Graphical Determination of Density
Students determine the density of metal shot by a graphical method using significant digits in making measurements and calculations. Students graph a seris of laboratory measurements and determine density from a mass verses volume graph.
Curated OER
From Molecules to Mole Day Do's
Students recognize methods used to define the mole. After converting various quantities to the mole, students provide a context for understanding the usefulness of scientific notation and the mole.
Curated OER
Autumn
Students examine the cycle of nutrients in a forest. They research the concepts of decomposing and recycling within a forest.
Curated OER
Extraction of DNA from White Onion
Students conduct lab test with minced onion to determine where chromosonal DNA is located within the cell, and whether or not it can be extracted.
Curated OER
The Same but Different Part II
Third graders experiment with beakers of water and balloons to measure the volume of the gas in the balloon. They determine ways to change the volume of air in the balloon which changes its size but not its physical state. By heating the...

Why is it important to study Biology?
Students study the importance of biology. In this biology lesson plan students write an essay on biology and its importance.
Curated OER
To Float or Not to Float - A Lesson on Density
Learners define density in their own words. In this physics activity, students calculate density using mass and volume. They explain why some objects sink and some float.
Curated OER
Weather is Cool, Hot or Somewhere In-Between
Students access the Internet to record data on weather. They use email to answer a younger classes' questions about the weather.
Curated OER
Ideal Gas Law
Students explain and use ideal gas law and use the law to solve problems. They use conversion factors to convert mass to mol. Also students use stoichiometry skills previously learned.
Curated OER
Selecting Soil Organisms in Compost
Learners conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...
Curated OER
Selecting Soil Organisms in Compost
Students demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment...
Curated OER
Names in the Field: A Simple GPS Field Exercise
Pupils explore basic methods of GPS data collection, uploading the data to a computer, and making simple maps of their data using GIS software. They create a map of the data using GIS software (or Excel)
Curated OER
Wig-wag Physics
High schoolers make observations on the effects of a small, medium and large weight on the movement of a wig-wag apparatus. They use their observations to develop a generalized inference of the effect weight on movement patterns.
Curated OER
Toxicology 2: Finding the Toxic Dose
Young scholars brainstorm with group partners to decide upon a chemical they would like to test, and outline a procedure for their investigation. They then present in groups their ideas to the rest of the class as well as the chemical...
Curated OER
The Code of Life
Students study genes, DNA and medical research. They watch "The Code of Life" video and answer discussion questions regarding the transcription and translation of DNA and how errors in these processes and mutations in DNA can produce...

History Theory of Evolution
Students identify fossils. They identify evidence of change over time when given pictures of fossils to determine the proper sequencing. In addition, they determine evolutionary relationships by comparing embryonic structures.
Curated OER
Consider the Issues
Students develop and express opinions on personal and societal issues in biology through journal entries (written and other forms), oral position statements and group discussions.

Good Vibrations
Students demonstrate sound waves and make changes in the waves
resulting in changes in pitch. Students associate changes in pitch in various "musical instruments"with size and shape and the sound waves they produce.
