Students explain the importance of having a control when setting up an experiment.

Ninth graders examine how a scientific investigation is performed. They read and discuss examples of various scientific experiments, design an experiment involving fast growing plants, and create graphs and charts to present their...

Fifth graders compare and identify variables that affect the rate of a chemical change using Alka-Seltzer, water, ice, and hot water. They time how long each variable takes to pop the canister into the air, and record the results on a...

Students investigate plant tropisms using the scientific method. In this life science instructional activity, students learn about tropisms and test the response of corn seedlings to gravity. Response questions, extensions, and an...

Learners will work in groups to design and conduct an experiment to identify amino acids found in an unknown solution. This lesson is taught in three sections: (1) Introduction to chromatography (2) Experimental design session (3)...

Students research the International System (SI) of units of measurements. They make measurements using the metric system. They study key concepts used in building and use of sensors, how sensors work and their role in measuring...

Eighth graders investigate the effect of temperature on the volume of a gas in a closed container. They measure the height of the water in their beaker/container, conduct their experiment, and create a graph to illustrate their data.

In this life characteristics worksheet, students answer 16 questions about living things, Redi's experiment, basic needs, growth and development.

Students use the scientific method to investigate the role of temperature in microbial growth. In this food preservation lesson, students set up an experiment with fruit in room temperature and in a refrigerator. They record the...

Students investigate the properties of matter. In this properties of matter lesson, students observe containers of different metals and discuss their properties including density. Students find the density of an unknown metal and of...

Learners discuss physical places in which had good or bad acoustics. After reading an article, they discover the relationship between the physics of sound and concert hall acoustics. They calculate the speed of sound and compare their...

Students experiment with carrying eggs to simulate a mother crocodile's gentle grip as she carries her eggs/young. They compare different modern tools to the jaws of a crocodile.

Sixth graders conduct experiments with yeast to study characteristics of microorganisms. They, working is small groups, change the variables in the experiments and note the results which they later discuss as a class.

Students investigate the acidity and alkalinity of common household products in an experiment. They use red cabbage juice and litmus paper to show the difference between strong acids and bases as they work with vinegar, dish washing...

Students investigate how natural selection influences evolution. They complete a hands-on lab simulation of natural selection, and replicate a real experiment and examine the interplay between selection factors in a population of guppies.

In this scientific method learning exercise, students complete a crossword puzzle given 21 clues about the steps of the scientific method. Topics include observations, hypotheses, variables, inferences, results and conclusions.

In this minerals and experimental design worksheet, students answer questions about variables in experiments, identification of minerals, mining and properties of minerals.

Fifth graders use information from their text to read and discuss pulleys and levers. They examine a top sketch of the arrangement of a fixed pulley. Working in groups, 5th graders perform experiments to test the effect of using a pulley...

  Students build boats out of clay to test the buoyancy of the boat in water.  Students break into pairs and construct their boat to specific guide lines, then experiment with their boat in the water.   

In this lab design and lab skills worksheet, learners answer questions about experimental design including finding variables, determining controls, and graphing data. They answer questions about microscopy and label the parts of a...

Young scholars examine the health effects of hazardous waste on people. They work together to complete an experiment in which worms are exposed to chemicals. They discuss the results of the test.

Students observe mold growth on bread. For this mold growth lesson, students place bread in various locations and in various conditions to investigate how location, moisture, temperature, and other variable impact the growth of mold on...

A set of questions on weathering and erosion are found in this resource. Some of them can be used as discussion topics or lecture guides. There are also suggested activities such as the examination of topographic quadrangles and the...

In this speed formula and scientific method worksheet, students read over descriptions of the formula an method. Students then respond to 12 matching, problem solving and short answer questions.
