Odyssey was ausome!  My favorite part was the hikes and going to Sol Duc hot springs.  The worst part was the rain the first few days but then luckily the sun came out the rest of the week.  The food was great and we were never hungry! The polar diving was freezing but fun. The talent show was fun the couselors skit was ausome they did the week at Odyssey of all the students.  All the students were surprized at how well I play the piano. Overall Odyssey was fun!

 As humans we have two main heat energy sources: the sun, and the earth. Unfortunately, the earth's heat can't support life on its own, so we are pretty much totally dependent on the Sun. (which will go out in a really long time). Pretty scary, huh?( I am glad that I wont be alive then)!

 The Sun produces heat and light and sends it to earth in the form of radiation. That thermal energy goes into plants, which use it, and light, and carbon dioxide to make carbon stores/sugar stores. They take CO2 and change it into carbon. Then the herbavor eats the plant and takes the carbon stores and adds them to itself. Then along come some people and eat the herbavor to get those carbon stores into ourselves.

This is energy transformations.

So  in Science we are doing some labs with stream tables, soil, and water.  My groups real world problem is erosion and how much soil is eroded with so much water.  The amounts of water are 1 water bottle 1 1/2  water bottles 2 water bottles 2 1/2 water bottles and 3 water bottles. My hypothesis stated that the more water the more soil that would get eroded.  My hypothesis was correct! My highest data point was over 610 grams and my lowest was 75.4 grams.  Some problems we had was the scale couldn't weigh the soil because the soil was too heavy also we were not able to get all the soilthat was eroded.  Questions I had if I were to do this again is: What would happen if we packed the soil down? Also What would happen if we got new soil each time instead of using the same soil?  What I learned was what meandering streams are ( curving streams).  I also saw how much soil was eroded with water. I think this lab is really cool and interesting.

In class we did a lab where we made boats out of tin foil and put pennies on them to see how many pennies the boat could hold.  My hypothesis was the mor salt the more pennies they would hold.  My group just had a 10in by 10in and folded them in fourths. We did 3 trials for every half film canisters of salt.  We found the average for each:

Average:                                         Amount of Salt:

12.33333333                                  0

13.33333333                                  0.5

13.66666667                                  1

13                                                      1.5

13.66666667                                  2

My hypothesis was incorect.  All the averages were around the same. If we did further testing I would have folded the sides up to keep out the water.

How does the temperature affect how dence and object is?

In science Mr. Gonzalaz had a hoop and a ball that barely fit inside. When he turned on the torch to heat up the ball, the ball's mass changed so the ball wouldn't fit through the hoop any more. If the mass of and object changes than so does the density. If the mass goes up (and not the volume) than so does the density. But if the volume goes up (and not the mass) than the density goes down. If they both go up equally than the density stays the same.

In science we are studying density (mass divided by volume).  We did a webquest where they gave us the mass and volume and we had to find out which crown was pure gold (that was the easy part). Then we had to find out what the other 4 crowns were made of and wright a persuasive letter to King Hiero telling him wich crown was pure gold and what the other crowns were made of (this was the hard part).

Heat is the vibration of molecules, the more they move, the warmer they are. If it vibrates too fast, a solid will become a liquid, and a liquid will vaporize.

There are four ways to make molecules vibrate: conduction, convection, and radiation.

Conduction is when a molecule bumps into another molecule and transfers some of that movement energy to the other. This can happen with solids, liquids, and gases. However, it's harder to transfer heat that way between liquids and gases, because the molecules are farther apart.

Next there is convection. It can only happen in gases and liquids because The warmer molecules will rise to the top since warm air/water rises, and will slowly lose it's heat. Then it will sink to the bottom, and be heated again.

Finally infra-red radiation, and it can travel through empty space. It is a type of ray that we cannot see, but it makes molecules vibrate when it hits them. Have you felt warm on a not so warm day when you stood in the sunshine? That is infra-red radiation.
