The 15 refracting telescope featured in this video was built by the Warner and Swasey company of Cleveland, Ohio. It was originally located at Ottawa's Dominion Observatory.
The scientific method begins with an observation, which leads the scientist to ask a question. Learn how scientists create controlled experiments to answer their questions.
Today, we're going to talk about five common types of algorithmic bias we should pay attention to. Bias can become a problem if we don't acknowledge exceptions to patterns or if we allow it to discriminate.
Data visualization is the visual representation of data and information. It helps to uncover insights that may go unseen when observing the data alone.
Our ethics help us to be kind, truthful, and fair. Scientists also have ethical “rules” to follow to ensure that their research—and the powerful technologies that spring from it—are used to help people, not harm them.

There was something special about Henrietta Lacks' cells that made them especially good for research. But should scientists have taken them without permission?
In this guided online lesson, students will learn the steps of scientific research, what scientific integrity is and why it matters from a health information perspective.
Data and graphing exercises extend previous graphing skills (double bar and line graphs, line plots and circle graphs with fractions) and introduce basic probability and statistics (range, mode, mean, median).
