Persuasive argument: Best car

From OER in Education
Got a new motor? Talk about your investigation like a scientist

Lesson idea. This resource is a teacher's commentary on a discussion around the results of an investigation which involves comparing toy cars rolling down a ramp. This might be used as a stand-alone lesson or be expanded to a longer topic. With differentiation, it can be used with any primary age. At the foundation stage, teachers might focus on developing the language of comparison while discussing shared results. At the top of Key Stage 2, teachers might expect their pupils to develop a fully written argument and refer to their initial hypotheses, data and also the possibility of unreliable data due to their control of variables.

Teaching approach. This activity involving inquiry(ta)aims to develop children’s ability to support their conclusions with evidence. The teacher will model(ta) and encourage the use of the language(ta) that children require to discuss or present their data. The teacher can explain their rationale using the lesson below. (edit)
