In this lesson, the students look at the components of cells and their functions. The lesson focuses on the difference between prokaryotic and eukaryotic cells. Each part of the cell performs a specific function that is vital for the cell's survival. Bacteria are single-celled organisms that are very important to engineers. Engineers can use bacteria to break down toxic materials in a process called bioremediation, and they can also kill or disable harmful bacteria through disinfection.

Students color-code a schematic of a cell and its cell membrane structures. Then they complete the "Build-a-Membrane" activity found at http://learn.genetics.utah.edu. This reinforces their understanding of the structure and function of animal cells, and shows them the importance of being able to construct a tangible model of something that is otherwise difficult to see.

Students learn about the different structures that comprise cell membranes, fulfilling part of the Research and Revise stages of the legacy cycle. They view online animations of cell membrane dynamics (links provided). Then they observe three teacher demonstrations that illustrate diffusion and osmosis concepts, as well as the effect of movement through a semi-permeable membrane using Lugol's solution.

In this unit, students look at the components of cells and their functions and discover the controversy behind stem cell research. The first lesson focuses on the difference between prokaryotic and eukaryotic cells. In the second lesson, students learn about the basics of cellular respiration. They also learn about the application of cellular respiration to engineering and bioremediation. The third lesson continues students' education on cells in the human body and how (and why) engineers are involved in the research of stem cell behavior.

In this lesson, students learn about the basics of cellular respiration. They also learn about the application of cellular respiration to engineering and bioremediation. And, students are introduced to the process of bioremediation and several examples of how bioremediation is used during the cleanup of environmental contaminants.

Schrauben lösen, Kabel neu verlegen: Messer, Gabel und Pudelmütze werden zum Input für den Computer. Ziel ist es, neue Benutzerschnittstellen für den Computer zu entwickeln, indem die TeilnehmerInnen einen Blick "unter die Motorhaube" einer USB-Tastatur werfen. So können Jugendliche im Alter von 13 - 17 Jahren erste Schritte im kreativen Umgang mit Elektronik machen und dabei viel Spaß haben.

Voraussetzungen sind lediglich die Freude am Experimentieren und die Neugier, technologische Grundlagen spielerisch zu erlernen.

This introductory class of computer skills is comprised of units that focus on basic computer hardware and the following applications: Word 2010, Excel 2010, PowerPoint 2010, Photo Gallery, and Audacity. Most units begin with YouTube overviews or 'how to' presentations followed by step by step guides to using aspects of the application and then have assessment exercises and conclude with a final project for evaluation.

Conditioning affects an animal's behaviour. Learn about classical and operant conditioning in this GCSE / K12 Ecology video from the Virtual School.

In this activity, students examine how to grow plants the most efficiently. They imagine that they are designing a biofuels production facility and need to know how to efficiently grow plants to use in this facility. As a means of solving this design problem, they plan a scientific experiment in which they investigate how a given variable (of their choice) affects plant growth. They then make predictions about the outcomes and record their observations after two weeks regarding the condition of the plants' stem, leaves and roots. They use these observations to guide their solution to the engineering design problem. The biological processes of photosynthesis and transpiration are briefly explained to help students make informed decisions about planning and interpreting their investigation and its results.

This activity is a field investigation of the biodiversity in a given area. The exercise will give students experience making scientific observations and creating a dichotomous key.

This activity is a field investigation where student gather data on organisms they find in or around a pond.

This activity combines field exercise soil collection with lab analysis of soil bulk density. Students develop a lab procedure to measure density and analyze data using Microsoft Excel computer software.

In this interactive demonstration students will make observations of diffusion of a semi permeable membrane and be able to compare these observations to the functions of a cell membrane.

In a multi-week experiment, student teams gather biogas data from the mini-anaerobic digesters that they build to break down different types of food waste with microbes. Using plastic soda bottles for the mini-anaerobic digesters and gas measurement devices, they compare methane gas production from decomposing hot dogs, diced vs. whole. They monitor and measure the gas production, then graph and analyze the collected data. Students learn how anaerobic digestion can be used to biorecycle waste (food, poop or yard waste) into valuable resources (nutrients, biogas, energy).

This is a lesson using Digital Age Skills in Middle School Biology.

This is a field investigation on diversity of life where students count the number of kinds organisms in two locations. Students report their results on posters and propose reasons why there might be difference in diversity between the locations.

This resource is about exploring how relationships are formed in an ecological system. Whether it be in a community, population, or even in a predator/prey situation. Energy flows through chains, webs, and pyramids in an ecological system. Understanding this energy flow helps us to see the diversity of the ecosystem and its inhabitants.

This activity is an in class lab where students will compare different acid solutions on seed germination and growth.
