Sixth graders study microorganisms. In this microorganism lesson, 6th graders explore the form and function of these organisms. Students use magnification during experiments on bread.

Students project and measure the suns image using a refracting telescope.  In this sun's diameter lesson students calculate the magnification of the telescope and determine the diameter if the Sun. 

High schoolers perform a classroom activity of measuring the angular size of something from several distances. On the Internet, they obtain and examine images with various magnification factors and estimate the angular size of Andromeda.

Learners recognize slides of different fungi. They work in lab groups. Students view slides under the microscope, then draw and label the parts, magnification, and the organism. Learners discuss similarities between some fungi and...

Students view salt under varied magnifications so students can begin to construct the understanding that materials may be composed of parts that are too small to be seen without magnification.

Students identify the characteristics of mirrors and lenses. In groups, they describe the types of images formed by converging and diverging mirrors and calculate the magnification of a spherical mirror. They follow the same procedure...

Students investigate issues of degradation and weathering of polymeric materials during their useful life. They evaluate photodegradable plastics and their viability as an environmental solution for litter and investigate the qualitative...

Students explore DNA restriction mapping. They cut pieces of paper into lengths representing those produced when specific enzymes are used to cut a strand of DNA.

Students examine parts of a microscope and how to use a microscope at five lab stations. They identify parts of a microscope by describing the differences between low power and high power. They visit Internet sites (included in the...

Learners explore about propagation of error in calculations using experimental data. They develop their weighing and pipetting techniques. Students explore the following terms: Standard deviation and relative standard deviatin. They...

Learners explore the strength of intermolecular attractions. They make slime and compare the difference in the physical properties of sheet and powdered polyvinyl alcohol with polyvinyl acetate.

Students are introduced to how the differences in solubility of materials are used in the manufacture of fibers and films. They are also introduced to the various processes used to make films and fibers. Pupils prepare fibers using wet...

The intent of this series of activities is to introduce high schoolers to the field of chemical instrumentaiton. They perform a few basic chemistry lab techniques: pH titration, paper, gas, and liquid chromatography, ultraviolet and...

Young scholars treat a high molecular weight polyvinyl alcohol polymer with potassium periodate. They measure the viscosity of polyvinyl alcohols.

Student demonstrate knowledge of recombinant DNA techniques (restriction enzyme digest, gel electrophoresis, and staining gel). They demonstrate skills needed to complete a gel electrophoresis and interpret a stained gel. Pupils solve...

In this science worksheet, students calculate the size of different samples using the microscope as part of a formal lab assignment.

Young scholars work as a team to use the ProScope Digital USB Microscope and a computer to collect microscopic images from a variety of organisms. When they compare these specimens, they are able to determine how they are alike and...

Students compare fossilized specimens to contemporary specimens. They use a computer and a Proscope Digital USB Microscope to collect and compare images of ferns, sand dollars and sow bugs to those of similar fossilized samples.

Explore the powers of ten while examining a Blue Morpho butterfly wing. Learners discover there is a lot more than meets the eye when one looks close enough.

Psychologists study human relationships while ecologist study relationships between organisms in the environment. An introduction to ecology and the related vocabulary benefits scholars as they progress through the presentation and...

In this microscope worksheet, learners complete 15 review questions of labeling, defining and short answer after finishing a compound microscope lab. Lab included.

Students participate in a lab activity in which they examine a simple energy transformation system. Students test the rebound of elastomers, produce rebound data, and determine the kinetic energy transformed by the impact of a free...

Students collect microscopic images from a variety of chemical specimens to determine the identity of a mystery powder. They use a ProScope Digital USB Microscope to describe and compare the crystal size and shape of the chemicals.

Students work in pairs to construct a simple stereoscope.
