What is the difference between accept and except? Affect and effect? Brilliantly advise your class with the advice in these slides. Definitions of commonly misused words from A-Z help clarify meaning and usage.

Course identification information is included in the upper left corner as well as within the title of this worksheet. If you overlook or remove that information, you are left with a tremendous college biology assignment. There are only...

Biology aces answer four questions about genetic recombination and nine questions about pedigrees. This instructional activity is very focused on these two topics. Most of the pedigree questions relate to the genetic disorders,...

Biodiversity is essential for every habitat, but many species are at risk due to pollution and other factors. Explore several different species native to Illinois in a gallery walk with posters that learners have created after research...

Although originally designed for young film makers who wanted to enter their videos in a contest, the step-by-step instructions included here would serve as a guide for any video project. Classes with no access to video editing software...

Tired of waiting for hot water? Groups of three determine the efficiency of an electric water-heating device. They calculate the amount of energy it takes to heat the water and the theoretical amount of energy required to heat the water....

Some things are hard to resist. Small collaborative groups build circuits and calculate the voltage using Ohm's Law. Budding engineers explore the connection between the voltage across different resistors and linear...

How high did the ball go? Engineering teams build a working pneumatic system that launches a ball into the air. The teams vary the amount of pressure and determine the accompanying height of the ball. An extension of building a device to...

With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...

Whether or not Galileo actually dropped balls from the Leaning Tower of Pisa, this demonstration will solidly demonstrate that objects are accelerated at the same rate, regardless of mass. You will, however, need a vacuum pump and a few...

Taking on the roles of a fiery Boston patriot, a Philadelphia merchant's wife, and a prominent abolitionist, your young historians will consider the reactions of these early Americans to the creation of the Declaration of...

Step into the role of a zoo director with several activities about animal training and running a zoo. Kids calculate the amount of food each animal needs, design a habitat for penguins, decide how to breed bottlenose dolphins, and train...

Move beyond buttons when designing user interfaces. In the fourth installment of a 21-part unit, young computer scientists learn to apply design mode, which gives users options for colors, fonts, etc. They learn to incorporate these...

Scholars continue their study of event-driven programming by creating a multi-screen app in the fifth instructional activity of the series. They incorporate previously learned elements and events in the mini-project.

Pupils learn to apply strings in computer science. They master two new user interface elements and also use string type data to represent ASCII characters. Finally, individuals create an app for Mad Libs in the eighth lesson of the series.

How does a computer recognize voice commands? Scholars learn about digital assistants and natural language processing (NLP) algorithms in the ninth lesson of the series. They begin building a simple digital assistant and work on this...

Tiny particles can provide big learning opportunities! Middle school scientists explore the world of nanoparticles through reading, discussion, and experiment. Collaborative groups first apply nanotechnology to determine water...

You arrive at school only to be told you have no place there. Scholars research the Supreme Court cases Mendez v. Westminster and Delgado v. Bastrop ISD, both dealing with school segregation. Two short video clips as well as small group...

Scholars collect data from heating sand and water before forming testable hypotheses about why sand heats up faster. Afterward, they develop and run experiments to test their hypotheses.

Students develop classification scheme that meets the established rules of the Linnaean system. They write one page essay on classification choices.

Students become familiar with real-world gathering of chemical data. The experience how the science is done: the nature of analysis, data collection, interpretation, and presentation. They study a nearby body of water for their experiment.

Learners discover that mining for nonrenewable natural resources has a dramatic effect on our environment. They gain an understanding of the processes involved in harvesting a natural resource and the impact it has on the earth.

Students study the water quality of a stream in their area, by measuring the temperature, pH, alkalinity and conductivity. They integrate biology with earth science when using the microscope to study the living organisms in the water.

Students observe and classify objects that float or sink.
