This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
This unit covers the classification of living things, including micro-organisms, plants, and animals, based on observable characteristics. It explores reasons for classification and focuses on planning scientific enquiries, recording data, presenting findings, and evaluating scientific evidence.
Lesson Summary
You will learn to carry out and evaluate an investigation to find out about food sources for micro-organisms.
Key Notes
- Yeast consumes sugar and releases carbon dioxide gas as a result. This is called fermentation.
- Scientists control variables to see the effect of changing one variable.
- Fermentation can be observed over time and recorded using scientific diagrams, tables and charts.
- Scientists use the results of their enquiries to make a conclusion that addresses their investigation question.
- Scientists evaluate their investigations by thinking about how well they went and how reliable their results are.
Vocabulary To Learn
- yeast: Yeast is a type of fungus. It is a micro-organism used for making bread.
- carbon dioxide: Carbon dioxide is a type of gas.
- fermentation: Fermentation happens when yeast takes in nutrients from food and releases carbon dioxide and alcohol.
- conclusion: In a conclusion, scientists explain what the results show or mean.
- evaluation: The evaluation of an investigation includes what went well, what could have been improved and whether the investigation question was answered.
Common Mistakes To Avoid
- Pupils may think that a 'fair test' is one in which they all get an equal share in the roles or everyone gets to take a turn.
3 Quick Questions (With Answers)
1. Explain the scientific idea in this lesson using two key points.
Yeast consumes sugar and releases carbon dioxide gas as a result. This is called fermentation. Scientists control variables to see the effect of changing one variable.
2. Define this scientific word and use it in context. 'yeast'
Yeast is a type of fungus. It is a micro-organism used for making bread. Include the word in a full scientific explanation, not as a single label.
3. Correct this common scientific misunderstanding.
Mistake: Pupils may think that a 'fair test' is one in which they all get an equal share in the roles or everyone gets to take a turn. Correction: Explain that both a comparative and fair test are ones in which all variables are kept the same except for the one that is being investigated. This helps to ensure that our results show the effect of just the variable we are investigating.
