Through four lesson and four activities, students are introduced to the logic behind programming. Starting with very basic commands, they develop programming skills while they create and test programs using LEGO MINDSTORMS(TM) NXT robots. Students apply new programming tools move blocks, wait blocks, loops and switches in order to better navigate robots through mazes. Through programming challenges, they become familiar with the steps of the engineering design process. The unit is designed to be motivational for student learning, so they view programming as a fun activity. This unit is the third in a series. PowerPoint® presentations, quizzes and worksheets are provided throughout the unit.

Students are introduced to the basic concepts of computer programs, algorithms and programming. Using a few blindfolds and a simple taped floor maze exercise, students come to understand that computers rely completely upon instructions given in programs and thus programs must be comprehensive and thorough. Then students learn to program using the LEGO MINDSTORMS(TM) NXT software. They create and test basic programs, first using just the LEGO NXT intelligent brick, and then using basic movement commands with the LEGO NXT software on computers. A detailed PowerPoint® presentation, plus a worksheet and pre/post quizzes are provided.

The purpose of this activity is to demonstrate how drag affects falling objects. Students will make a variety of shapes out of paper and see how size and shape affects the speed with which their paper shapes fall.

Students learn about friction and drag two different forces that convert energy of motion to heat. Both forces can act on a moving object and decrease its velocity. Students learn examples of friction and drag, and suggest ways to reduce the impact of these forces. The equation that governs common frictional forces is introduced, and during a hands-on activity, students experimentally measure a coefficient of friction.

Students further their understanding of the engineering design process while combining mechanical engineering and bioengineering to create assistive devices. During this extended activity (seven class periods), students are given a fictional client statement and required to follow the steps of the engineering design process (EDP) to design a new wristwatch face for a visually impaired student at their school. Student groups share their designs with the class through design presentations. A successful design meets all of the student-generated design requirements, including the development of a new method of representing time that does not require the sense of sight. Through this activity, students design, construct and iterate classroom prototypes of their watch designs.

Students will have to solve the real world problem of locker smell leakage by building an air filter that will cover the vents on the top of a locker. This project goes well with a curriculum on the particle nature of gases and phase changes.

Students investigate passive solar building design with a focus on heating. Insulation, window placement, thermal mass, surface colors, and site orientation are addressed in the background materials and design preparation. Students test their projects for thermal gains and losses during a simulated day and night then compare designs with other teams for suggestions for improvements.

A park ranger needs to build a zipline to drop food supplies to her mentor park ranger at the bottom of a gorge. Unfortunately, she does not have the instructions to build the zipline according to the proper specifications. Without directions, she is unsure of the correct angles to attach her zipline to each tree. Additionally, she needs to figure out how to open the chute to drop the food supplies. Challenge: Create a zip line that will release from her bucket (paper cup) the food supplies (represented by a marble) onto the target (placed 5/8 of the way down the zipline) before the gear reaches the opposite end of the zip line.
