In this sound activity, learners understand how sound is created and how the human ear "hears." Students compare the frequency, amplitude, and speed of sound. Then learners complete 10 matching, 7 fill in the blank, and 11 short answer...

In this physics 240:10 instructional activity, students calculate the speed and distance as presented in the given word problems. Students apply their understanding of Hooke's law to answer the questions provided.

In this sound worksheet, students read about sound waves, how they are graphed, what frequency is and how it's related to pitch and the speed of sound. Students solve 8 sections of problems including matching terms related to sound to...

In this waves worksheet, students read about harmonic and linear motion in waves as well as the two types of waves. They match 5 terms to their definitions about the structure of waves, they solve for the wavelength, frequency and...

Students examine the importance of good quality safety gear. In this investigative lesson, students will tests various polymers, collect data, and analyze the data to determine which polymer is best for safety helmets. They will design a...

In this P and S waves worksheet, learners use a Slinky to simulate P and S waves showing compressional and dilational motion.

In this conductors and insulators worksheet, learners answer 11 questions about electrical resistance, conductance, gauge scale, and breakdown voltage.

For this conductors worksheet, students complete 15 problems about conductance, strain gauge, and electrical resistance of conductors.

Students use plastic bottles, water, and condiment packets to simulate how natural gas comes from decaying ocean plants and animals. In this natural gas lesson plan, students also fill out lab packets and answer exit questions.

Students examine how sedimentary rocks are formed.  In this rock lesson students research different rock formations and different types of rock. 

Students dissect owl pellets. In this dissecting owl pellets lesson, students discuss birds of prey and make predictions about what they may find during the investigation. Students tease out skull and bones and try to make a complete...

Ways are identified in which exercise benefits the nervous, respiratory, and cardiovascular systems of the human body in this presentation. It also includes definitions for and examples of aerobic and anaerobic exercise, as well as...

Students read first hand accounts of earthquake survivors in order to begin the describe the different types of earthquake waves and the order in which they arrive. They engage in using earthquake waves as a means to indirectly study the...

Young scholars research volcano hazards in VolcanoWorld, make a paper volcano, produce and watch the effects of ashfall, produce and watch the effects of a mudflow and create a hazard map by plotting historical ashfall/mudflow data from...

Second graders watch demonstrations and conduct experiments that show the three different types of rocks: igneous, sedimentary, and metamorphic.

Students, in groups, design and test a scale bridge. They use the Internet to research three basic bridge designs -- beam, arch, and suspension -- and the forces that act upon them.

Learners research and analyze sound waves and how an ultrasound works to image a baby in utero. They explore various websites, complete worksheets, and write a paragraph describing a demonstration they view in the classroom.

Students view a video clip on skyscrapers. They discover how columns support different size loads. They participate in activities and discuss their results.

Eighth graders build a structure that is able to withstand a simulated earthquake. They research earthquakes, earthquake measurement, and society's preparation for and reaction to them. Pupils build models and present them to the...

Students investigate how engineers use different types of bridges for different places. In small groups they design and construct bridges for three different scenarios, and answer a series of investigating questions applied to the...

Middle schoolers conduct science experiments to understand that particle movement changes as a substance changes from one phase to another phase. Students record observations of experiments that involve the three states of matter:...

Young scholars examine amount of garbage disposed of by average household weekly, classify different categories of garbage and describe composition of landfills, investigate what happens to waste after it is collected by garbage trucks,...

Students discover what happens to their trash and garbage once it is collected off of the curb. In groups, they classify garbage and waste into seven different categories and estimate how much waste is created in each one. Using the...

Students are introduced to the processes of evaporation and condensation as they observe physical changes in water. They observe how matter changes from a solid to a liquid state. Students are explained that steam is water in its gaseous...
