Your urine is mostly water, but hidden in there are trace amounts of some very useful stuff!

Farting is hilarious and gross and everyone is doing it so why can't we talk about the science of it?! Flatulence, passing gas, cutting the cheese, toots.... whatever you call it, it's natural and here's how it works.

In this video Paul Andersen shows conceptual thinking in a mini-lesson on physical quantities.

Despite water covering 71% of the planet’s surface, more than half the world’s population endures extreme water scarcity for at least one month a year. Current estimates predict that by 2040, up to 20 more countries could be...

In this math video we will interpret the graph of a proportional relationship. We are given a graph the represents a real world relationship. We will discuss what the variables x and y represent to the real world situation. We will...

Boyles' Law Calculations are EASY! Boyles' Law tells us that there is an inverse relationship between the pressure and volume of a gas. But what does that mean? In this video, we cover Boyles' Law in detail and also go over how to...

The mole is an important concept to understand in chemistry and being able to convert the mole to different units like grams, molecules, ions, atoms or liters is equally important. In this video, we cover the different conversion factors...

Water is a simple molecule, so our body does not have to break it into smaller, simpler molecules to digest it. In fact, water molecules are so small that they have no problem diffusing through the cell membrane. This cell membrane...

Calculating molarity is as easy as plugging numbers into the triangle and using your calculator to either multiply or divide the numbers given in the problem. Calculating molarity is important in chemistry as molarity is a common...

Dive into the metric system's approach to measuring volume, focusing on liters and milliliters as key units. This video explains how these measurements apply to everyday scenarios, like determining the volume of water in bottles and...

Chemistry can be challenging and as with most classes in school, there are some mistakes that pretty much all students make. In this video, we cover these common mistakes to help you avoid them!<br/>

This video will explain the concept of a mole and how to calculate the molarity of a solution using concentration of solutions.

Volume in Cubic Units examines how unit cubes are used to measure volume by writing the units used to find the volume of real-world examples in exponent form (in.3, m3).

Converting Customary Measurements of Mass explores converting measurements of mass using the customary system, including ounces, pounds, and tons.

A video entitled “Problem-Solving Liquid Volume” which demonstrates how to use a number line to solve metric liquid volume word problems.

Upon viewing the Measuring video series, students will be able to do the following: Generally explain that the process of measuring involves making observations of things using tools. Understand that measurements often involve the use of...

This video summarizes the topics covered in the Metric Mass and Volume series. In this program, students differentiate between mass and volume and describe how these are measured in the metric system. They learn how to use measuring...

In this video, we learn about the concept of mass as a property of matter. The video also mentions that mass in the metric system is measured in units of grams, milligrams, and kilograms. This video is part of the 9-part series,...

In this video, students learn how to solve word problems involving mass and volume using multiplication and division. The video provides examples and explanations of the units of measurement for mass and volume, as well as key words to...

In this lesson, students learn how to apply their knowledge of converting measurements and problem-solving to real-life situations, specifically in the context of planning for a soccer game. They explore different metric systems for...

Here, I work an example in which pressure is calculated using the Hard Shell gas model. We then compare it to that calculated using the ideal gas model. ***Next Example='https://youtu.be/DdCoxgpLD3U' target='_blank'...
