In this short video we will answer a standardized test question by rewriting a value in scientific notation to standard form.

This video provides the solution and explanation to the hypothesis testing practice exercise we worked on above.

In this video, we learn how to convert a number written in scientific notation to standard notation. The teacher explains the process step-by-step and shows an example of converting 8.25 * 10 to the 5th to 825,000.

In this video, the teacher explains how to use the vertical line test to determine if a graph is a function or not. The viewer is presented with four graphs and asked to identify which one is not a function. The teacher demonstrates...

In this short video, we will solve a standardized test question by writing a proportion. We will identify key terms and review proportional relationships.

In this short video we will answer a standardized test question using order of operations. We will rewrite subtraction to add the opposite. We will learn that we can add repeated addition in any order. We will add the positive values...

In this short video lesson we will answer a standardized test question using the commutative property. We will consier all the multiple choice answers. We will identify that the left side of the number sentence is the same for all...

In this short video, we will solve a standardized test question about finding rate in miles per hour. We will learn that rate is a ratio. A ratio that is divided will become a unit rate or miles per one hour.

Paul Andersen explains the importance of modeling in science and engineering. Models are used by scientists to explain phenomenon. Unlike mental models, conceptual models can be shared by all scientists to improve our understanding of...

Paul Andersen explains how investigations are used by scientists to answer questions and by engineers to test designs. He delineates be investigative and observational science. He demonstrates the formation of a good question the...

In this short video we will answer a standardized math test question where we are asked to identify the equivalent expression. We will review how to divide by a fraction using the rule multiply by the reciprocal or also known as keep,...

In this short video we will answer a standardized math test question using similar figures to find a missing dimension of a rectangle. We will review that similar figures have corresponding sides that are proportional. We will use the...

In this short video we will answer a standardized math test question where we are given an algebraic expression that represents a real world situation. We are asked to recognize and identify which solution represents a simplified...
