opinion.

SOME ROCKS  I FOUND

Virtual Reality

Wearing the VR glasses was very interesting and entertaining for me. I thought that it was super cool to look at a 3D phone that's on your head, and you would never even realize that it is just a phone! It was also Lots of fun to look around and not see the normal earth that we are living in today, but it is also very realistic. I really enjoyed wearing and experiencing the virtual reality life. The water falls and the floor etc, looked very alike as what it is today except when you turn around you can see continuous beautiful 3D objects and creatures. and you could kind of feel it too. I wonder what Virtual Reality was made for and why it was made and also WHEN?

experiment #3 flood

Question: what happens when the force of water is increased?

Hypothesis: Since the whole from this cup is bigger, I think the water will create more pathways in the sand. I also think that the water will go down quicker than the last experiment.

materials: bucket, ruler, sand, cup with small whole, tray, thingy that holds tray to make it stable

observation: 

first 10 seconds, the sand creates a huge path for the water to go through, then 50 seconds the sand creates a ramp-shaped stream 1 minute 20 sec forms the mini waterfall.more water managed to escape. This experiment was much different the experiment #2. The cup with the larger whole really made a big effect on this experiment. We noticed that the whole was the one thing that made the whole experiment 100% different than the last one we had done. Since the whole was bigger, the water came down quicker which led to the water coming into the sand quicker which changed the WHOLE thing. We were very surprised.

procedure:

1. put sand and clay on the tray
2. make sure it is 20 cm long on one side
3. put on edge of the table
4. put ruler and cup with a big hole on top of the tray
5. pour 4 cups of water
6. watch & learn

conclusion: This experiment was very fun. I learned a lot from it, (especially the big whole fiesta) We learnt that even the smallest things in objects, could make the biggest effect on a big thing.

APL quote

" Don't raise your voice, improve your argument." -Desmond Tutu

In my opinion, I think this Quote means that you should not just speak/talk, you're words should include a powerful message/meaning that is important. I think this because, In the quote it mentions, "don't raise your voice" and to ME, that little part of words means you should not just say something that is non-scense, or that has no meaning what so ever, you should say something that is strong and has a very important message, that people need to be informed about etc. I think this is a good quote because it makes people thinking, and it really influences me to change my actions. It would also most probably influence others too, to start thinking before they say something. For example, Whatever you/someone said could hurt someones feelings or make them feel bad. Or maybe it could make someone happy. Thats why you need to think before you speak. I am wondering if this quote also means something else that I am not noticing. yelling is agrivating others to do more.

experiment two: deposition

question: what happens to the land when it gets eroded?

Hypothesis: I think the sand will create a little area when the water combines into it.

materials: bucket, ruler, sand,cup with small whole, tray,thingy that holds tray to make it stable

procedere:Put sand and hard sand and clay in the bucket with pipes. Mix the sand and clay.

make sand 20 cm in the length is the side without the hole. Take the wooden wedge and put it under the sand side. Put the ruler under the bucket in the sand side. Pour water and wait for it t o happen!

Observation: 

the fisrt few seconds, water is creating a whole, (whirl) then at about one minute, a stream started then one minute and 15 seconds, sand started getting damp and soft. one minute 30 seconds a valley starts to form. at 2 minutes sand makes 2 paths for water. at 3 minutes 30 seconds all water has been poured. at 4 minutes sand starts to get hard and starts drying.

conclusion:  when we watched the water going through the sand, I noticed that the whole has a big effect and the size of the materials aswell.
