-      In this activity, students will learn about a method for surveying wild populations of penguins, will get to practice this method by counting colonies of stuffed penguins using clickers, and most importantly, students will learn about why surveying wild animal populations is important scientific research.
+      A major goal of scientific research is to produce accurate and reproducible estimates of animal populations. In this activity, students learn about a method for surveying wild populations of penguins in remote locations in Antartica. They have an opportunity to try out the method by counting colonies of stuffed animals using clickers. Each student counts an individual colony multiple times to produce as accurate of an estimate 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.  
+      Students learn why surveying animal populations is important for scientific research and what kinds of information can be obtained. Students also learn about the difficulties of producing population estimates through statistical concepts, repeated surveys, and more.

      At our table students are provided with a brief demonstration on how scientists use butterfly counts to study butterfly populations and inform conservation. Students also learn about statistical uncertainty and how increasing the sample size leads to more precise estimates of the butterfly population. The activity can be completed in 3-5 minutes. Participants receive a small insect sticker to take home.

-      With this activity, participants will learn about monarch butterfly biology and how math models can help understand the many threats to their population. Students can examine how the monarch population may increase or decrease through a hands-on modeling experience, which allows users to adjust the amount of plant resources on the landscape, climate conditions, and other environmental variables. Watch the model results appear on your computer screen!
+      The monarch butterfly has been declining across North America for three decades. In this activity, participants learn about monarch butterfly biology and how math models can help understand the many threats to their population. Students examine how the monarch population may increase or decrease through a hands-on modeling experience, which allows users to adjust the amount of plant resources on the landscape, climate conditions, and other environmental variables.

       This activity was created strictly for educational purposes. It is NOT meant to make real-world predictions nor should it be used to inform management. Monarch data (1994-2016) were taken from the annual winter colony counts, collected by the World Wildlife Fund - Mexico.
