Apple Usage
Overview
Overview
Keywords: biotechnological use (fermentation, preservation, oxidation)
Disciplines: biology, home economics
Age level of the students: 7-17
Time frame: dependent on the activity
Partners: the local community, local apple growers, local farmers, local supermarket
Apple yeast
In this lesson, students scientifically investigate how to make yeast from flour and apples. They will also learn about the fermentation process.
Please note that the reaction could take several days depending on the conditions and ingredients used. For example, the temperature will affect the rate at which the yeast grows.
The activity is recommended for students of 11 years and older.
Start with a motivation
- During covid there was a shortage of yeast in the supermarkets. But can we make a bread without yeast?
- We can find a solution on the internet. But is every solution based on scientific facts?
Task for students
- Students prepare an apple yeast. They can read the instructions on a worksheet as PDF here and as word file here.
After the students have prepared their yeast, you can proceed to use the yeast for baking. Here are some ideas on how to bake in class.
Task for students
- Students use the yeast they have prepared before for making a pizza.
- While the pizza is baking, the students can look and complete the H5P interactive video Learning about apple yeast below.
- To get involved with the local community, make the pizza for the whole family or the parallel class.
Next challenge
- Make a sourdough bread and try different recipes that you can find on the internet.
Apple vinegar
In this lesson, students scientifically investigate how to make apple vinegar and discuss its usage. They will also learn about the fermentation process.
Please note that after initially setting up the lesson, the apple vinegar can take two months to mature.
The activity is recommended for students of 7 years and older.
Start with a motivation
- Students taste apple juice and apple vinegar. They describe the taste. They discuss how they are made.
Task for students
- Students prepare their own vinegar.
- Instructions can be found:
- On a worksheet as PDF here and as word file here
- In the H5P file Make your own vinegar timetable below
Next challenge
- After making the vinegar, students can complete the H5P quiz What did I learn making vinegar below.
- Students can observe, taste and check the acidity over the next two months to see what changes are taking place.
After the students have prepared their vinegar, they can bottle it. Here are some ideas how to use it for further exercises like labeling the vinegar bottle.
Task for students
- Students design an apple vinegar label so that the vinegar can be sold at school.
- Students can also research the potential health benefits.
- To get involved with the local community, students can sell the vinegar at the school Christmas market.
You can find the worksheet as PDF here and as word file here.
