Physics Classroom is making strides to make our site accessible to everyone. Our site contains 6 navigation areas. The Primary, Secondary, and Page Level navigations have a screen reader version of their nav structure that allows using the left and right keys to navigate sibling navigation items, and up or down keys to navigate parent or child navigation items. The others can be navigated using tabs. The Primary Navigation handles the first 2 levels of site pages. The Secondary (which is not always available) handles the 3rd and 4th level of structure. The Page level navigation allows you to navigate the current page's headings quickly. The Header Navigation contains the Light/Dark Mode toggle, Search, Notifications and account login. The Breadcrumb Navigation contains the breadcrumb of the current page. If the current page has a breadcrumb, you can get to it by skipping to the content and tabbing in reverse (shift plus tab). The Footer Navigation contains links such as Privacy, Contact, about and terms. Some resources contain an Audio Player that can be activated by holding down the T key for 3 seconds, and then using K to pause and resume. While not every area of Physics Classroom is usable purely from keyboard and screen reader, we are committed to continue work on making this possible. If you have questions or need additional help, please use this link to contact us.

About the Cart, Bricks and Bands


Highly Recommended

Like all our Science Reasoning Center activities, the completion of the Cart, Bricks, and Bands activity requires that a student use provided information about a phenomenon, experiment, or data presentation to answer questions. This information is accessible by tapping on the small thumbnails found on the bottom right of every question. However, it may be considerably easier to have a printed copy of this information or to display the information in a separate browser window. You can access this information from this page. 






The Standards

The Cart, Bricks, and Bands task describes a collection of equipment made available for investigating the effect of mass and of net force upon the acceleration of an object. This NGSS-inspired task consists of two activities. Each activity involves a different type of skill or understanding. Collectively, these two activities were designed to address the following NGSS performance expectation:


HS-PS2-1:

Analyze data to support the claim thatNewton’s second law of motiondescribes the mathematical relationship amongthe net force on a macroscopic object, its mass, and its acceleration.




As a whole, the questions in this task address a wide collection of disciplinary core idea (DCI), crosscutting concepts (CCC), and science and engineering practices (SEP). There are 36 questions organized into 9 Question Groups and spread across the two activities. Each question is either a 2D or (preferrably) a 3D question. That is, the task of answering the question requires that the student utilize at least two of the three dimensions of the NGSS science standards - a DCI, a CCC, and/or an SEP.


The following DCI, SEPs, and CCCs are addressed at some point within Cart, Bricks, and Bands:


DCI:  PS2.A: Forces and Motion 

Newton’s second law accurately predicts changes in the motion of macroscopic objects. 


 

SEP 1.1:  Developing and Using Models

Ask questions that arise from careful observation of phenomena, or unexpected results, to clarify and/or seek additional information.



SEP 3.2: Planning and Carrying Out Investigations

Plan and conduct an investigation individually and collaboratively to produce data to serve as the basis for evidence, and in the design: decide on types, how much, and accuracy of data needed to produce reliable measurements and consider limitations on the precision of the data (e.g., number of trials, cost, risk, time), and refine the design accordingly.



SEP 4.1:  Analyzing and Interpreting Data

Analyze data using tools, technologies, and/or models (e.g., computational, mathematical) in order to make valid and reliable scientific claims or determine an optimal design solution.


SEP 4.3: Analyzing and Interpreting Data

Consider limitations of data analysis (e.g., measurement error, sample selection) when analyzing and interpreting data.


 


CCC 1.5:  Patterns

Mathematical representations are needed to identify some patterns.



CCC 3.2:  Scale, Proportion, and Quantity 

Algebraic thinking is used to examine scientific data and predict the effect of a change in one variable on another (e.g., linear growth vs. exponential growth).
 




Here is our NGSS-based analysis of each individual activity of the Cart, Bricks, and Bands Science Reasoning task. The core ideas, crosscutting concepts, and science and engineering practices that we reference in our analysis are numbered for convenience. You can cross-reference the specific notations that we have used with the listings found on the following pages:

 

Disclaimer: The standards are not our original work. We are simply including them here for convenience (and because we have referenced the by number). The standards are the property of the Next Generation Science Standards.

 

Part 1: Planning the Investigation

This activity consists of 16 forced-choice questions organized into four Question Groups. Students must evaluate a variety of experimental design questions. 


NGSS Claim Statement: Plan an investigation to produce data that serve as the basis for evidenceregarding the rmathematical relationship betweenthe mass of an object, the net force exerted on it, and the acceleration it experiences.
