How many of your pupils play an instrument? A musical science lesson will help all of them understand how string instruments work. Young scientists construct a string-and-pulley system to test frequency and pitch. The lesson...

Sugar isn't good for you, but it's great for yeast! Scholars design an experiment to investigate how variables affect the rate of sugar consumption in yeast. The last installment of a nine-part Life Science unit considers how scientists...

In this experiment worksheet, students give examples of independent, dependent, and controlled variables. This worksheet is a graphic organizer.

In this experimental design instructional activity, high schoolers are given a full comprehensive outline for designing an experiment. There are checklists included for each section of the experiment for students to use as a guide for...

Young scholars investigate the concept of a shadow. They design a tool to create shadows for an experiment. They make observations and record the size and shape of shadows. The instructional activity contains background information for...

Second graders perform a variety of experiments to observe, form conclusions, and make inferences.  For this experiment lesson, 2nd graders experiment based on the result of a pre-assessment. Students share what they have learned.

Students conduct an experiment to evaluate whether plants need soil to survive and grow. They plant two seeds, one with soil and one without, make predictions, and record and analyze the seed germination results on a worksheet.

Students are introduced to the concept of acids and bases and arouse curiosity about acids and bases in daily life. They are introduced to the measurement of soil pH. Pupils are introduced to the effect of soil pH on nutrient cycling...

Students investigate the effects of soil temperature, water availability, photo period and other variables of the growth of purple loosestrife. They observe the growing conditions of plants and alter them by adding water, isolating the...

Students state the controls and variables of the Newcombe spread experiment. They state a hypothesis for the Newcombe spread experiment. Students distinguish between the characteristics of a preexisting mutations and those of an...

Students watch a video show how to identify the independent variable, dependent variable and controls in an experiment; and design experiments that use controls to isolate a single independent variable and measure the resulting dependent...

Change one variable and try again. Teams build basic balsa gliders and collect data on their flight distances and times. Through collaboration, the team decides on two modifications to make to the basic design and collect data for the...

How much does your class know about psychology? What about empirical evidence? If they could use some time to learn the essentials of psychology, use a quick reference sheet to note what they know before the test, after the unit, and at...

Watch the excitement grow as learners experiment with homemade rockets. Pupils create their own rockets from a soda bottle and experiment with launch angles. They discover the launch angle has a significant effect on the distance the...

Help your class come up with a procedure for comparing the dissolving rates of colored candy coating in different temperatures of water. If you are placing importance on controlled variables with your class, make sure that they use equal...

How high did the ball go? Engineering teams build a working pneumatic system that launches a ball into the air. The teams vary the amount of pressure and determine the accompanying height of the ball. An extension of building a device to...

How does electricity travel through power lines? The simulation demonstrates the how changes in voltage and resistance are related to the distance between power polls and the thickness of the cable. Scholars control three variables in...

You might not be able to learn through osmosis, but you sure can observe it! Scholars observe and measure osmosis using chicken eggs. They control for multiple variables to determine which variables have an impact and how the impact...

Why do sprinters wear spiked shoes? Scholars explore various styles of shoes and how they handle forces when running. Scholars adjust variables including shoe type, horizontal force, surface type, and normal force to determine which...

Fire in the hole! Thrill your classes as they see what it's like to fire a cannon ball. Scholars practice aiming a cannon ball by altering first the firing angle, then the velocity, and finally both simultaneously. Can they discover the...

Knowing the temperature coefficient allows for the calculation of voltage output at any temperature. Groups conduct an experiment to determine the effects of temperature on the power output of a solar panel. The teams alter the...

Isn't building with blocks an activity for toddlers? The third lab of a five-part unit teaches young computer scientists how to create their own block instructions for programming. They use these blocks to create geometric figures, spell...

Japan is one of only a handful of countries that constructs buildings that are almost earthquake proof. The 13th lesson plan in the 20-part series challenges scholars to build structures to test against earthquakes. With limited...

In 1820, Hans Christian Orstead discovered the link between electricity and magnetism, which allows us to measure current and voltage. The simulation allows scholars to observe the inner workings of an ammeter and voltmeter as they...
