Steps & Flow

10 min: PPSTT Overview: Watch Video

1.

Engage: Read a graph about ghosts

1.

Engage: Read a graph about ghosts

Students watch ▶ PPSTT…the secret to reading graphs like a scientist #dataliteracy 📈

Student start to fill out the PPSTT details on their worksheets.

  • Cherry picking: selecting specific data to tell a different story than is told by all the data

Have students fill in the details of PPSTT on their worksheet while watching the video. It may be helpful to pause, watch it twice, or poll the class for answers. There will be additional opportunities to add PPSTT details as the presentation unfolds.

5 min: Discovering Patterns

2.

Explore: Finding patterns in graphs

2.

Explore: Finding patterns in graphs

Students find patterns in a graph in the presentation from Google Ngram Viewer .

Students or teacher uses Google Ngram Viewer to make a graph relevant to their interests.

  • Patterns: repeated shapes, data points, or missing data in a graph
  • Trend Line: line indicating the general direction or location of a set of data points
  • Ngram: a sequence of ‘n’ consecutive items in a text

Students can do their own Ngram graphs if you have 1:1 technology or you can do a graph as a class. Emphasize school appropriate words.

10 min: What do the prompts tell us?

3.

Explore: What frames a graph? Prompts

3.

Explore: What frames a graph? Prompts

Students explore all the elements that "frame" a graph, including title, x and y-axis labels, units, scale, source of the data.

Students focus on what prompts are present and how they add to the story of the graph.

  • Prompt: for this unit, a prompt means anything that describes or "frames" the data in the graph, ex. title, x and y axis labels, units, etc.
  • Annotate: add notes to something that describe or comment on the main content

Students annotate their Ngram graphs on the worksheet made in the previous step explaining what the prompts tell them.

4.

Explore: Looking for the odd and unusual features on graphs

4.

Explore: Looking for the odd and unusual features on graphs

Students analyze the scale of the graph, context of the data, fit of lines in the video and presentation to discover how graphs can be deceiving.

Students consider what can be strange about a graph: outliers, limited scales, missing data, anything that does not fit into patterns or trends.

  • Strange: for this unit is something on a graph that is odd, unusual, or deceiving.

Students annotate their Ngram graphs on the worksheet with what might be strange or deceiving.

5 min: What's the story?

5.

Explain: What is our takeaway?

5.

Explain: What is our takeaway?

Students summarize what they learned from analyzing a graph.

Students discuss what claims a graph can support and what claims cannot be supported.

  • Takeaway: the story the graph tells, what we learn from reading the graph

Students annotate their Ngram graphs with a summary of what is important.

5 min: Let's Talk about Trust

6.

Elaborate: Can we trust this graph?

6.

Elaborate: Can we trust this graph?

Students ponder what makes a graph trustworthy or not.

Sources, the amount of data, the context, and additional questions are considered as students decide how much they should trust info in a graph.

  • Trust: how reliable the information in a graph is considering the source of the data, the amount of data, how it was collected and the context it is presented in

Students annotate their Ngram graph with details about how trustworkthy it is.

5 min: Claim, Evidence, Reasoning

7.

Evaluate: Support your story

7.

Evaluate: Support your story

Students use the claim, evidence, reasoning methods to explain what aspects of a graph are trustworthy.

After working through the PPSTT steps students make a claim about their graph, support their claim with evidence drawn from the graph, and connect their evidence to their claim with reasoing.

Students may need some coaching on the CER process. Choose one Ngram graph as an example and work through it with the class.

5 min: Detecting Deception

8.

Extend: How can we apply the PPSTT framework to our lives?

8.

Extend: How can we apply the PPSTT framework to our lives?

Students complete an exit ticket explaining whether they think that graphs can be used to deceive people.

Students use what they have learned about how evaluate a graph and explain whether they think graphs can be used to deceive people.

  • Deceive: intentionally misrepresent data to lead people believe something that is not supported by the evidence

You may want to review the 1980 - 2015 graphs that was on many of the slides and the 1800 - 2020 graph that included science to show students how context can be manipulated to tell a different story.

Steps & Flow

10 min: Review the PPSTT method

1.

Engage: Which graph is more honest?

1.

Engage: Which graph is more honest?

Students engage in a class discussion about which graph represents data more honestly.

Students compare graphs from Lesson 1 with short time scales to a graph that shows a much longer time scale and make claims about what graph is more honest.

There are no correct answers to the questions on the first few slides about the Ngram graphs. The purpose of the introductory activity is to get students thinking about how data can be used in different ways to tell different stories.

10 min: Just the Graph

2.

Explore: Finding patterns in stream flow graphs

2.

Explore: Finding patterns in stream flow graphs

Students practice finding patterns in a graph without a title, units, axis labels, or a source to focus on finding pattern in the graph.

Students watch scientists find patterns on the graphs they just worked on in the video.

  • streamflow: amount of water moving through a stream at a specified time period, measured in this unit in Liters/second.

If students are struggling to find patterns in the streamflow graph on their worksheet, you may want to play the video of scientists finding patterns first to scaffold their success.

15 min: Where does it flow?

3.

Explain: Solve a data mystery using the PPSTT process

3.

Explain: Solve a data mystery using the PPSTT process

Students use streamflow graphs, streamflow tables, photographs, and a map to match the data to the location where it was collected.

Students review the prompts, strange, takeaway and trust steps they learned in Lesson 1 while matching 5 graphs to the locations where the data was collected. Students use a table, a map, and photos to gather additional clues.

Long Term Ecological Research station (LTER)=a location receiving public funds from NSF to monitor biological process, species diversity, and climate over decades to help predict future changes to ecosystems

Students may want to focus on getting the correct answer; however, the worksheet is focused on having them explain how they know their answer is correct. Example statements are provided for the first location. Students can copy this format for other locations or you can create your own answer template.

10 min: Are streams wet?

4.

Elaborate: Support your claims with evidence

4.

Elaborate: Support your claims with evidence

Students use their data handout and what they have learned in class discussion to answer higher-level thinking questions about how data tells a story and wether they should believe their data stories.

Students answer the unit question, "Are streams wet?" By reviewing the data, specifically the graph showing all 5 streams, and finding evidence that supports their answer. They also consider what other information they would need to tell a more complete story about the five sites in the data mystery.

  • perennial: a body of water that has some water in it all year
  • intermittent: a body of water that may go dry for part of the year

Help students conclude that just three years of data is not enough to observe long term trends.

Connection to Research

This unit is sponsored by Dr. Tom Luhring's Aquatic Ecology Lab at Wichita State University. The first two lessons foster student data literacy while introducing students to the broader themes of the research presented in Lesson 3. In Lesson 1, students will learn the PPSTT framework, which teaches students how to analyze graphs and figures. In Lesson 2, students will use real data sets from Long Term Ecological Research Sites (LTERs) and analyze graphs on stream flow. In Lesson 3, students will apply the approaches they learned in Lesson 1 and 2 to Dr. Luhring's work on Kansas streams.

Research Background

Dr. Tom Luhring's lab primarily investigates the legacy of droughts for aquatic systems. His students look at how key players in aquatic systems (microscopic life, fish, amphibians) respond to the return of water following droughts and ultimately determine how ecosystems recover. Dr. Luhring's lab combines lab experiments, field experiments and long-term field-based studies to approach ecological questions.
