4 – CARBON DIOXIDE FROM YEAST

 

Objective
– Discover how yeast works.

Material
– Small glass jar.
– Warm water
– Sachet of yeast.

Time : 15 minutes.

Method
– Pour some warm water into the glass jar.
– Sprinkle with yeast.
– Observe the immediate chemical reaction (this happens very quickly): bubbles of carbon dioxide appear.
– Explain the release of carbon dioxide during fermentation. Draw a parallel with what happens when we bake a cake.
– Talk about other ways carbon dioxide is produced :

Breathing (exchange of oxygen and carbon dioxide in the lungs).

Volcanoes (extremely polluting).

Fermentation of fruit (grapes, apples) and plants (hops) to make wine, cider, beer, etc.

Fire (danger of defective heating appliances).

 

5 – PASTEURIZATION

Objective
– Demonstrate how high temperature kills germs, looking at the case of pasteurization.

Material:Sheet 4 and 5

Time: 45 minutes.

Method
The exercise can be done individually or collectively.
– Ask the pupils to look up “Pasteur” and “pasteurization” in the dictionary.
– Do the exercise.
– Ask the pupils to name some pasteurized drinks (fruit juice, milk, beer, cider, etc.).
– Emphasize that most drinks today have been through a pasteurization process, a system developed by Louis Pasteur :

Beer, cider and fruit juice: these are bottled, capped, then sprayed with increasingly hot water (up to 65-70°C) for twenty minutes and chilled by increasingly cold water.

Milk : this is heated to 85-90°C for 20 to 30 seconds, then chilled.

– Conclude all together that the longer foods are cooked at high temperature, the more germs are destroyed.
– Extend the exercise by explaining that a similar process is used for preserving some solid foods. These are sterilized for more than 3 minutes at 121°C, and the process is called canning.
– The teacher could suggest that pupils do some research on the inventor, Nicolas Appert.

Correction
– Louis Pasteur.
– Pasteur is also famous for the discovery of a rabies vaccine. This dreadful illness is caused by a virus which attacks the brain. Most common in animals, particularly foxes, it can be transmitted to man. Vaccination of dogs and cats is obligatory in some areas of France.
– Revealed word: beverages.
– Airtight / plastic / keep / pasteurized / seconds / preheated / cooled / germs / very high / sterilized / fewer.
– To pasteurize a liquid, it is heated to a very high temperature and then cooled rapidly.
– An opened carton of milk should be stored in the refrigerator / will keep for 2 to 3 days.

 

6 – HOW TO READ FOOD LABELS

Objectives
– Be aware that different types of food keep for different lengths of time.
– Know how to read a food label.

Material
– Food labels.
– Rough book.
– Sheet 6for every 2-4 children.

Time : 1 hour.

Method
– A week beforehand ask the children to find wrappers at home from different kinds of food (frozen food, fresh food, long-life products, etc.).
– On the day of the activity, everyone brings one wrapper.
– Put all the wrappers together and divide them into product types : Dairy products / Fresh foods / Meat and fish / Non-perishable foods / Long-life products.
– One product type is chosen by each group (maximum 2 to 4 pupils).
– Each group is given the pupil’s sheet.
– The sheet should be read all together, and the text explained.
– Each group fills in the sheet for the product type chosen.

Place and type of storage recommended.

Length of storage varies according to the type of food.

– Conclude by emphasizing that food should not be eaten after the use-by date.

 

7 – THE GOOD ADVICE GAME

– Be aware of the importance of food hygiene.
– Learn hygiene basics used in food preparation.

Time : 30 minutes

Method
– Set the scene : “It’s Mum’s birthday. Owen and Amy have a surprise for her: they will prepare the meal themselves ! What should they watch out for ?”
– Everyone together make up a simple menu, from starter to dessert.
– List the ingredients they will need.
– Tell the children that there are germs in all foods and explain how cooking (or not) destroys (or not) most of the germs.
– Ask the children to give advice on the best ways of ensuring that everything is hygienic (take the menu course by course) :

Clean the work surfaces.

Cooking utensils should not be used for different foods without being washed each time.

– Wash hands with hot water and soap before, during and after food preparation.

Wash fresh fruit and vegetables before serving or cooking.

Food to be cooked must be well cooked: timing and temperature are not the same for all foods.

Preparation should be quick. Don’t leave foods out of the refrigerator or lying open for too long. Only get food out just before you need it.

Serve food quickly. If left too long in a warm room, bacteria start to spread.

Leave the refrigerator door open for as short a time as possible.

Do not refreeze food that has been defrosted.

– Each piece of good advice gains a cleanliness point. The winner is Netoon of the class.
– The teacher can examine one or more topics in greater depth, depending on the expectations and capabilities of the children.
