Sixth graders examine the factors that influence the stability of ecosystems. They construct a miniature ecosystem in a jar that includes plants, small fish, and snails, record the population changes over a period of four weeks, and...

Third graders view a demonstration of a teeter totter as a basis for assessing pre-knowledge of a lever. They create a KwL chart. Students work in small groups to conduct a variety of experiments. The first requires students to tie books...

High schoolers review the basic lab techniques by following lab procedures. They analyze data by using raw data gathered. Students comprehend the processes occurring inside the column. They use specific chemicals to help determine the...

Students work in small groups. They grab a handful of ice, and place the ice in an empty beaker of ice using a triple beam balance. Students heat up the beaker of ice over a hot plat until the ice has changed into water. They measure...

As an experiment is demonstrated for them, students write down their observations and brainstorm questions that can help them understand what they saw. After watching the experiment again—which demonstrates a soda can collapsing due to...

Students explore 1960's America. In this American history lesson, students read about and research 1960's political and entertainment figures, social activism, the Civil Rights Movement, and environmentalism as they complete writing and...

Learners determine the coefficient of friction for different surfaces. In this physics lesson plan, students identify the factors that affect friction. They collect data and write a formal lab report.

For any science class, learners can use this lab sheet to plan an experiment. It includes a space for the title, question, materials, setup, and procedure. If you want your class to complete this in typed form, you can provide the web...

Youngsters compare the heat-holding abilities of three different cans by insulating two with different materials and measuring the temperature change of hot water over a 20-minute period. 

Make pathogens and the body's defense systems come alive for young biologists in a hands-on activity. Investigators model the skin's protection against infection by observing and comparing changes in a punctured tomato and an intact...

Students, in groups, examine plants with different light levels. They are given plants from a tropical and desert region. They write a hypothesis at the beginning of the experiment.

Students apply Bloom's Taxonomy to reading selections. They prepare questions for each level of Bloom's Taxonomy and exchange them with other groups to answer. They answer another group's questions and report to one another.

Students brainstorm ideas for science fair projects. Students observe a PowerPoint presentation and explore the scientific method. In groups, they formulate a hypothesis. Using the internet, students research their topic and gather...

Students investigate why the sky is blue and the sunset is red. They are asked why do you think that we see the sky as blue? Students write a hypothesis on their "Blue Sky Lab Sheet". They explain why they think that the sky is blue...

In this honor chemistry I worksheet, students use all available resources to answer each question given. Students apply their knowledge of light, quantum theory of light, Bohr's model, photoelectric theory.

In this environmental science lesson, students write a short story about what it's like to help at an oyster garden. They formulate 2 hypotheses on the disappearance of oysters in Chesapeake Bay.

Sixth graders develop a reasonable hypothesis for a fictional science fair investigation. 'Raquel' is going to grow radishes and test for the best way to nourish them. They create a bar graph and write conclusions.

Students demonstrate how scientists use evidence to formulate hypotheses. They write an essay describing the Cretaceous and Paleocene time periods from the point of view of someone living in that time. In addition, they formulate...

Students conduct an experiment in which they react sodium bicarbonate with hydrochloric acid to determine the molar ration between the two reactants. Students must write correct formula and a balanced chemical equation and explain how...

Students test a hypothesis to see if there is a direct correlation between number of hours of TV viewing and academic grade. They collect and compile data to enter on a spreadsheet and create a word processing document supporting their...

Students investigate what happens to solids and liquids when they change from one form to another. The amount od space taken by frozen water begins the discussion and students are led to formulate their own hypothesis to research.

Pupils listen to oral story describing mystery artifact, work in groups to write descriptive report of artifact, and creatively form hypothesis based purely on misinterpretation. Students then explore and discuss difficulty of artifact...

Students will discuss the de Brogile Hypothesis and state the circumstances under which the wave nature of matter is observed. They will also calculate the wavelengths of matter waves.

Students examine troposphere graphs and mcompare their hypotheses with data collected by weather balloons launched from the NOAA ship, Ronald H. Brown. they write summaries about the physical properties of the troposphere.
