The activity begins with students observing different organisms or phenomena and developing questions based on their observations. They then sort their questions into those that can and cannot be answered using the methods of science. Students practice writing scientific questions, designing experiments to address scientific questions, developing questions that involve cause and effect, and understanding the importance of cause and effect questions in scientific research. At the end of the activity, students determine the research questions being asked from reading journal article titles and parts of a published paper or other reported results. Several possible extension activities are provided for continuing the investigation and research of phenomena.

So you have a research assignment. Do you know where to begin? There is so much information out there on the web that it can be hard to know where to start and what path to take through the 'jungle of information'. The Research Safari is designed to help you do just that. Follow the information / inquiry process described here to help you work through your research task. There are also lots of great resources, tools and information that will help give your assignment that WOW factor. The Research Safari will help you to answer the following questions: What am I actually being asked to do for my assignment? What do I already know about the topic? Where am I going to get the information I need? How do I know that the information is accurate or 'authentic' (not fake)? Which are the best websites to use? ​What is the best way for me to present my assignment? How can I make this the best assignment ever?

This "clicker case" tells the story of "Hannah," a baby girl adopted by two loving parents who grows up with an uncontrolled appetite and develops severe early-onset obesity. Students follow Hannah's story as she develops excessive eating early in life, which her health care team is unable to explain. A visit to obesity specialists finally reveals the underlying cause of Hannah's obsession with food: extremely low levels of circulating leptin, a hormone that regulates appetite and body weight. It is further discovered that Hannah's leptin deficiency is due to a mutation in the LEP gene. As the story unfolds, students first work on unit conversions and BMI calculations to practice quantitative skills as well as graph and data interpretation skills. Students then apply their knowledge of DNA transcription, translation, and protein structure to answer questions based on figures from a 2019 study on LEP mutations. The case is best suited for high school and lower-level undergraduate biology courses.

KHULNA, Bangladesh - Flooding is a frequent problem in Chandipur, a village in southwestern Bangladesh. When storms increase the water levels of surrounding rivers, salty water pours in. As a result, farmland throughout the village is ruined, and growing crops becomes harder. The situation became particularly bad after Cyclone Aila hit in 2009. The storm sent salty water surging onto farmlands and it soaked into the soil. After 2009, vegetable crops in Chandipur produced small harvests. Some failed completely.
