Time Problems and Dimensional Analysis

What do you do to change arrival times of airplanes when a different route is not available? The fifth interactive in a series of six presents problems where pupils must find solutions to conflicts of safety rules. They must decide how...

How do we predict future population growth? Young researchers investigate various factors affecting the size of our population. As they calculate and interpret graphs to determine factors that could potentially affect increases and...

In this science and engineering instructional activity, students use dimensional analysis to solve each of the problems stated on the sheet. They illustrate their work and how they arrived at their answers by using significant figures...

Is your class in another dimension with regards to dimensional analysis? Give them some extra practice with a straightforward activity. Learners convert units by following concise step-wise examples, including setting up the problems....

How many dimensions are there? Latitude, longitude, and altitude are accepted dimensions, but what about time or another type of dimension? An engaging video describes how we theorize that we live in three dimensions and which laws of...

Converting from moles to number of particles doesn't have to be difficult! Watch as a video briefly explains the concept of conversion factors. It uses a more common conversion of miles to feet as an example to introduce conversion factors.

Time to discover a new dimension—dimensional analysis that is. After discussing the need for dimensional analysis, the video lesson describes the process by giving a general setup. The instructor then demonstrates examples in both...

Time isn't considered a property of physics, but rather a feature. Sean Carroll explains how we remember the past but not the future; yet we still consider time a dimension in physics. The video offers a brief overview of entropy and the...

Use real-time data to study factors that affect weather and climate, create weather instruments, and share data with students around the world.

What variables change heart rate? Young scientists observe the beating heart in Daphnia to understand these variables. They make changes in temperature, chemicals, and other factors as they graph the heart rates. Analysis questions help...
