Learners are introduced to the basic parts of rockets and the physical forces at work in the flight of rockets. They build and launch a model rocket and discuss the challenges of launching a real rocket.

Students participate in a lesson designed to illustrate these concepts using simple materials. They use Science process skills to observe, measure, predict, make inferences, and communicate while completing the activity. Proper safety...

For this science worksheet, students examine how the universe is bound with the atomic particles and focus upon the findings of two historical scientists.

Young scholars explore aquatic life. In this science lesson, students visit an aquatic ecosystem and collect animals found there. Young scholars create a food chain for the aquatic ecosystem.

Students perform several tests on liquids. In this general science activity, students compare the properties of polymeric and nonpolymeric liquids. They explain the composition and importance of macromolecules.

Thoroughly written, this plan walks you through every detail of having your high school astronomers design scale models of the solar system. Complete instructions on building to scale, lesson procedures, and associated worksheets are all...

Earth's magnetic poles switch positions about every 200,000—300,000 years. In the activity, groups create a planet with a magnetic field. Once made, they use a magnetometer to determine the orientation of the planet's magnetic field....

A radio receives radio signals, converts them to an electrical signal, then converts this signal to a sound signal, and amplifies the sound so people can hear it. Class members use this information to create a short-wave radio antenna...

In the 19th activity of 22, learners determine if distance from a light source affects photosynthesis. Participants capture oxygen in straws and find that the amount of water the gas displaces is proportional to the rate of photosynthesis.

Students inspect the factors involved in blood alcohol concentration. They observe a Web-based driving simulation and discover the physical and mental impairments caused by alcohol. They calculate the blood alcohol content in various...

Students develop a pathogen based upon their knowledge of pathogens and after presenting it to the class, they then suggest ways that the pathogen might be combated. Next they identify possible physical or behavioral changes in a...

Researchers use scientific data to understand what is inside each of the planets. The first in a series of six, this lesson builds off of that concept by having pupils use a data table to create their own scale models of the interiors of...

All of the gas giant's atmospheres consist of hydrogen and helium, the same gases that make up all stars. The third in a series of 22, the activity challenges pupils to make scale models of the interiors of planets in order to...

Huygens spacecraft landed on Saturn's moon Titan in 2005, making it the farthest landing from Earth ever made by a spacecraft. In this hands-on activity, the 12th installment of 22, groups explore how density affects speed. To do this,...

Saturn's rings are made of dust, ice, and solid chunks of material. Individuals use spectrographs in this final installment of 22 lessons to determine the atmospheric elements. They analyze spectrums from Titan's atmosphere and...

By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

Students correlate string tension with sound pitch. They describe how string mass (thickness) effects sound pitch and demonstrate an understanding of the physics of the acoustic guitar. They see that sound is produced by vibrations.

Students role play a power grid set up to show how increased load affects the grid. In this physics lesson, students explain the importance of electricity in their daily lives. They identify the key components of the power grid.

Everything is in the genes. Individuals observe 14 different traits of themselves. Using pipe cleaners and beads, the learners create models of a chromosome representing their traits. The class then compares and contrasts everyone's...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

Take charge of your class and provide them with an electrical experience! Individuals investigate the basic principles of electricity and magnetism by creating a model to test electric current and the amount of electricity generated....

Create a scaled model of our solar system in your classroom! Scholars work collaboratively to build paper mache planets and hang them in their proper position to showcase each planet's location in the solar system.   

Middle schoolers analyze given data on density and diameter of objects in space by graphing the data and then discussing their findings. This ninth installment of a 22-part series emphasizes the Galilean moons as compared to other...

When given too much data to simply memorize, it helps to sort it into manageable groups. The second lesson in the six-part series of Cosmic Chemistry challenges groups of pupils to take a large amount of data and figure out how to best...
