Science Reasoning Center - Momentum

You have reached the Construction Zone. As of April 1, 2023 the redo of our Science Reasoning Center was elevated to our top priority. We should have a large amount of content ready by August 1, 2023. We release content once it is ready, allowing teachers to preview and to test our latest creations for potential adoption into their curriculum and unit planning. You can stop by periodically to view our progress. It will be like watching a skyscraper being built ... only more exciting. You can also keep abreast of our developments by a periodic visit to the What's New at TPC? page

The Legacy version of the Science Reasoning Center can be found here.

The following activities are planned for our Grand Opening. Once construction is completed, we will include a link to the activity:

Marshmallow Launcher

This activity describes an experiment in which students alter and test variables that impact the effectiveness of a marshmallow launcher. Data is provided in the form of a table and two diagrams. Questions target a student's ability to identify the effect of changes in a variable upon an outcome, to identify dependent and independent variables, to interpolate and extrapolate from provided data, to understand the design of an experiment, to draw conclusions that are consistent with the provided data, and to extend the findings of an experiment to a new situation.


Air Bag Inflation and Passenger Safety

This activity describes the factors that affect the safe functioning of air bags. Data regarding delay time before inflation, inflation rates and inflation pressures are presented in the form of a table and a graph. Questions target a student's ability to find basic information in a body of text, to recognize patterns within a table of data, to draw conclusions that are consistent with data, to translate information from a table to a graph, to interpret the slope of a graph, and to recognize the implications of experimental findings.


This activity describes two experiments in which the inelastic and elastic collisions of two carts on a track are investigated. Mass, pre-collision velocities, and post-collision velocities of the carts are described using two data tables. Questions target a student's ability to understand the experimental design, to identify the effect of one variable on another, to draw conclusions consistent with the data, and to interpolate and extrapolate from the given data in order to predict the result of additional trials.
