Mississippi Science ENV.3.4
The Standard
- ENV.3
- Students will discuss the direct and indirect impacts of certain types of human activities on the Earth’s climate.
Enrichment: Determine mathematically an individual’s impact on the environment (carbon footprint, water usage, landfill contribution) and develop a plan to reduce personal contribution.

What This Standard Means
What Students Need to Do
- Students estimate their own water use, landfill waste, and carbon emissions from measurements or records. They calculate totals and make a plan to reduce at least one of them.
What Mastery Looks Like
- A student shows the numbers, units, and assumptions behind each estimate. They choose a specific change, calculate the expected savings, and explain how they will check the result.
Common Misconceptions
- Students may treat electricity use in kWh as carbon emissions without using a conversion factor. They may count recyclable items as landfill waste or claim savings without calculating a starting total.
How to Assess It
- Exit ticket: You take a 10-minute shower at 2 gallons per minute each day. Calculate your weekly water use and how much you would save by cutting each shower to 7 minutes.

Ways to Teach It
Weigh one day's nonrecyclable lunch waste on a kitchen scale, then multiply by five to estimate a school week's landfill waste.
Explain which saves more water: three shower minutes at 2 gallons per minute or two tap minutes at 1 gallon per minute.
Give pairs shower-time and flow-rate cards; have them calculate daily gallons, then swap one card to cut their total by 20%.
Use a sample 600 kWh household bill, divide by three residents, and apply 0.4 kg CO2 per kWh to estimate a personal share.
