Candy counting experiment
Make a "bar graph" with different colored candies. Suitable for 3+.
Hypothesis
editHow many different colors of candy are there in the bag of candy? Do you think there are the same number of each color?
Materials
edit
1+ (small) bags of candy

1+ sheets of paper

1 writing implement
Methods
edit Optional: Draw a graph with the # of rows for each color of candy on a piece of paper
 Line up the candies so that a single color is in each row
 Count the number of candies in each row
Replication
editOptional: Repeat the experiment again with a different bag of the same candy of the same size. This is called a trial.
Results
editFor preschool aged children
editWhich color candy was most common? Which color candy was least common?
Did you eat any candies before the experiment was over? How might that have affected the results?
If you did additional trials, did you get the same number of candies for each color in the second trial?
For primary school aged children
editCalculate the percentage of each color of candy for each bag.
Then calculate the average percentage of each color across all trials.
