My Reflection

Overall during these last 6 blogs, I've been partially correct. The only thing is sometimes, I'd leave out some information on how to solve the problem. Through out this unit, I've learned a lot. I've learned about all of the different types of energy, and the one essential law to energy. To me, I think my blogs could have been better. I think if I researched and understood the topic a little more, I could have gotten every aspect of my blogs correct. For example, when I did a blog on Week 5, I was incorrect because it was an energy conversion, not Kinetic energy.( The when you put the cup on the table topic.)When I read my comments, overall I was told I was good but that I could've done better. And I always strive to do better. What I can do in my next cycle of blogs is to research and comprehend a little more. Then, I'll understand the science behind our topics. I'll also be able to write better blogs and receive better comments. This concludes my reflection on my blog status.

Week5_Prompt#2

The reason why the cup got more kinetic energy is because when you out the cup on the table it received more kinetic energy. The formula for kinetic energy consists of speed and mass. (You multiply speed times mass.) So when you put the cup on the table, it's speed times its mass gave it a higher kinetic energy amount. The table lost kinetic energy because when the cup came down, some energy was transfered to the cup. So in conclusion, the cup got more kinetic energy and the table lost some.

Week4_Winner Takes All

The problem the Design Squad had to solve was to make a a sled, but it had to be able to ride through grass instead of snow. It had to be man maneuvered. They had to find the right materials for the sled to go down the hill. At first, the red team tried out all of the different sleds to see which would be able to slide down the hill. None of those prototypes worked. Then ,they decide to try and make a sled with wheels. The blue team are going to try that idea too. Then someone came up with the idea of doing the sled in sections. She said it would have 3 sections and be able to twist and turn. You'd also be able to hook on sections. During this challenge the Design Squad listened to each other's ideas and made great suggestions. They brainstormed, and corrected each other, and were a great team.

I would approach this problem by riding the different sleds down the hill. Then, I'd brainstorm until I came with a good idea. Then, I'd build a prototype and ride it. If it didn't work, I'd go back to my ideas and find out what went wrong. If all went well, I'd build the real deal and test it to make sure it works. That's how I'd approach the problem. What I learned from this episode was to work together with your teammates. Listen to their ideas and they will listen to yours. I also learned that everyone has good ideas so you should listen.

Week3_Prompt2

The reason the air around the surface of the water got cooler is because of evaporation. Since the water evaporated, the energy (and heat) decreased. Since the heat from the water decreased, so did it's surroundings. Basically, this is endothermic. (Because it gave off energy to it's surroundings.) So in conclusion, the air got cooler because of it's endothermic enegry.

Week2_Prompt#1

The energy from the ball dropping didn't disappear. My reason is because of the law of conservation of energy. According to the law, energy cannot be created or destroyed. So my friend was incorrect. Energy may not be able to be created or destroyed but it can be transferred. So when the ball reached the surface of the floor, it transferred some it's energy. This caused some of it's amount of energy to be reduced, making it stop bouncing. So in conclusion, the energy didn't disappear it was transferred.

Week1_Prompt#1

The nail head gets warm because of the kinetic and thermal energy associated with the hammer coming down upon it. The formula for kinetic energy is mv2 divided by 2. So when you bring the hammer down upon the nail, you have your kinetic energy. When the hammer hits the nail, the molecules in the nail move faster. When the molecules in the nail move faster the temperature increases. Thus causing the thermal energy creating the temperature to increase. So in conclusion, that is the process of the hammer and the nail.

Technology in Science

I like science because if I become the doctor when I grow up, at least I've learned a few things. ( A doctor is one of the many of my possibilities.) I like using the computers during science because it helps me get a better feel with the computers and how they work. So far, we've learned about the different types of energy and the formulas. We've also learned a little more on the computers.
