Good bye 5th grade

I had a lot of fun leaning and all the hands on projects in Science. I liked the field trips and the labs. I liked how we didn't use much of the book. I also liked how much homework we had because I thought it was just the right amount of homework. Another thing I liked was the partner work projects and the end of the year jobs we had. That was what I liked about the fun learning activities and the hand on projects in Science.

Balloon Investigation

I think that the balloon with the most chemicals in it will blow up more. The balloon with less chemicals blew up more than the one with the most chemicals did.

IDL

I chose the Science Photo Journal because you could take pictures and describe the science in the photos. I feel it went really good because we described all the science and used the vocabulary words. We had 10 photos and sentences about the photo and we even had sound videos. We had a little struggle of what to take picture of but we looked at the surroundings and the vocabulary words. I learned many science words and science around me. I would do the photos and sounds differently next time. I liked my job but knowing some of those other jobs like windows on Earth could of been really interesting to do. This is a picture of a spectrum. I had fun doing my IDL this year. It was really interesting.

Sound

Did you know sound travels in something called a longitudinal wave? Ocean waves vibrate up and down at a right angle o the direction of the wave, that is called a transverse wave. A sound wave is a chain of vibration of molecules. Also the vibration pushes nearby air molecules back and forth, making the local air pressure rise and fall. As the cymbal pushes into the air, air molecules are packed tighter, creating a compression. When the cymbal pulls back in its vibration, it creates a low pressure area called a  rarefaction. A oscilloscope is designed to measure sound waves. Did you know how loud a sound is depends on the force of the compression, or the amplitude?

Ants In Space

The ISS does not have gravity and the Earth does. My question was do the ants make antenna-to-antenna contact? My other question was how often do they make contact and do any ants avoid contact? I investigated the social interaction of the ants. The ants communicated by having antenna-to-antenna contact. Two of the ants avoided contact and only four ants did make contact. I really liked doing the Ants In Space investigation.
