OVERVIEW: In this unit students will be learning about natural resources and how these resources provide us with things we need to live. Students will have an opportunity to develop ideas on how to conserve natural resources by reducing, reusing, recycling, and replacing.
CONTENT STANDARD 3.4 – Earth materials provide resources for all living things, but these resources are limited and should be conserved.
GRADE-LEVEL CONCEPT: u Decisions made by individuals can impact the global supply of many resources.
KEY SCIENCE VOCABULARY: natural resources, recycle
CONCEPTS: Need to know about…
SKILLS: Be able to do…
Ø Observing, describing, graphing, and recording properties of paper
Ø Predicting and comparing properties of paper
Ø Communicate observations through writing
Ø Identify different sources and kinds of pollution
Ø Develop ways to conserve our natural resources
Ø We can never run out of natural resources.
If we do not do our part to help conserve our natural resources these resources can become impossible to replace.
There are many earth materials in nature which are “natural resources” . From these natural resources we are able to make things we need in order to live. However, there is a limited supply of natural resources. It is our responsibility to keep our natural resources from becoming depleted. Therefore, we need to conserve these resources. We can do this by reusing, reducing, and recycling.
What are natural resources and what can we do to conserve them?
ESSENTIAL QUESTIONS TO GUIDE INSTRUCTION AND ASSESSMENT:
Ø What are natural resources?
Ø How can we reduce the amount of natural resources we use?
Ø How can we reuse products to extend the use of natural resources?
Ø What can we recycle in order to conserve our natural resources?
Ø How can we replace some of our natural resources?
MATH SKILLS TAUGHT/USED:
TOPICS OR CONTEXT:
LESSON 1: Pre-Assessment
· Students identify what they know about Recycling and Conservation
Day 1: Observation of paper types and completion of chart
· Students will explore some of the properties of different kinds of paper
· Students record observations in an organized table
· Students make predictions on absorbency
Day 2: Experiment #1 – Data Collection
· Students compare different types of paper to find out which one holds the most water
Day 3: Experiment #1 – Data Analysis, Graphing, and Discussion
· Students make a bar graph comparing how many squares of each paper type were needed to absorb 25 mL of water
· Students explain in writing how they came up with results
Day 4: Experiment #2 – Planning – Which Paper Towel Brand is Best?
· Students discuss ways to define the “best” paper product
· Students observe and compare the properties of different brands of paper towels
· Students predict which towel brand will be the most absorbent
· Students plan an experiment to compare different brands of paper towels to find out which brand is the most absorbent
· Students write out steps they will use in the experiment
Day 5: Experiment #2 – Data Collection
· Students perform experiment using written steps (from Day 4)
· Students record data on an organized table
Day 6: Experiment #2 – Data Analysis and Discussion
· Students analyze and report data
· Students explain their conclusion in writing using data to support their conclusion
· Students make a bar graph to record their data
LESSON 8: Embedded Task
Day 7: Communicate Your Learning
· Students write a letter to family member explaining their experiment and the outcome along with recommendation
LESSON 9: Hooray for Trees!
· Students will describe the ways in which trees benefit people
· Students will make pictures or models depicting how trees may be used to improve the human-made environment
LESSON 10: We Need Trees
LESSON 11: Stop the Pollution!
· Students will identify different kinds of pollution
· Students will identify sources of pollution
· Students will discuss and explain why it is important to keep the environment free of pollution
LESSON 12: Reduce, Reuse, Recycle
· Students will make necklaces using recycling paper material.
· Students will understand the importance of the 3Rs—reducing, reusing, and recycling.
