Galaxy Type

imageThe Messier 81 is a spiral galaxy. When I look at the galaxy there is a pinwheel shape to the galaxy. There is also a bulge in the middle where the red arms are surroundings. I am able to see red and blue colours around the galaxy.

The M32 galaxy is elliptical, a dwarf galaxy. This galaxy resembles a thick cigar. Compared to the Messier 81, the M32 has less shape and colour to it. The M32 is the largest and the oldest universe. Elliptical galaxy’s tend to be more 3D than other galaxies.

This galaxy named Coddington’s Nebula is a dwarf irregular galaxy. The Nebula does not have an exact shape or size however, they resemble some parts of the spiral and elliptical galaxy. This galaxy is small and includes dust and gas.

Oobleck Lab

1. Chemical A was white and powdery corn starch. Chemical B was a liquid that had yellow coloring.

2. It was a physical change since the powder and the liquid turned into solid/liquid goo.

3. I think it had both properties of liquid and solid. When it was on the table, it was hard and dry. However, when I picked it up to inspect it started to drift down much like a liquid. The oobleck did not bounce nor stay in a ball shape.

4. The oobleck was 2 states of matter at the same time. I learned about how an object can have both properties of solif and liquid

 

 

 

 

Science Circuit Challenge

I noticed in this experiment that the current stayed the same across the whole circuit. However the voltages were different. The voltage on light bulb 2 was larger since it was closer to the battery while light bulb 1 was smaller and farther away. When I added up the voltages on the light bulbs we had the amount the battery had which made sense to me. The farther you get away from the energy the lower voltage it has .
