Columns have been used throughout the world because they are good load-bearing structures. Learners with visual impairments conduct an experiment to work through the design process as well as to understand this engineering phenomenon....

After choosing one experiment from the four they conducted in the previous lesson, young investigators analyze the evidence they collected to determine if it proves or disproves their original hypothesis.

As an introduction to the hypothesis and testing method of investigation, young history detectives engage in a special investigation of a family artifact. After watching a short video that demonstrates the method, they develop a...

Are sickle cell disease and malaria related somehow? Scholars learn about both illnesses and the hypotheses that they are related. They discuss, view a video, and answer questions to demonstrate understanding. The resource includes an...

If the methodology is skewed, the results will be skewed. That's the takeaway from an exercise designed to get class members thinking about research methods and statistics gathering. Instructors manipulate the testing environment to...

What do lemurs do best? They move! Lemurs like to jump, run, hop, and climb and it's your class's job to document seven fun lemur behaviors. The class starts by discussing why lemurs are considered primates, and then they isolate seven...

Do flexible circuits change dimensions during fabrication? Groups use GeoGebra software to measure the length of pictures of flexible nano-circuits. To determine if the circuits change dimensions, future engineers use Microsoft...

Students analyze information from a variety of sources in order to create a hypothesis about the origin of an interesting family artifact. They create alternative hypotheses based upon available information in order to understand that...

What's that lurking in the shadows? An activity that demonstrates how eclipses happen. Science scholars investigate how light and distance interact to form shadows. The experiment uses simple materials to generate data and observations...

Does increasing the pressure between two moving plates provide a stabilizing force or create more destruction? The hands-on lesson encourages exploration of strike-split fault models. The sixth lesson in a 20-part series asks...

Make pathogens and the body's defense systems come alive for young biologists in a hands-on activity. Investigators model the skin's protection against infection by observing and comparing changes in a punctured tomato and an intact...

Students complete a personal interview in order to discover important information about family history and interesting family artifacts.They analyze statements from the interview in order to prove the accuracy of these statements, as...

This set covers the logic of significance/hypothesis tests. Students decide whether a one- or two-tailed test is appropriate. They also decide, by comparing the p-value to the alpha level, whether statistically significant evidence exists.

Based off of the hit television show NUMB3RS, this lesson has students examine cancer rates in population samples of the New England states to determine if the states' cancer rates are statistically similar. Hypothesis testing is...

Based off of the hit television show NUMB3RS, this lesson introduces students to the chi-squared statistical analysis. Although not completely in depth, the lesson does expose students to degrees of freedom, a simple chi-squared formula,...

In this experiment you will attempt to reproduce Galileo's results using the inclined plane. You will test three hypotheses relating to motion on an incline. You will learn to draw a "best fit" or regression line of experimental data....

This set contains questions about statistics regarding one- and two-sample t-distributions. The student learns to develop hypotheses, find the test statistic, and reach a conclusion in the context of the original problem.

Based off of the hit television show NUMB3RS, this lesson introduces students to the odds ratio, a method in statistics for determining if the findings of two groups are statistically significant to each other. Students will find...

Identify simple principles of physical science and engineering by exploring ramps and things that roll. Predict which items will slide or roll down a ramp and test your predictions.

Find games and flashcards that students can use to learn the words associated with the scientific method.
