Lesson 7 Myth Busters and Green House gasses OPTIONAL LESSON
Pacing 180 minutes (Two 90 minute blocks or four 45 minute periods)
Objective Statement (Intended Learning) Students will be able to identify possible
factors that contribute to global warming. Students will identify human activities that
impact natural resources.
Lesson TEK Objectives
TEKS# Knowledge Skills / Student Expectations Assessment
Science concepts. The student knows the relationship between
structure and function in living systems.
A identify the systems of the human organism and describe their
Science concepts. The student knows that natural events and human BM 6 wks
activity can alter Earth systems.
C make inferences and draw conclusions about effects of human
activity on Earth's renewable, non-renewable, and inexhaustible
What is the greenhouse effect?
Does man contribute to global warming?
What are some human activities that impact natural resources?
Academic: natural resource, renewable, nonrenewable, inexhaustible, Green House
Gasses, Green House Effect, Global Warming
Tier 1: make inferences, draw conclusions, identify
Engage 10 Minutes:
Have students write everything they know about the greenhouse effect and global
warming. (This would be a good journal entry.) Play clip – the green house effect
defined. Have students modify what they have written
Explore: 20 minutes
Pass out work sheet on Myth Busters and explain to the student they will be evaluating an
experiment conducted by Myth Busters. Let them know there will be breaks as they
watch, allowing time to think before answering the questions. The questions will be
answered a section at a time. (20 min) Pass out instructions to greenhouse lab. Go over
lab and emphasize safety.
Evaluate: remaining time
Brainstorm a list of human activities that affect natural resources. Include inexhaustible,
renewable and non renewable resources. This activity can be done using Kagan structures
such as: Rally Table or Simultaneous Round table.
(80 min)From the list created by students assign the following activity.
In pairs choose 3 resources at least one renewable and one nonrenewable.
Select one human activity that may impact each resource. The activity may be the same
for each resource or different for each resource.
Determine the consequences of impact and what if anything needs to be done to reduce or
stop the impact of the activity.
Make a poster to demonstrate what you have determined. Your poster may contain
pictures and or words. (For students with computer access, a power point presentation
may be used. Be sure to be specific on maximum number of slides. This will lengthen the
time needed for the activity by 45 min.)
Principles of Learning:
Organizing for Effort
Self-management of Learning-students will be evaluating an experiment conducted by
Academic Rigor-students will be interpreting new information as they explain human
related issues with global warming. They will be testing their understanding by applying
and discussing concepts
