Learners investigate the concept of a macroinvertebrate. They observe the presence of increases or decreases in population in order to test for factors that contribute to the extinction of a species. Students predict the likelihood of...

In this microscope worksheet, students review how microscopes work and how early scientists figured out how microscopes could help them with their discoveries. This worksheet has 3 fill in the blank and 7 short answer questions.

Students investigate and analyze the patterns of sedimentation in the Hudson Canyon students observe how heavier particles sink faster than finer particles. They study that submarine landslides (trench slope failure) are

Third graders identify and define an Ecosystem and the basic needs of all animals. They collect pond water in a pickle jar. They observe the organisms that are in the jar to keep an ongoing record of the creatures and their population.

Students explore their environment. Given a question and a scenario, they conduct a field study of a designated area. In that area, they count and tally the number of insects that are present.

Fourth graders explore the weathering process of water on rocks. They observe how water and friction from other rocks cause them to weather. Students discuss examine and discuss various rocks found on the playground, beach, etc. They...

Ninth graders analyze cars and particulate matter in the atmosphere. They analyze results of particulate pollutants and identify which vehicle gives off more particulates. They identify sources of particulate matter and relate to...

Young scholars list individual properties of solids, liquids, and gases. They examine that some properties have more than one state of matter. Pupils consider whether shaving cream, is a solid, a liquid, or a gas, or some combination.

Young scholars explore organisms and botany by utilizing microscopes. In this microscopic research lesson, students define many plant and organism related vocabulary terms such as conifers, moss and spores. Young scholars view spores and...

Learners explore the parts of a microscope. In this microscope lesson, students examine simple and compound microscopes. Learners discover how the parts of a microscope work together to generate an image.

Second graders examine compost piles and what invertebrates help decompose the organic matter.  In this compost invertebrates lesson students collect invertebrates found in a compost pile and examine them. 

High schoolers explore the basic building blocks of our planet.  In this minerals lesson young scholars begin the process of forensics on the basis of investigation and drawing conclusions from observations. 

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...

Second graders investigate the meaning of temperature. They determine what happens to a thermometer when the temperature rises or falls. They place thermometers in different classroom locations in order to compare the temperature in a...

First graders develop skills of scientific inquiry. They determine which objects float and which sink.

In this microscopes worksheet, students access a website to complete questions about the early compound microscopes and the scientist involved in the development. This worksheet has 1 graphic organizer, 7 fill in the blank, and 10 short...

[Free Registration/Login Required] Learn about the type, size, location, and orientation of the image that forms when a thin lens is used to view an object using this interactive simulation. A PDF worksheet and a video tutorial are also...

Biodiversity can be found in many places, including city parks. At this OLogy learning game site, players use a magnifying glass to find organisms that live there and also learn something about how each organism relates to others nearby.

A discussion of how to make a refraction exhibit using a Fresnel lens. Consists of assembly instructions and a "To do and notice" section.

This is an informative site from Georgia State University. It gives a discussion of the thin lens equation and an illustration of its use in determining the image distance based upon the object distance and the focal length.

Come explore with Elinor! Use the tools provided to observe your environment as you take a nature walk. What will you find?

Students using magnifying glasses to observe collected fossils, and then make inferences and hypotheses about the age of the specimens.

Have you ever mixed together salt and pepper? Isn't it fun to see how all of those tiny grains of salt and pepper mix together. But what if you had to separate them out again? Do you have nightmares of tiny tweezers, a magnifying glass,...
