-      In this activity, students will learn about a method for surveying wild populations of penguins, and they will get to practice this method by counting colonies of stuffed penguins using clickers. Students will also learn about why surveying wild animal populations is important scientific research.

-      To initiate the activity, teachers/volunteers will set up “penguins colonies” – a.k.a., colonies of stuffed animals – and count how many penguins are in each colony to get an accurate total. Then, students will use a clicker to count the number of penguins they see in each colony. They will repeat the counts 3 times for each colony, then select the best estimate of the total number of penguins for each colony. The students will then add up the best estimate from each colony to find the total number of penguins they’ve estimated to be in the population! Students will count each colony three times, rather than just once, for a few important reasons. A major goal of scientific research is to be accurate and reproducible. The students count each colony three times to make sure they are counting as accurately as possible, accounting for any possible errors they’ve made or penguins they didn’t see the first time around.
+      A major goal of scientific research is to be accurate and reproducible. Through this activity, students will learn important context relating to accuracy and reproducibility of scientific research, such as the concepts of estimation, repeated surveys, and more.
