This "DNA Chip Technology" learning object is the from the Sumanas resource series. Sumanas offers a robust selection of content and services that are directed at enhancing the learning experience.

Paul Andersen describes the process of DNA fingerprinting and DNA profiling. He explains how variability in STRs can be used to identify individuals. He explains the importance of DNA fingerprinting in forensics and paternity cases.

Students perform DNA forensics using food coloring to enhance their understanding of DNA fingerprinting, restriction enzymes, genotyping and DNA gel electrophoresis. They place small drops of different food coloring ("water-based paint") on strips of filter paper and then place one paper strip end in water. As water travels along the paper strips, students observe the pigments that compose the paint decompose into their color components. This is an example of the chromatography concept applied to DNA forensics, with the pigments in the paint that define the color being analogous to DNA fragments of different lengths.

Hank imagines himself breaking into the Hot Pockets factory to steal their secret recipes and instruction manuals in order to help us understand how the processes known as DNA transcription and translation allow our cells to build proteins.

The video resource "DNA, Hot Pockets, & The Longest Word Ever: Crash Course Biology #11" is included in the "Biology" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

Paul Andersen introduces the nucleic acids of life; RNA and DNA. He details the history of DNA from Griffith, to Avery, to Hershey and finally to Watson and Crick. He also details the difference between prokaryotic and eukaryotic chromosomes.

Paul Andersen continues his description of DNA and RNA. He begins with the structure of DNA and RNA and moves into the process of DNA Replication. He also describes the central dogma of biology explaining how DNA is transcribed to mRNA and is finally translated into proteins.

Paul Andersen explains how DNA replication ensures that each cell formed during the cell cycle has an exact copy of the DNA. He describes the Meselson-Stahl experiment and how it showed that DNA copies itself through a semi-conservative process. He then explains how multiple enzymes, like DNA polymerase, helicase, primase, ligase, and single strand binding proteins copy DNA.

Hank introduces us to that wondrous molecule deoxyribonucleic acid - also known as DNA - and explains how it replicates itself in our cells.

The video resource "DNA Structure and Replication: Crash Course Biology #10" is included in the "Biology" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

In this video Paul Andersen describes the science practice of data collection. He begins with a brief description of science and the scientific method. He details concepts related to data collection in each of the four big ideas. He then walks through four different practice questions related to data collection.

The Portfolio Manager DataTrends series is the first-ever analysis of aggregate data stored within ENERGY STAR Portfolio Manager, pulled from a pool of hundreds of thousands of commercial buildings across the United States. This fact sheet examines how buildings are tracking not only their energy use, but also their water use in Portfolio Manager. Other statistics are also presented in an easy-to-read format.The resource, "Data Trends: Water Use Tracking" included in "Lesson 4 Water Load Estimations" is a part of "Unit 06 Load Estimations and Calculations" included in Energy & Sustainability ES - Course 3.

A war has been raging for billions of years, killing trillions every single day, while we don't even notice. This war involves the single deadliest being on our planet: The Bacteriophage. The video "The Deadliest Being on Planet Earth - The Bacteriophage" is a resource included in the Biology topic made available from the Kurzgesagt open educational resource series.

In 2015 the bees are still dying in masses. Which at first seems not very important until you realize that one third of all food humans consume would disappear with them. Millions could starve. The foes bees face are truly horrifying - some are a direct consequence of human greed. We need to help our small buzzing friends or we will face extremely unpleasant consequences. The video "The Death Of Bees Explained - Parasites, Poison and Humans" is a resource included in the Ecology topic made available from the Kurzgesagt open educational resource series.

This TED Talk looks at why bees are dying in droves.Why? Leading apiarist Dennis vanEngelsdorp looks at the gentle, misunderstood creature's important place in nature and the mystery behind its alarming disappearance. The resource, "Dennis vanEngelsdorp: A Plea for Bees" included in "Lesson 2 Bee Colony Collapse" is a part of "Unit 09 Biodiversity Decline and Sustainablility" included in Energy & Sustainability ES - Course 4.

Get a clearer idea of what a "Depolarization Wave" means and how it goes from cell to cell through the entire heart! Rishi is a pediatric infectious disease physician and works at Khan Academy.

Students are challenged to design a permanent guest village within the Saguaro National Park in Arizona. The design must provide a true desert experience to visitors while emphasizing sustainable design, protection of the natural environment, and energy and resource conservation. To successfully address and respond to this challenge, students must acquire an understanding of desert ecology, environmental limiting factors, species adaptations and resource utilization. Following theintroduction, students generate ideas and consider the knowledge required to complete the challenge. The lectures and activities that follow serve to develop this level of comprehension. To introduce the concepts of healthy ecosystems, biomimetics and the importance of sustainable environmental design, students watch three video clips of experts. These clips provide direction for student research and challenge design solutions.

Paul Andersen explains how genes control the timing and coordination of embryo development. Seed germination initiates the discussion of cell differentiation. The SRY gene and genetic transplantation shows the importance of embryonic discussion. Cell death is also an important part of development that is regulated by microRNA.

Mr. Andersen talks you through the diffusion demo. After you finish watching this video you should be able to rank the following from smallest to largest: starch, glucose, water, IKI and the pores in the dialysis tubing.

Paul Andersen starts with a brief description of diffusion and osmosis. He then describes the diffusion demonstration and how molecules move over time. He then explains the concepts behind the osmosis lab and how potatoes are affected by increasing sucrose molarity.
