First, the snack:
Cinnamon Honey Roll-Ups with Fruit
1 oz cream cheese, softened
1/2 teaspoon honey
1/8 teaspoon cinnamon
1 tablespoon chopped raisins
1/2 of a banana, diced
1 tortilla, flour or whole grain
1. Stir together cream cheese, honey and cinnamon in a bowl.
2. Add raisins and bananas and stir until combined.
3. Spread over tortilla and roll up.
*Use diced apples instead of banana.
*Use ¼ cup shredded carrot instead of banana. (“Surprisingly good,” reports my 6-year-old nephew.)
Now, the experiment:
Float or Sink Experiment*
Kids love to discover the floaters and sinkers in the colored layers of this fun experiment. Learn about density and liquids by dropping a variety of objects into the liquid layers and seeing where they settle.
Gather these items:
*Water colored with food coloring (any color)
*Large clear plastic container or Mason jar
*Things to drop in: almond or other nut, Legos, grapes, dried pasta, metal nut or other small metal objects, and small tomatoes and anything else you are curious about.
1. Pour honey into the container or jar to a depth of 1.5-2 inches.
2. Slowly add the same amount of vegetable oil to the container.
3. Slowly add the same amount of colored water to the container.
4. Watch as the liquids settle into layers.
5. One at a time, gently drop in the different objects.
Questions to ponder:
Which liquid was the top layer? The middle layer? The bottom layer? Where did the metal objects settle? Where did the Lego float? What about the almond or grape?
Liquids separate by density with the least dense on top. Oil is lightest and floats above water; honey is heaviest and sits below the water. Objects will float or sink depending on how heavy they are. The metal nuts are more dense (heavier) than all the liquids, so they sink to the bottom. The Lego is less dense (lighter) than all the liquids, so it floats near the top. Which other objects ended up floating or sinking?
