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.

Young scholars explore electromagnetism, simple machines and the design process. They use the concepts of electromagnetism to design and build a device that uses an electromagnet, a pulley and a lever using the provided Engineering...

Students explain the principles of experimental design and reinforce the steps of the scientific method. Each group of students create a "slush" type mixture to store a chicken liver.

Students gain an understanding of the real world applications of the scientific method. They design their own experiments to prove or disprove the existence of other modern legends, and they design and carry out an experiment to test a...

Students design and construct a listening device that will allow them to listen to the sound generated by specific object inside a box.

After reading an interesting account of how the X-1 aircraft was designed, built, and utilized, young engineers try their hand at constructing a paper glider version of the airplane. They cut out the plane out of a nicely designed...

Through two investigations, life science learners determine whether or not yeast is alive. They perform tests for metabolism by providing sugar and observing if gas is produced as a byproduct. They incubate some of the sample for at...

Learners design a pumping device that will effectively pump fluid through a model "cardiovascular system." They explore the effects of too much and too little pressure on a circulatory system.

Look around and explore. Little ones use their five senses with some day-to-day activities designed to guide observation and apply STEM strategies. Young scientists learn through comparing/contrasting and...

Junior geologists work through three mini-lessons that familiarize them with the formation and location of fossil fuels. Part one involves reading about petroleum and where it comes from via a thorough set of handouts. A lab activity...

How are raptors and airplanes alike? Combine science and language arts in this fun and interactive project. Young scientists research the animal in order to design their own aircraft, and compete in a contest for farthest, fastest, and...

Dare your class to drive dissolved carbon dioxide out of carbonated liquid at different temperatures to discover if there is a difference in rate. To make this experiment more sound, have explorers use equally measured amounts of soda...

Not all liquids are the same. Investigate the viscosity of different fluids with a series of activities designed for eighth grade science. As learners move through learning centers with different experiment setups, they determine...

Students practice problem solving skills and experimental design. They build a vehicle that can traverse "glacial" ice capable of carrying a specific load and glide smoothly, creating as little effort as possible for the skier pulling...

Learners will work in groups to design and conduct an experiment to identify amino acids found in an unknown solution. This lesson is taught in three sections: (1) Introduction to chromatography (2) Experimental design session (3)...

Students design an experiment. In this bees instructional activity, students research pollination and work collaboratively to discover how bees aid in pollination.  Students use tomato plants and create experimental designs....

Students develop a test tube model of an oil spill in order to experiment with conditions needed for bioremediation. They apply the principals of experimental design by analyzing a research article on the EXXON Valdez bioremediation...

Students design an experiment to change the motion of a rolling marble. In this designing an experiment lesson plan, students form a research question, they develop a hypothesis and they design an experiment using a graphic organizer to...

Pupils examine the concepts of forces and motion. They work together to design protective devices for their egg rovers as they are dropped from a specific height. They record their observations and discuss.

Use simple machines to escape from a tree house. Pupils learn about simple machines and how they are useful in everyday life in a STEM lesson. Groups then design a device to rescue a friend stuck in a tree house.

Sixth graders design experiments to compare the amount of bacteria in river water to the amount in purified tap water. They explore how water purification removes bacteria and pollution from the water. Students examine the steps of the...

Young scientists discuss the results of carelessness during experimentation and the temptation to misrepresent findings. These activities are intended to develop the ability to identify scientific error, misconduct, and fraud. Use this...

First in a two-part instructional activity on the greenhouse effect, this instructional activity involves a classroom demonstration of the phenomenon, and a lab group experiment with color and absorption. Although there are easier ways...

Students explain chemical, cultural and biological weed control methods. They design and conduct an experiment to simulate a weed control method and explore various ways to prevent weed dispersal.
