Students research the conditions in which molds thrive. They apply the scientific method to develop a hypothesis, conduct research and test results.

Students gather data about bird populations. They study bird migratory patterns using the methods that researchers use. They write an essay explaining the differences between the four types of population movements.

Second graders define condensation and evaporation. They identify and describe the steps in the water cycle. They ask questions to end the lesson.

Students explore the factors that affect how long coffee stays hot. They develop a question and a testable hypothesis for one factor such as initial temperature or size of opening of the container. Then they design and conduct an...

High schoolers design and conduct a scientific experiment to test which of four antacids would be most effective for neutralizing acids. They rank the antacids in order from most effective to least effective and explain how they...

Students investigate and compare the bouncing ability of the materials from which four different balls are made. They determine which material performs the best for use as a basketball. After collecting data in a small group they...

Young scholars examine pollen and fibers taken from a garment. They analyze pollen from new hybrids and compare it to the samples from the garment then make individual conclusions concerning the specific historical authenticity of the...

High schoolers are given three unknown samples and must perform two chemical tests in order to determine if the samples contains protein and/or starch. Students work with corrosive or toxic reagents.

Middle schoolers are assigned to groups, and determine each member's role in the group. They will design an experiment to determine a way to produce the three primary and five secondary colors. Students discuss color and mood. They...

Students record data found at an assigned web site. In this data collection lesson, students access an assigned web site in order to complete a data chart about animals they see. They travel to different sections of the web site to find...

Seventh graders demonstrate scientific inquiry to design and perform an experiment involving Grow Creatures. They participate in a class discussion, and in small groups design an experiment that determines how to change the materials to...

Students apply an interactive smog visualization application, Smog City to see how ozone levels are related to population levels and emissions. They study associated vocabulary and complete a worksheet.

Students evaluate the notion of aging by reviewing some of the studies that occurred on John Glenn's space shuttle mission.

Learners experiment with enzymes as key components of chemical reactions in all living things through this series of lessons.

Third graders complete a diagram of the revolution of the earth around the sun and write a one paragraph explanation of the factors that cause seasons.

Fourth graders explore the earth's revolution around the sun and the changes in weather that follow this motion.

Students determine the changes in different types of water in a sealed container over time. They investigate how to measure dissolved oxygen, temperature, and carbon dioxide with calculator or computer probe-ware. Students determine the...

Students use FoilSim interactive software to become familiar with the way in which the flow of air across or around an airfoil affects its ability to create lift.

Fifth graders test the shelters that were built in a prior activity. They determine the level of durability and water resistance of these shelters through a scientific investigation.

students study bird migratory patterns and the methods that researchers use to study them. Students are introduced to the concepts of the study of bird movements.The skill of scientific questioning is used to find results.

Students design an experiment to analyze the timbre of different instruments. In this physics lesson, students analyze the missing quality in sound. They discuss their results in class.

Students design, build and test model race cars made from simple materials (lifesaver-shaped candies, plastic drinking straws, Popsicle sticks, index cards, tape) as a way to explore independent, dependent and control variables. They...

This site from Glencoe Publishing not only explains hypothesis but also tells how to design an experiment to test your hypothesis. Includes the difficult task of "Separating and controlling variables."
