Too hot to go outside? No problem! Bring the water indoors with these fun science experiments...part 2! If you like this craft, you’ll also like our Foam Snakes which use water and dish soap in fun and creative way.

Freezing Water
What You’ll Need:
*Water
*Food coloring, optional
*Plastic container
*Marker

Preparation:
*Discuss: Do you think that the water level will change as it goes from liquid to a solid and back to a liquid again?

Activity:
*Fill the plastic container about three-fourths of the way with water. We added a drop or two of blue food coloring to the water so that we could more easily mark the water level. Mark the water level on the container with a marker.


*Place the container in the freezer overnight. When you take it out, has the water level changed? What if you leave it out to thaw? What do you notice on the outside of the container as it thaws?


Drops of Color
What You’ll Need:
*Water
*2 small bowls
*Food coloring
*Toothpicks
*Medicine dropper, spoon, or straw
*Plate
*Washcloth

Preparation:
*Add a few drops of blue food coloring to one small bowl of water. Add a few drops of red to the other.


*Discuss: What color does red and blue make when mixed together?

Activity:
*Place a few drops of each color on the plate, not touching.


*Use the toothpicks to mix the two colors together. Do they mix?

*Use the medicine dropper or spoon to add more of each color and mix together. How does it look?

*Once the surface of the plate is covered with water, gently lay the washcloth on top of the plate of water. What happens? Lift up the washcloth. Where did the water go?


Water on the Penny
What You’ll Need:
*Penny
*Water
*Eye dropper

Activity:
*Predict how many drops of water can fit on the head of a penny. Now try it. How about if you turn it over? Try this with other coins, too.


Colorful Carnations
What You’ll Need:
*White carnations or daisies
*Scissors/knife
*3 or 4 vases or tall glasses
*Water
*Food coloring

Preparation:
*Grown-ups: Trim the end of each flower with a knife or scissors.

Activity:
*Place a few drops of different colored food coloring into each vase or glass.
*What do you notice happening in just a few hours? By the next day?
*For a really neat trick, take one of your white carnations and very carefully split the stem in half. Now place one stem half in one color water (or leave it in clear water) and place the other stem half in another color. Watch what happens.


*Send us a picture of your kids doing their experiments and we may post it to our site! info@mycalendarmaker.com.
