Objectives: Today we will… So that we can… Set up our Biology Binders QQT about the Syllabus Prepare for Monday’s Eclipse! So that we can… Understand classroom expectations & routines. Describe the relative sizes and distances between the Moon, Earth and Sun. Model the process of a solar eclipse & contrast it to a lunar eclipse. Compare a total solar eclipse to a partial or annular eclipse & propose a scientific explanation for each. Use eclipse glasses to safely view the eclipse.

Bell Work: 1) Please take a “Unit 1 Overview” sheet. Please fill in the section called “Homework Accountability Log” like this: 2) Take out your biology binder (green if possible) and your signed syllabus. I will be around to give you stamps for them! 3)Tear off the signed Academic Honesty & Integrity Agreement. I will collect that.

While I am coming around… Review your answers to yesterday’s exit ticket with your table group. Try to agree on the correct answers.

Stand Up-Hand Up-Pair Up! A new routine. Explain: When I say go, everyone will stand up and put their hands in the air. Walk around with your hand in the air until you find another person who has their hand up WHO IS NOT IN YOUR TABLE GROUP. High five the first person you see who fits that criteria. That is your partner. Tell each other one activity that you plan to get involved in at PRA. As soon as you are finished talking, thank your partner, put your hand back up in the air and repeat until I say stop.

Quiz-Quiz-Trade! All of these questions are related to the syllabus – things like grading, classroom procedures, lab safety, etc. Remember, you have the answer on the back to check your thinking (or if you need a hint)!

Questions? Try to postpone deep questions about the grading system – these are easier to address once we take our first quiz and can start tracking our personal data.

Brainstorm: On Monday, all of PRA is going to go outside to view a rare event called a solar eclipse. What do you think you are going to see? What do you think is causing it? Use round robin or other strategy to give students opportunity to process/discuss/share.

Solar Eclipse:

Solar vs Lunar Eclipse:

Sun, Moon, & Earth Diagram not to scale. Earth orbits around Sun once per year. Moon orbits around Earth about once per month.

The Moon’s Orbit is Tilted:

Total Eclipse: The sun’s corona (plasma that extends out from the surface of the sun) is still visible.

Partial Eclipse:

Activity #1: Size of the Earth 2) Size of the Moon 3) Size of the Sun My 12in balloon is the E. Make the moon. Now, make the sun. 3in: 12in: 1200 in (100 ft – the room is 25 ft)

Activity #2: Ping pong ball is moon – hold at arms length – you are the earth Where does the bball sun need to be to eclipse?

Annular Eclipse

Summarize: If time, you can play quiz-quiz-trade or other review/summary activity with the cards. Two video options: Vox (may be better for older kids): https://www.youtube.com/watch?v=oNH3akWXaV8 Freeschool (may be better for younger): https://www.youtube.com/watch?v=is8OLhGgLAE As you watch, think of 1 question that someone who understood today’s lesson should be able to answer. Write the question on the front of your card. Write the answer on the back of your card.

Quiz-Quiz-Trade! All of these questions are related to the syllabus – things like grading, classroom procedures, lab safety, etc. Remember, you have the answer on the back to check your thinking (or if you need a hint)!

Wear the glasses we give you 100% of the time outside! Please emphasize eclipse safety with your students! Remind them to return permission slips in order to participate.

Homework: Signed syllabus if haven’t done so yet! Make sure your binder is in order and contains all items from our group “Table of Contents”
