Activity Introduction

In this lesson, students will carry out an experiment, document the results, and then use the resulting documentation to communicate their findings to younger students. The lesson gives students a chance to think critically about teaching as a discipline, and about communicating scientific learning to support the wellbeing of their community.

If you are doing this whole unit, we recommend carrying out the first part of this lesson at the start of the unit, so that you have time to observe the results of the experiment while carrying out the other lessons. The second half of the lesson then draws on student learning from the rest of the lessons in the unit to inform their science communication project.

Teacher content information:

SugarByHalf ( promotes action to reduce sugar-related diseases so that we can live better, stronger and healthier lives.

Their message is simple: to reduce added sugar consumption by half. Eating too much added sugar is a key driver of serious health problems including obesity, type 2 diabetes, heart disease, tooth decay, dementia and mental health conditions. A poor diet also puts children behind their peers, impacting their brain development, sleep and ability to learn. Poor diet choices
