This lab has students creating a periodic table using candy. The students receive a series of cards with information regarding the mass, calories, sugar, fat, and protein per piece of a common candy. Students are then given a bag with samples of the candy to provide additional observations of taste, texture, dimensions, color, and other properties.
The students then organize their cards into periodic trends by looking for patterns in the data. Students are asked to have at least three patterns that they use to organize their cards. They affix their end product to a poster paper, and write short reflection.
In addition, to make sure their patterns are complete, they are asked to fill in the holes in their table with "mystery" candies. They must use their patterns to predict the various properties of the "mystery" candy, as well as provide an explanation for how they determined the properties.
I typically have students donate the candy after our Homecoming parade - this tends to bring in a lot of candy for students observing on the sidelines.
There are 42 different candies listed, so plenty of opportunities for students to bring in their favorite. I would not try to obtain all of the candies - I have found success with as few as 20 of the 42, although the more there are, the better.
