Activity Introduction

 

A very practical lesson using sugary drinks to explore the relationship between liquids and solids. The lesson contains two experiments. For the first a stove or electric camping stove is needed.

 

Students begin by watching a video of a person boiling down a soft drink to reveal its sugar content. They then undertake an experiment to find out how a range of five liquids impact substances similar to teeth – eggshells or chalk. This experiment needs to be left overnight. The next day, students record the details of their experiment including their prediction for what would happen and the actual results.

 

Learning Intentions

  • Students understand that sugar is a solid that behaves in certain ways with other solids and liquids
  • Students understand the importance of experiments in food research
  • Students understand the importance of recording research outcomes.

  • … the importance of experiments in food research
  • … the importance of recording research outcomes.

Success criteria: Students can…

  • … observe and participate in an experiment

Teacher content information: SugarByHalf (https://www.sugarbyhalf.com/) 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 choice

Student Worksheet

Thought starter: "In the spirit of science, there is really no such thing as a ‘failed experiment’. Any test that yields valid data is a valid test." - Adam Savage, American special effects designer.

In this lesson, you will be helping your teacher to conduct two science experiments. You will be around hot liquids, so pay attention to your teacher's instructions. 

You can write up the second experiment on the Experiment Record worksheet, which will be provided by your teacher. 

Experiment steps: 

  • For this experiment you will need eggshells or drawing chalk, vinegar, soft drink, lemon juice, orange juice, lime juice, 15 clear glasses or plastic cups, sticker labels, and waterproof textas.
  • Your teacher will divide your class into three groups, and allocate 5 clear glass or plastic cups to each group. Fill each cup with one of the five different liquids - vinegar, soft drink, lemon juice, orange juice and lime juice - and write the type of liquid on a sticker label.
  • Draw teeth
