um... so Oddessy all the eighth graders went up to cresent lake to a camp called camp David jr. we all stayed in cabins. for me oddessy was okay but i didnt like all the bus riding we did more of that then hiking there was some cool hikes though my favorite was probably the cape flattery hike were we got to see tatoosh is. some other fun things were hurricane ridge and the hot springs. the food was ok but the beds sucked and i got sick for some reason so that sucked. most of the counselors were cool i want to try and be one when i can. the best part about oddessy was free time: hacking and ping pong.
peace

in class weve been leaning about earthquakes. what i have learned it that there are 2 major types of waves, first the fastest: p waves or primary which move back and forth through the earth and these waves can travel through water. the second and slower wave: S waves or secondary wave which move up and down through the eart and cause more distruction then p waves, and for some reason these waves cannot travel through water. there also are Raleigh and love waves ( don't ask why they are named that) which also have there own movement characteristics.

In class we had these plastic trays called stream tables, so we went outside and got buckes full of dirt ten we poured water down the dirt some times we created canals and sometimes we didnt we whatched how the canals where changed and erosion and deposition happened.
for own lab we created a twisting canal in the sand and changed the incline of the stream table by putting books underneath we measured how much the canal eroded (it started out and 3cm) our data was all over the place we couldn't prove our hypothosis of find a conclusion because the were to many variables we couldn't control well enough and we really didn't know we had to control them like the shape of the canal and the place where we measured.

energy tansformations

well energy transforms when it is consumed by something else. it can be discribed like a food chain starting with the sun which sends out radiation which truns to convection and can be absorbed by a plant which will then have an increase in stored chemical energy. and then something will rat the plant like a squirell and the stored chemical energy will tansfer to the squirell. and the world will kepp on movin.
and i guess a cool energy tansfer is where an engine converts the potential chemical energy in gasoline and oxygen into heat, which is then transformed into a kinetic energy that moves a car.

Plate Tectonics

In class this week we started learning about plate tectonics. I missed the first three days and i was so lost at the begenning of this thing then it all came together and made sense here's what i learned:
There are three types of boundries in between different plates the 3 types are: convergent boundries which is usally where subduction happens if one of the plates is more dense the the one it is crashing into it will subduct and go underneath the other plate where it is pretty much recycled because is melted by magma, the subducting plates also cause deep earthquakes. the second type of boundry are divergent boundries where two plates move away from each other and magma fills that space with parts of new plate that is how new land is created. the third type of boundry is a transform boundey where two plates slide by each other.Tectonic plates are pieces of the lithosphere that are riding on the asthenosphere those are the two outer parts of the earth.
The specific plate my team studied was the north american plate. on the east side of the plate is a divegrnt boundry with the eurasian plate. on the south side it is up against the caribean and south american plate where many volcanoes and deep and shallow earth quakes happen but where it meets the s/am plate there is virtually no action
happening.on the west side whre it meets the pacific plate it is a transform boundry so many earthquakes happen. on the west side where it meets the eurasian plate it anothe spot where there is no evidence of a boundry so hey the eurasian and north american plate could be one who knew.
jeeeeeeeeeeeezz i cant belive i just wrote that much

Float your Boat

For our, float your boat lab we found out how the tempature of the water effected how many pennies an 8x8x2 tin foil boat can hold. we didn't know the exact tempature so we called them: Hot and Cold.
This is what we got:
-Hot:
Trial 1: 35 pennies
Trial 2: 32 pennies
Trial 3: 35 pennies
-Cold:
Trial 1: 39 pennies
Trial 2: 41 pennies
Trial 3: 41 pennies
So the colder the water is the more dense it is so the boats can hold more pennies.

Crowns and Density

OK in class we had this webquest where King Heiro II had five crowns made but only one was real gold. So we had to figure out which one that was. To find this we used density... the quest told us the mass and volume, so all we had to do was devide mass by volume to get the density, and we solved king Hiero's problem

-We watched a couple of vids bout density and we watched are fearless leader blowtorch some stuff i learned some stuff i guess mista G wants us to say what that stuff was so...
-I learned that that the hotter something gets the less dense it gets and the colder things gets the more dense
-Cept' once water freezes the density decreases again and that is why ice cubes float in ya drank
-To figure this out we colored some cold and hot water and put it in a plastic contraption and watched the hot water rise and the cold sink.
peace out

in class we did a lab about crayons floating in water.
in the beginning crayons can't float in the water because the are more dense then the h2o but we fixed that by adding salt to make the water more dense.
our team was figuring out how high the crayons floated in the water depending on how much salt was in there.
these were our results:
2 tbs: 3cms
4 tbs: 5cms
6 tbs: 6.5cms
8 tbs: 8cms

Weathering is the breakdown of stuff caused by air, water, plants, and animals. one example of weathering is water in rocks freezing and expand breaking the rock
Erosion is the movement or transportation of weathered material. One example of erosion is wind carrying away weathered rock
in the US, soil is being eroded at 17 times the rate at which is forms, and 90% of cropland is losing soil.
