Fourth Grade PLTW

Hughes, Steven - Technology / Overview
Module 1: Energy Collisions

Students explore the properties of mechanisms and how they change energy by transferring direction, speed, type of movement, and force. Students discover a variety of ways potential energy can be stored and released as kinetic energy. They explain the relationship between the speed of an object and the energy of that object, as well as predict the transfer of energy as a result of a collision between two objects. The design problem is introduced by Angelina, Mylo, and Suzi watching amusement park bumper cars collide. As students solve the problem for this module, they apply their knowledge and skills to develop a vehicle restraint system.© 2016 Project Lead The Way, Inc.

Module 2: Energy Conversions

Students identify the conversion of energy between forms and the energy transfer required to move energy from place to place. They also identify and explain how energy can be converted to meet a human need or want. The design problem is introduced through Angelina, Mylo, and Suzi, who need to move donated food fro a truck to a food pantry. Students then apply scientific ideas about the conversion of energy to solve this design problem. © 2016 Project Lead The Way, Inc.

Module 3- Input/Output: Computer Systems

In this exploration of how computers work, students are encouraged to make analogies between the parts of the human body and parts that make up a computer. Students investigate reaction time as a measure of nervous system function. After Mylo suffers a concussion, his friends become interested in how to diagnose concussions and create a reaction-time computer program to assess a baseline before a concussion occurs. Students apply what they have learned to build their own reaction-time measurement devices on tablets. This module has strong connections to the fourth grade Human Brain module. © 2016 Project Lead The Way, Inc.
