If the methodology is skewed, the results will be skewed. That's the takeaway from an exercise designed to get class members thinking about research methods and statistics gathering. Instructors manipulate the testing environment to...

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

Students make and test hypotheses about atmospheric data collected aboard the NOAA ship Ronald H. Brown research cruise.

Students investigate the mystery of the "destructive force." They explore the concepts of natural phenomena. Students discuss the limited aspects of natural phenomena and the "whole truth" to generate new hypotheses that can be tested.

Students examine samples of common dust from their homes and school under a microscope. Students describe their samples including the location from where they were collected, and compare their samples to make hypotheses about their...

Students define an exploration question or hypothesis and design a scientific study to answer it. They conduct the experiment.

Students research a complex question. They work together to form hypothesis and research the question and analyze the data. They present their "decision" to the class based on their work.

Students investigate the concept of an aquifer and use a 2 liter bottle and other materials to conduct a simple lab experiment or demonstration. They calculate the volume of water that can be stored in the aquifer. The lab is used to...

In this statistics learning exercise, students analyze the data provided in order to determine the null hypothesis, an alternate hypothesis, and the significant difference between the groups.  The one page learning exercise contains...

Students demonstrate how to create and test a hypothesis. They design an experiment and set up a variable, experimental group and control group.

Learners test the hypotheses using p values. In this statistics instructional activity, students define and examine conditional probability. They test each statement for a true statement or a false statement, based on the sample size.

Second graders pop popcorn as a way to experience the scientific process. They form a hypothesis, carry out an experiment and explain their findings.

Pupils create a biosphere using the computer program SImEarth. They work in small groups to create "Daisyworld" in which they model aspects of the Gaia hypothesis. They form a question to answer and choose variables to investigate in...

Young scholars perform classroom experiments to observe adhesion. They perform a second experiment using sand, salt, water, and a heat lamp to observe the principle of capillary action. They also experiment with adhesion in plants.

Students examine the Michigan state quarter and discuss the effects glaciers have on land formation. They perform an investigate using ice cubes and sand to show how glaciers have carved the land.

Young scholars investigate a scientific phenomena. For this scientific investigation lesson plan, students hypothesize why water rises around a lit candle sitting in a pie tin of water as it is covered. They reflect on questions raised...

In this scientific investigation worksheet, students answer 16 questions about conducting a scientific experiment on marble's and their velocity at different ramp heights. Students write a scientific question and then go through the...

In this experimental design worksheet, students describe the different science skills required when designing an experiment. Then students create a flipbook with the information. This worksheet has 9 short answer questions.

High schoolers experiment and compare results of two populations. In this men and women populations lesson plan, students examine the difference in hand span for men and women.  High schoolers calculate a norm based on their...

Students explore matter. In this physical science lesson, students role play the 3 states of matter forming "liquid" molecules and "solid" molecules with teammates. Students perform an experiment in which the result illustrates that two...

In this digestion and nutrition lesson, 3rd graders test foods to find their vitamin content. Students test for starch and fats then compare their findings on charts and oral reports. The lesson concludes with a teacher directed...

In this problem solving worksheet, students are given a series of events that occur in the Chesapeake Bay related to the rockfish. Students provide a solution to saving endangered fish and they use information/data to hypothesize why...

Students examine how scientists are at odds on whether or not dinosaurs were warm or cold blooded.  In this dinosaurs lesson students divide into groups and research the evidence that supports each side. 

Students investigate clams. In this clam life lesson, students conduct an experiment where they dissect clams. Students compare anatomies of humans and clams.
