Using the Microscope

Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to...

Rise and shine! Class members collaborate to construct a photovoltaic solar cell with two semiconductor layers, as guided by this fabulous lab sheet. They test its output with an ammeter or galvanometer. 

What a packed lesson! Provide your class with the opportunity to learn about the cell cycle in several exciting ways. Biologists first learn about the theory behind mitosis, then proceed to view onion tips under the microscope and create...

Incorporate multiple facets of the cell into your next high school lab! Through an introduction to cell organelles, class members observe each cell type and draw visuals to further demonstrate understanding of cellular processes in both...

This is not they typical set of teacher instructions. It is an organized chart of the important organic compounds. For each, the involved elements, the name of the building block monomers, the names of polymers, extra information, and a...

This exam touches upon every topic within the typical first year biology course.. A broad variety of question styles give high schoolers every opportunity to show what they know. Why start from scratch when a comprehensive final exam is...

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on an entire year's curriculum when they take this thirteen page test. 

Life science learners investigate live cells. They examine wet mount slides of cyanobacteria and Elodea plants. They peer into the dynamic microscopic world of protists. Afterward, they construct a model of a cell, including rudimentary...

Searching for simple ways to teach mitosis to high schoolers? Using colored chalk and onion root tips, pupils visually demonstrate what they view when looking through the lens of a microscope. There are also various ways to expand the...

Get up close and personal with human cells with this lab worksheet. Learners use a microscope to examine their own cheek cells, drawing diagrams of the cells and identifying the parts when they have focused in on a visible specimen....
