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...

Objects contain pigments that selectively absorb a wavelength of light, and our eyes only observe a very small range of these wavelengths. Scholars apply these two facts to three different activities. They identify the pigment in an...

What's the best way to collect all that trash? A culminating activity has scholars use the knowledge and skills from the unit to design a solution to the plastic trash island problem. They use 3-D pens or a 3-D printer to build models of...

THINKGREEN has a computer printer cartridge collection program. After reading the story of how Assumption Secondary School in Burlington, Ontario started participating in the THINKGREEN recycling program, pupils work in groups of...

Elementary ecologists pretend to be migratory hummingbirds. They fly between wintering and nesting grounds, trying to reach a habitat haven. In a musical-chair fashion, some birds will miss out, and are removed from the game. To further...

Reach out and grab something. Given the task of picking up objects at least two feet away, pupils design and build a grabber. The last activity in a series of five challenges requires learners to use information about fulcrums and levers.

Who says playing around in class is a bad idea? Precocious physicists engage in building mechanisms that include cams, gears, pulleys, and levers using an interactive lesson. After completing toy tutorials about each topic, users build a...

Students create, organize and advertise a recycling center in their classroom. Students brainstorm different items that could be recycled, including cell phones and printer cartridges. Various recycling stations are set up in the...

High school learners read and discuss an article about genetic ancestry and genetic ancestry testing. They complete a paper and pencil activity that mimics the function of a DNA microarray and consider the ethics of genetic testing in...

Photocopy single-color images onto acetate transparencies and either demonstrate or have your class experience the combination of colors to produce images. Children will learn that cyan, magenta, yellow, and black combine to make all of...

By overlapping combs and window screening and by looking at a printed set of consecutively larger circles, learners observe Moire patterns, which provide a visual of what happens during wave interference. 

Youngsters test magnetic strength by measuring the mass of paper clips that they "hook" with a magnet. Your first and second graders should love the hands-on activities associated with this plan. The reproducible materials are quite good...

Students investigate issues of degradation and weathering of polymeric materials during their useful life. They evaluate photodegradable plastics and their viability as an environmental solution for litter and investigate the qualitative...

Students grow E. coli strain HB101, which contains the plasmid pUCD607 with the bioluminescence (Lux+) gene. The plasmid containing the Lux+ gene is isolated from the E. coli, then characterized by restriction analysis.

Students explore DNA restriction mapping. They cut pieces of paper into lengths representing those produced when specific enzymes are used to cut a strand of DNA.

Students extract DNA from their own hair roots. They run an electrophoresis gel to examine patterns of their DNA along with standard DNA. The experiment is based on a crime scene scenario.

Students simulate life in space aboard the space shuttle. In this space exploration lesson, students work in small groups to model life aboard the space shuttle. Each student is given a job, conducts Internet research on space, and...

High schoolers will identify the factors that contribute to erosion and weathering. They will start by differentiating between chemical and mechanical weathering. They then apply what they learned by playing the online jeopardy game. Key...

Genetics learners read an article and watch a video about personalized medicine and the hope it holds for treating patients more specifically than doctors currently are able to. They research, design, and produce a brochure about the...

Here is a 20-box bingo card to use when exploring ways that humans impact the environment. Various environmentally aware activities are listed in the boxes, and learners circulate the room to find someone who practices the different...

Around 93 percent of the reefs on Australia's Great Barrier Reef have been bleached, and almost one quarter of them are now dead. Scholars research the sea temperatures, especially around the areas with coral reefs, to make connections...

The 20th activity in a 21-part series connects the wind data and expectations of a turbine to whether such devices should be built in your area. Scholars begin with estimating the wind potential at school by using long-term climate...

The final instructional activity in the 21-part series on climate change focuses on energy solutions to the consumption problem. Using data specific to their school, pupils make recommendations, follow up on actions, and carefully...
