The resource investigates predicate calculus. The tutorial examines propositional calculus, universal quantifiers, mathematical statements, and divisibility. Students learn about the logic concepts through notes and examples. Practice...

Read about the use of data loggers in one high school class. The data loggers were the key to quantifying the relationship between temperature, light, and biodiversity. Although this is relevant to high school science links are provided...

This tutorial reviews how to calculate molecular formula by giving students video, exercises, and practice.

Learn how to balance equations in this tutorial. Tutorial includes videos, interactive activities, and practices.

Light is an example of an electromagnetic wave. Electromagnetic waves can travel through the vacuum of interstellar space. They do not depend on an external medium-unlike a mechanical wave such as a sound wave which must travel through...

This interactive tutorial illustrates how spectrometry is used to study, identify, and quantify materials.

An introduction to the mole, a unit of measurement that quantifies atoms and molecules.

[Free Registration/Login may be required to access all resource tools.] In this learning module, students investigate the mole concept, and learn three ways scientists to quantify things as tiny as atoms.

Students take a journey through our physical world, beginning with the ways in which people quantify and model mathematically the existence and interaction of physical objects.

Learn the definitions of a solution, solute, and solvent. Understand how molarity is used to quantify the concentration of solute, and comcalculations related to molarity.

A learning module on wage inequality based on gender. It includes several supporting questions accompanied by formative tasks and source materials, followed by a summative performance task. Students examine the difficulty in quantifying...

Students teams use a laparoscopic surgical trainer to perform simple laparoscopic surgery tasks (dissections, sutures) using laparoscopic tools. Just like in the operating room, where the purpose is to perform surgery carefully and...

Students quantify the percent of light reflected from solutions containing varying concentrations of red dye using LEGO MINDSTORMS NXT bricks and light sensors. They begin by analyzing a set of standard solutions with known...

Students study the physical properties of different fluids and investigate the relationship between the viscosities of liquid and how fast they flow through a confined area. Student groups conduct a brief experiment in which they...

Students are introduced to measuring and identifying sources of air pollution, as well as how environmental engineers try to control and limit the amount of air pollution. In Part 1, students are introduced to nitrogen dioxide as an air...

Two lessons and their associated activities explore cellular respiration and population growth in yeasts. Yeast cells are readily obtained and behave predictably, so they are very appropriate to use in middle school classrooms. In the...

In this project, students are challenged to answer the question "Is there a way to detect the presence of tumors that isn't as painful as mammography but more reliable and quantifiable than a breast-self exam or clinical breast-exams?"....

This lesson plan is the second of two that explore cellular respiration and population growth in yeasts. In the first lesson plan, middle schoolers set up a simple way to indirectly observe and quantify the amount of respiration...

This site discusses the economic, personal, and retirement goals of an entrepreneur. The importance of goals and quantifying them in relation to business plans are linked.

Learn about selective pressure and how genes are involved in adaptations by watching this video on pocket mice. The video focuses on the research of Dr. Michael Nachman, "whose work in the field and in the lab has quantified the...

While this 10-question multiple choice quiz is published to accompany Glencoe's Physical Science textbook, it covers the basics of matter classification taught in any course. Written in standardized test style, learners can take the...

Concepts of waves and sound are thoroughly presented in animation and film clips.

A summary of error and uncertainty considerations, presented at an annual mathematicians' meeting. Not terribly deep, and covers the gamut of concerns about modeling of the real world with inadequate data or math tools. On target. This...

The following tutorial provides an explanation of classification of matter by composition.
