Students observe that plants need air, food, light, and water to survive.  In this plant biology lesson, students observe the growth and development of two plants, one is the control plant and the other is denied either air, water,...

Students examine how seeds germinate in a culture.  In this germination lesson students germinate seeds in gelatin and observe the growth of the plant.

High schoolers examine the environmental impact of global warming. In this environmental science lesson, students design and conduct an experiment about the effect of temperature on paramecia. They write a lab report about their experiment.

Young scholars explore an application of differentiation in this calculus lesson. They investigate the ideal dimensions for a soda can and, using the symbolic capacity of the Ti-89, investigate the dimensions of the can which has the...

Students explore botany by participating in a seed experiment. In this plant nutrition lesson, students define several science experiment vocabulary terms like observation, treatment, and replicate. Students utilize soaked seeds in a...

Students set up and conduct a scientific experiment to demonstrate data collection. For this scientific process lesson, students complete an activity with the specific objective of using a slingshot to fire a t-shirt into the crowd at a...

Middle schoolers develop procedures to explore the behavior of fish.  In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment. 

Students investigate what a controlled group is by creating an experiment.  In this plant growth lesson, students identify the different parts of a plant and discuss what is needed for a plant to be successfully grown....

Students investigate seed germination. In this instructional activity on scientific prediction, students conduct a scientific experiment using oat seeds.

Students discover soil and Earth movement by experimenting in class.  In this Earth Science lesson, students utilize a stream table, soil, graduated cylinder and water to create a re-enactment of a landslide.  Students simulate...

Learners estimate the pH based on the use of an unknown substance, determine whether an unknown substance is acid, base or neutral, and evaluate, by the pH determination, which of the unknowns is the strongest acid or base.

Learners practice using the scientific method. In this scientific processes lesson plan, students read and discuss the main parts of the scientific method. Learners plan how they would conduct an experiment using the scientific method.

Seventh graders hypothesize about the number of drops of liquid that can be placed on a penny before it spills over. They examine both the concept of devising a hypothesis and the idea of surface tension. They determine the difference...

Students conduct an experiment using leaf packs.  In this leaf lesson students complete an activity in groups and complete a handout. 

Students determine how speed is measured. In this physics lesson, students design an experiment to find out if the robot's drive wheel size affects its speed. They collect data and discuss results.

Students discuss what plants require in order to grow, identify plant parts and their functions and discuss a video about plants. They conduct a controlled experiment with bean seeds and then record and observe the bean plants.

Young scholars record data found at an assigned web site. In this data collection instructional activity, students access an assigned web site in order to complete a data chart about animals they see. They travel to different sections of...

Students examine different materials and design options that can affect the durability of a building.  In this investigative lesson students conduct several earthquake experiments. 

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...

During a macromolecule lab, young chemists perform multiple tests, including iodine starch tests, to determine if eight mystery foods contain lipids, sugars, or starches.

Which of the following can you survive without for the longest time: water, food, or a positive mental attitude? The answer may surprise you. Guide learners of all ages through games, activities, and discussions about surviving in the...

Help your class determine the types of pollutants coming from vehicle exhaust. Groups use an air quality monitor to determine the emissions from different vehicles, to gain knowledge about combustion energy, and to predict how the...

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....

Following detailed directions, teams collect the voltage and current outputs of a photovoltaic cell by adjusting the resistance. Using the collected data, they determine the highest power output. Implications for weather and a large...
