Transcript and Presenter's Notes

Title: The student will demonstrate an understanding of Earth and space systems


1
The student will demonstrate an understanding of
Earth and space systems
  • TAKS Objective 5

2
Predict the results of modifying the Earths
nitrogen, water and carbon cycles
  • TEKS 8.12 C

3
The student will predict the results of
denitrification, volatilization, leaching,
runoff, nitrification, and immobilization of
nitrogen
  • Lesson Objective

4
True of False Humans use nitrogen from the
atmosphere to make proteins.
  • Question

5
Humans cannot use N2 and must obtain nitrogen by
eating plants or by eating animals that have
eaten plants.
6
1. Describe the components of the atmosphere,
including oxygen, nitrogen, and water
vapor2. make inferences and draw conclusions
about effects of human activity on Earths
renewable, non-renewable, and inexhaustible
resources.
  • Prior Knowledge

7
  • The Fate of the Nitrate

?EXPLORE
Get ready to play the Nitrogen Game. Lets talk
about the rules of the game.
10
The object of the game is to transform to
ammonium salts (NH4) and nitrate (NO3-) in a
journey toward the green zone, crop uptake. Look
out for the chutes which represent loss of
nitrogen.
11
Form groups of 3 players representing three type
of organic nitrogen (legume nitrogen, crop
residue nitrogen, and manure nitrogen). You will
need one game board and a spinner or dice.
12
Spin or throw the dice. The player with the
highest number goes first and play proceeds in a
clockwise direction. Each player spins or rolls
the dice moving the corresponding number of
squares (no diagonal moves). Two or more players
may land on the same square. If a player lands at
the base of a ladder, move up. If a player lands
at the top of a chute, they slide to the bottom.
You must roll or spin the exact number to win.
The first player to arrive at Crop Uptake (square
25) is the winner.
13
?EXPLAIN
1. How does nitrogen enter the cycle? 2. How is
nitrogen lost from the soil? 3. How is nitrogen
returned to the atmosphere? 4. How does nitrogen
get into the human body?
14
?ELABORATE
Use diagrams of the nitrogen cycle or visit the
following website to view Figures 1 and/or 2
which show diagrams of the nitrogen cycle.
Compare the diagrams to the game. How are they
the same? How are they different? http//muextensi

?EVALUATE
After participating in the nitrogen cycle game,
the student will predict the results of, one of
the following nitrification, denitrification,
volatilization, leaching, runoff, and
immobilization on the environment in a 200-word
essay.
