TES Unit Review

TES Unit Review

By Rebeca Portillo

Today we will be reviewing for your Unit Test on The Earth System

This slide deck will have review information, fill in the blank questions, poll questions, multiple choice, and short answer responses. Ensure you participate by answering questions to the best of your ability and participating in class discussions to ensure you are ready for tomorrow.

TES CHAPTER 1: ​Why is East Ferris running out of water while West Ferris is not?

​ When we began this unit we started with the question stated above.

Think back to some reasons why East Ferris is running out of water while West Ferris is not?​

Science | 5th

TES​

Open Ended

When we started chapter one, we discussed water availability on Earth. Observe the image to the left, how does this image explain the availability of water on Earth?

Answer: Most of Earth’s water is salt water, so there is not a lot of freshwater on Earth.​

​

Let's think back, Where does most of our freshwater come from?​

Some text here about the topic of discussion

Multiple Choice

Which of the following arguments best supports the choice to get water from glaciers?

• There is much more water in glaciers than in oceans

• Glacier water is fresh and ocean water is salty

• Glacier water doesn’t evaporate and ocean water does.

• Glacier water molecules are larger than ocean water molecules

Multiple Choice

Which of the following arguments best supports the choice to get water from oceans?

• There is much more water in oceans than in glaciers

• Glacier water is salty and ocean water is fresh

• Ocean water doesn’t evaporate and glacier water does.

• Ocean water molecules are larger than glacier water molecules

Chapter 1 Key Ideas​

TES Chapter 1​

The amount of available freshwater decreases when people use more than the amount that flows into their area.​

Almost all of Earth’s water is salt water in the ocean. The limited amount of freshwater is mostly limited in glaciers and groundwater.

Chapter 2: Why does more rain form over West Ferris than East Ferris?

Draw

Label the water cycle. Use the letter E for Evaporation, C for Condensation, and P for Precipitation

Multiple Choice

During evaporation.....

• water vapor forms from liquid water that has been heated

• the molecules are really close together, tightly packed

• liquid water is frozen

Multiple Select

During condensation...

• water vapor forms from heated bodies of water

• water vapor gets colder and turns back into liquid water

• the molecules are really far apart

• the water vapor molecules move closer to one another forming liquid

Replace

Liquid bodies of water become water vapor. This happens because the water heats. Notice how the molecules go from close together to separate, this is because the water has been heated.

​Evaporation

Evaporation water molecule structure:

Condensation happens as water vapor rises, it cools. This leads to the water vapor molecules to start​ coming together, forming liquid. (See step 2). The liquid the falls down as rain or precipitation.

Condensation and Precipitation water molecule structure:

Open Ended

Observe image A. The arrows represent the movement of water after it has been heated on a hot summer day. Explain why the molecular structure of water is incorrectly shown in section A.

Multiple Choice

On a summer day, water particles from the ocean change phase as they move into the air. Which model best shows this change?

• A

• B

• C

• D

Chapter 2: Why does more rain form over West Ferris than East Ferris?​

Answer: A lot of rain forms over West Ferris because water evaporates, condenses, and precipitates. When water in the ocean gets warm, it forms water vapor. As the water vapor rises, it cools down and condenses to form liquid water in the atmosphere over West Ferris. During condensation, the water molecules get cold and move closer together to form liquid water. The liquid water falls back toward Earth as precipitation (rain). This is why West Ferris gets a lot of ra​in.

Chapter 3: Why is more water vapor getting cold over West Ferris than East Ferris?

​Observe this table: What information does it provide? Which season does it rain the most? Which season does it rain the least? In which season would we have the least amount of groundwater?Why? What is needed for rain to fall? Discuss as a class. ( 2-3 minutes)

​The least amount of groundwater would be observed during the winter time in Worcester. The table shows that the amount of precipitation during winter is only 10.5 inches, which is the least of all 4 seasons.

​​Explanation:

​

​Groundwater forms when rain (liquid water) falls and soaks into the ground. Therefore, when there is less rain, there would be less groundwater in Worcester.

CHAPTER 3: Why is more water vapor getting cold over West Ferris than East Ferris?​

West Ferris must have cooler temperatures, whereas East Ferris might have warmer temperatures. The warmer temperatures does not allow the water vapor to cool and condense.​

Chapter 4:

Why is there more water vapor high up over West Ferris than East Ferris?

Multiple Choice

Observe the image. In which direction does the water vapor move when there is a mountain? Select the most accurate response.

• Its just moving to the right.

• Its moving to the right and upward.

• Its moving upward only

• It's moving to the right and upward into the atmosphere.

Poll

Why does West Ferris have more water vapor than East Ferris?

• West Ferris is experiencing a rain shadow effect, that's why there's so many plants!

• East Ferris is experiencing a rain shadow effect because the mountain is acting as a barrier, not allowing water vapor to condense.

• East Ferris has less water vapor because it is too cold there for water to condense.

• West Ferris is experiencing a rain shadow effect because it is so hot, that side is basically a desert.

Chapter 5: How can East Ferris turn wastewater into freshwater?

Multiple Choice

True or False: In a chemical reaction, matter is created and destroyed.

• True

• False

Multiple Choice

True or False: During a chemical reaction a new molecule is formed.

• True

• False

Multiple Choice

True or False: During a chemical reaction new atoms are formed.

• True

• False

Draw

The blue atoms represent Hydrogen, the yellow represents chlorine, the green represents sodium, and the red represents oxygen. Show the new molecules that formed. Is this a chemical reaction?

Multiple Choice

True or False: During a chemical reaction atoms are rearranged to form new molecules.

• True

• False

Open Ended

Explain how this image shows a chemical reaction has occurred. In your response, include the words: atoms, molecules, rearrange, and matter, created, and destroyed.

Chemical Reactions Recap

A chemical reaction occurs when....

​-The atoms of molecules have been rearranged.

-A new ​substance has formed. (Remember a substance is matter that is made of only one kind of atom or molecule)

​

Important info: Matter is never created or destroyed. Atoms cannot be created or destroyed during​ a chemical reaction. The weight of substances will remain the same before and after a chemical reaction. This is because of the law of conservation of matter.
