Pour 1/2 cup of water into a saucepan per one 3-ounce JELL-O Gelatin pouch. Pour the contents of the JELL-O Gelatin pouch on top of the water. Allow the mixture to set for one minute. Use at least 3 pouches for a thick consistency that resembles the bars of a bar graph. The more JELL-O pouches and water your use, the thicker the consistency of your bars.
Bring the water and JELL-O powder to a boil on medium heat. Stir the mixture continuously throughout the cooking time until the powder dissolves into the water.
Remove the JELL-O from the heat. Stir 1/3 (2 ounces) of a of frozen juice concentrate per one pouch of JELL-O into the mixture. Add the contents of an entire six-ounce juice can, if using three JELL-O pouches. Stir the mixture until the concentrate melts and dissolves into the water and JELL-O mixture. the juice concentrate helps to thicken the texture of the JELL-O mold.
Line a baking pan such as an 8- by 8- by 2-inch baking pan with tin foil. The smaller the pan, the thicker the volume of your JELL-O bars. Pour the mixture into the pan and cover the pan with plastic wrap. Place the pan in your refrigerator for two to three hours until the mixture gains a firm consistency.
Write a title for your bar graph on construction paper such as "Classroom Favorite Foods," or "Room 101 Favorite Sports," based on the survey question that your graph is representing.
Place a ruler down vertically on your construction paper. Make a mark every two inches for eight inches on the edge of your paper, based on the pan length measurement of eight inches. Count by "2," starting with the number "0" to create your number scale. Write a number next to each mark, starting with "O" at the bottom and ending with "8" at the top. Label the vertical number scale "Number of Students" or "Number of Participants," based on your surveyed demographic.
Place your ruler horizontally on a different piece of construction paper. Divide the width of the pan (eight inches) by the number of choices on your survey so that the bars are are the same distance apart. Make a mark to represent where each choice will be written. Write the survey options given along the edge of the paper. Label "Foods" or "Sports" horizontally under where you write the options.
Take the JELL-O pan out of the refrigerator. Tape the graph title to the top of the pan. Tape the number scale to the left side of the pan and the survey options to the bottom of the pan. Trim the construction paper on all sides, if necessary.
Look at your survey findings. Cut the JELL-O with a serrated knife into vertical rectangular bars that line up with the correct amount on the number scale. Remove excess JELL-O to the sides so that you are left with bars that extend above each survey option. Refrigerate your JELL-O bar graph until presenting it.
