It is now well known that non-native species have the potential to be harmful to an ecosystem, but that wasn't always the case, and getting rid of non-native invasive species is usually a difficult task. This brief, interrupted case study tells the story of kudzu's introduction into the United States in the late 1800s. It also examines (and even questions) how we define words like "native" versus "non-native" and "invasive" versus "non-invasive." Students will learn how invasive species impact ecosystems and why some non-native species never become established. They also will address questions related to eradicating non-native invasive species. For example, is it okay to attempt to get rid of a non-native species with another non-native species? As part of the activity, students also will have to decide whether or not kudzu should be considered "native" since it has been in the United States since 1876. Originally designed for a general biology course for majors, the case has also been used in a biology class for non-majors as well as an environmental biology class.

"What is Ambitious Science Teaching? Great teaching can be learned. This web site provides a vision of ambitious science instruction for elementary, middle school and high school classrooms. Ambitious teaching deliberately aims to support students of all backgrounds to deeply understand science ideas, participate in the activities of the discipline, and solve authentic problems. We feature 4 core sets of teaching practices that support these goals. These core sets make up the Ambitious Science Teaching Framework. The framework has been based on classroom research from the past 30 years-research that has asked, "What kinds of talk, tasks, and tools do students need in order to fully engage in meaningful forms of science learning?""

The conjugate release pad can perform multiple tasks, the most important of which is uniform transfer of the detector reagent and test sample onto the membrane. The most important function of the conjugate pad is to deliver the detector particles onto the membrane in a consistent volume of sample on every test strip.

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?

Two thirds of the population believes a myth that has been propagated for over a century: that we use only 10% of our brains. Hardly! Our neuron-dense brains have evolved to use the least amount of energy while carrying the most information possible -- a feat that requires the entire brain.
