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...

Everyone loves a lesson that involves throwing things around! To understand probability, your experimenters will predict how different cylinder-shaped objects will land when tossed. When the data is collected, they will calculate the...

How likely is it that the school cafeteria will serve chicken tomorrow? Discover the concept of probability with the roll of the dice. Pupils evaluate the liklihood of several statments about everyday life. Then, a mathematical...

Waste not, want not! Science scholars explore manure as an alternative energy source through reading and experimentation. Groups construct their own biofuel digesters and observe the process of methane production. The teacher's guide...

Grandma said to gargle with salt water for a sore throat. Was she right? In the last part of the seven-part unit, lab groups design an experiment to test a cells reaction to salt solutions. The pupils conduct their experiment to answer...

Dry ice is extremely cold — it is -109.3°F or -78.5°C. Scholars observe and explain the molecular motion associated with melting. Then they design their own experiments to speed up the melting process. Finally, a teacher presents a...

Caffeine affects your heart rate — or does it? Learners study experimental design while conducting their own experiment. They collect heart rate data after drinking a caffeinated beverage, create a box plot, and draw conclusions....

How can you complete a simulation when it is not practical to determine the probability of an event? Class members learn that in some situations, it is not feasible to find the probability of an event, but they can estimate it by running...

Do great gardeners really have green thumbs—or just really great soil? Environmental scholars discover what makes Earth's soil and soil quality so important through research and experimentation. Learners also develop an understanding of...

Young scientists learn what it takes for life on Earth to survive with this series of photosynthesis resources. Offering twelve different activities ranging from independent practice worksheets to in depth scientific...

Encourage your students' inner scientist by conducting experiments and recording their findings. This printable incorporates every part of the scientific method into an easy-to-read outline of experimental questions, research,...

Although graphing a linear inequality on the plane is but a few steps added onto the graphing of a linear equation, for many learners the logical leap is quite intimidating. This approachable PowerPoint presentation breaks graphing...

Why is lactase important? Biology scholars explore enzyme function in a structured inquiry lab. The activity tasks lab groups with observing how temperature and pH affect enzyme activity, as well as determining which milk products...

Protect skin from UV radiation! Groups design and conduct an experiment to test the effectiveness of UV safety products. The groups collect the data from the experiment and prepare a lab report. In the second day of the activity,...

Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...

Pairs use an online simulation to determine the epicenter and magnitude of an earthquake. Using real data about the earthquake's maximum S wave amplitudes, they then determine the magnitude. The resource provides a great career...

Never let them see you sweat ... unless you can't help it! Scholars design an experiment to determine the effects of stress on the body. They monitor sweat production under different conditions and relate the response to the function of...

How do the changing seasons affect the homes where we live? This question is at the forefront of engineering and design projects. Challenge your physical science class to step into the role of an architect to build a model home...

Design protection from high-speed particles. The STEM lesson plan highlights why astronauts need protection from space debris. Pupils use the design process to design, build, and test a spacesuit that will protect a balloon from a...

How do we learn the rules of society? How do beliefs and ideas affect these rules? Introduce your young sociologists to the factors that socialize individuals with a unit that uses observation and experimentation to analyze how factors...

The radical reactions of polymers seems abstract to many pupils, but this lesson turns them into a fun building game. Scholars use dice and building pieces to build polymers. Then, they determine the theoretical and experimental weight...

How does energy from the sun make plants grow? Scholars move step by step through the processes that promote plant propagation during a detailed lesson. The resource illustrates ADP production and hydrolysis, then allows learners to...
