Activity: Food Preservation Techniques and Recipes: Making Jam

Grade Level:

Time: 40 min

Activity Overview: Making sure to consume all the food that you buy is a fantastic way to reduce waste and save money. There are many simple ways to help you reduce the amount of food you throw away and help you get a little more organized. To start off, you can make a list of the food that you and your family eat on a weekly basis, as well as the food that is more likely to get thrown away. Make sure to check out our activity on Make Your Own Food Diary to get more information on organizing your meals. 

This activity is done best at home but can be incorporated into the classroom through research activities on food conservation.

Make some jam!

Fruits that have been in the fridge or on the counter for a long time can start to look pretty unappetizing. However, unless they begin to develop mold or a weird smell they are still good to eat. 

A fun and easy way to use up those berries in the fridge at the end of the week is to make some jam!

Recipe for easy Blueberry Jam!


  • 2 cups of blueberries
  • ¼ cup of water 
  • ¾ cup of sugar
  • ½ lemon

Step 1: Place a saucepan on the stove and set to medium heat.

Step 2: Pour in blueberries and water then mash about 70-80% of blueberries.

Step 3: Add in sugar and lemon while consistently stirring.

Step 4: Continue stirring on medium to low heat, making sure the jam does not stick to the bottom of the pan.

Step 5: Once the jam thickens to your desired consistency, remove from heat and let cool.

Step 6: Pour into disinfected jars, seal and store in the fridge and enjoy!
