“Separate Colors in a Fall Leaf”
|
Fall is a beautiful time of year with all the leaves are changing colors.
Children wonder why it happens, so it's a great opportunity to use the power of science to show them the separate leaf colors and to explain how the leaves actually change colors.
What you need:
- Leaves that have changed color
- Small jar (baby food jars are the best)
- Lid for the jar (aluminum foil or plastic wrap if you don't have a lid)
- Rubbing alcohol
- Paper coffee filter
- A shallow pan or tray
- Hot water
- Tape
- A pen
- Plastic knife or spoon
- A timer
What you do:
NOTE: Adult supervision is required for this Activity. Please read all instructions completely before starting. Observe all safety precautions.
1. Collect two or three fairly large leaves. Tear or chop them up and put them into a jar.
2. Add rubbing alcohol to the jar so that you completely cover the chopped up leaves. Use the plastic knife or spoon to grind the leaves into the alcohol and break them up.
NOTE: Rubbing alcohol can be dangerous if mishandled or misused. Please read and follow all warnings on the rubbing alcohol bottle.
3. Loosely cover the jar with the lid (aluminum foil or plastic wrap). Fill the shallow pan with about an inch of hot water and carefully place the jar into the pan. Gently swirl the jar every five minutes and replace the hot water as it cools off.
4. Leave the jar in the water for at least half an hour or until the alcohol becomes colored. The deeper the color of the alcohol the better.
5. While you're waiting, cut a long strip of coffee filter paper. When the jar is ready, remove it from the water and uncover it. Put the strip of coffee filter paper into the jar so that one end is in the alcohol and the other end is outside the jar. Secure the dry end with a piece of tape to the outside of the jar.
6. The colored alcohol will travel up the paper. If you leave the paper in the alcohol for about 90 minutes or so, each color of chlorophyll (as well as other "color" chemicals) will travel a different distance up the paper as the alcohol evaporates. You should be able to see different shades of green, yellow, orange, red, etc, depending on the color and type of leaves you're using.
7. Remove the strip of paper and let it dry by taping it to a plain piece of paper.
Why the Leaves Change Color
During summer, the leaves of trees are factories producing sugar from carbon dioxide and water by the action of light on chlorophyll. Chlorophyll causes the leaves to appear green. Water and nutrients flow from the roots, through the branches, and into the leaves. The sugars produced by photosynthesis flow from the leaves to other parts of the tree, where some of the chemical energy is used for growth and some is stored.
The shortening days and cool nights of autumn trigger changes in the tree. One of these changes is the growth of a corky membrane between the branch and the leaf stem. This membrane interferes with the flow of nutrients into the leaf. Because the nutrient flow is interrupted, the production of chlorophyll in the leaf declines, and the green color of the leaf fades.
If the leaf contains carotene, as do the leaves of birch and hickory, it will change from green to bright yellow as the chlorophyll disappears.
In some trees, as the concentration of sugar in the leaf increases, the sugar reacts to form anthocyanins. These pigments cause the yellowing leaves to turn red. Red maples, red oaks, and sumac produce anthocyanins in abundance and display the brightest reds and purples in the autumn landscape.
The range and intensity of autumn colors is greatly influenced by the weather. Low temperatures destroy chlorophyll and promote the formation of anthocyanins, if the nights stay above freezing.
Bright sunshine also destroys chlorophyll and enhances anthocyanin production. Dry weather, by increasing sugar concentration in sap, also increases the amount of anthocyanin. So the brightest autumn colors are produced when dry, sunny days are followed by cool, dry nights.

“ Arts And Crafts Projects For Children”
toddlers activity art and craft for kid
There are many Arts and Crafts projects for children that are very affordable and very easy to put together. One of the easiest Arts and Crafts projects for children can be used by other family members too. Children can create magnets that look like flip flops if they want to, and the only arts and craft supplies that Mom would have to find are magnets that are formed in a rolled sheet and odd beads and ribbon to decorate the magnet top.
Other Arts and Crafts projects for children will provide them with a way to express themselves on paper. Children can create journals by joining lined notebook paper together and use construction paper and crayons to create a dramatic and very colorful cover for their personal journal. Slots can be cut into the side of the journal and buttons can be fitted through to secure the various sheets together. The buttons will make it very easy for the child to add paper to their journal when they need to.
One of the Arts and Crafts projects for children can be used at birthday parties, or used to create hats for any friend that your child has invited over for a visit. There are sculpting balloons that come with a miniature air pump that will create twisted designs for everyone to enjoy. These twistable balloons are very inexpensive and can provide hours of fun when various animal shapes are formed by the whole crowd. Children enjoy wearing these Arts and Crafts projects because they make superb hats that are ridiculously funny to look at.
Most arts and craft projects for children are based on fun and easy application, but there are many opportunities to create Arts and Crafts projects that are useful sources of reflection of days gone by. Although still fun, these Arts and Crafts projects will also serve to remind parents of how small their children's hand was when they were five years old or any other age for that matter.
There are plaster of Paris mold kits available through many hobby shops that were specifically made to hold the handprint of a child. These molds can be accented in realistic skin colors and covered with a polyurethane coating to protect the molds for many years to come. Wedding couples can use these molds to make wedding memories of joined hands that will last forever.
There are many Arts and Crafts projects for children that can be super-sized and used as wall art or as a sculpture for any room in the home. Some children will use the Arts and Crafts projects offered at a ceramic shop to create dinner plates that have the imprint of the child's hand and some artwork that includes the name and date that the plate was personally crafted. The dinner plates are then fired by the ceramic shop and the Arts and Crafts project will provide a lasting memory that any Mother will cherish for many years to come.
