FunKids Radio and the RSC have teamed up again, and chemistry superhero K-Mistry has returned to introduce children to the chemistry they can find all around them, in their kitchen!
If you teach primary science, see the headings below to find out how to use this resource:
Children will develop their working scientifically skills by:
- Selecting and planning the most appropriate ways to answer science questions, recognising and controlling variables where necessary, including:
- Observing changes over different periods of time
- Carrying out comparative and fair tests
- Drawing conclusions and raising further questions that could be investigated, based on their data and observations.
- Using appropriate scientific language and ideas to explain, evaluate and communicate their methods and findings.
- Describe how living things are classified into broad groups according to common observable characteristics and based on similarities and differences, including micro-organisms, plants and animals.
Children will learn:
- That bacteria and fungi, including yeast, are examples of micro-organisms and are alive.
- That bacteria play many roles in our everyday lives; children will be able to give examples, including bread and cheese making.
Suggested activity use
This activity provides a useful hook into children looking into micro-organisms, and how they can be beneficial or detrimental, depending on the scenario. Children can explore yeast, and its role in bread making, as well as carrying out a fair test to look at variables that affect the activity of yeast.
Children could also look at the role of bacteria in the decomposition of food, by safely observing how different foods decompose over a period of a few weeks. These activities could be carried out as a whole class, with children working in groups.
You will need yeast and other materials to carry out the investigation into variables affecting yeast’s activity.
You will need different foods and transparent, sealable containers when looking at the rate of decomposition of the foods.
Please take into account any health and safety considerations, particularly with the decomposition of food.
