In the lab we focused on the different types of electromagnetic energy. The purpose of the lab was to examine the different types of electromagnetic energy.
The results for infrared light you could feel the heat up close but not from far away. The beads also changed color in the light and in the classroom it lost its vibrant colors. I learned that infrared energy produces heat. Also I learned that UV energy can cause pale people to have sun burns.

1. The wavelengths are different; the red waves are longer, and the blue waves are shorter
2. Radio waves can be used to figure out distance. Light can show the red shift and blue shift.

We learned about blue and red shifts. We created waves in water to recognize what waves might look like. Smaller waves and larger wave lengths represented different shifts, and more results are on another tab. I am uncertain of many things. I learned that colors will change and they look like water wave lengths.

1. The red shift is where things are moving away so it is moving into the red spectrum.
2. It supports the big bang theory.
3. Radio waves can measure distance of objects.

2. What do astronomers use electromagnetic energy for?
3. What is the Big Bang Theory and what evidence do astronomers use to support the theory?

A light year measure distance in space. Astronomers use this because everything is so far apart in space and scientists use this so that the numbers are easier to work with.

Astronomers classify galaxies by their shape and formation (categories: spiral, elliptical, and irregular).

1. It is a cloud of gas and dust in space; they are huge in size and are the building blocks for galaxies. Nebulae are categorized into 5 different categories.
2. -Stars do not actually twinkle; it is just a misconception.
-Sun is a main sequence star.

2. What do astronomers use electromagnetic energy for?
- To find the distance between stars and planets (Radio Waves)
- What stars are made of (Light)
- If things are coming towards Earth (Red Shift)
3. What is the Big Bang Theory and what evidence do astronomers use to support the theory?
- The Big Bang theory is when all galaxies came from a mass and came together. The red shift supports this theory.
