4-H Partners with Public Libraries

Monroe County Extension office has partnered with rural libraries Cashton, Kendall, Norwalk, Ontario, and Wilton. We will be providing six different science experiments, one per week throughout the summer. Materials can be picked up at the libraries and some of the materials can be found around the home. Instructions will be in the materials that are picked up and video tutorials will be available.

Please call the libraries to find out when you can pick up the materials.
♦    Cashton (608) 654-5465
♦    Kendall (608) 463-7103

Week 1 – Dry Erase Experiment. Find out how to make your drawing move and dance around!
Watch the video tutorial: https://youtu.be/DTvkR41z1i4

Dry Erase Experiment Instructions:

  1. Draw a simple picture of your choice on the glass (A stick figure is a good one to start with) – Make sure all the lines are touching the way you want them, so they don’t come apart. Also make sure they are not too dark.
  2. Pour water onto the plate or into the bowl slowly to lift the drawing – Tilt the bowl so the water is away from the picture and slowly tilt it back to flat, so the water gets under the drawing and lifts it up.
  3. Swirl the water around to make the picture to dance and move.

Supplied in Package:
•  Dry erase marker

•  Glass bowl, plate or picture frame
•  Water

Week 2 – Juice Box Balloon Car. On your mark, get set, go!
Watch the video tutorial: https://youtu.be/HD7ZHmZSB3U 

Juice Box Balloon Car Instructions:

  1. Start with the wheels, make tiny holes in the middle of each bottle cap. Push bottle caps onto both ends of the toothpick, until in place (2 wheels per toothpick).
  2. Choose a side to be the bottom. Using the tape, tape the toothpicks to the bottom of the juice box. (Be sure not to tape too tight, we want the wheels to spin). Once that is done turn the box over.
  3. Place your balloon onto the short end of your bendy straw. Hold in place using your rubber band, being sure to wrap tightly to seal it to the straw. Tape straw onto the top of your juice box, allowing the long end of the straw to hang off the end of the juice box.
  4. Test your car. Blow into your straw to fill up the balloon. Once it is as full as you want it, let it go. (If the back end of the car comes up, you may need to tape down with a coin or two to add some weight). 
  5. Take a blank piece of paper and make a table with 4 columns and 2 rows to record your distances. Take a ruler, yard stick, or tape measure to measure your distance traveled with your balloon car.

Supplied in package:
•  1 Juice Box
•  1 Balloon
•  1 Rubber Band
•  1 Straw
•  2 Toothpicks

•  4 Bottle Caps (same size and shape)
•  Tape
•  Scissors
•  Coins (just in case you need some weight)

Week 3 – Fireworks in a Jar. The safest way to do fireworks!
Watch the video tutorial: https://youtu.be/FTUGJ4MexKU

Fireworks in a Jar Experiment Instructions:

  1. Fill your jar/glass ¾ of the way full with warm water.
  2. In a separate container, mix 3-4 tablespoons of oil and several drops of different colors of food coloring.
  3. Use a fork to gently mix the oil and food coloring together.
  4. Carefully scoop the mixture out of the container and into the jar/cup and when there is not much left in the dish then pour the rest of the oil food coloring mixture into the jar/glass.
  5. Watch what happens. The food coloring will slowly sink out of the oil and into the water. When this happens, it will expand and begin to mix with the other colors.

Supplied in Package:
•  Clear Cup
•  Food Coloring

•  Warm Water
•  Vegetable Oil
•  Bowl
•  Fork or spoon

Week 4
– Walking Water Experiment. Yes, water can walk!
Watch the video tutorial: https://youtu.be/4oZ5QnxTovQ

Walking Water Experiment Instructions:

  1. Line up all your glasses in a row.
  2. Starting with a glass on the end, fill every other glass with water.
  3. Put a few drops of food coloring in each water filled glass. (You can choose what colors to use, but don’t use the same color twice in a row)
  4. Use the spoon to mix the food coloring in each glass. Use a paper towel to wipe off the spoon in between glasses, so you don’t transfer the colors.
  5. Fold each half sheet of paper towel into a narrow strip about 1 inch wide.
  6. Then fold each paper towel in half lengthwise to form a “V” shape. The V should be only slightly taller than your glass (If necessary, rip or cut a little bit off each end of the V to make it shorter)
  7. Use one paper towel to connect each pair of adjacent glasses. Flip the V shape upside down and put one end in each cup.
  8. Watch what happens and make some observations on what happens. (It may take some time; it is very slow)

Supplied in package:
•  Odd number of cups (at least 3)
•  Food Coloring
•  Paper Towel

•  Water
•  Spoon

Week 5 – Disappearing Eggshell Experiment. It’s magic – no it’s science!
Watch the video tutorial: https://youtu.be/fgGStH1FyFc 

Disappearing Eggshell Experiment Instructions:

  1. Add an egg to a glass jar. I’d recommend choosing a glass jar with a wide mouth, because your egg will swell slightly and may become too large for the jar opening.
  2. Add vinegar. Pour enough vinegar to cover the egg and then a little bit more. The egg will float at first but will sink later.
  3. Look for bubbles.
  4. Put on the lid and let sit for a few days or maybe a week.
  5. Carefully remove the egg from the vinegar. Wash and gently rub off any remaining eggshell.  The shell should wipe away easily, but if it does not, you may need to soak it in more vinegar for another day.

Supplied in Package:
•  Jar/Container with a lid
•  White Vinegar

•  Egg

Week 6 – Gravity Activity With Paperclips Experiment.
Watch the video tutorial: https://youtu.be/QPMRfcAn7b0

Gravity Activity With Paperclips Instructions:

  1. Start by tying some paperclips to pieces of string. Then tie the string onto a small dowel.
  2. Lift up the dowel or the strings so the paper clips hang from the string.
  3. Observe which direction the paperclips point. How about if you tilt the them to one side?
  4. Tape your magnets to one side of your ruler.
  5. Suspend the ruler from two stacks of the stacking materials you are using. (Make sure your magnets are facing down)
  6. Take the paper clips off your dowel.
  7. Take one paperclip and hold it until it’s just suspended below the first magnet. Tape the string in place onto the table or whatever surface you are using. Do this for the rest of your paperclips.
  8. After taping the strings in place below the magnets, remove the ruler and observe what happens.
  9. Now put the ruler with the magnets back above the paperclips. Slowly lift each paperclip toward each magnet until they are suspended again.

Supplied in package:
•  String
•  Small dowel
•  Paperclips
•  Magnets
•  Ruler

•  Scissors
•  Tape
•  Blocks, books or other stacking materials
