Volcano Questions How did the other group’s core locations compare to your selection? What other information would you need to make better choices? Did your core samples provide enough information to reconstruct the history of your volcano? Why did we only give you 3 core location sites?

Quick Write Why does the Moon have phases? (What causes the phase of the Moon?) What is rotation? What is revolution?

Size/Distance Scale of the Earth-Moon-Sun System

Diameter of Earth: 12,756 km Diameter of Moon: 3,476 km

Moon Phases Assessment Probe

Going Through a Phase Mrs. Timmons asked her class to share their ideas about what causes the different phases of the Moon. This is what some of her students said: Mona: The Moon lights up in different parts at different times of the month. Jared: The phases of the Moon change according to the season of the year. Sofia: Parts of the Moon reflect light depending on the position of the Earth in relation to the Sun and Moon. Drew: The Earth casts a shadow that causes a monthly pattern in how much of the Moon we can see from the Earth. Trey: Different planets cast a shadow on the Moon as they revolve around the Sun. Oofra: The shadow of the Sun blocks part of the Moon each night causing a pattern of different Moon phases. Natasha: The clouds cover the parts of the Moon that we can’t see. Raj: The Moon grows a little bit bigger each day until it is full and then gets smaller again. This cycle repeats every month. Which student do you agree with and why? Explain your reasoning.

Lunar Eclipse Assessment Probe People have been fascinated by lunar eclipses for ages. For a time, the full Moon seems to disappear as it changes color, darkens, and then reappears. Throughout time, people have had different ideas about what causes a lunar eclipse. Here are some of their ideas: A: A nearby planet passes between the Earth and the Moon. B: The Sun passes between the Earth and the Moon. C: The Moon passes between the Sun and the Earth. D: The Earth passes between the Sun and the Moon. E: The clouds block out the Moon. F: A nearby planet’s shadow falls on the Moon. G: The Moon’s shadow falls on the Earth. H: The Moon turns to the dark side and then back to the light side. Which idea do you think best explains what causes a lunar eclipse? Explain your thinking about lunar eclipses.

Solar Eclipse Assessment Probe People have always been fascinated by solar eclipses. During a solar eclipse, parts of the Earth experience darkness for a brief time during the day. Throughout time, people have had different ideas about what happens during a solar eclipse. Here are some of their ideas: A: A nearby planet passes between the Sun and the Earth. B: The Sun passes between the Earth and the Moon. C: The Earth passes between the Sun and the Moon. D: The clouds block out the Sun. E: The Earth’s shadow falls on the Sun. F: The Moon’s shadow falls on the Earth. G: The Sun shuts off light for a few minutes. H: The Sun moves behind the Earth for a few minutes and then comes back again. Which idea best explains what happens during a solar eclipse? Explain your thinking about solar eclipses.
