Rationale:<br /> | |||
In this inquiry-based lesson plan, students devise a ‘fair way’ to compare (mostly) physical changes in materials such as cheese and chocolate. They ask and answer questions about how to heat the materials and about using materials of the same size and shape. They also predict how substances may change and observe what actually happens.<br /> | |||
The purpose of the lesson is to both support year 2 work on changing materials and to develop students’ ideas about ‘fair tests’. The activity thus offers an opportunity to assess how well students plan a test and how well they observe change. <br /> | |||
Coping with challenges<br /> | |||
* As a class activity, pupils may benefit from a template (writing frame) to plan; predict and record observations. | |||
* To manage the assessment activity, the teacher may work with a small group while the remainder of the class perform other work | |||
Coping with challenges | * Learning objectives or outcomes (National curriculum reference) | ||
* Say how some everyday materials change when they are heated or cooled (Sc 3 2b) | |||
* Observe heating or cooling to try to answer questions about them (Sc1 1). | |||
Learning objectives or outcomes (National curriculum reference) | * Use what they already know to answer questions (Sc1 2b) | ||
* Recognise when a test or comparison is unfair (Sc1 2d) | |||
Resources:<br /> | |||
An oven and a freezer. Everyday materials such as chocolate, wood, bread, different cheeses, jelly sweets; marshmallow; ice, water. Heat resistant pots or containers, a tray, a knife and a spoon.<br /> | |||
