  1. Have you ever done a tie-dye experiment before?
  2. “Grab the ingredients!” Cassandra exclaimed.
  3. “Get the milk.” I yelled.
  4. Drip drop. Blop blop. Mrs B put the the die in.
  5. Splash. I knocked over the milk.
  6. Have you ever seen dishwashing liquid mixed with milk and food colouring?
  7. Wow. Look at the milk it's so amazing.
  8. Have you ever seen milk perform a dance?
  9. Oooooo aaaaahhhh!!! “look at that.”
  10. Sitting. Waiting. Observing.



Tie-Dyed Milk

Introduction

Liquids like water and milk have a property known as surface tension, due to the cohesive forces of the liquid's molecules. Look closely (you can use a magnifying glass) at the edge of the surface of water in a clear glass. Do you notice how the very edge of the water appears to rise up the side of the glass? That's because the surface tension of the water is actually pulling the water away from the glass inward toward the center of the surface.
Soap will reduce this surface tension. Let's see what happens!

Safety

  • Make sure you have an adult helping you.
  • Do not drink the milk after you have put the food coloring and soap in it!
  • Do this experiment near the sink so that when you're done you don't spill milk and food coloring all over the floor.

Supplies

  • A shallow dish - One that is clear is best, to see what's happening under the surface of the liquid, but a shallow bowl, aluminum pie tin, or plastic or paper bowl will work just fine.
  • Milk - The higher the fat content the better. Half-and-half or whole milk works best.
  • Food coloring - Four different colors will be more colorful.
  • Liquid dish soap.
  • A toothpick or small straw might be helpful, too.


Directions

  1. Pour a layer of milk in the dish about 1/2" (1 cm) deep. Room temperature milk works much better than cold milk, if you have the patience to let it sit for a while.
  2. Carefully put one small drop of each of the four food colors onto the surface of the milk, widely separated, and not in the center of the dish (less is better than more!). Something like this:
  3. Get ready to watch what happens! Very carefully drop one drop of dish soap onto the surface of the milk in the center of the dish. (Be careful not to add the soap directly on top of the food coloring. You may want to dip a toothpick in the dish soap Observations
  • What happens to the food coloring when you first put it on the milk? Why do you think that is?
  • What happens when you add the drop of soap?
  • What direction does the food color move when you first add the drop of soap?
  • What direction does the food color move after the experiment has been running for a while?
  • Does the movement go on forever? What happens?
  • What happens if you add another drop of soap after the colors have stopped moving


When the science experiment has been completed the children will use their Chromebooks to create a piece of procedural  writing using interesting ‘hooks’. These can be any/all of the kinds of hooks we have been learning about.
They include;
*Direct Speech
*Onomatopoeia
*Staccato Sentences
*Rhetorical Questions
Miss D’s Example


  1. “Where are the ingredients?” exclaimed Miss D.
  2. Scurry Scurry went our feet as we get the ingredients.
  3. Equipment out. Ingredients sorted. Bowl ready.
  4. Gurgle gurgle as the milk pours into the bowl.
  5. “Stand back everyone” said Mrs B as she gently DRIP! DROPPED! three colours of food colouring into the bowl.
  6. “Ooooooohh” here comes the dish washing liquid.
  7. WOW! we all shouted as the spiraling effect happened
  1. so that a small drop of soap remains on the end of the toothpick, then touch the drop to the surface of the milk.)

in class we did a tye dye   experiment                  

for science we were amazed 
the milk was a soapy colorful mixer
it looked like it was salty 
and I think that the color was not 
mean 
to be that color it was like a poo brown 
 we also did the science  to be a good learner for hooks 
like the ones above the people in my group were Chelsea  me Brie  
and Cassandra
