Students calculate the tangent ratio given a right triangle. For this trigonometry lesson, students use a right triangle and the Pythagorean Theorem to solve problems.

Students describe the differences between an estimate and a guess. They create reasonable estimates based on comparison and activities. Students explain how estimation is helpful in showing the relative size on a scale. They also...

Young scholars perform an experiment with different types of bird eggs to determine what factors make them strong and able to stay on a cliff without rolling off.

Students study the relationship between the heart and circulation. In this circulatory system lesson plan, students read the "What Am I?" article about the heart and discuss. Students draw a heart and lungs, discover how blood is...

Students examine several concepts about weather in the seven lessons of this unit. This year long activity helps students to gather data seasonally about wind, clouds, precipitation, and temperature. Earth's three climate zones are...

In this acceleration worksheet, students experiment with varying amounts of mass to observe the effects on the force needed to move an object. Students apply Newton's Second Law of Motion to describe the relationship between mass and...

Students construct aluminum foil boats that float while holding the greatest number of pennies. They investigate the concept of water displacement, record their results, and watch a Bill Nye video on buoyancy.

Students are introduced to the notion of surface area and volume, learn the terminology used with surface area and volume and have experimented with the surface area and volume of different prisms.

Students investigate the loom and weaving process. For this weaving lesson, students use soda straws to make a bracelet or a bookmark. Students use the over-under pattern of weaving.

Students define area and perimeter. They demonstrate understanding of the concepts concretely, with manipulatives, and describe with words, their strategies and thought processes.

Students examine the behavior of living cells treated with different types of stimuli. They watch an online movie, examine wet mount slides under a microscope, take an online quiz, and analyze data.

In this variables worksheet, students are given seven experiments that they read and identify the independent variable, dependent variable, control group and standardizing variable.

Students explore the relationship between a scale drawing and actual distance. In this mapping instructional activity, students use an amusement park map to determine distances and what they would be like in real life.

Learners become forensic investigators. In this crime scene lesson, students go to the science lab which is the "scene of the crime." They collect evidence such as fingerprints, "blood" evidence, chromatography, footprints, and more. 

Students watch video, The Elements, research information about elements using both the Internet and CD-ROM program, and create atoms out of gumdrops and licorice.

Students use video learning and construct electromagnets and use them to collect data, graph, and share with others.

Sixth graders explore the causes and effects of earthquakes. They also collect and analyze data in graphs. They also use the Internet to research earthquakes

Third graders keep a journal and record the growth of their plant everyday over a two week period. With an observation written down for everyday of the week, they draw a picture of their plant in their journal on Monday and Friday...

In this constructing triangles online learning exercise, students construct thirteen triangles on paper first and then type in their answers on line. Students can check their answers as they go and the computer calculates the overall...

Tenth graders investigate the relationships of pressure and volume and pressure and temperature of gases. In this gases lesson plan, 10th graders use an inflated balloon to show the relationship between volume and temperature of the air...

Students discover the power of wind by flying a glider.  In this weather lesson, students describe their thoughts on wind and practice using weather related vocabulary.  Students construct model gliders in class and attempt to...

In this electrical circuit worksheet, students research the Federal Communication Commission to determine the regulations for a non-license radio transmitter. They will answer a series of another 3 questions to show an understanding of...

Tenth graders investigate the theorems of ASA, AAS, AAA and ASA. In this geometry instructional activity, 10th graders discuss the theorems of triangles and how it is used to solve for missing sides or angles. They review how two angles...

First graders complete a variety of experiments with solids, liquids and gases. They read books about matter, identify the characteristics of solids, liquids and gases and the sort and classify a variety of matter. Students make...
