Explore why objects float-and how faith makes the impossible
Bible Connect: Matthew 17:14-20
Best for: Ages 6 to 12
Stuff Per Group: Two glass pint jars, an egg, a spoon, 4
ounces of salt, small objects, and water.
The Experiment: Ask: Do you think a single
ingredient, such as salt, can totally change a situation?
Fill one jar with water and carefully place an egg in the water.
What happens? Fill a second jar with water and mix in 4 ounces of
salt to simulate the salt concentration in the Dead Sea. Ask kids
to hypothesize about whether the egg will float in the second jar.
Remove the egg from the first jar and place it in the salt water.
Then experiment with other objects, placing some in tap water and
some in salt water to see what floats in each. Carefully retrieve
the eggs so they’re not wasted.
Scientific Facts: Salt water weighs more than tap
water because it’s more dense. An egg floats in salt water because
the water weighs more than the egg. The Dead Sea is almost 10 times
as salty as the world’s oceans, with salt content at 26 to 35
Talk About It: Ask: Was your guess correct? What
differences did you observe when you placed the objects in the salt
water and tap water? Before this experiment, did you think it was
possible for an egg to float in water? Why or why not? Read the
Scripture. How do you think the disciples felt when Jesus said
faith could move a mountain? When have you had to have faith in
something that seemed impossible?
