Take, shape and create
View Sequence overviewStudents will:
- participate in planning and conducting a fair-test investigation.
- make predictions about how easy it will be to change the shape of playdough (its malleability).
- make claims supported by evidence collected during their investigation.
Students will represent their understanding as they:
- record their fair-test investigation using an investigation planner.
- record observation in a data table.
- contribute to class discussions.
In this lesson, assessment is summative.
Students working at the achievement standard (science inquiry) should have:
- made predictions based on their experiences.
- followed investigation procedures and made and recorded observations.
- recorded data using tables and other graphic organisers.
- compared their observations with others, recognising similarities and differences.

Lesson
The Inquire phase allows students to cycle progressively and with increasing complexity through the key science ideas related to the core concepts. Each Inquire cycle is divided into three teaching and learning routines that allow students to systematically build their knowledge and skills in science and incorporate this into their current understanding of the world.
When designing a teaching sequence, it is important to consider the knowledge and skills that students will need in the final Act phase. Consider what the students already know and identify the steps that need to be taken to reach the level required. How could you facilitate students’ understanding at each step? What investigations could be designed to build the skills at each step?

Read more about using the LIA FrameworkIdentifying and constructing questions is the creative driver of the inquiry process. It allows students to explore what they know and how they know it. During the Inquire phase of the LIA Framework, the Question routine allows for past activities to be reviewed and to set the scene for the investigation that students will undertake. The use of effective questioning techniques can influence students’ view and interpretation of upcoming content, open them to exploration and link to their current interests and science capital.
When designing a teaching sequence, it is important to spend some time considering the mindset of students at the start of each Inquire phase. What do you want students to be thinking about, what do they already know and what is the best way for them to approach the task? What might tap into their curiosity?

Show students playdough in a sealed container.
Elicit their questions and ideas about the properties of the playdough through discussion. Record any questions/ideas in the class science journal.
- What do you think the playdough will be like when we take it out of the container?
- How could we change the playdough?
- What would happen to the playdough if we left it out of the container for an hour, a day, or a week?
- What questions might you ask about the playdough?
Introduce the word ‘malleable’: how easy a material is to reshape.
Pose the question: How malleable is playdough when it’s left out of its container?

Read more about using the LIA FrameworkThe Investigate routine provides students with an opportunity to explore the key ideas of science, to plan and conduct an investigation, and to gather and record data. The investigations are designed to systematically develop content knowledge and skills through increasingly complex processes of structured inquiry, guided inquiry and open inquiry approaches. Students are encouraged to process data to identify trends and patterns and link them to the real-world context of the teaching sequence.
When designing a teaching sequence, consider the diagnostic assessment (Launch phase) that identified the alternative conceptions that students held. Are there activities that challenge these ideas and provide openings for discussion? What content knowledge and skills do students need to be able to complete the final (Act phase) task? How could you systematically build these through the investigation routines? Are there opportunities to build students’ understanding and skills in the science inquiry processes through the successive investigations?

Students will test how easy it is to change playdough that has:
- come straight from the container,
- been out of the container for a few hours or days, and
- been out of the container for a few days or weeks.
They will test three different actions/changes (for example scrunching, stretching and bending) on the different types of playdough.
Discuss:
- how students might rate the malleability of the playdough (how easy it is to make it into different shapes), for example easy, hard, impossible
- the level of strength/force that might be required to determine each rating.
Plan the investigation:
- Change the length of time the playdough has been out of the container
- Measure how easy it is to change the playdough
- And leave everything else the Same.
- Brainstorm with students what must stay the same, for example the type of playdough, the amount of playdough, the shape of playdough.
Discuss why it is important to change how long the playdough is out of its container but keep everything else the same.
- Would it be fair if we use different sized balls of playdough? Why or why not?
- Would it be fair if we use different brands of playdough? Why or why not?
Allow students time to brainstorm, test, and record the results of their ideas in collaborative teams.
Use Easy or hard? Resource sheet (or create your own) to record results.

Read more about using the LIA FrameworkFollowing an investigation, the Integrate routine provides time and space for data to be evaluated and insights to be synthesized. It reveals new insights, consolidates and refines representations, generalises context and broadens students’ perspectives. It allows student thinking to become visible and opens formative feedback opportunities. It may also lead to further questions being asked, allowing the Inquire phase to start again.
When designing a teaching sequence, consider the diagnostic assessment that was undertaken during the Launch phase. Consider if alternative conceptions could be used as a jumping off point to discussions. How could students represent their learning in a way that would support formative feedback opportunities? Could small summative assessment occur at different stages in the teaching sequence?

Share the results of the investigation with the class.
- What actions did you use to change the ball of playdough?
- Which ball of playdough was the easiest to change? The hardest? Why do you think that?
- What do you think happened to the playdough the longer it was left out of the container?
Present the following three statements (or claims) to the students:
- Claim 1: The longer the playdough is left out of its container the easier it is to change its shape (more malleable).
- Claim 2: The longer the playdough is left out of its container the harder it is to change its shape (less malleable).
- Claim 3: Playdough gets cracks in it when it is left out of its container (not malleable).
Discuss:
- which claim/s they agree with and why, referring back to the evidence of their investigation to support their thinking.
- what other materials might be similar to playdough, or behave in a similar way. For example bread dough, clay, or even glue.
- how they might use what they have learnt when making their 3D sculptures.
Reflect on the lesson
- add to the class word wall of vocabulary related to malleable.
- review the questions students asked about materials and add any new questions students have.
- re-examine the intended learning goals for the lesson and consider how they were achieved.
- consider how scientists use evidence to make claims.
