Students develop procedures to explore the behavior of fish.  In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment. 

Students use a thermometer to analyze soil temperature data to determine which soil sample is normal, and which one is permafrost. In this permafrost lesson plan, students participate in a hands on activity where they identify the active...

Ninth graders participate in classroom discussions, demonstrations and hands-on laboratory activities about pure substances and mixtures with a focus on common household materials. They investigate: What is a pure substance? What is a...

Learners study the process of evaporation.

Fifth graders build objects using various materials. They estimate the weight of the object using individual building pieces. Then they weigh the actual object and then tear it apart and weigh the pieces. They compare the two weights.

Students determine differences in concentrations. They have to state the problem they feel exists, consider possible solutions, and develop a plan to come up with for containers whose labels have fallen off. Students base this off the...

Students identify colors created by mixing primary colors and describe the process. They then design a book using the colors of a given season entitled "Colors of the Season".

Sixth graders experiment with mixtures. In this chemistry lesson, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.

Students take on the role of members of a concerned citizens group and discuss the transportation of spent-fuel rods from a local nuclear power plant and the safety issues that surround the power plant. Students work in groups to write...

Students describe how volcanoes are formed. They name the types of boundaries where volcanoes occur. They utilize models to illustrate the occurence of volcanoes and earthquakes along plate boundaries. They compare and constrast the...

Eighth graders are introduced to the various types of heat transfer methods. After taking a quiz, they pretend their hands are cold and offer suggestions on how to warm them up. They explain each type of heat transfer method and give...

In this mixtures activity, students fill in 7 blanks, determine if 4 statements are true or false, match 7 terms with the appropriate definitions, and solve 2 problems. These include topics such as homogeneous and heterogeneous mixtures,...

In this vector spaces worksheet, students identify the vector in a given set.  They explore addition and scalar multiplication in their vectors.  This two-page worksheet contains 13 problems.

Students study the design of snowflakes.  In this snow instructional activity, students discover the different shapes of a snowflake, and their similarities.  Students study snowflakes outside, then create their own with...

Students identify the different parts of a wave. In this physics lesson, students explain how animals communicate using sound waves. They discuss the effect of Navy's sonar on dolphins and whales.

Small groups of students perform paper chromatography to separate food dyes into their component colors. Students perform the experiment and collect, organize, and represent their data to form an explanation of their outcomes. Students...

Students study about chromatography, a process used to separate mixtures.

Learners build a Lego design and then work with a partner to reproduce that design. They guide the building of the reproduction by description only and then check their work.

Students observe that colored markers are a mixture of many different colors by performing a chromatography experiment. They make observations, record information, and make generalized inferences from their observations.

Eighth graders determine the density of a sinker by first finding the mass and then the volume using a graduated cylinder. Students must write the procedure they use to find the volume of the sinker then apply their data to follow-up...

Students group observed data, filtering from all their observations the similarities between burring threads. In the second part they make a comparison of a chosen attribute between the two threads.

Students use diffraction glasses to find similarities and differences between observed spectrum of fluorescent light and an incandescent light They work in groups of 4-6 for the experiment/activity part of this exercise.

Seventh graders distinguish between physical and chemical changes in both natural and technological settings. They identify the reactants and products for a given chemical reaction. they then write simple chemical equations given the...

Ninth graders generate and analyze data to determine which and how much of two polymers best absorb oils, formulate procedure to accurately determine how many times its own weight particular polymer can absorb, and develop understanding...
