Lead your biology class on a cell-sized adventure! Emerging scientists construct models of prokaryotes, then design an experiment to properly grow a bacterial culture. They conclude the activity by viewing the culture under a microscope....

Young chemists grow ionic crystals, metallic crystals, and supersaturated crystals in three different lab experiments. Observing these under a microscope allows pupils to compare the various structures. 

Using simple materials, an informative lesson demonstrates the Law of Conservation of Matter and explains how to balance chemical equations. Young chemists perform experiments, analyze reactions, and balance chemical equations...

Young chemists perform an experiment to determine if a compound is iron (II) chloride or iron (III) chloride. Then they determine the formula, balance the equation, and answer analysis questions. 

If your pupils think a catalyst is a list of their cats, then this might be the lesson for you! Young chemists study the effect of temperature, catalysts, concentration, and particle size on reaction rates during four different...

Students perform experiments designed to grow plants and bacteria in a controlled environment.  In this ecosystems lesson students investigate varying conditions for growing plants and bacteria. 

Fascinate young life scientists by showing them how their brain learns. By using prism goggles while attempting to toss bean bags at a target, lab partners change their outlook on the world around them, producing amusing results....

Discover the connection between electric current and magnets. Scholars create electromagnets by passing a magnet through a coil. They experiment with different materials to determine the variables that affect the strength of the current.

Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome. 

One of the factors that automotive engineers must consider is wind drag. The less wind drag, the more efficient the car will be. They perform many tests in wind tunnels, then refine their designs and test again. Using simple materials,...

How do the laws of motion work in space? Learners explore Newton's laws of motion in different experiments as part of the Christa's Lost Lessons series. They rotate around the room in three stations to experience each law in action using...

With the use of a model rocket kit, aspiring aerospace engineers work cooperatively to construct and launch a rocket. A preparatory reading assignment is included, covering Newton's laws of motion and information about the first...

Up, up, and away! Take your classes on a physics adventure. Learners explore the concepts important for flight. They experiment with the Bernoulli Principle while learning the forces that act on airplanes in flight.

Youngsters examine resource maps to find out which states are using solar and wind power and discuss as a class various other renewable energy sources. They use a provided data table to record pros and cons to each technology, build and...

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

Dive into an exploration of the water cycle cycle with this simple earth science lesson. After first discussing where rain comes from, young scientists define the terms condensation, evaporation, transpiration,...

Pupils often wonder how we know the distance to various stars. Starting with a thought experiment and progressing to a physical experiment, they determine the brightness and distance to various stars. The evaluation requires...

Historians believe the first vertical water wheel was invented in Rome during the Augustan Age. The sixth lesson in the series of 10 has scholars experiment with designing their own water wheels. Through testing various pastas and...

Can you feel that? Can you smell that? Since pupils can't ask worms about their sense of smell and touch, they design and complete an experiment to answer these questions. Individuals expose nematodes to different stimuli using their...

Test the levels of vitamin C in different juices. After a lesson on the importance of vitamin C in our diets, learners use titration to determine the vitamin C content in juice. They use their experience with the titration to study the...

How much do you really know about our planet? Middle schoolers build up their prior knowledge about Earth, its placement in the solar system, its composition, and important geological vocabulary with an introductory earth science lesson.

How do oceanographers make maps under water? Junior explorers discover the technologies and processes involved in creating bathymetric maps in part three of a five-part series designed for fifth- and sixth-grade pupils. The lesson...

Fifth graders research and complete a graphic organizer about the principles of flight. In this aviation lesson, 5th graders experiment to understand the work of Daniel Bernouli and his discoveries about air pressure. Students create...

Students discuss the effects of earthquakes. In this earth science lesson, students create earthquake models and earthquake-proof buildings. They construct their own seismograph.
