Fun Dairy Facts

  • All dairy products come from milk.
  • Dairy products include milk, cheese, and yogurt.
  • Calcium from dairy helps support bones and teeth.
  • Dairy foods can be eaten fresh, baked, cooked, or turned into science activities like butter making.

Why Dairy Matters

Dairy products provide calcium, and calcium is especially important for women and children. The original page highlights that calcium helps strengthen bones, helps prevent osteoporosis later in life, and helps keep mouths healthy.

Parent Note: If a child does not like milk or cheese, it can help to look for other foods that provide calcium and to keep introducing dairy in different ways.

Daily Calcium Needs

Kids' Daily Calcium Needs

  • Birth to 6 months: 210 mg
  • 6 to 12 months: 270 mg
  • 1 to 3 years old: 500 mg
  • 4 to 8 years old: 800 mg
  • 9 to 18 years old: 1,300 mg

What Counts as One Serving of Dairy or Calcium-Rich Foods?

How to Make Homemade Butter

How to Make Homemade Butter

  1. Pour about 1 tablespoon of whipping cream that has been warmed to room temperature into a small jar.
  2. Put the lid on tightly.
  3. Shake the jar continuously. Take turns with family members or friends.
  4. Keep shaking until the cream first turns thick like whipped cream, then forms into a ball of butter.
  5. Pour off the extra liquid and add a little salt if desired.

This is a fun kitchen science activity because kids can watch a liquid change into a solid through movement. The original page explains that shaking forces the fat molecules in the cream to bump together until they form butter, while the remaining liquid becomes buttermilk.

Cream for making homemade butter

Science Tip: This is a great way to show kids that physical movement can change food structure.
Making Butter Science Results: When you shake the jar, you are forcing the fat molecules in the cream to bump into each other repeatedly. Cream is an emulsion, which means tiny fat droplets are suspended in liquid. As the jar is shaken, the protective membranes around the fat droplets break and the fat begins to stick together. This process is called churning. As more fat droplets join together, they form a solid clump of butter and separate from the watery liquid, which is buttermilk. This simple experiment helps kids see how physical movement can change the structure of food and turn a liquid into a solid.

Mini Activity

Compare Dairy Textures

  1. Look at milk, yogurt, shredded cheese, and butter.
  2. Talk about how each one feels and looks different.
  3. Notice which are liquid, soft, or solid.
  4. Discuss how all of them started from milk.

This is a simple way to help kids see how one food source can turn into many different foods.
