# Stretch with Data

Match graph values and explore margins of error qualitatively.

## Prepare for Blended Learning

### Before Class

If you feel it's needed, plan a lesson using the getting started material in the app. This will help familiarize you and your students with SPIKE Prime.

Make sure to watch the lesson video on this page.

Read through the student material for this lesson via the link on this page, or in the SPIKE App.

You might want to consider:

- Choosing the right tool(s) and the right place. For example, watching videos, reading a textbook, or preparing for a hands-on experience can easily be done at home. Performing the experiment and collecting data "hands-on" is easier in a classroom setting.
- Using a variety of tools and allowing for broad differentiation. This will increase your students' engagement and improve learning outcomes.
- Providing various methods of virtual collaboration. Here are some examples:
- Videoconferencing
- Blogs, chats, or wall posts
- Digital versions of student worksheets

- Adapting the lesson flow to account for not being a classroom setting throughout the entire lesson. We've provided an example lesson flow below.

- Here are other ways to adapt the lesson flow to your student needs:
- Have your students watch the videos describing what they're about to do. You can point them to the SPIKE App or use the student worksheet URL.
- Use any other material you may have already prepared on the topic.
- Customize the Student Inventor Book to have your students prepare their learning experience and reflect on their findings. (see Additional Resources)
- Use the Lesson Briefs (an easy-to-use lesson overview printable 1-pager) to inspire your students with an open ended challenge. (see Additional Resources)

## Engage

### Before Class, 20 Min.

In this lesson, your students will stream

*pitch*,*roll*, and*yaw*data values to trace a line graph in real time. They'll use this graph to coordinate their movements, matching their streamed data to a pre-recorded graph.The

*pitch*,*roll*, and*yaw*data values describe the tilt angle of an object in relation to its 3 axes:- Pitch - tilt on the y-axis
- Roll - tilt on the z-axis
- Yaw - tilt on the x-axis

Use various materials to engage your students on the topic of

*pitch*,*roll*, and*yaw*data values.

**Ignite a Discussion**

Start a discussion by asking questions related to the lesson. Here are a couple of suggestions:

- What are some ways of determining whether or not a movement is precise?
- How could you graph values to represent real-life movement?

Have your students write down their thoughts as a hypothesis.

## Explore

### In Class, 30 Min.

- Have your students build a yoga ring. They can create their own models, or follow the building instructions in the app to build the Yoga Ring model.
- Explain that this device will record the pitch-roll-yaw angle values for various movements.
- Ask your students to try out their models using the suggested program in the SPIKE App. For the first movement, they'll bring the ring from a font facing position (Hub LED Matrix facing student eyes) to the top of their head (see video).
- Tell them to look at the pitch angle on the graph over time and document what they see.

## Explain

### In Class, 15 Min.

- Allow your students some time to adjust their programs to track other values.
- Have them try to match the second graph, which is preloaded in the line graph, with their movements.
- Make sure they realize that the speed of movement will affect the "shape" of the graph.

## Elaborate

### After Class, 20 Min.

- If your students still have access to their SPIKE Prime Sets, have them complete the tasks from the SPIKE App, to elaborate with hands-on learning, for example:
- The last preloaded graph uses two values at the same time. Your students have to combine both moves into one long stretching session.

- If your students don't have access to their sets, have them complete their Student Inventor Notebook, or assign one of the extension activities suggested below. Most of the extension activities can be done using the data collected during the hands-on session
- Facilitate a sharing session in which your students exchange their thoughts and the results of their experiments. This can be done using whichever method/tool is most efficient (i.e., in-person or online).

## Evaluate

- Give feedback on each student's performance.
- You can use the assessment rubrics provided to simplify the process.

## Assessment Opportunities

**Teacher Observation Checklist**

Establish a scale that meets your needs, for example:

- Partially accomplished
- Fully accomplished
- Overachieved

Use the following success criteria to evaluate your students' progress:

- The students can program a device to log data on a line graph.
- The students can correlate the movement of a physical device to the line graph it's generating.
- The students can explain the concepts of
*pitch*,*roll,*and*yaw.*

**Self-Assessment**

Have each student choose the brick that they feel best represents their performance.

- Blue: I can graph data using the program provided in the app.
- Yellow: I can create my own experiment using a line graph.
- Violet: I can create my own experiment, use a line graph, and draw conclusions from the graph.

**Peer-Assessment**

Encourage your students to give feedback to others by:

- Having one student score the performance of another using the colored brick scale above.
- Asking them to present constructive feedback to each other so that they can improve their performance during the next lesson. This is a great opportunity to use videoconferencing tools or blog posting tools in a blended learning scenario.

## Differentiation

**Simplify this lesson by:**

- Asking your students to recreate the experiment using only the Hub, by holding the Hub in the correct position to do this lesson
- Making sure that your students adjust the suggested program in the SPIKE app to match their model configuration.

**Take this lesson to the next level by:**

- Asking your students to build their own yoga rings
- Having your students record a partner's yoga movements on a graph, share their graphs, then try to replicate each other's movements by following the graph data

## Tips

**Building Tips**

**Coding Tips***Using Streaming Mode*

This lesson is designed to be played in Steaming Mode. In that mode, the data collected by the Hub is streamed directly to your device, and traced in real-time on the Line Graph.

*Main Program*

**Science Data Tips**

Here is an example of the data students can expect from this experiment.

## Extensions

**Math Extension**

To incorporate the development of math skills:

- Using the sample data available for this lesson (or your own data), have your students describe what's happening with regard to movement when the graph shows a straight line, and when it shows a curve.
- Have your students find the math expression under the form y = mx + b for a line portion of their graph, in the sample data or in the data .
- Have your students find these first degree equations (y=mx+b) both manually and using a digital tool.

*Note: This will require additional time.*

**Language Arts Extension**

To incorporate the development of language arts skills:

- Have your students use digital media to explain this lesson and their findings. They could do this by:
- Producing a video
- Posting pictures and comments via a learning management system (if available)
- Contacting with a yoga instructor to research whether a device like the Yoga Ring model could be useful

*Note: This will require additional time.*
