Time

15-20 minutes

Description

This object lesson teaches about how important it is to protect our mind from negative influences. It uses a simple visual aid of water and food coloring.

Materials

• Display table
• Red, green or blue food coloring
• Large, clear (see-through) container
• Two or three pitchers
• Enough water to fill each of the pitchers and half the large container
• (Optional) Bottle of bleach

Preparation

· Test the experiment to make sure you know how it works. (Note: if you use too much food coloring, it will be difficult to dilute. A drop at a time is best.)

· Set up the large, clear container (half-full with water) on a display table.

· Have the pitchers and food coloring nearby.

· Practice the script.

Procedure

Use the following script (or modify to suit your needs):

· “Your mind is an incredible creation of God.”

· “It has over 100 billion neurons that send electrical pulses back and forth to each other. These are your thoughts, and you are capable of having more thoughts than the number of known atoms in the entire universe!” (Source: Tony Buzan, Head Strong 2001)

· “Your brain is incredible!”

· “And did you know, that your brain is approximately 75% water?”

· “That’s why I’m going to use this container of water to represent your brain in this lesson.”

· “We will say that this container represents your precious, incredible brain.”

· “The water inside it represents your thoughts.”

· “I have some pitchers of clean water here, and they are going to represent good things that you can put into your brain.”

· “Can anyone help me think of some good things that you can put into your brain?” (Take responses. If the kids need help, try to steer them toward things like Scripture, positive thoughts, encouragement/praise, positive music, learning, worship, thinking about God…)

· “Great, that’s exactly what I’m talking about!”

· “I also have some food coloring up here, and it represents some bad things you can put into your brain.”

· “Who can help me think of some bad things that we could put into our brains?” (Take responses. If the kids need help, try to steer them toward things like profanity, gossip, lies, music with bad lyrics, the Lord’s name used in vain, mean thoughts, self-defeating or limiting talk, hurtful talk, movies or TV with bad scenes, bad pictures, jokes with inappropriate themes…)

· “Exactly! We’ve got to watch out for that kind of stuff!”

· “For this demonstration, I’m going to need a volunteer. Who would like to come help me?” (Select volunteer.)

· “Okay, notice how clear this water is. It’s like our minds the way that God first created them – pure and beautiful.”

· “Let’s say that we are really careful, and we only allow good things into our brain.” (Have volunteer pour some water into container from one of the pitchers.)

· “See what happened? We got more brain!”

· “Okay, it doesn’t work exactly like that, but let’s say that this is like gaining wisdom.”

· “When we add good things, like Scripture, positive thoughts, encouragement/praise… we grow in wisdom and knowledge, and our mind stays clear and clean.”

· “But what if we aren’t so careful, and we allow in some jokes that are hurtful to other people.” (Have volunteer squirt a drop of food coloring into the water in the container. Then pause to allow the children to see the effect. Just one drop of food coloring will spread and spread throughout the water until it has tinted the whole thing.)

· “Wow! Did you see that? Just that one little drop of bad stuff changed the whole color of the water.”

· “And what if we still aren’t so careful, and we allow in some inappropriate pictures (have volunteer add drop) …and profanity (add drop) ….and music with negative lyrics (add drop) …and some negative self-talk about what a loser we are or how stupid we are at math (add drop).”

· “Look what happens then. Our minds are getting darker and darker.”

· “What should we do about that?” (Listen to responses. When someone suggests to add more good things, continue.)

· “Right! Exactly! We need to add more good stuff – more Scripture and positive thoughts and godly advice from our parents…Romans 12:2 says that we should stop doing what the rest of the world does and start being transformed by renewing our minds. That’s the same thing as adding in the good stuff.” (Have volunteer pour in more water.)

· “But do you see the problem I’m seeing?” (Listen for responses.)

· “The water (our minds) are not going back to clear again. We are diluting the bad stuff, but it’s taking a lot more water than it did food coloring to improve our mind here.”

· “That’s the way sin works. Both Jesus and the Apostle Paul warned that, ‘a little yeast works through the whole batch of dough.’ (Matthew 13:33 and 1 Corinthians 5:6)”

· “Yeast is an image of sin in the Bible, so Jesus and Paul are saying that a little sin will spread until it ruins everything.”

· “So, as soon as we realize the damage we are doing to our minds, we’ve got to stop adding yeast / sin.”

· “Then, we’ve got to add lots and lots of good stuff by going to church, hanging out with godly friends, listening to our parents, changing the music we listen to, changing the movies we watch, reading the Bible every day, memorizing Scripture, studying about God…” (As you are mentioning these things, have the volunteer pour more water into the container with each suggestion. Try to fill the container until it’s full – unless you plan to continue with the bleach part of the lesson.)

· “Good habits are going to be the best way to dilute the bad stuff that you already have in your minds.”

· “And it’s not going to be easy. You’re going to have to work at it every day.”

· “And when you allow bad stuff in, it’s going to take much longer to dilute it than it did to let it in there.”

· “It’s like when I eat too much food. It might take me an hour of exercise to burn the amount of calories I ate even though it only took me five minutes to eat it.”

· “Because our minds are so awesome, I don’t believe the bad stuff ever goes away.”

· “I think our brains have the ability to hold onto everything we’ve ever put in there (even though sometimes it’s hard to remember where you left your stuff).”

· “If you put lots of bad stuff in your mind, that’s the bad news. The good news is, that your mind will never be too full of good stuff, so you can keep on adding it in!” (Thank your volunteer, and allow him/her to return to his/her seat.)

Optional Section – Adding Bleach

· “Now, there is one more thing that you can do that we haven’t talked about.”

· “You can give all that bad stuff you put into your mind to God in prayer.”

· “This bleach represents our prayers to God. (By the way, kids, bleach is a powerful and dangerous chemical. You should never handle it unless you have an adult there with you.)”

· “I don’t think the bad stuff we’ve put in our minds ever goes away, but we can turn it over to God in prayer, and He will use it for good.” (Pour bleach into the tinted water. It might take quite a bit of bleach (and you may need to stir it), but it will eventually take the tint out of the water. The result will be a yellowish liquid – not perfect, but no longer tinted with the original colors.)

· “Romans 8:28 tells us that God will use ALL things for the good of those who love Him.”

· “That means that He will even take the bad stuff we’ve done or let into our brains and use it for His glory and His Kingdom.” (Give a personal example.)

· “But, hey! That’s not an excuse to put the bad stuff in there! Your best strategy is to keep the bad stuff out in the first place!”
