Question 1:
If you mix a spoonful of baking soda and a spoonful of vinegar in a
glass, the mixture will:
A. Bubble and fizz,
because a gas has been created.
B. Turn green.
C. Freeze into a solid.
Question 2:
If you shake up a can of soda pop, it will:
(Note to agents: do this experiment outside!)
A. Turn into slime.
B. Change into ice cubes.
C. Make bubbles that will
fizz out when you open the top (or maybe even explode!).
Question 3:
If you add water to a dry, solid bar of soap, it will:
A. Sprout legs and walk away.
B. Become very slippery,
because the water has combined with the solid soap to create liquid
soap.
C. Turn into cottage cheese.
Question
4: If you combine oil and water in a glass:
A. They will mix together
permanently so you can't tell which is which.
B. The mixture will turn into a
meatball.
C. They will sort of mix
together, but then separate out again so that you can tell them
apart.
And finally,
a science riddle: I'm a solid in the freezer, a liquid on the
counter, and a gas on the hot stove. You can find me in the
ocean and in lakes and streams. What am I?
