Learners investigate simple machines. In this simple machines lesson, students identify the six simple machines from an object or drawing. Learners also use various objects to identify the simple machines found in a compound machine.

Students explore magnetism. In this magnet instructional activity, students assemble a magnet pendulum. Students observe the pendulum noting the location of the magnetic poles as they construct the pendulum so that the free-swinging...

Students examine why electricity is distributed at high voltage and the functions of transformers.  In this electromagnetism lesson plan students study at what frequency electricity is distributed. 

Students consider how the first supercasino in Britain will impact the nation. In this current events lesson, students visit the noted Web sites to gather information about the casino and the positive and negative effects of gambling.

Students consider the implications of playing violent video games. In this current issues lesson, students visit selected websites to research virtual violence and video game censorship.

In this spelling list worksheet, learners practice spelling words that are sight words, final blend -mp, and vocabulary. Students practice spelling 16 words total.

In this famous leaders worksheet, students read a passage about Aung San Suu Kyi and then complete a variety of in-class and homework activities to support comprehension, including partner interviews, spelling, cloze, synonym...

In this properties of air worksheet, students experiment with a jar, a plastic bag and rubber bands to simulate that air takes up space and exerts pressure. They make observations and answer questions about their experiment.

Students investigate the relationships between weights, and construct a balanced first class lever. They formulate a general equation for the relationship explored in the experiment and perform calculations.

Students explore genes and the way we age. They assemble a worm collection device called a Baermann Funnel. Students collect Caenorhabditis elegans or other active nematodes from local soil samples. They observe the appearance and...

Students investigate how a spinning paper tube generates lift as it travels forward.

Students determine the concentration of acetic acid when the concentration of the base with which is titrated is known. They investigate how to weigh a sample using the balance, measure volumes using graduated cylinder, explore the...

Young scholars participate in a lab activity in which they examine the permeability of different soils. They examine the soil's composition and make predictions about the permeability of the soils. They share their observations to the...

Students conduct an experiment to determine the effects of soil color on its day and night time temperatures. In small groups, they prepare dishes of black soil, brown peat moss, and white sand. They record the temperature changes when a...

Learners conclude that magnets and magnetic fields can produce electricity. Students also understand how a small motor works and how gears work. Learners describe how energy can transform along a pathway.

Students form their own hypothesis about the relationships between force, mass, and acceleration for their dynamics cart system. They collect data and express it in a graphical format to visualize the relationships.

Students determine the number of calories in various products, and the amount of energy created when objects burn.

Third graders work together to lift and pass each other through a tire. They simulate time travel and decide on an object they would take with them through the time portal. They reflect on their experiences and consider the importance of...

Learners examine the part that transpiration plays in the hydrologic cycle. They observe how plants play a role in maintaining a stable environment.

Students experiment to determine the effect of the frequency of collisions between atoms or ions of the reactants. They investigate the rate at which aluminum replaces hydrogen from a solution of hydrochloric acid.

Learners explore six simple machines and locate them operating in a compound machine. The simple machines are identified at a variety of stations set up in the classroom and continued by identifying the machines in their homes.

High schoolers demonstrate that motors work on two different voltages. They connect a single-phase AC motor to run on different voltages.

Students participate in an experiment that shows them how to use their senses to find their way "home." This experiment is based on the video that shows how salmon find their way to their home stream.

Students work together to examine inclined planes. They create a plan to raise rocks to build pyramids. They discover the changes that occur when the angle is increased or decreased.
