11 Lessons You Can Teach With Bubble Gum (Yes, Bubble Gum!)

Graphing Create a graph that shows how many students can blow bubbles vs. how many students cannot. Students who know how to blow bubbles can write a how-to to help peers learn the skill of bubble making. Students who have difficulty can write about how they think a bubble is made. Geometry/3-D Solids  Students examine the shape of the gum out of the wrapper (cylinder or rectangular prism, depending on the brand). They compare the shape of the gum pre-chewed to making a bubble (sphere). Measuring Instruct students to measure the length of the gum before and after being chewed. Have kids stretch their chewed gum out as far as they can and lay it on a piece of wax paper (make sure they have clean hands!). How long can they stretch it? Then, have each student blow a bubble and measure the diameter of it. Once they find the diameter, have them figure out the circumference of their bubbles. Mean, Median, Mode and Range List the students’ circumference measurements on the board and have them figure out the mean, median, mode and range using the numbers listed.

Materials: 1. 3 white carnations 2. Scissors 3. Food coloring 4. 3 small cups 5. Water Steps: 1. First, get the 3 small cups and add 3/4 of the cup with water. 2. Next, in each cup at 8 drops of food coloring of your choice. (Make sure to pour different colors for in each cup to create more multi colorful flowers) 3. Then, snip the last centimeter of the carnations' stem and place each flower in the colored water. 4. Finally, wait for 2-4 days to see the results. Lesson: Transpiration is when plants draw water up through its stem, and , thus, the water evaporates from the leaves' stomata. As the water evaporates, it creates pressure that brings more water into the plant. Since the water had color, it made the flowers become that color.

Materials: 1. A wooden skewer 2. A clothespin 3. 1 cup of water 4. 2-3 cups of sugar 5. A tall narrow glass Steps: 1. First, clip the skewer into the clothespin so that it hangs down inside the glass and is 1 in from the bottom of the glass. 2. Next, remove the skewer and clothespin and put the aside. 3. Then, pour the water into a pan and boil it. 4. Next, pour 1/4 cup of sugar into the boiling water and stir till it dissolves. 5. Then, keep adding more sugar, each time stirring until it dissolves. 6. Next, remove the heat and allow it to cool for 20 minutes. 7. Then, ask an adult to pour the mixture into the jar to the top. 8. Next, submerge the skewer into the glass so it is hanging straight down the miss without touching the sides. 9. Finally, put it somewhere where it would not be disturbed and wait for the sugar crystals grow over the next 3-7 days. Lesson: When you mix water and sugar, you created a saturated mixture, which means that the water could only hold the sugar if it was very hot. As the water cools, the sugar turns into crystals on the skewer.

As fundamental forces go, gravity is pretty weak. It can easily be overcome by air pressure, as this classic demo shows.

Not all shadows are black. The Colored Shadows exhibit is a discovery of the colors hidden in white light. Red, green and blue spotlights shine on a wall. The wall is white because red, blue and green light combine to make white light. These colors are often called the additive primary colors. As you walk (or dance) between the lights and the wall, your body casts three different shadows.
