Talk and Writing
At this stage in the unit, students will complete the inquiry and application sequences for bread molding—they go both up and down the triangle. This means that they will go through the Predictions and Planning Phase, the Observations Phase, and the Evidence-Based Arguments Phase in one lesson. The tables below show specific talk and writing goals for these phases of the unit.

Talk and Writing Goals for the Predictions Phase |

|---|---|---|
|
Treat this as elicitation and brainstorming (like the Expressing Ideas Phase), but with more directed questioning. |
Now that we have set up the investigation, we want to predict what we think will happen to matter and energy. |
Three Questions Handout Predictions and Planning Tool |
|
Elicit a range of student ideas. Press for details. Encourage students to examine, compare, and contrast their ideas with the ideas of other students. |
Who can add to that? What do you mean by _____? Say more. So, I think you said _____. Is that right? Who has a different idea? How are those ideas similar/different? Who can rephrase ________’s idea? |
Investigation Video (first half) |
|
Encourage students to provide evidence that supports their predictions. . |
How do you know that? What have you seen in the world that makes you think that? |
|
|
Have students document their ideas to revisit later. |
Let’s record our ideas so we can come back to them and see how our ideas change. |

|
Help students discuss data and identify patterns. |
What patterns do we see in our data? How do you know that is a pattern? What about ______ data. What does this mean? |
Class Results Poster Class Results Spreadsheet |
|
Encourage students to compare their own conclusions about the data and evidence with other groups and other classes. |
What about this number? What does this tell us? How is group A’s evidence different from Group B’s data? How do our class’s data differ from other classes’ data? |

|
Make connections between the observations and the data/evidence. |
It says here that our BTB turned colors. What does that mean? You recorded that your bread lost weight. What does that mean? |
Observations Worksheet |
|
Have students consider how their predictions and results compare. |
Let’s revisit our predictions. Who can explain the difference between our class predictions and our results? Who had predictions that were similar to our results? Has your explanation changed? How? |
