Students read examples of behaviors in various animals. They design an experimental question about the behavior. They explain if the question involves the proximate or ultimate level of causation.

Students investigate scientific methods by analyzing an article from the Natural Inquirer.  In this data analysis lesson, students read an article from the magazine and discuss at least 2 scientific methods that could be used to...

Students explore mimicry and crypsis, participate in hands-on predator-prey activity, and practice calculating averages and graph results in histogram.

Students apply the concepts from forensic science lessons to do a lab. They solve a mystery using experimentation and observation. They write a technically correct lab report.

In this variables worksheet, students are given seven experiments that they read and identify the independent variable, dependent variable, control group and standardizing variable.

Learners determine the density and thickness of a piece of aluminum foil. In this density and thickness of materials lesson plan, students experimentally find the density of a piece of aluminum foil and compare it to the theoretical...

Students examine the different properties that affect water quality.  In this pollution instructional activity students play a game, complete a hands on activity and computer lab. 

Seventh graders conduct an experiment.  In this bacteria lesson, 7th graders list living and nonliving things and brainstorm the characteristics they share.  Students are divided into two groups where they put samples of hand...

Student observe and quantify the respiration that occurs in yeast-molasses cultures. They complete an effective experiment in order to examine how to think critically about the results.

Students explore how wave energy that is generated and transferred in the ocean. They explore the aspects of a wave and how its energy affects the ecology of the seashore. Students engage in an activity that uses the nature of science...

Student use the scientific method to experiment with worms. In this characteristics of living things lesson, students predict and examine the reactions of worms to dry and wet soil. Students share their findings.

Tenth graders identify stars based on their line spectra. In this astronomy lesson, 10th graders analyze spectrograph and determine the elements present in the star. They explain the relationship between temperature and star classes.

Learners work in groups to conduct experiments the demonstrate the differences between static and kinetic friction. They consider how friction affects us in our everyday lives, determine the effects of weight on friction and complete a...
