Understanding Acceleration and Motion

In this 8th grade science video, students Allie, Katherine, and Amanda introduce a project on motion and acceleration. They build carts from Legos to fit their phones, use an app to measure acceleration, and analyze the data. The app, Spark Boo View, helps them graph velocity and speed, showing how steady or variable the motion is. The video explains how to interpret these graphs, with small lines indicating steady speed and larger lines showing increased speed or bumps.

What was the main purpose of building the Lego carts in the science project?

• To create a fun toy for students

• To measure the weight of the phones

• To study the concept of acceleration

• To test the durability of Legos

What was placed inside the Lego carts to help measure acceleration?

• A small camera

• A smartphone with an app

• A GPS tracker

• A weight sensor

How did the students plan to use the acceleration data collected from the app?

• To compare it with other schools

• To create a presentation for parents

• To analyze it in the next class

• To publish it in a science journal

What does it mean when the graph lines are small and steady in the app?

• The speed is increasing rapidly

• The cart is not moving

• The cart is going downhill

• The speed is steady and smooth

What is indicated by larger graph lines in the app?

• The cart is accelerating or encountering a bump

• The cart is reversing

• The cart is slowing down

• The cart is moving at a constant speed

What is the name of the app used to graph velocity and speed in the project?

• Speed Tracker

• Velocity Viewer

• Spark Boo View

• Motion Monitor
