Of all the science object lessons I do, this is one of my favorites. Not only does it have an unexpected result, but the visual makes the lesson stick in the memories of children long afterwards.
What do you need: Graduated Cylinder (Or a tall clear container), dark Karo® syrup, vegetable oil, water, red food coloring.
Preparation: Mix a few drops of red food coloring into the water, making the water turn red.
Spiritual Connection: Salvation found in Jesus.
(Pour the dark Karo® syrup into the cylinder.)
God’s word tells us that all have sinned. When we think of sin, we think of someone walking in darkness and not in the light. When we are walking in sin, we are disconnected from God because He is light. We cannot be in the light and be walking in darkness at the same time.
When we are walking in sin, we find that we get stuck in the muck of sin. Just like this syrup is sticky and gooey, sin can be like this. It can stick to us. It can make it hard for us to escape. We may try to escape the trap of sin. But the harder we try, the more we realize how stuck we are. We need someone to rescue us from the pit of sin.
(Pour the vegetable oil into the cylinder. It will rest on top of the syrup.)
We can try to rescue ourselves. We can try to get close to God. We can go to church. We can read our Bibles. We can give money to the church. We can try really hard to be good. We can do nice things for people. None of those things, however, will connect us to God. None of those things will work. We cannot save ourselves from sin.
God is holy and pure. He cannot be next to sin. So how can we be saved from sin?
(Pour the red water into the cylinder. It will slowly move in between the vegetable oil and the syrup. Allow it to continue to sit and the difference in the three layers will become more pronounced. )
When we ask Jesus to forgive us our sin, his blood covers the sin. Only through Jesus can we be forgiven and be put into a right relationship with God.
“Therefore, my brothers, I want you to know that through Jesus the forgiveness of sins is proclaimed to you.”
