Mixtures and Solutions
This unit covers introductory concepts of mixtures and solutions. Students think about how mixtures and solutions, and atoms and molecules can influence new technologies developed by engineers. The first lesson explores the fundamentals of atoms and their structure. The building blocks of matter (protons, electrons, neutrons) are covered in detail. The next lesson examines the properties of elements and the periodic table one method of organization for the elements. The concepts of physical and
Rolling Blackouts & Environmental Impact: What are our Electricity Options?
The goal is for the students to understand the environmental design considerations required when generating electricity. The electric power that we use every day at home and work is generated by a variety of power plants. Power plants are engineered to utilize the conversion of one form of energy to another. The main components of a power plant are an input source of energy that is used to turn large turbines, and a method to convert the turbine rotation into electricity. The input sources of en
The Seasons - Quiz
Pupils will revise seasonal changes in plants, animals, weather, heat and light.

Test your knowledge about cell differentiation, cell function and tissue culture.
"Communication System Design, Spring 2006"
" This course presents a top-down approach to communications system design. The course will cover communication theory, algorithms and implementation architectures for essential blocks in modern physical-layer communication systems (coders and decoders, filters, multi-tone modulation, synchronization sub-systems). The course is hands-on, with a project component serving as a vehicle for study of different communication techniques, architectures and implementations. This year, the project is focu
Using older and refurbished computers
This unit covers the basics of older and refurbished computers: what they are, the benefits and risks of using them, who should use them, and where to get them.
Using GLOBE Data to Analyze Land Cover
The purpose of the resource is to develop hypotheses about which environmental factors are most important to plants.
Photosynthesis and Respiration
Most people are aware that plants undergo photosynthesis, a process by which they convert sunlight and carbon dioxide in sugar and water. But not as many realize that plants also undergo respiration, which is the reverse of this process.
Total Ozone Emission
In this activity, students will analyze their nitrogen oxide emissions from all sources (including coal-fired power plants, natural gas combustion, gas-powered lawnmowers, etc.).
This lesson provides an introduction to the occurrence and possible risks of household chemical products. Topics include some basic chemistry (how elements combine to form compounds) and how chemicals are classified.
Drinking water treatment 2
This course deals with the design of drinking water treatment plants. We discuss theory and design exercises.
NASA KSNN What do plants need to grow?
By definition, a plant is a living thing that produces its own food through photosynthesis. This process uses carbon dioxide and water. Trapping light from the Sun, plants are able to change sunlight's energy into useable chemical energy. Not only is chemical energy produced, but oxygen is a by-product of photosynthesis. Plants are essential to the balance of life on Earth - and to life, as we know it, on other planets.
The Art of Teaching the Arts: Creating Rich Learning Environments
Arts teachers create a safe environment where students feel free to express their thoughts and feelings and take creative risks. In this session, participants meet an Acting I teacher who helps students let go of their inhibitions and an Acting II teacher who encourages students to take creative risks as they interpret monologues. In a dance class, a teacher asks students to work closely in pairs so they can study subtle aspects of movement technique. In a visual art department, the teachers wor
How to Create An In-Cell Bar Graph Using Open Office Calc.
This quick tutorial shows how to compare data using an in-cell bar graph in the Open Office Calc Program.
Junior Solar Sprint and Hydrogen Fuel Cell Car Competitions
The National Renewable Energy Laboratory hosts the U.S. Department of Energy's Junior Solar Sprint/Hydrogen Fuel Cell (JSS/HFC) Car Competitions. Middle School teams from all over the Colorado Region participate in this fun, educational and exciting event. Teams work together building solar and/or hydrogen fuel cell cars with guidance from a parent or teacher coach to compete in race and design categories. A "Spirit Award" is also presented to the team recognized for good sportsmanship. Building
Cell Division in Animals
This is a brief computer-animated video that describes differentiation in animals at the cellular level (cell division). Once the cells are differentiated they lose the ability to divide. As a result, one cannot grow a whole animal in a culture medium from a single cell. The growth of the whole animal in a single cell is only possible in the early stages of development - after the first one or two divisions. Other key words include: ectoderm, mesoderm, and endoderm.

Concentrate on Distracted Driving: A Challenge to MIT Students from U.S. Transportation Secretary Ra
From the MIT News Office:
Research has shown that talking on a phone while driving, even with a hands-free cell phone, causes as much of an impairment to driving ability as being drunk. And yet, says U.S. Secretary of Transportation
Ray LaHood, while the nation has successfully cracked down on drunk driving, when it com
How to Prune Perennials
Any lilac or bush is a good perennial plant to prune when they get
lanky. Learn from a gardener how to keep perennial plants looking even, and keep them green. The gardener demonstrates the process of trimming her rose plant.
Growing Lavender Plants
A gardener explains that growing lavender plants requires planting them in good compost or potting soil, putting them in a place with full, hot sun and trimming them back in the fall for a lush growth the following spring. Grow lavender plants in a garden, which repel insects and provide a lovely aroma. Lots of useful information and tips about about growing lavender plants in this clip.
