Fun with Air - Windsock Craft

Mini Windsock Craft





Here is an arts and craft project that I just recently found in the April 2011 Issue of Family Fun magazine. I think its a good fit for this unit on MATTER. My version is a little bigger and I am using string instead of embroidery floss and a hard plastic straw instead of a chopstick.

Children can have fun with AIR (a gas) by flying their mini windsocks indoors or outdoors!





Materials
  • card stock
  • tissue paper
  • hard plastic straw (or chopstick)
  • scissors
  • glue
  • string, yarn (or embroidery floss)
  • ruler
  • pencil
  • crayons, paint (optional)
 





Directions

  • Measure and cut a 6 inch by 3 inch piece of card stock
  • Measure and cut a 6 inch by 1/2 inch piece of card stock.
  • The students may want to decorate the card stock with crayons, paint, etc.
  • Measure and cut a 6 inch by 6 inch piece of tissue paper.
  • Glue one edge of the tissue paper onto the large piece of card stock overlapping about 1/2 inch. This will be the inside of the windsock.
  • Cut the tissue paper into strips from the bottom up to the card stock.
  • Roll the card stock to form a tube and glue.
  • Attach the ends of the smaller piece of card stock to the non tissue paper end of the tube with glue to form a handle.
  • Thread the string under the handle and tie the string to the plastic straw or chopstick.
  • Have fun flying the mini windsock through the air (a gas) and wind (moving air).





Note: I found the hard plastic straws at Dollar Tree (12 straws for $1.00). They are called "Party Straws".






If you don't have card stock, I think a toilet paper roll covered with construction paper or wrapping paper might work even better.

Balloon Experiment




Materials
  • balloon
  • clean empty recycled soda bottle
  • vinegar (or lemon juice)
  • baking powder
  • spoon
  • safety goggles

Show the students a balloon that is not inflated. Brainstorm ways to blow up the balloon. (blow air into the balloon, fill it with helium, etc.) Discuss that all these ideas are ways to use a GAS to fill up a balloon.
Show the students an empty recycled soda bottle, vinegar and baking soda. Have the students brainstorm ways to use these new materials to blow up the balloon. Have the students predict what will happen when they put vinegar and baking soda into the bottle.














Directions
  • Put on safety goggles.
  • Stretch the balloon to make it easy to inflate.
  • Pour 1 ounce of vinegar into the bottle.
  • Pour 2 teaspoons of baking soda into the balloon.
  • Carefully fit the balloon over the mouth of the soda bottle without letting any baking soda fall into the bottle.
  • After the balloon is completely over the mouth of the bottle, let the baking soda fall into the bottle.
  • Observe the balloon expand! 
  • Have the students explain what happened.

Explanation

When baking soda and vinegar (or lemon) are mixed, they form a GAS (carbon dioxide) that rises up into the balloon and inflates it.

Physical and Chemical Changes of Matter

A physical change is a change of matter from one state (form) to another.

Examples
  • ice cream melting
  • liquid water freezing and becoming solid ice
  • cutting wood
  • clouds forming in the sky 




A chemical change is a change that forms a different kind of matter.

Examples: 
  • baking a cake
  • burning wood
  • a nail rusting
  • photosynthesis




Here's a really cool video from Scholastic on Physical and Chemical Changes of Matter. Plus there is a follow-up online multiple choice test that the kids can take after watching the video.

Properties of Matter

The Properties of Matter are characteristics that can be observed or measured

Some of the properties of matter are:
  • color
  • flexibility
  • hardness
  • strength
  • texture
  • weight
  • volume 
  • mass 
  • density  

Here is a really cute video from Scholastic that teaches kids about 4 of the Properties of Matter. Plus the kids can take an online multiple choice test after viewing the video.

The Properties of Matter covered in this video are:
  • Mass: amount of matter in an object (grams)
  • Weight: pull of gravity on an object
  • Volume: amount of space the object takes up
  • Density: the amount of mass per unit of volume

What is Oobleck?

Bartholomew and the Oobleck: (Caldecott Honor Book) (Classic Seuss)                     

Making Oobleck is a perfect activity when studying Matter because it presents characteristics of a liquid and a solid. Plus, it's an EASY, MESSY, and FUN activity which kids LOVE!

But, what is Oobleck???
Scientists call Oobleck a non-newtonian fluid because it acts like a liquid when you pour it but it acts like a solid when a force acts on it.






Materials 

  • measuring cup
  • 1 cup water
  • 1 1/2 cups cornstarch
  • food coloring (few drops) - optional
  • spoons/mixing sticks
  • plastic containers
  • small zip-lock plastic bag
  • old clothes or aprons (suggested)
  • plastic tablecloth or other covering (suggested)
  • warm water and paper towels (for clean-up)
  • other cleaning supplies as needed
You may need more cornstarch or water than what is listed above. 






Directions

  • Review the states of matter especially liquids and solids.
  • Have children observe and discuss the materials needed for the activity.
  • Pour the cornstarch into the bowl. Observe.
  • Add the water slowly, stir, and mix. Observe.
  • Students can finish mixing the Oobleck with their  hands.
  • Have students describe how it feels and discuss its characteristics.
  • Try to pour the Oobleck into another container.
  • Students could store the Oobleck in a plastic bag to use later.
  • Wash all containers, utensils, hands, etc. 
  • Do NOT put any Oobleck in the drains!




    Follow-up



    • Read Bartholomew and the Oobleck by Dr. Suess.
    • Compare and contrast the Oobleck in the book to the Oobleck the kids made.

    How Many Drops of Water Can Fit on a Penny?

    Materials
    • penny
    • dropper
    • water in a container (small plastic/paper cup)
    • plate/paper towel (optional)






      Directions
      • Have students observe a penny with a hand lens.
      • Have students predict the number of drops of water that can fit on a penny.
      • Use an eye dropper to place drops of water one at a time on the penny until the water runs over the edge of the penny.
      • Record the data.
      • Older children can repeat the experiment a few more times and calculate the average.


      If it is their first time doing this experiment, children will probably be amazed at how many drops can fit on a penny. Most students will underestimate the number.  Water molecules are attracted to other water molecules (cohesion). Molecules near the surface of a liquid pull toward each other. The cohesion of water molecules forms a kind of "skin" on the surface.  A drop keeps its shape because of this surface tension.

      Older students can brainstorm ways to change this experiment. Perhaps use a nickel or quarter. Try the back of the penny. What other ideas can students come up with?

      Another variation of this experiment is to use a cup of water filled to the brim. Have the students predict how many drops of water can fit in the cup without the water spilling over.  Have them use a dropper to add drops of water to the cup. They should count the drops and record their data.


      _________________________________________________________________________


      Let's try another experiment with  cohesion and surface tension.


      Materials
      • water
      • pennies
      • cup
      • plate/pan/paper towel to catch any overflow




        Directions
        • Place the cup on a desk or table with a pan/plate underneath to catch any overflowing water.
        • Fill the cup with water to the rim.
        • Predict how many pennies you can add to the full cup.
        • Slowly and carefully drop a penny into the cup.
        • Continue adding pennies in the same manner until the water spills/overflows.
        • Record the data.





          The water level actually rises above the top of the cup due to surface tension. The surface tension forms a kind of "skin" on the top of the water to hold the water together. Water drops are more elastic than we think!

          Guest Post: A Matter of Air by Ashlee from izzyshare.com

          Help your children understand more about air! Books are a great way to introduce new ideas to children. 


          I Face the Wind does a great job of explaining and illustrating the concept of air.  This book is recommended for pre-k through second grade.  The book also offers experiments you can try out at home. Reading this book to your children would be a great way to help introduce the idea of air.

          Kite Flying is recommend for pre-k through third grade.  This story is about a family who make a kite to fly on a windy day.  This book would be great to read before making a kite with your little ones!  After reading Kite Flying watch the video below.  You could compare and contrast the way kites are made.


              
          This video is a great tutorial for making a basic barn door kite.  The video comes from ActivityTV.com.
          I just recently discovered ActivityTV and was pleasantly surprised by the amount of activities and ideas on the site.  

          Nothing is better than having students actually experiment with concepts themselves. Allow students to take kites, pinwheels, and balloons outside to experiment with the air. 

          I also found a tissue paper kite craft kit from Oriental Trading that would be a great activity for kids to further discuss kites, air, and wind.  The kit comes with enough supplies to make 12 kites. 


          To further a kite theme why not make a kite bulletin board? This bulletin board is from izzyshare.com and features students' poems. This would be a great way to cross the curriculum from science to literature.


          Maybe you have older students who need a bit more of a challenge. This teacher from izzyshare.com incorporated kites into her math lesson by having her students make fraction kites.

          It has been pretty windy lately in the Dallas area. I've seen a few kids with kites enjoying the wind. I may just have to make one myself and head outside!  Hope you feel equipped with some good ideas to teach your little ones about air.

          I mean this in the nicest way possible... Go fly a kite! :)

          Thanks for reading!
          -Ashlee

          Fun with Bubbles

          Bubbles are Matter. They are made of air (gas) and a liquid.



           

          Soap bubbles are globs of air enclosed in a film of soapy water. Children can make bubbles using homemade or store-bought blowers and bubble mixes. As the children wave the soapy wand or blower in the air, they are adding the air (gas) that forms the center of the bubble.







          Let the kids have fun experimenting with bubbles. See who can blow the biggest bubble. See who can blow the longest lasting bubble. Have the kids make different bubble solutions and use different bubble blowers to see which works better. Have the children choose a criteria (biggest bubble, longest lasting, etc.), then predict which mix or blower will work the best. Compare a store bought bubble mix to a homemade mix.





          When the children have finished experimenting with different bubble solutions and bubble blowers, have them draw (and label) a picture of today's activities using the terms: air, gas, and liquid.


          Store-Bought Bubble Mix



          Homemade Bubble Mix Recipe

          • 1 part dishwashing detergent to 10 parts warm water
          To make larger bubbles use more dishwashing detergent.


          Homemade Bubble Blower Ideas
          • drinking straws
          • drinking straws and tape
          • funnels
          • a paper cup with the end removed
          • pipe cleaners shaped into circles

            

          Have fun with bubbles!

          Do molecules attract?

          All matter is made up of molecules. 

          Here's a simple activity to observe if molecules attract.


          Materials

          • water
          • container for water (paper cup, etc.)
          • waxed paper
          • dropper
          • pencil





            Directions

            • Use the dropper to place a few drops of water on a piece of waxed paper.
            • Review the meaning of attract (to pull together).
            • Have students predict if the water molecules will attract each other.
            • Use a pencil to push 2 drops of water together. Do this slowly.
            • Observe how the water drops pull together to form one drop.
            • This attraction of molecules is what holds matter together.

            Create Circle and Bar Graphs

            Combining Science and Math

            Air is made up of gases.
            • 78% nitrogen
            • 21% oxygen
            •   1% carbon dioxide and other gases

            Have the students create a circle graph to display the above data about air.

            Students can make their own graph by hand or they can use Kids' Zone, a wonderful website to make a graph.
            Click here: Kids' Zone - Create a Graph 






            __________________________________________________________________________


            Water (a liquid) freezes at 32 degrees F. or 0 degrees C.
            Water (a liquid) boils at 212 degrees F. or 100 degrees C.

            Have the students create bar graphs to display the above data about the freezing and boiling points of water.
