Good bye 5th Grade!!

My favorite things I enjoyed in science were the labs, the field trips, and the activities we did. I will miss 5th grade and the best science class but, I'm excited for 6th grade! Science is the best! You are the best teacher ever! I will miss you.

Windows on Earth IDL Project


I chose windows on earth because I love painting and drawing. I thought the project went really well. I had success in finishing my pictures. Some struggles that I faced were trying to find a picture and making the right paint colors. Some things I learned was information about the ISS and the pictures I drew. Something I would do differently in this project would be to try other materials instead of paint  and I would draw other pictures. The first picture I drew was at the South Atlantic Ocean taken on March 3, 2014. The second and final picture I drew was at the North Pacific Ocean taken on February 20, 2014. Here are the pictures I drew...

Windows On Earth

The ISS is orbiting 240 miles above earth. There a 39 astronauts on the ISS right now. The ISS is traveling 17,240 miles per hour. The ISS doesn't crash into earth or fly off into space because of the earth's gravitational pull.

5 bonus points

Matter is made of atoms. An atom is made of more particles. States of matter- solid, liquid, and gas. Each type of matter has its own melting point, and boiling point. Metal is a better conductor than wood. Heat leaves your hand faster so it feels colder. Wood is a better insulator that metal. You can barely see atoms through an electro microscope. If you burn paper that is a physical change because then it turns into ashes.

Sound

Sound travels in waves. Sound is a chain of vibrating molecules. Humans can hear 20 to 20,000 cycles per second. Oscilloscope measures sound waves. If there is low amplitude there's a quiet sound, if there's a high amplitude it's a loud sound. If there's a high frequency there's a higher pitch. If there is a low frequency there's a low pitch. Cold air makes sound seem like it's traveling slower. Underwater sound travels 1,524 meters per second. Through steel, sound travels 5,486 meters per second. Soft surfaces absorb sound.
