Unit 3, Lesson 1: Stars Intro
Learning Target: I can explain why stars lighting up is a threshold.
Class Activities:
1. Students came in and picked up three handouts-- the unit 3 cover page, the new vocabulary sheet, and the stars intro handout.
2. Students worked on the "K" and the "W" of the KWL chart. Basically, I want to know what they already know about stars, and what they're curious about.
3. We moved on the Part 1: Recap of the Big Bang. Here's the passage, with the blanks filled in:
The Big Bang theorizes that 13.8 billion years ago, all the energy/matter in the universe was condensed into a point smaller than you can imagine. The ingredients that caused this to happen are unknown. The Goldilocks Conditions that caused this to happen are unknown. No one knows what caused this point to expand, but suddenly, it did. In a moment, space, time, and forces that govern our universe, like gravity, were created.
There’s a lot we don’t know about the Big Bang Theory, like what came before it (answers may vary) . However, there is enough evidence, like redshift to prove that some major expansion of evidence occurred about 13.8 billion years ago. The Big Bang is considered an important threshold because it created the building blocks of everything that exists in our universe.
4. We watched a video clip that explains the formation of stars. It's cool, but it does move through the info pretty quickly. I watched it twice to really get it. The answers to the video clip questions (Part 2 on the back page) are:
1. cooled
2. hydrogen and helium
3. gravity
4. it heats up and pressure builds
5. there are now many sources of energy (all the stars act like billions of little batteries)
5. We reviewed protons, neutrons, and electrons by filling in the blanks of Part 3. The blanks are filled in the passage below:
Everything in the universe, biotic or abiotic, is made of things called atoms.
Atoms are made of protons, electrons, and neutrons, which are in turn made of even smaller units called quarks.
Protons have a positive charge and typically repel each other. Electrons have a negative charge and also repel each other. But a proton and an electron attract one another and become stable. Hydrogen, one of the simplest elements in the universe, has one proton and one electron.
Sometimes, when temperatures are hot enough, protons can attach to one another. However, protons attaching to one another releases a little bit of energy, called photons. These photons emit light, which we here on Earth see as stars.
6. We filled in the "L" part of the KWL chart.
