The population projections presented in this publication cover the period 30 June 2008 to 2101 for Australia and 30 June 2008 to 2056 for the states, territories, and capital cities/balances of state.
This issue contains estimates of the resident population of Australian states and territories as at 30 June of each reference year. Estimates up to 2006 are final, based on the results of the 2006 Census of Population and Housing. Estimates for June 2007 have been revised and estimates from June 2008 onwards are preliminary.
In this 15 minute video, Paul Andersen explains how feedback loops allow living organisms to maintain homeostasis. He uses thermoregulation in mammals to explain how a negative feedback loop functions. He uses fruit ripening to explain how a positive feedback loop functions. He also explains what can happen when a feedback loop is altered.
Also included is a concept map, slide show, worksheet and transcript of the video.
Transcript added from YouTube subtitles. You can use this to write your own worksheet or quiz.
Students will investigate potential and kinetic energy, and observe that energy is continually transferred from one object to another between various forms.This module was developed by Christina Owens as part of a Virginia Commonwealth University STEM initative sponsored by the Virginia Department of Education.
"The Prairie Preacher" follows Dr. Dwayne Estes, a botanist who earned his nickname for his passionate advocacy of grassland conservation. Once a child who found solace in nature, Estes now dedicates his life to saving America’s most endangered ecosystem—Southeastern grasslands. Through the Southeastern Grasslands Institute (SGI), he works tirelessly to protect and restore these vital landscapes.

This video explores the decline of southeastern U.S. grasslands over 300-400 years, focusing on the role of Native Americans and natural fires in maintaining these ecosystems. European settlers and agricultural practices disrupted this balance, converting grasslands into forests and farmlands. The result was a significant loss of these vital ecosystems, profoundly altering the landscape
Students apply their knowledge of the water cycle to investigate how annual precipitation patterns are related to geography and biology.
Erik Moore and Krissy Sanderlin of Virginia Beach developed (and are still developing, as it is a work-in-progress) this presentation on hybrid and concurrent instruction is a perfect starting point to create your own presentation for your teachers.
Erik Moore and Krissy Sanderlin of Virginia Beach developed (and are still developing, as it is a work-in-progress) this presentation on management of the hybrid classroom with a Teaching Assistant. It is a great starting point to create your own presentation for your teachers.
Students will investigate block-based programming and if-else statements while also investigating light waves and reflection. Students will learn about block-based programming and create a presentation explaining what they discover throughout their light investigation. Students will present their findings through an interactive presentation.
Science Instructional Plans (SIPs) help teachers align instruction with the Science Standards of Learning (SOL) by providing examples of how the content and the scientific and engineering practices found in the SOL and curriculum framework can be presented to students in the classroom.
Blast a Buick out of a cannon! Learn about projectile motion by firing various objects. Set the angle, initial speed, and mass. Add air resistance. Make a game out of this simulation by trying to hit a target.
Students will download and view a video of a ball traveling with projectile motion. Students will analyze the video to determine the ball's launch angle and launch velocity following the ball's first bounce.

Water is the great architect of Earth and a defining factor for the location and movement of life on this planet. Without water, our world would look very different; without the watersheds which capture, coalesce, move, and recycle water throughout a natural system, human and wildlife habitats would not be the same. Freshwater rivers, streams, and lakes are some of the most heavily utilized and pressured natural systems on the planet; these critical habitats have taken the brunt of negative human actions for years. Now, more than ever, we must learn to safeguard our watersheds for the protection of all life that depends on them.For more information and classroom activities, please visit The Wildlife Center of Virginia and VPM UNTAMED websites.
Explore how hydrophobic and hydrophilic interactions cause proteins to fold into specific shapes. Proteins, made up of amino acids, are used for many different purposes in the cell. The cell is an aqueous (water-filled) environment. Some amino acids have polar (hydrophilic) side chains while others have non-polar (hydrophobic) side chains. The hydrophilic amino acids interact more strongly with water (which is polar) than do the hydrophobic amino acids. The interactions of the amino acids within the aqueous environment result in a specific protein shape.
Generate all hydrophilic (polar), all hydrophobic (non-polar), or random proteins and observe how the protein folds in response to these molecular properties. Explore how the potential energy of the system changes over time to draw conclusions about how proteins develop stable structures.
Proteins carry out the essential functions of life processes through systems of specialized cells. The structure of DNA serves as a code for the production of proteins through the process of protein synthesis. Protein synthesis is a biochemical process that uses information coded in DNA to construct proteins. The central dogma illustrates the flow of genetic information in this process: DNA-->RNA-->Proteins.
