: BioMath. Quorum Sensing: Organisms Communicating and Coordinating We live in an ever-changing world.
Many people crave information about those changes. As a result, new means of communicating are continually evolving. People originally relied on word of mouth. With the invention of the printer, newspapers spread information to more people, more quickly. Later, telephones, television, cell phones and the Internet increased both the rate at which people could communicate and the number of people that the information reached. Topics Biology: This unit discusses bacterial growth and communication. Prerequisites Biology: A basic understanding of cell structure and functions along with the Central Dogma would be helpful, but is not necessary. : PS-Future. Invasive Species A Module in Planning for Sustainability About This Module: This module focuses on the role of non-native species in ecosystems.
Students explore local examples of such species, including how and why these species become established in ecosystems. Then, after working through the concept of population growth and competitive exclusion, students work with a hands-on randomized simulation model to explore how the number of individuals of a nonnative (or an exotic) species population might influence the ability of that species to take hold and become invasive, doing damage to the ecosystem. A second deterministic model raises questions about how the spatial pattern of an invasion can impact the effectiveness of efforts to contain or slow invasive spread. Summary of Module Objectives: Lesson 1: The student will be able to define and describe invasive species and identify a local example of invasive species.
Climate Change and Human Impact: Extinction vs. Evolution. Ecosystems and Invasive Species. Niche Partitioning and DNA Metabarcoding. Biology Cycling of Matter. All life is dependent on energy and matter.
Due to this, organisms must obtain energy and matter from other organisms or from the environment around them. By better understanding the flow of energy and cycling of matter in an ecosystem, students can see how organisms make, or obtain biological molecules like sugars, amino acids, proteins, and carbohydrates. Biology Cycling of Energy. HS-LS1-5 Students who demonstrate understanding can: Use a model to illustrate how photosynthesis transforms light energy into stored chemical energy.
HS-LS1-7 Students who demonstrate understanding can: Use a model to illustrate that cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed resulting in a net transfer of energy. Biology Ecosystem Dynamics. HS-LS2-1 Students who demonstrate understanding can: Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.
HS-LS2-2 Students who demonstrate understanding can: Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems in different scales. HS-LS2-6 Students who demonstrate understanding can: Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem. Ecosystems are constantly changing. These changes can be a result of shifting living (predators, competition, and available food) and non-living (shelter, water, and climate) factors within a specific environment.
Exploring Biomass Pyramids. This activity is based on the fieldwork of ecologist Dr.
Mary Power. Students explore the nature of trophic relationships in an aquatic ecosystem by first measuring the biomass of algae and then estimating the number of fish that could be supported based on their understanding of trophic pyramids.

Hummingbird nests often appear in clusters, but for years researchers couldn’t figure out what attracted the birds to certain areas. Turned out the answer was, “good neighbors.” Biologist Harold Greeney was doing fieldwork in Arizona in 2007 when he and his team realized that breeding hummingbirds often clustered around hawk nests. By 2009, Greeney and company were able to report that the hummers nesting close to hawks were actually more successful at raising chicks. Ecology Environmental Letter.
Ecology Ecology Interactions in Action. Concord Consortium. In the fall of 2011, SmartGraphs conducted a randomized experimental trial in 29 Pennsylvania schools.
In 14 schools, 17 experimental teachers used SmartGraphs activities with 49 8th and 9th grade Physical Science classes studying the motion of objects (such as position-time and velocity-time graphs). In the other 15 schools, 18 control teachers taught the same topic using the same textbooks, with 42 Physical Science classes.
This study sought to answer two research questions. A summary of findings is provided below. In October 2013 the Journal of Science Education and Technology published an article about our research on its website; for additional information besides the summary, see the accepted manuscript, Helping Students Make Sense of Graphs: An Experimental Trial of SmartGraphs Software.

Using real scientific data to link daily life to environmental issues and ecological functions in secondary school science classrooms. These case study units engage students in real scientific research that has been published in peer-reviewed scientific journals.

Using the Carbon Cycle Interactive Game in the Classroom - Windows to the Universe. Have students read the Windows to the Universe page entitled The Carbon Cycle.
Introduction: Ask students to (based of the reading) list the places where carbon is found on Earth. As a class, brainstorm why carbon is important and why carbon is sometimes hazardous. Tell students that for this online interactive game, they are all playing the role of carbon atoms. They will travel through the carbon cycle. BUG LYPHE lesson plan. Photosynthesis.

Population Issues & Facts - Population Connection. When Population Connection was founded as Zero Population Growth, or ZPG, in 1968, there were 3.5 billion people on the planet.
Since then, our world population has doubled – with no end in sight. The United Nations projects that world population will reach 9.6 billion by 2050, and nearly 11 billion by 2100. Why does it matter? One in eight people is hungry. More than a billion people live in areas where water is already scarce.
