"Relative Humidity"

Earth Space Science
Periods: 1, 2, 3, 4/5, 6/7, 10
Time: 50 min

Indiana State Standards: 1.11
Composition of the atmosphere...

Daily Goals: SWBAT -
* understand that relative humidity is the ability of air to hold water vapor
* know that air is able to hold more water vapor at higher temperatures
* interpret graphs to show water vapor at both high and low temperatures

Schedule

1. Entry Work Question: 2-3 min
2. Hook: 5 min
3. Together Work: 10 min
4. Go Over Homework: 35 min

Lesson Plan

Entry Work Question: Define "Relative Humidity."

Hook: Shower Activity
- have you ever gotten out of a shower and seen the mirror all fogged over? what causes that?
- isn't that called "humidity"
- how much humidity (or water vapor/gaseous water) can the air hold at one time?
- we're going to be looking at that with the graphing activity on pg 283!

Together Work:
- everybody turn to pg 283, and we're going to read the instructions together!
- we're going to work through Analysis Problems 1 together.
- now try answering Analysis Problem 2 on your own!
- write down both of these answers (be sure to put your NAME, DATE, and LABEL on them) and turn them into the Period Box

Go Over Homework:
- students take turns volunteering reading the questions and answering (raise your hands if you are willing to read the question or answer) and then we go over the answers
- today we are going over the Student Guided Reading Questions for Chp. 11, Sect. 1. (1 - 20)

*Differentiation -
- students that have trouble reading will have the questions read for them
- students that have trouble with the concepts will have them acted out for them

*Assessment -
- students will be assessed on two questions over their ability to interpret graphs from pg 382, Student Problem Solving Lab.

Notes for next time:

Do Not have football players represent the concept of conduction by acting out molecules transferring energy! They will tackle each other in class and it will end up recorded on someone's phone. Learn from this mistake. Ugh.
