Product Description
In this lab, students investigate the difference between experimental and theoretical probability using a small pack of skittles or m&m’s. Students begin by performing a series of random trials to determine the experimental probability of selecting a particular color candy. Students draw candies at random from their bowl and record the frequency of each color drawn. Then, students express these frequencies as probabilities out of the total number of trials performed in the form of fractions, decimals and percents. To investigate theoretical probability, students record their sample space and then express the frequencies of particular colors out of the total number of candies in the bag in the form of fractions, decimals and percents. At the end of the activity, students are asked to make predictions using these probabilities and are asked to make conjectures about how the experimental probabilities might differ if more trials are performed. This activity lays the foundation of understanding for the Law of Large Numbers and is a great interactive way to reinforce probability vocabulary and the similarities and differences between experimental and theoretical probability. This is a fun activity to incorporate around holidays (like Halloween!).
