Paul Andersen explains how to formulate questions to guide discussions and investigations. He starts by describing the proper type of questions that should be asked in an AP Biology classroom. He gives four examples of questions that...

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 video Paul Andersen describes the science practice of data collection. He begins with a brief description of science and the scientific method. He details concepts related to data collection in each of the four big ideas. He...

Explore the nature of science with The Amoeba Sisters. This video discusses why there is not just one universal scientific method as well as the importance of credible sources when researching. Vocab in experimental design including...

Mr. Andersen gives a brief description of the scientific method.

As Psychology is a science, it uses the experimental method in a similar way to Physics, Chemistry and Biology. However, because of the subject matter Psychologists are studying, it can sometimes seem a bit confusing.

Reviewing each part of an investigation.

Pupil outcome: I can explain why it is important for a plant that its seeds are dispersed over a wide area, and carry out an experiment to measure seed dispersal. Key learning points: - Seeds are dispersed by different mechanisms to...

Pupil outcome: I can display data as a graph or chart and identify patterns to conclude on the relationship between the independent and dependent variable. Key learning points: - Experimental data can be analysed by plotting data on a...

Pupil outcome: I can plan an experiment to test the strength of an electromagnet and explain how different factors affect the strength of an electromagnet. Key learning points: - The more turns of wire in the coil of an electromagnet,...

Pupil outcome: I can explain why the heating effect of the Sun is greater at midday than at sunrise. Key learning points: - Heating a surface from directly overhead is more effective than heating a surface at a different angle. - When...

Pupil outcome: I can plot and interpret data points on scatter graphs. Key learning points: - Data is given as pairs of values. - The independent variable is placed on the horizontal axis. - Placing the independent variable on the other...

In this video, we define direct variation and work an example problem.

How can you tell if a relation is a function?

Watch this video for basic definitions and applications of that Algebra ideas of domain and range.

How to solve word problems using point-slope form of a line. Typically, students are very comfortable using slope-intercept form of an equation, but we rarely see examples where using point-slope form is the most efficient. In this...

See how the definitions of domain and range apply to real-world situations.

Algebra 1 STAAR/EOC released test questions. These are practice problems meant to help you review and practice as you prepare for your STAAR test / EOC test for Algebra 1 (Texas). Readiness standard A2A - determine the domain and range...

Now that we know what differential equations are, we have to learn how to classify them. We have to know whether a DE is ordinary or partial, linear or nonlinear, homogenous or nonhomogenous, autonomous or nonautonomous. We have to be...

We have covered three classes of first-order differential equations, those being separable, linear, and exact. There are just two more to go over, those being homogenous and Bernoulli differential equations. What are these, how do we...
