Students explore the use of microscopes and the creation of slides. They practice using, adjusting and viewing with a microscope. they view slides of familiar substances such as blood and fibers. In addition, they create slides using...

Students view the video "The Invisible World" and discuss different types of microscopes and what can be seen with each type. They work in pairs to view several objects with a microscope.

In this microscope worksheet, students read about how the electron microscope was created and how it works. Based on the reading, students complete 2 short answer questions.

For this human cells worksheet, 7th graders complete a science experiment using human cheek cells. Students sketch the cells at high and lower power and label the cell nucleus, cytoplasm, and cell membrane.

In this planets worksheet, students read information about Uranus, Neptune, and Pluto and then complete 18 multiple choice, 4 true or false, and 2 fill in the blank questions.

Students predict the measurement of objects. In this measurement lesson, students estimate the measurements of objects in a lab. Students measure irregular objects and generate scientific observations.

Students analyze lunar material using actual moon rocks that were brought back by Apollo astronauts. The teacher and student activity sheets are well-designed.

Students create the illusion of texture using lines, dots, and shapes in a rendering of an animal.

Students examine digital images and how satellites orbiting Earth send information and pictures to Earth over the Internet. They use a digital camera to put pictures on a computer and decode a satellite image from space.

Middle schoolers examine the properties of magnets and static electricity. They participate in experiments that demonstrate the behaviors of charged particles, and record their data on a worksheet.

Sixth graders compare distances between objects in the solar system. They investigate how light years are measured and when using them to measure how distances compare with one another. They write an essay exploring the possibility of...

Students use laboratory equipment safely. They identify structures in a seed. They distinguish between monocots and dicots. They search for information using the computer.

Young scholars are introduced to alternative methods of growing techniques: specifically, hydroponics. They, in groups, "adopt" a seed. They take care of their seed and make observations as it begins to germinate.

Second graders examine how food chains interact with different plants and animals. They practice using new vocabulary. They also discover the role of pesticides in the environment.

Third graders are introduced to the topic of matter. As a class, they brainstorm what they already know about matter and its properties. After completing a worksheet, they participate in an experiment in which they observe matter in...

Students identify protists under a microscope, and using a stopwatch calculate the speed of a protist from a pond water sample. They use distance and time to identify the speed of a protist, and create a distance versus time graph to...

High schoolers collect samples of common dust from their homes and school for examination under a microscope. They identify the components of their samples using the provided "Atlas of Indoor Dust Particles." Pupils take samples form a...

Students investigate the variety and amount of particulate matter in the air. They locate the general sources of pollution for a specific area and develop some suggestions for improving air quality.

Students prepare successful wet mount slide of Elodea. They determine and identify environmental conditions that induce cytoplasmic streaming. They determine the positive aspects of cytoplasmic streaming. They illustrate knowledge and...

Students analyze and record major events that occur in the development of Medaka fish eggs from fertilization to hatching. In small group, students describe the processes involved, creating a timeline of the major events in the...

Students apply real data to create and calculate algebraic equations. Students create a visual to represent the concentration for one part per million and apply unit analysis to verify measurement computations. Students define the use...

Students recognize and name the parts of a flower. They explain the function of each part of a flower. Students list the steps that occur for sexual reproduction of a plant to take place. They recognize and name the male reproductive...

Students explore the world of fractal images and the mathematics behind them. They explore fractal sites on the Internet. They create their own fractal designs. They publish a calendar displaying their favorite fractal art.

Students observe how the bean seed has changed after being soaked in water overnight and record their observations. They open the bean and observe the inside. Finally, students draw and label the parts of a bean seed and write the...
