Dead Zone Challenge Questions

During which season will dead zones most likely occur?

What is the DEPTH of a dead zone? Why?

What type of water do dead zones form in?

If algae make oxygen and algae bloom or grow out of control then why doesn't this cure the dead zone?

Can algae make oxygen at night?

Parents- grade sheets are being sent home tonight for you to sign!
Please ask your child to show you their current grade.

It is a homework grade when they return it signed.

Thanks!

Activity 9 Group Work

  act 9 Group work ASSIGNMENT DIRECTIONS





Model will be on large white chart paper 

Copy and paste the questions from the directions into a new google doc. 

Complete typing your paragraphs for analysis questions 2 and 5 

Share the google doc with Miss Klein (jklein@stamfordpublicschools.org) 

Make sure you title the doc "Purple Group Table 3 Act. 9 questions" 
Put all group members names on the doc as well. 

Did you complete....

Water Contamination Illustration EXAMPLES

Did you fill in rows for act. 2, 3, and 5 on your summary table?

summary table so far... click here

Did you finish your model for activity 5 Nitrate Lab?

Did you finish your activity 4 practice questions? with the formula?


YOU WILL BE ABLE TO USE YOUR SUMMARY TABLE AND MODELING NOTEBOOK ON THE QUIZ.

SUMMARY TABLE for land, water, and human interactions unit

need help with activity 9 analysis 2 and 5? Check here!

1.     a.)  Changes to the water cycle can affect the environment by if it’s too hot and intense sunlight, evaporation can increase, causing drought.

b.)  Changes to the environment caused by contamination are that contaminants do not change to gas during evaporation. The water is evaporated into the air and the contaminants are left behind.

2.)

a.) Major human impacts on the water cycle are:

·        Greenhouse gases by human activities- global warming- more heat, more evaporation

·        Dam a river- forms a lake and reduces the water

·        Drought caused by removing lots of surface water

·        Extract groundwater- can increase evaporation

·        Melting of glaciers and ice sheets- increased the amount of water in oceans

·        More condensation, more clouds act as a blanket and make the planet warmer

·        More weather events

b. - Major human impacts on water quality are: (aka how humans make water quality poor)

·        Human activities release contaminants such as nitrogen, salts, pesticides, metals, harmful organisms, and even medicines into the water.

·        Agricultural and industry

·        Populations of organisms decrease

·        Agricultural water pollutants: nitrates, phosphates, disease causing organisms, sediments

·        Industrial water pollutants: acids, mining, toxic metals, cleaning solvents  

·        Sediments and erosion from construction on the land

5.) Ways humans can mitigate, or lessen, the impact on Earth’s water is:

·        Use less chemicals- only the ones we need

·        Lessen greenhouse gases released into the air and water

·        Create less pollution

·        Lessen erosion and run off

·        Clean up oil spills and other contamination before it enters water supply

·        Clean wastewater before it reenters environment

·        Reduce water use

this week in science class...

WATER CONTAMINATION QUIZ FRIDAY!!!!

Monday: activity 4 on living indicators- filled in a chart using a formula to determine the number of MSC critters and water quality

HW: finish the two analysis questions and finish water contamination illustration from Friday

How does water get contaminated??? draw the items below for your water contamination illustration due TUESDAY 10/2

• run off over landfills (dissolved solids)

• run off over farms (nitrates, fertilizers, pesticides)

• run off from streets (oil/gasoline)

• dissolved oxygen levels too high or low

• manure/toxic waste- biological contamination

• heavy metals from pipes under ground 

• more MSC = healthy water!
• more pollution tolerant critters = unhealthy water!
•  
• pollution intolerant= MSC= cannot survive in polluted waters


• pollution tolerant: CAN survive in polluted waters
•  Living Indicator: living critter that can survive in a contaminated stream

TUESDAY: 

turn in water contamination illustration 

act. 5 lab on nitrates getting into the water 

WEDNESDAY: 

activity 9 reading and questions 

THURSDAY: 

type out answers/ water cycle and human impact 

FRIDAY: 

Water Quiz
