From Feet to Fathom Lab Report

I think it is important to have an international measuring system because every country has there own and having a measuring system everyone would know is very helpful because other people and or foreigners can work in other countries  besides there own. The materials we used were: Partner,Objects in the classroom (whiteboard, desk, hallway, SPACE book, Peep, Crayon box),Meter stick or measuring tape, Calculator.

List of ways to measure:

Pace: legs outstretched =1 yard approximately or 1 meter

Egyptian cubit= elbow to tip of the middle finger= 18 inches or 45 cm
Fathom = middle finger to middle finger across the body = 6 feet, 180 cm, 1.8m
Palm = across the palm of the hand = 3 inches or 8 cm
Hand including thumb = 4 inches or 10 cm
Span = from tip of thumb to tip of little finger= 3 palms or 9 inches or 24 cm
English yard = from fingertip of arm to nose = 36 inches or about 1 meter
Foot = 12 “or 30 cm approximately
Fingernail = tip of pinky =1/2 inch = 1 cm.

My partners and I have not seen any patterns besides the pattern of similar numbers for each measurement of the object. On the image above you can see all the numbers for each object. In conclusion the English method was very useful because you dont need to go out to find anything to measure with because you have it right on you. I also think that the way to measure with the nail was the best for me because I am used to centimeters and 1 nail is simply 1 centimeter. And I also think  that measuring with the nail was the was the easiest way to measure objects with because of the same reason it is accurate simply 1 cm. I think my partners and I did a great job with time because it only took us 2 periods to finish this lab I don't think we could of changed anything but to do even better on with time and finish the blog post quicker.

Forces and Motion

Yesterday we started anew unit called forces and motion. We watched quite a few videos on youtube as a class such as time warp and tawny hawks extreme skateboarding jumps. I am very excited about this unit and can't wait to learn more because I don't know much about this unit. But the few things I know about forces and motion are that we use force everyday in our lives even in our sleep, you use force to push a pencil, move a glass, or just simply walk or jump. I guess I know a little about forces but I don't really know how to explain motion all I know is that motion is when you move or walk and things like that but I am not sure if that is right. I want to learn well I don't know were to start. I guess I want to learn as much as I can in this unit. The way I am going to learn it is by researching, reading, taking notes in class more, and connecting. May my learning begin...HaHaHa...

Earths Inner Secrets

Who ownes the oceans minerals...

  Today and last Friday we had to get in to groups of four and debate about who owns the minerals from the oceans and who should get them. We had very strong opinions about who the ocean's minerals belong too for example Luka said the minerals should go to the people who can afford it and that life is business! On the other hand I said that they should get a grip and realize that the minerals are everyone and just because the other country doesn't have the money to buy the minerals it doesn't mean they have nothing to offer. Another choice is just to trade, the rich country does not always have all the minerals  that the less fortunate country ha and that is were the trading come in. We also had very strong opinions on what happens as a cause of underwater and surface mining. We said that underwater mining lets out pollution which kills a type of fish that is eaten by another that is eaten by another fish and so on and on and that destructs the food chain which leads to death and or end of man kind. And surface mining when they commit the process of deforestation for mining they should plant all the trees and plants back to be able to come back there again to more minerals. For example when a little boy plays with neatly organized toys he off course makes a mess to be able to play properly with it again he has to put everything back in to place. I think our group did really well and we were barely off track. I extremely liked this activity and would love to do it again. 

Crystal Garden Reflection...

 I think the crystals grew best on cotton balls and little mini pools. Unlike the cotton balls and mini pools the crystals grew worst on cardboard and wood. The borax was the easiest to grow crystals from. I think the ebsom salt crystals were the hardest to grow from and took the longest. The best method of growing crystals was spilling the liquid in the pool and there on it grew around and stuff. I have seen how stefans simple garden thanks to is pools of crystals became one of the best. I have learned that crystals take time to grow and need a lo of care to be successful. I have no new hypothesis. My error was probably that i did not make my sand pool a crystal pool. I would of done more things on cotton balls and made a bunch of pools. I have just a few more questions like, Do crystals die? How long does it take for crystals to grow to about 50 centimeters? Were do usually crystals grow?

Skills Lab....

 Not a while ago we did a lab... a skills lab! It was to help us with the unit that we are finishing off with. We were learning about the structure of the earth. This lab was supposed to help us with our studies about the mantel. To be exact the lab was called Modeling Mantle Convection Currents. We had to fill a bucket kind of thing with really cold water, then we had to fill in a small container with boiling hot water and put in food coloring and cover it with tin foil. We put the small container  inside and poked a hole in side the tinfoil. But before we made the tiny hole with a pencil we put tiny circle shaped pieces of paper from the hole puncher and sprinkeled them on to the surface of the water. So then when we poked the hole the fod coloring started spreading around and moving the pieces of paper and started to create continents and only 1 fell so it was like Atlantis. This lab was very educational and helpful, although not many people could complete the lab correctly from the 1st time

but everyone could do it the 2nd time. Next time we should try to read the directions more properly and most importantly follow them.

Crystal Garden...

Day 1
Today we finished off putting the crystal solution on to our gardens and we are gonna wait until tomorrow to see the process and how everything goes.
Day 2
The second day of since the crystals are growing. I checked on my garden and realized that the solution on my trees is already turning into crystals i touched the trees and they even feel like them let's see what happens tomorrow!
Day 3
My crystals are growing awesomely i am noticing a lot of improvement the manoamonium solution are turning in to needle looking crystals all over the ground took and. My bushes are going great they hardened and are starting to take a temporary shape. I think.
Day 5
My crystals made very little improvement but the ground is doing well, although it doesn't look like what imagined but it is good enough because some didn't even grow as well. And i think this what i have might be it.

Dynamic Eart...

?@~  In science class we were asked to go to a special website called "The Dynamic Earth" and here is a link http://www.mnh.si.edu/earth/main_frames.html. We were also asked to make a blog poste after we were done visiting the website.And i learned that the earth is actually made of 4 layers. The crust were we live on, the mantel, the outer core and the inner core. The core is HOT, hotter than the surface of the sun! The mantle is actually rocky and the core is iron. If you look at earth as an apple the crust is as thin as the skin of the apple. The inner core is under such pressure that it is solid metal unlike the outer core is fluid liquid that is extremely hot. 

   Diamonds grow at the level of 150km underground.By comparing different types of carbon atoms in diamonds, scientist can track the carbon's source. Most of the diamonds originate in the mantel. Now, you may wonder " How do diamonds get to the surface of the earth well, they actually hitch a ride in rare magmas called kimberlite and lamproite, which from by partial melting of the upper mantel. They drive their diamond passengers up so fast that in 4-15 hours they are up on the crust. You can find diamonds beneath cartons the oldest parts of continents. Why there? Well, it is way too hot for them to form inmost of mother earths upper mantel, but the upper mantel below the cartons is quite cold that is why diamonds are stable there.

This Week We Learned...

 This week we learned about the earth's crust and caves from the 2 Bill Nye videos we watched in class. The earth's crust is actually very thin comparing to the other layers Everything we see or even is too small to see is on the earth's crust. Scientists predict that the core is made of iron and is roughly 1500°c.Then comes the outer core and the mantel. The mantel is 1200°c. No one has ever drilled to the center of the earth so no results that are found are really accurate. 

 Then we learned about the caves they have a lot of  stalagmites which very slowly drip drop on to the ground and slowly become stalactites. Both are full of minerals.  Many different animals and insects live in caves there are 3 types: Tragloxenes- cave visitors, Troglyphines- Cave lovers, Troglodytes- cove dwellers. 

 I would really like to learn all of those things, because it would be interesting to learn how rocks get their look, how people find rocks, how they mine is it dangerous, What happens to caves after they are done mining, are there people living in side the earth, what to do when a volcano erupts, how far did humans go underground?

 

Lab Reflections...

We did 2 labs one was cooling race lab and the other one was called making water wetter. Each is very much related to water. The making water wetter lab took quite a long time because there were 5 steps. We all had partners it was a bit of a messy project, but it was fun and cool. The cooling races lab was fun we had a different partners and we had a lot of laughs. We had to put crushed ice into 1st cup and the ice cubes into the 2nd one. Then we put thermometers into each of the cups. After, we had to start timing how much was the temperature after 3,6,9,12,15 minutes. I think in the first lab (making water wetter) we should of dripped more accurately, we should of managed our time better. And I should of done a better job putting down data.
