Colorado Phet “Energy Skate Park”

Write about how the simulation works:

  • What happens when you press the play or reset button?
  • What does the energy graph show?
    What changes when you adjust the skater or track?
  • Which inputs (like the track shape or skater’s mass) change the outputs (like speed or energy)?

Use Everyday Examples
Help your classmates understand energy by comparing it to real life! Can you describe:

  • Kinetic energy like a ball rolling or you running?
  • Potential energy like being at the top of a slide?
  • Thermal energy like when brakes heat up or you rub your hands together?

Tinker Like a Programmer

Try changing one thing at a time (just like testing a program!). For example:

  • Change the skater’s mass. What happens?
  • Move the skater higher or lower. What changes?
  • Change the friction slider. Does that affect the total energy?

Track Patterns

Look closely at the energy graph:

  • When is potential energy the highest?
  • When is kinetic energy the lowest?
  • When does thermal energy grow?

when i press the play Butten the person on the skate board slide from the top to the bottom, and the graph will show the speed. When the person is on the top it has the most energy, and it go’s all the way to the other side of the ramp

potential energy is stored energy with a system position. It’s the energy an object that has the potential to be into other forms of energy, like kinetic energy. Common types include gravity, chemical, and nuclear potential energy.

Kinetic energy is the energy an object due to its movement. It’s a measure of how much work an object can do because of its speed and mass. The faster an object moves and the heavier it is, the more kinetic energy it has. Kinetic energy is the energy an object has due to its motion. It’s a measure of how much work an object can do because of its speed and mass. The faster an object moves and the heavier it is, the more kinetic energy it has.  Thermal energy, also heat energy, is the energy interact with the movement of atoms within a substance. This movement, which can include rotation, is what gives a substance its temperature. Thermal energy is a type of kinetic energy, the energy of motion. 

when i change the person become bigger but nothing else change. When i move the person lower it go to the other lower side. When i change the friction it go slower and slower.

how does the internet work

internet help you get online and search,chat,play,and work.

internet connect million of computer

router is a net working device

the internet connect to the router and switch anything you do on internet people can see it and, internet is a wire that can connect.


what’s inside the computer

Write a blog post abo

Write a blog post about three key ideas from the video. 
Possible ideas:

  • What are two systems inside a mouse used for sencer and light
  • What does the basic IO subsystem act as for the computer? It interrupt to CPU
  • What does CPU stand for? What is its main job?]central process unit.it is the brain of whole computer
  • How many instructions can a CPU perform in a second? Billions of instruction
  • What kinds of languages did human programmers use to write the programs running on the computer? java python c++ 
  • What two numbers does the CPU only understand?1 0
  • What is memory used for? To keep photo vidio

google docs vs MS word

Do you think the sites could be useful to you? Why or Why not? How are they different than the “look up” or “explore” or “define” function in MS Word or Google Docs? Which one is better? Or does each fulfill and different need? Create a blog post. I think google docs is better than MS word because it show the picture and i can search too in google docs. I think word is harder to use because its in microsoft and it is difficult to use

real life vs oregon trail game

THEY travel to have better life.

What were some hard things that people had to deal with on the Oregon Trail?  People have to make sure drink clean water.

What are three things that people needed to take with them on the Oregon Trail?shirt,bison,and food.

 Why was it a good idea to travel with others People traveled in groups called wagon trainson the Oregon Trail?ther is nadiv american.
