Joseph in Canaan
Science Workshop
Summary of Lesson Activities:
The children will learn the story of Joseph. They will then use two experiments to explore how Joseph’s brothers were feeling. They will observe how friction creates heat just like friction in a family can make situations “hot.” They will then observe how carbon dioxide bubbles can be “ignited” and explode when the right object is added to a Diet Coke; similarly, we "explode" when too many annoying things happen to us.
Scripture Reference:
Genesis 37:1-36; 39:1-6b
Memory Verse:
"We know that all things work together for good for those who love God." Romans 8:28a (NRSV)
Key Concepts and Life Application
The children will:
- Identify Genesis as the first book in the Old Testament; locating the story in Genesis.
- Retell the story in their own words – identifying story characters and their feelings.
- Explain how jealousy erupted in Joseph’s family. Learn how feelings can grow inside us and make us feel like we are going to explode.
- Understand that God loves us and is never separated from us, that he is always there to help us through any situation.
Preparation and Supplies:
- Read the scripture ahead of time.
- Gather the materials.
- Bibles – minimally one for every two children.
- Yeah and Boo Melodrama originally written by Steve and Brenda Klusmeyer. Find an adaptation of this melodrama by Cathy Weygandt here.
- YEAH-H-H and BOO-O-O signs, one each on different color cardstock.
- Whiteboard and markers
Friction Experiment
- Styrofoam cups (will need 2 per each group of 3-4 students)
- Sand to fill cups
- Instant read kitchen thermometer with metal probe
- Masking or duct tape
- Optional, egg timer that ticks.
Mentos Geyser Demonstration
- 2-liter Diet Coke (one per class session)
- One tube of Mentos (one per class session)
- Use a test tube or a piece of paper rolled into a tight tube to insert the Mentos into the soda bottle
- Small piece of card stock (size of a playing card) to serve as the "plug"
- Rain poncho for teacher
Filler Materials: Sticky Verse
- Craft sticks: 4 sets of craft sticks. Each set should contain one stick with the following written on:
• We know
• that God
• is always
• at work
• for the good
• of everyone
• who loves him.
Lesson
Opening:
Greet the children and introduce yourself.
Say: Let’s take a quick poll. (You may want to record on the whiteboard.)
Raise your hand if you are the only child in your family. Count.
Raise your hand if you are the oldest child in your family. Count.
Raise your hand if you are the youngest. Count.
Raise your hand if you are somewhere in the middle. Count.
Say: We all know it’s hard to live with brothers and sisters, especially when everyone wants his or her own way. Today, we’re going to see how hot families can get when brothers and sisters start to rub each other the wrong way.
Scripture ~ Where in the Bible?
Distribute Bibles to each child or every two children.
Say: We are learning about Joseph and his relationship with his brothers.
Ask: Where in the Bible would we find this story? (Old Testament, Genesis)
Have the students find the book of Genesis, chapter 37, verse 1, in their Bibles. Make sure it is noted that Genesis is the first book in the Old Testament.
Note: Even though you’ll be telling the story to the students, the exercise of finding the story is still important. We do this every week.
Yeah Boo Interactive Reading
Say: Today, I’m going to read you a different version of this story and you are going to provide some sound effects. I will read a short part of the story. If something good is happening, say “YEAH-H-H.” If something bad is happening, say “BOO-O-O.”
Read the following story, pausing between sections to allow the children to respond appropriately with YEAH-H-H or BOO-O-O). For younger ages, you may want to ask the shepherd to hold up the YEAH-H-H or BOO-O-O signs to guide them.
Use the Yeah and Boo Melodrama originally written by Steve and Brenda Klusmeyer. Find an adaptation of this melodrama by Cathy Weygandt here--scroll down to the Drama Workshop (If link goes dead, use SEARCH on Yeah Boo.)
Say: Earlier we talked about families rubbing each other the wrong way.
Ask: What things in the story about Joseph and his brother show that they rubbed each other the wrong way?
Say: Friction is the term describing two things rubbing against each other. When two people don’t get along, they are said to create “friction.” Today, we're going to do an experiment to see if things really do get hotter when they rub each other.
Friction Experiment
Divide the children into two or more teams of 3-4 children each. You need at least two teams. Give each team 2 styrofoam cups--one of these is filled about 3/4 full with clean sand.
Help each team take the starting temperature of the sand by putting the thermometer probe in the center of the cup (don’t touch the sides). Record each temperature on the white board.
Put the empty styrofoam cup on top of the filled one (rim to rim, not stacked). Use masking tape or duct tape to hold them together. Give each team five minutes to shake their containers. Ask them to be careful not to let any sand escape.
Set a ticking timer to make the competition more suspenseful. You could also play some music. When the time is up, help each team take the temperature of their agitated cup of sand. They can do this by sticking the metal probe straight through the cup and into the sand. The team that creates the most heat in its cup of sand is the winner! (No prizes)
Ask: What caused the sand to get hotter? Accept all answers but get the kids to understand that it was because the sand was rubbing against other grains of sand.
What caused Joseph’s brothers to get hot? Accept answers.
Say: Often, when we get rubbed the wrong way, we get hot! Not physically but emotionally.
When someone bothers you, do you feel hot? Feel like you are going to explode?
Let’s go outside and discuss this further.
Mentos Geyser Demonstration
Here is a link to a short video (Steve Spangler Science) explaining how to do the Mentos Geyser experiment. If this link goes dead you should easily be able to find another.
Take the children outside--make sure it is a space that is safe from cars, etc. And make sure that it isn't too close to anything that you don't want to be splashed! Put on the poncho, if desired.
Hold up the 2-liter bottle of soda.
Ask: Have you ever shaken up a bottle of soda? What happened? Why?
Explain: This bottle of Diet Coke is like the brothers. Inside, the brothers were bubbling! When they saw Joseph coming, they felt like they were going to explode.
Let’s let the Diet Coke represent the brothers. In this tube, I am going to put seven Mentos mints. They represent how the brothers felt about Joseph: Put a Mentos in the tube as you say each of the following:
- Joseph is a tattletale!
- Joseph is spoiled!
- Joseph got a coat and I didn’t!
- Why does Father like Joseph best?
- Why doesn’t Joseph have to take care of the sheep?
- Joseph thinks he’s better than we are!
- Joseph even thinks he’s better than his Father and Mother!
Then they see Joseph coming. They are bubbling inside. They aren’t thinking clearly. They are just reacting. So Joseph comes into their camp and they react!
Ask the children to step back!
Put the cardstock "plug" on top of the tube. Turn it upside down on the Diet Coke bottle opening. Remove the "plug". Be prepared to move back quickly as the Diet Coke shoots into the air!
Ask: How did the brothers explode? Accept answers.
Explain: In our experiment, the bubbles in the soda were attracted to the Mentos. It turns out that Mentos are very bumpy so there are lots of places for the bubbles to form. But the bubbles want to go to the top of the soda and the Mentos wants to go to the bottom. So more and more bubbles keep forming and WHAM! The soda blasts!
The brothers were bubbling too. When Joseph walked into the camp, they reacted. They didn’t think.
Go back inside.
Reflecting/Closing:
Say: Joseph’s brothers were frustrated, jealous, and angry. Just like the sand, Joseph rubbed them the wrong way. Just like the soda, they were feeling the need to explode.
Ask: We all feel that way sometimes. What are some things you can do to remain calm instead of getting hot or exploding? Accept answers. Offer suggestions (talk to an adult or friend, count to 10, go off by yourself).
Say: Because God is with us, we can always turn to him. We can pray. We can read the Bible. We can recite verses that we’ve memorized. All of these things can help us when we are frustrated, jealous, or angry.
Let’s say a prayer asking God to help us when we have trouble controlling ourselves.
Filler Time (Use only if you need it): Sticky Verses
If you have time, use the following to help the children learn the Bible verse.
Divide the class into three or four groups. If using just three groups, remove one set of sticks.
Mix all the sticks up and distribute seven to each team. They will get duplicates.
Have groups arrange the sticks they have in the verse order.
Pick one stick they don’t need (hopefully a duplicate) and pass to group on their right. Play continues until a group has the entire verse in order.
Repeat as necessary.
