8 Science Object Lessons for Children’s Ministry

Use these 8 science object lessons for children’s ministry to plug into kids’ curiosity about the way things work–and connect them to God.

With the controversy of evolution versus creationism, we Christians sometimes shun science completely — as though its very existence threatens our faith. So we give science the short end of the stick when it comes to teaching kids about God. By doing that, we miss out on the cool things we can do with simple science. Science has some of the most creative, visual, and impactful ways to involve kids in God’s truth.

Helping kids bridge the gap between concrete experience and abstract thinking can be tough. Through the following eight experiences, though, you can lead kids to discovery — real discovery — about who they are and what God’s plans are for them.

So don your lab coats and protective eyewear. Welcome to the amazing world of science — God style!


Holy Pokes 

Find out what happens when you puncture a bag filled with water.

Materials: You’ll need a 1-gallon resealable plastic bag, a pitcher of water, and four very sharpened pencils. You may want to give each child a resealable bag to try the experiment at home.

Theme: God’s grace
Scripture: Romans 8:28
Age Level: 6 to 12
Prep Time: Five minutes
Activity Time: 15 minutes

You’ll need an extra set of hands to assist with this experiment. Fill the resealable bag with water and seal it.

Hold up the bag and a pencil. Ask, “What happens if you poke a pencil through a bag of water like this? Will the water pour out? Why or why not?”

Say, “Let’s see what happens. I’m going to stick this pencil right through the bag. I hope you don’t get wet!”

Hold the bag right over kids’ heads. Stick the pencil through one side of the bag and out the other, and leave it in place. The pencil will act as a plug so water won’t leak through.

Say, “What do you think will happen if I keep sticking in pencils? Let’s try it with the rest of the pencils to see if it always works.”

Poke the rest of the pencils through the bag in the same manner, leaving them in place. The bag won’t leak.

Ask, “Can you explain why the bag isn’t leaking?”

Say, “The pencils work like a plug to stop the water from pouring out.”

“Sometimes bad things happen in our lives. Kind of like these sharp pencils, they seem to poke right through us and hurt us.”

Read aloud the Scripture. Say, “God doesn’t cause bad things, but he uses even bad things for our good. Like the bag uses the sharp pencils to block the holes so they don’t leak, God takes the bad things in our lives, the things that hurt us, and uses them to help us be stronger.”

Tell about a time when God used a bad thing in your life for good.

Say, “Just like it’s hard to understand why the bag didn’t leak, it’s hard to understand how God can possibly bring good out of some of the bad things that happen to us. Sometimes we don’t understand it for a long time to come, but we can trust that God loves us and is taking care of us.” -Laurie Edwards Lebanon, New Hampshire



This is a messy activity that works best on calm, sunny days.

Materials: Water, Joy dishwashing liquid, clear corn syrup, measuring cups, bowls, straws, string, scissors.

Theme: Human nature
Scripture: Job 8:11-21
Age Level: 6 to 12
Prep Time: 10 minutes (at least 24 hours before the activity)
Activity Time: 30 minutes

Mix 6 cups of water, 2 cups of Joy dishwashing liquid, and 2/3 cup clear corn syrup in a large bowl a minimum of one day before the activity. (The longer the solution stands, the stronger the bubbles will be.)

Have kids each cut a piece of string, varying in length from 1 to 3 feet. Give kids one straw each to cut in half. Have them thread their string through both halves of the straw. Tie the ends of the string together.

Have kids submerge their string and straws in the solution. Then have them carefully lift and open their string using the straws as handles. They can wave their arms in the air to make big bubbles. The key is to form the bubbles with gentle motions. They can even try blowing on the bubbles to make a bubble inside a bubble.

Once kids have made several bubbles, ask, “What was most difficult about making bubbles? Was it easier after you’d made a few? Explain. What made the bubbles pop? Did they turn out bigger or smaller than you thought? What else did you notice about the way they looked?”

Read aloud the Scripture. Ask, “How are people in these verses like or unlike the bubbles? What did you notice about what your bubbles did once they floated away from you? Have you ever been like a bubble and floated away from God? Explain. The bubbles would’ve survived longer if they’d remained in the solution. How does God help us in the same way that the solution would’ve helped the bubbles? How can we make sure we’re not floating away from Jesus this week?”




Making butter is a lot like friendship.

Materials: ½ liter-capacity plastic jar with a secure lid, heavy table cream, measuring cup, salt, crackers, plastic knife.

Theme: Friendship
Scripture: Proverbs 30:33
Age Level: 6 to 12
Prep Time: Five minutes
Activity Time: 30 minutes

Pour 1 cup of heavy table cream and ¼ teaspoon of salt into the plastic jar. Then secure the lid at the beginning of class.

Say, “We’re going to pass this jar around the class today. Each of you will take a turn shaking the jar for a few minutes, then pass it to your neighbor. We’ll do this throughout the class, even when we’re doing other activities. Once you’ve got the jar, it’s your responsibility to shake it until it’s time to pass it on.”

Pass the jar to the first child. Allow kids to shake the jar for a few minutes each. Ensure that every child gets to shake it. The cream will eventually clump, and will finally become butter. Eventually you’ll have a glob floating in leftover liquid. Check the jar every 10 minutes to see how the experiment is progressing. Once the cream has turned into butter, ask, “Why do you think we spent all that time and work shaking this jar? What do you think happened to the cream and salt inside the jar?”

Let kids taste the butter on a cracker. Say, “When you shook the cream, protein and fat molecules stuck together. The more you shook, the larger the blobs of fat and protein became. We ended up with butter!”

Read aloud the Scripture.

Ask, “How is what happened to the cream and salt like or unlike friendship? What do you think ‘twisting the nose produces blood’ means? What are qualities of a good friendship?”

Say, “We’re like the cream in the tub. God wants us to bond with our friends, share our friendship, and spread his love to all we come in contact with. Can you think of ways we can be better friends to one another?”

    This is atrocious. It makes me feel physically sick. GROW UP. Keep religion and science separate and stop teaching our children lies.

      Charles, we’re sorry we’ve offended you!

      Charles, I find this so amusing. You come on to a Children’s Ministry website and get upset that they are talking about Children’s Ministry? Apparently, you have decided that you are God and have the right to tell everyone what they can and cannot do.

      But the difference between you and the real God is the real God gives every person choice. He even created a Charles who disdains Him. So I guess I will stay with the living God who gives us all choice. And our choice is to love God and teach our children just as you do yours. Sorry…but control is demonic and that may explain your need to try to control the people on this site.

        God doesn’t cause bad things? Ummm…have you read Job? Have you read HIS plan for Jesus Christ to die as the lamb. I would like to know which “scripture” you are quoting there when you tell the kids that God doesn’t “cause” bad things to happen. Yes, he does use all of the bad in this fallen world and turns it into good….only for those who love him. But, our God is sovereign over ALL things….good and bad. Satan must ask His permission to do anything. So, you may have good intentions with this lesson….but a BIG RED flag went off for me over that comment….it’s very misleading.

          I don’t think it’s misleading. God didn’t “cause” Job’s pain. You are correct in saying that Satan asked permission, therefore Satan was the cause of the pain. It was not God himself inflicting pain upon Job. He allowed it, but he was not the cause. As for Jesus, He is the son of God. Also, God did not cause this. The sin of the world, man, caused this.

            Thanks for your thoughtful response, Leticia! That’s why we like to ask great questions that get kids and all of us thinking!

          If you read Job you realize God didn’t cause bad things, but allows bad things and yes uses those bad things in His perfect timing for our good.

    I am giving the children’s message at church this week – 9/11. The bag of water and pencils lesson is exactly what I was looking for. As a former teacher, I know that kids these days want/need to see it, hear it, touch it in order to get it. Using science (which is fact based) to help explain religion (which is faith based) is brilliant. Thank you for joining the two. (P.S. I so hope that Charles is being sarcastic.)

    Make sure the pencils are sharp…dull pencils don’t make clean breaks in the bag (at least my second pencil didn’t get it done)

      Great tip, Chris! Thanks for sharing that. We’ll change it in the article too!

    Why would we separate agod and science? God created science. He uses it all the time!

    Thank you so much for this wonderful visual (object lesson). I work with 1st and 2nd grades on a Wednesday evening. Many of my precious ones are not churched, so I desire to show them what the Bible is saying. I am looking for object lessons to help them understand God’s love, mercy and grace; and Christ’s amazing love in giving of His life so I (and prayerfully they) might have life. Thank you for sharing this lesson!!

    Thank you for this, I personally think today in the world we are in, we need our children to remember and keep his world in their heart and mind and what better way than a science demonstration. We tend to forget that God made science he gave the wisdom to people to come up with the science so if I can use this to teach and bring the bible to life so they can remember it when they are going through something bad and pray and say God I know I’m going through this because you are allowing it for a bigger purpose in my life than let’s use what ever tool God has giving us. Didn’t God use parables to teach it’s sort of the same using science to illustrate what God it’s putting in our hearts to teach the children.

    I am always interested in the way people view God I came on here as I am planning a couple of science object lessons and I can say I have learnt so much more. It is always insightful seeing how many and varied are peoples views of God and sin (the bad stuff that happens). The immediate response often is to infer that God is the cause of it. Gods grace is the most astounding thing, He suffers long with man and if it wasn’t for His mercy the bad things would be so much worse than what they are. This is the true message of Job and a perfect representation of Gods grace through the eyes of a man that witnessed trial and triumph in the fullest. Job never once complained but trusted in God through his whole experience, this object lesson and the comments combined create a perfect picture, Thanks.
