Humidity

Work on this in class on Monday and Tuesday.  If you need more time complete it for homework and hand it in on Wednesday.

Part 1: Relative humidity Reading: you do not need make a graph, just answer these questions
1. What is a hygrometer? How could you make one?
2. What is the change in the state of matter during evaporation?
3. Can a gas evaporate?
4. Use the hygrometer and the wet/dry table to find the humidity.What is the humidity in the room?

 Part 2: State of matter change of water graph:Use the graph in the back of the packet to answer the following questions.
1. What state of matter is water most likely to be in?
2. At 20 C, what states of matter can water be?
3. At 40 C would you more likely find water as a gas or a solid?
4. At a given temperature what can determine the state of matter of water?

Part 3: Relative Humidity Website  link about relative humidity.
1. Can the dew point ever be higher than the temperature?
2. How does changing the outdoor temperature impact the dew point?
3. How does changing the dew point change the relative humidity?
4. How does the indoor relative humidity compare to the outdoor relative humidity?

Water Cycle

Before we make clouds and discuss precipitation we are going to review the water cycle.

Complete the diagram of the water cycle.  State how water changes different states of matter during condensation, transpiration, and evaporation.  What are the four places water is stored on the Earth?  Where is water stored in the atmosphere? How is the water cycle powered? What are the 4 main types of precipitation?  How are they formed?

We will watch brainpop video together.
You will use the websites below to complete the diagram.

1. State three reasons the Earth heats unevenly.
2. What happens as air heats?
3. Describe how air acts in high pressure system.

Heating our Planet

This week we will be working with several labs that demonstrate how different parts of our planet heat at different rates.

Does the angle the sun hits the Earth affect how it is heated?

    SHINE A LIGHT ON EARTH LAB

Do land and water heat at different rates?

   HEATING LAND VS WATER LAB

Do dark colored surfaces heat differently than light colored surfaces?

   EARTH's AIR CONDITIONING LAB

We will incorporate graphing as a way to analyze our data.  What can the graphs show us?

1. Will there be a frost tonight?  How do you know?

Look at the graph below.  

2. What heats faster the land or water?

3. Which one keeps heat longer?

4. What month do you think the ocean is the warmest?

Land vs. Water

Does the Earth heat at the same rate?

We will use our mini suns to measure the temperature of different parts of the Earth.
