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

  1. Charles Snikers on

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

    • 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.

        • Leticia Morales on

          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.

        • 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.

    • Praying God take the blinders off your eyes so you can see the marvelous things He has for you. God Bless!

    • Christine Yount Jones on

      Chris, thank you so much for your insightful comments. I know everyone will benefit from your perspective!

  2. 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.)

  3. 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)

  4. Vickie L Miller on

    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!!

  5. Mauren Rivera on

    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.

  6. 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.
