Using References in your Lab Writeup Make sure you both cite the reference that you use in the body of your text, AND provide a reference list at the end of your writeup. For example, to cite references within the body of your lab writeup: In this lab we examined how different fish like to eat different kinds of algae. The red algae are the largest group of algae (Abbott, 1999). Therefore, we focused on red algae in this lab. Many red algae are quite edible and some of the best known red algae include those that are eaten in sushi (sushiworld.com). Algae are also quite nutritious (Markeley, 2010). Our fish came from tidepools, which are located in the area between high and low tide (Mahon and Mahon, 1994). According to our lab manual (WOU Biology, 2011), our fish were collected during low tide. Reference List:
