In this video Paul Andersen shows you how to asking questions in a mini-lesson on experimental questions. Two examples are included in the video and two additional examples are included in the linked thinking slides. <br/>

In this video Paul Andersen shows you how to plan and carry-out investigations in a mini-lesson on experimental design. Two examples are included in the video and two additional examples are included in the linked thinking slides. <br/>

In this video Paul Andersen shows you how to plan and carryout investigations in a mini-lesson on evaluating data and design. Two examples are included in the video and two additional examples are included in the linked thinking...

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...

Today we’re talking about how we actually DO sociology. Nicole explains the research method: form a question and a hypothesis, collect data, and analyze that data to contribute to our theories about society.

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...

In this video Paul Andersen explains how you can have your students plan and carry out their own investigations.

Paul Andersen explains how enzymes are used to break down substrates. The correct shape of the active site allows a key/lock fit between the enzyme and the substrate. The enzyme catalase is used to break down hydrogen peroxide. The...

Paul Andersen explains how graphs are used to visually display data that is collected in experimentation. He describes five main types of graphs; line graph, scatter plot, bar graph, histogram and pie chart. He describes the important...

So how do we apply the scientific method to psychological research? Lots of ways, but today Hank talks about case studies, naturalistic observation, surveys and interviews, and experimentation. Also he covers different kinds of...

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.

This video illustrates the analysis of variance, where we will look at the use of this variance in our dependent variables.

This video will look at logistic regression in detail, mainly used for classification problems with one or multiple independent variables.

In this lesson, you will learn to use polynomial regression when linear regression is not working well to report accuracy, using the Bayes information criterion.

After learning about simple linear regression with two variables, we will now look at multiple linear regression using multiple variables.

Let's learn more about one significant measure to determine how well our regressions work using the coefficient of determination.

We've covered the basics regarding second-order differential equations and their solutions, for both linear homogenous and nonhomogenous differential equations. Now let's look at some special second-order types, such as Cauchy-Euler, and...

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 state the difference between interpolation and extrapolation and the limitations of each. Key learning points: - Interpolation can be used to estimate a value within the data set. - Extrapolation can be used to...
