Students investigate photosynthesis in water plants. In this photosynthesis lesson plan, students use the elodea plant and observe gas bubbles released to determine the rate of photosynthesis. They vary the light intensity and the amount...

Learners investigate refraction and reflection of light. In this light lesson, students perform 3 activities to observe light interacting with matter by using a flashlight. They explore refraction using a glass of water and reflection...

Students construct two dimensional models to illustrate squared numbers. In this geometry instructional activity, students use graph paper and an x/y axis to build squares exponentially. Students identify powers and relationships between...

In this parallax effect worksheet, students observe 2 photographs taken of an active area of the sun by 2 STEREO satellites and 1 photograph taken of the same active area of the sun by the SOHO satellite. Students observe the shift in...

Learners determine how force on an object affects its movement. In this force and motion lesson, students take digital pictures of objects in the school setting that are pushed and pulled. They develop a presentation using the digital...

In this algebra worksheet, students review the basic concepts of algebra and linear equations. They solve polygons and shapes for their area and perimeter. There are 27 questions.

In this 8th grade math test, 8th graders complete 27 multiple choice problems. Problems cover a wide variety of concepts from geometry to linear equations and computation with exponents. The test is from 2005.

Students excavate an artifact. In this archaeology lesson, students get a bucket filled with dirt and a broken up artifact. They work in groups to take it out and to find what its purpose was. 

Students investigate simple machines. For this simple machines lesson, students construct two simple machines and describe what they do. Students show that simple changes help machines do work with less effort. Students use a paper clip...

In this algebra worksheet, students solve linear equations using one and two steps. They solve systems of equations using substitution and elimination with graphing. There are links for ready made tests and quizzes.

Students explore intertidal zones. In this intertidal zones lesson, students work in small groups and use ready-made materials to create a model of intertidal zones. Resources are provided.

Second graders design and sketch a model house. For this technology lesson, 2nd graders construct their house using teacher provided materials. They present their finished project and explain their design in class.

Students explore the nature of electromagnetic spectrum through a series of experiments. In this physics instructional activity, students determine how light behaves under certain circumstances. They explain how humans perceive colors.

Students investigate the magnitude of Earth's magnetic field using PASCO. In this physics lesson, students describe the features of the magnetosphere. They explain how atmosphere layers protect the Earth.

Students use triangulation method to locate meteorite landing site on the map. In this earth science lesson plan, students participate in a meteorite treasure hunt set up by the teacher. They explain how this method is used by scientists...

Use Glencoe's randomly generated self-checking quiz to test your knowledge of using angle measures. Each question has a "Hint" link to help. Choose the correct answer for each problem. At the bottom of the page click the "Check It"...
