MS-ESS2-2 Construct an explanation based on evidence for how geoscience processes have changed Earth’s surface at varying time and spatial scales.
Learning Target
Learning Target
- Understand how the forces of weathering and erosion have changed Earth's surface over time.
Success Criteria
Success Criteria
- Students can differentiate between weathering, erosion, and deposition.
- Students can make observations and infer reasons for the observations.
- Students can state a claim and support it with evidence and reasoning.
Lego Race
Lego Race
- At the beginning of each row students will be given a stack of lego bricks that are connected.
- When the teacher says "Go" the first student will remove a brick and then pass it to the next student.
- The first student will proceed to remove the next brick while the next student will pass it down the row.
- The last student will put all of the bricks together (in any order) as they get them.
- The team that finishes first are the winners!
Questions to Ponder
Questions to Ponder
- How was the Lego Race game like the forces of weathering and erosion and the process of deposition?
- Would you include any other forces or processes in the game?
Stream Table Observation
Stream Table Observation
- Your team will observe the stream table as water is running through it for a five minute period.
- The team will collect data about the occurrences of weathering, erosion, and deposition during the 5 minute period.
- Before the observation you must do a little preparation
As a team...
As a team...
- Determine your roles:
- facilitator - makes sure that the team is on task, settles disputes
- recorder - collects data and makes sure that rest of the team has complete data as well
- materials manager - collects and returns materials for the team
- time-keeper - keeps track of the time during the observation period
- Plan how you will collect the data.
- Make observations and collect data.
- Analyze the data.
Interpreting the Data
Interpreting the Data
- Now that you have your data, discuss the following:
- How would you describe the weathering, erosion, and deposition that you observed during the 5 minute period?
- Describe how time was a factor during the observation (besides the fact that we observed it for 5 minutes.)
As a class...
As a class...
- Compare your data and analysis with the rest of the class:
- meet with two other people from other teams and discuss your team's data and analysis. How is your data similar and different?
CER
CER
- Use your data to construct a response to the following question:
- How did the stream table demonstrate the forces of weathering and erosion as well as deposition?
- You may use your data and previous notes to answer the question.
