Materials: 1.granulated sugar 2.food coloring 3.stovetop safe container 4. Cream of tartar 5.candy thermometer 6.light corn syrup 7.water 8.adult 9.aluminum foil pan 10.measuring utensils

Steps: 1. First, add one and three forts of sugar in the stove top safe container 2. next, add 1 cup of water 3.then, add half a cup of corn syrup 4.next, add 1/8 teaspoon of cream of tartar 5.then, combine all the ingredients 6. Next, slowly heat the heat the mixture at a low boil while stirring 7.then, keep the mixture add a low boil and please a candy thermometer in the container. 8.next, keep the mixture boiling until the temperature reaches 300 Fahrenheit 9.then, pour the mixture into the foil pan 10.next, add food coloring to the pan and spread the colors 11.finally, let the mixture cool until hardened.

Lesson: This experiment is used in candy making. When you add corn syrup, it prevents the sugar from re-crystallizing. The cream of tartar separates the sugar crystals into glucose and fructose, which are simple sugars. The light that passes through the translucent sugar glass will take the colors from the food coloring you choose

The Feminine Face of Space

Museum of Cosmonauts, 1984 - 2015 

Heat and air movement demonstration 2 of 2. When you light a tea bag on fire, it creates a column of hot air that’s inclined to rise. And when the tea bag becomes light enough, it gets carried along!

If you want to try it yourself, there’s more information here. Make sure you’re using a simple paper teabag that you can unfold into an approximately cylindrical shape–fancy ones, like the pyramids, won’t work. And please take appropriate fire safety precautions! I keep a fire extinguisher handy for these demos.

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.

We grew some cress in box with a lid on it, that had one small hole for light. The result: a beautiful example of phototropism, plants growing and moving towards a source of light.

This is a great activity to try at home with the kids.

Exploring Potential and Kinetic Energy

During a physics unit, have students explore potential and kinetic energy with these five fun experiments that encourage problem solving and play.
