Students experiment with water as a component of suspensions, solutions, and heat conduction contributing to the use of food and the health and wellness of human beings.

Students research biofilms and create brochures. They role play as advertising firm members assigned to educate the general public about biofilms. They create "wanted dead or alive" posters about harmful and helpful biofilms respectively.

Students drill and practice putting problems into vector form. They draw each problem before trying to solve them. Students draw arrows for any vector quantities to indicate magnitude and direction.

The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...

Now it becomes crystal clear why the unit is called Mixtures and Solutions. The fifth installment of a six-part unit explores mixtures and solutions. After viewing a demonstration on mixing pebbles with water, salt with water, and...

Elasticity and viscosity. Help your class understand the similarities and differences with an introduction to viscous fluids. After describing four types of fluid behaviors: shear thinning, shear thickening, Bringham plastic,...

Mix it up by using an intriguing resource that teaches young metallurgists that alloys are a metal mixture. They learn about the advantages of using alloys over pure metals and investigate titanium alloys as an example to finish the...

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...

Bend it, but don't break it. Groups investigate the strength of different materials. Using a procedure in the seventh segment of a 22-part series on aviation, pupils determine how far a rod will bend. They determine the strength-to-mass...

Groups use a marble to determine the viscosity of household fluids. The procedure calls for pupils to measure the amount of time it takes a marble to fall a specified distance in the fluids. Using unit conversions and algebra, the teams...

Future engineers test different alloys to determine the specific strength of each one. Based on the results, they make a recommendation to NASA on which alloy to use on engines for spacecraft.

Build a bridge to learning in a STEM-aligned unit about urban infrastructure. Young engineers explore the many aspects of civil planning and design in a five-day unit. Content includes the challenging aspects of balancing building with...

Take a trip to the Colombian rainforest through the sense of touch. Here, class members discover what's inside a mystery box: wood, cinnamon, Brazil nuts, a banana, and orange. Then, the class takes a trip outside for a tree rubbing...

How does climate change affect you? First in a three-part series, the activity focuses on how individuals living around the world are affected by climate change. Individuals take on the role of a given character and share their...

Students study water and its energy. For this water energy lesson, students discuss hydroelectricity and make models of water turbines.

Although not particularly educational, here is a creative group activity in which high school biologists will use their imaginations to create a new life form combining characteristics from existing life forms. Each group must come up...

Students are introduced to three types of energy transfer: conduction, convection, and radiation. They model the scientific process of fusion to become with the sun and how it produces energy.

"Humans have become a geologic agent comparable to erosion and [volcanic] eruptions ..." Paul J. Crutzen, a Nobel Prize-winning atmospheric chemist. Using Landsat imagery, scholars create a grid showing land use type, such as urban,...

Have the building blocks of the universe at your fingertips! Visually intriguing and animated, this interactive periodic table may also be the most informative chemistry tool available!

This is a must-have resource with everything you'll need for studying food safety with your pupils. From handwashing scorecards and cleaning kitchen surfaces to navigating the world of microbes and food-borne illnesses,...

Students demonstrate the movements and behaviors of creatures from different parts of the ocean.

Students differentiate physical and chemical change. In this chemistry lesson, students list examples of those changes. They apply what they learned in a Jeopardy style team game.

Students calculate the Balmer series. In this physics lesson, students observe hydrogen lamp spectra using spectrometers. They calculate wavelength and compare them with their theoretical calculations.

Students create a video of an object falling with a drag. In this physics lesson, students calculate drag coefficient using data from Logger Pro. They calculate velocity and acceleration of the object.
