  • 👉 Example:
    If you mix rice and beans in a bowl, that’s a mixture!
  • 🧪 What is a Mixture?
    A mixture happens when you put two or more different things together.
  • 3. What happens when you mix solids with water?
    Some things float, and some things sink.
  • 2. Can we still see the parts?
    Yes! In some mixtures, you can still see each part, like pieces of cereal and nuts.
  • 🎯
    Summary:
  • And guess what?
    You can usually take the solids out of the water again.
  • 5. Do all liquids mix?
    Nope! Some liquids do not mix at all.
  • 👉
    You can even take them apart again using your hands or a spoon.
  • 👉 For example,
    when you mix drink powder in water, it disappears and the water changes color and taste. That’s called dissolving.
  • Some mixtures are
    hard to separate, like sugar in tea.
  • Not all liquids mix—
    oil and water never mix!
  • 👉 Try putting paper and a stone in water—
    paper floats, but the stone sinks!
  • 👉
    That means it’s an easy mixture to separate.
  • A mixture is when you
    mix things together.
  • 👉 Like food coloring in water—
    it’s gone! You can’t just scoop it out.
  • Once something dissolves,
    you can't take it out again.
  • Some mixtures are
    easy to separate, like cereal and milk.
  • 👉 If you pour oil and water together,
    the oil just floats on top. They stay apart!
  • 4. Do some things disappear in water?
    Yes! Some things dissolve in water.
