Explore genetically modified foods through various experiments. In this biology lesson, high schoolers discuss the safety issues related to GMF's. They conduct a PCR analysis to identify the presence of genetic modification.

In this petroleum products activity, students are given the components of crude oil and they graph the various products found in a 50 gallon barrel. Students complete an activity to determine if they have collected cards that represent...

Students know that participation in sports requires energy. They comprehend that we get energy form the foods that we eat and the air thta we breathe. Converting food and air into usable energy is defined as celluar respiration. Students...

You never know what you will find next in the deep sea ecosystem. So far, scientists have found items that work as anti-tumor agents, anti-inflammatory agents, agents that stop uncontrolled cell division, and much more. The lesson begins...

What goes into a museum display? A secondary-level STEM project prompts groups to design a museum display for the Tech Museum of Innovation. They create an analogous, interactive model illustrating a science concept to complete the...

Can you find a match? Scholars review the 12 principles of green chemistry by playing a matching game. The second lesson of the series reinforces the principles from the first lesson. Individuals play the matching game and also complete...

Is it possible to create an environmentally friendly shampoo? Learners accept this challenge in the fifth instructional activity in a green chemistry series of 24. The analysis of their shampoo ingredients must address pH, exothermic...

Water, water, everywhere, but not a drop to drink—until we clean it, of course! Scholars design a filtration device that removes pollutants from water. The goal is to have the water come out as clean as possible from the device. How...

Young scholars explain the four stroke process in internal combustion engines. For this physics lesson, students role play this process and present their reenactment in class. They draw and label the diagram of an internal combustion...

Students examine the factors the affect water quality, and allow for animals and plants to live. They look at how engineers apply water quality information when making stream modifications in order to ensure drinking water quality. They...

Students study the basic elements of the Earth's crust: rocks, soils and minerals. They categorize rocks, soils and minerals and how they are literally the foundation for our civilization. They also explore how engineers use rock soils...

Nano-nano! Nanotechnology can seem like it's from another planet! After learning about this tiny technology, collaborative groups experiment with how smaller particles affect chemical reactions. They do this by immersing a whole and a...

Students engage in three short, hands-on, in-class demos which expand students' understand of energy. First, using peanuts and heat, students see how the human body burns food to make energy. Then, they create paper snake mobiles to...

Introducing ... the aerogel. The first of a two-installment series teaches young engineers about the properties and uses of aerogels. A PowerPoint presentation provides information about this unique material to help solidify the concept.

Students make a class list of household products and discuss how many of these products are made through chemistry. They guess the ingredients in the products and imagine how toothpaste might be made. They make toothpaste.

The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The lesson covers the topics related to...

Wouldn't it be great if you could produce your own food? Scholars learn about the processes of photosynthesis and cellular respiration in plants. They consider how to use photosynthesis as a model of an efficient system and how to apply...

Learners design an investigation using yeast. In this environmental engineering instructional activity, students design an investigation to determine how environmental factors affect the growth of yeast. They will collect quantitative...

How do one's habits and lifestyle choices affect the environment? Through a short online survey, learners will calculate their own carbon footprints then determine how to reduce their impact on the environment through simple steps, such...

Students create piston systems and explore the conversion of linear to rotary motion that propels a car. In this motion lesson, students build and test a model piston/crankshift system and discover why there is a maximum limit to how...

In this crude oil worksheet, students read about the fractions of crude oil and their demand. They answer questions about the data given.

Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply. 

What constitutes a good soap bubble? In the second installment of a nine-part series, scholars apply their understanding of surface tension to soap bubbles. They experiment to determine the best solutions to use for the...

Back to the basics (of surface tension). The first installment of a nine-part series teaches young scholars about the basics of surface tension and how it relates to water droplets. They also learn how this concept allows for the...
