Look for: Precipitation, low pressure center, and front…

18.B Apply scientific ideas and related evidence to evaluate whether the new mechanisms (air mass movement, interaction of fronts, and low pressure areas [causse]) that were used in an explanation of one large-scale storm are also needed to explain the patterns in the how the weather will change [effect] in the predictions made for three other storms occurring at a different time of year.

Recording noticings that align to each of the three rows of their chart:

air mass movement:

• Precipitation, low pressure center, and front lines all move together.
• Movement tends to be toward the east.

interaction of fronts:

• Symbols indicate a front that is a line associated with each storm.
• There are two such lines in storm 1.

low pressure areas producing clouds and precipitation:

• There is a circle with an “L” in it associated with each storm.
• Precipitation is falling around the “L”.
• Precipitation is falling in front of and behind the front lines.

Walk around to see what noticings students are recording before asking the whole class to report out. Here is a time you can recruit participation from students who don’t normally share. Quietly check in with students and ask them if they would be willing to share a specific noticing and to explain why they think it counts as evidence for the related science idea. Point to the specific noticing on their paper you want them to share and have the student put a star near it to remind them which one they will share the next day. Continue this as you resume this activity on day 2.

After this you will need to pause and collect Nov. 22 2019 Weather Forecast Maps to redistribute in the next class and on the next day.
