Kids’ STEM Workshop: Marble Maze (Push and Pull Physics!)

Put kids and marbles together and you automatically have a great time planned. Add a few lessons about Push and Pull, and you have an experiment in physics that combines fine motor skills, creative design, an understanding of force, and lots of marbles that went home with happy families. We held this program as a our second Workshop in January of 2017.

The skinny: This was a super fun program, although it was one of our shortest ones yet. I talked with the kids for about 15 minutes giving them some background in forces, balance, and push and pull physics. Then, I turned the kids loose on building their own marble runs. It only took the kids 15 minutes to design their own, which was much less time than I expected. In the future, I will try to combine this with a second activity to stretch it out, because I do like these workshops to go for 45-60 minutes. It was budget friendly, with supplies left over for me to do this again during our summer reading program.

Inspiration: I found this idea on Buggy and Buddy Blog. Her photos were so engaging that I thought, “We can try that!”

Cost: About $0.25 per child. I ordered a large box of Wikki Stix from Amazon for $23 (this box should serve 156 children, so we will certainly be doing this project again to go through it all!). I also ordered a large bag of Soak-Proof Foam Dinner plates ($4) so that the kids would have something sturdy to build on, and these plates had high edges. I also purchased three packs of 50 marbles for $1 at the Dollar Tree. We also used tape and scraps of construction paper that we had on hand. Each child received one plate, one marble, three of the Wikki Stix, and free access to the paper, markers, scissors, and tape.

Materials:
Foam Plates
Scissors
Scrap construction paper
Wikki Stix
Tape
Markers
Marbles

STEM at work: Building a marble run on a paper plate, which is meant to be held and moved back and forth to make the marble go on the desired path gives children an opportunity to experiment with physics principals, Newton’s First Law, the force of gravity, and creative engineering through original designs. To keep it focused, I decided to talk about the forces of Push and Pull.

Set up: To keep the kids on track (and not using more supplies than they needed) I took the time to prepare individual bags and place settings for each child. That way we did not have to fight about which color or Wikki Stix each child wanted. In each bag I placed 3 of the Wikki Stix, all in different colors and 1 marble. I set up the tables so that each table had five plates with the prepared bags, and I also pre-cut a piece of blue painter’s tape about 8 inches long and stuck it to the table. That way, each child has the materials they needed. I also pre-cut about 200 strips of paper approximately 1″ by 4″ to use for building arches and guards for their marbles. The paper strips were placed on the tables in pie tins so that the kids could grab them and use them at will.

Resources: I used the book, Give it a Push! Give it a Pull! A Look at Forces by Jennifer Boothroyd.

How it went: I brought all the kids and families into our Storytime/Programming Room. The kids sat on our magic carpet and I started off by placing a toy bus on the table. I asked the kids what the bus was doing. (Correct answer: nothing!) I then gave the bus a push. Now what is it doing? (Moving!) Why? One girl answered, “Because of the wheels!”) Really? I turned the bus on its side and gave it another push which sent it a few feet away. We got to the part that it was moving because I pushed it. I then pulled the bus over to me, and the kids go that it moved because I pulled it. Push=move something away from the force. Pull=moves something closer to the force.

I then took out our book,  Give it a Push! Give it a Pull! A Look at Forces by Jennifer Boothroyd. I try to use a book at least for a few moments every Workshop because it shows that literacy and STEM go together in fostering curiosity! I did not read every page of this book. Instead, I prepared some post-it notes and I placed them on pages where I wanted to ask the kids questions. This helped keep the book engaging, and kids and me asking questions about what we were reading.

After finishing the book, I showed the kids the marble run that I had created, and how they would be tilting the plate to push and pull and marble towards them, or away from them, for the marble to go through its maze. I had the kids count and time me to see how long it would take me for my marble to go through the maze that I had created. (Answer: 6 seconds!)

I then had kids volunteer to bring the tables out from the corner of the room and into the center. One little girl was frustrated with her partners who were not lifting the table and she said, “Why is this table not moving?” I could not help it, and I had to answer as I went to give them a hand, “Because we are not applying enough force”. J I have found out that kids love to help me set up and take down the programming room after a program, and this is an important time for me to build positive relationships with them by thanking them for helping.

With the tables in place, the kids were ready to build! Like I said above, it only took them about 15 mintues to finished their maze. Then, the kids raced each other to see who could make their marble go through the maze fastest. I am getting smarter at this, and after the program I asked the kids to give me back and sandwich bag that held their marble and three Wikki Stix. I can re-use the bag, which cuts down on waste and cost! Some kids wanted to keep their bag, though, so their marble did not get lost on the way home, which was fine.

Another STEM Workshop in the books! Stay tuned for our February Workshops: Human Heart Science and Write Your Name in Computer Code!

 

 

 

Storytime: The “Mitten” Week Two

I try to pick one new folk tale each month and present that story in my Storytime by choosing different books from different authors and illustrators who interpret the basic story each a little differently. In January, we are learning the folk tale, The Mitten. I have noticed that the kids enjoy knowing at least one of the stories as the month goes on, and I am able to layer in more interaction (ask the kids to join me in telling the story, acting it out, repeating after me, and making predictions) because the kids know what is going to happen. This lesson plan shows our second week on the folk tale, The Mitten.

Kids’ STEM Workshops: Marshmallow Igloos!

With snow on the ground and Wisconsin suffering from a cold snap, it was the perfect night to talk about how Inuit people build houses with nothing by the natural materials their environment gives them: snow and ice. And, what better way to learn about it than by experimenting with geometric shapes to build igloos of our own…in the comfort of the heated library with marshmallows and toothpicks as our building materials of choice!

The skinny: This was a wonderful winter themed STEM program, and it brought in working with 3-D geometric shapes, which is a program that I had not done before. We had many families attend, which was surprising since they it was January and many families were still out of their normal routine with December not so far in the past. But come they did!

Passive Program: Gingerbread Imaginative Play Station

gingerbread-station

In December, we wanted to offer something different. Enter “Gingerbread Imaginative Play Station”!

I purchased a play dough mixer from Amazon for $25. Then, I went to the dollar store and bought two cookie trays, two spatulas, a bag of googly eyes, and Christmas colored pom-poms. I then went to Walmart and bought two Gingerbread Men cookie cutters. One of my fellow librarians offered to help trace out the cookie cutters on brown paper, and cut them out. We cut out 100 gingerbread men to start with, and I placed a bowl of glue sticks on the table. The kids loved this station, and I even had high school students come in and make one because they said, “It was so cute!”
