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...

You've probably heard of fool's gold, and it might make you think of prospectors in old timey California seeking their fortunes. But there's another kind of fool's gold called chalcopyrite, and lucky for those that want to strike...

👉 Learn how to evaluate the limit of a function involving rational expressions. The limit of a function as the input variable of the function tends to a number/value is the number/value which the function approaches at that time. The...

One of the most important processes in science is the art of observing. This video highlights different ways observations are made, emphasizing methods by which students can observe their world. Different types of data, how data is...

The simplest organisms can still accomplish wonders.

Susan Blackmore studies memes: ideas that replicate themselves from brain to brain like a virus. She makes a bold new argument: Humanity has spawned a new kind of meme, the teme, which spreads itself via technology -- and invents ways to...

Today we're going to start our two-part unit on data visualization. Up to this point we've discussed raw data - which are just numbers - but usually it's much more useful to represent this information with charts and graphs. There are...

Paul Andersen explains how scientists analyze and interpret data. Data can be organized in a table and displayed using a graph. Students should learn how to present and evaluate data.

Paul Andersen shows you how to graph data by hand. He explains the required elements of a scatter plot with a best fit line. He shows you how to properly scale and label the axes.

Unlike Earth, our Sun is a giant ball of mostly hydrogen and helium. Astronomers managed to figure that one out roughly 100 years ago. But after all this time, they still can't come to an agreement on what "mostly" means, precisely.

In this video Paul Andersen explains the difference between diploid and haploid cells. He starts with a brief description of the central dogma and how genes code for proteins. He then uses the phenotype of red hair to explain that...

Composite functions



In the introduction to functions video, we discovered what functions are, what domain and range mean and how to solve some

problems.

We saw that they could be called f(x) or
g(x) or any...
