Introduction

LEGO® Education is pleased to bring you the 2009594 Activity Pack for the 9594 Green City Challenge Set. This activity pack is ideal as a step-by-step introduction to robotics in the classroom and as preparation for robotics competitions.

The Green City Challenge SetThe set consists of six Training Mats, two Challenge Mats, Dual Lock tape and 1,365 LEGO elements for building the twelve Challenge models. The Training Mats are the learning areas where students can develop their programming skills as described in the Training Activities. The Challenge Mats combined with the Challenge models provide an engaging and motivating platform for students to creatively apply and further develop their programming and problem-solving skills.

Activity Pack for the Green City Challenge SetStarter GuideThe Starter Guide is a step-by-step explanation of the essential features of the LEGO MINDSTORMS® NXT Software. It is a good starting point and provides you with the knowledge of the software you and your students need to get started on the Training Activities.

Training ActivitiesThe seven structured and easy-to-follow Training Activities are intended to heighten students’ robotics skills in an enjoyable and challenging way. The Training Activities focus on hands-on building, programming, experimenting and problem-solving.

Throughout the comprehensive Teacher’s Notes you will find everything needed for easy implementation including explanations, hints, programs, and ideas for further extensions of the activities.

The Training Activities follow LEGO Education’s 4C approach: Connect, Construct,

Contemplate and Continue. Each activity provides text and visuals to help students Connect to the purpose of the activity. Then the students will Construct their models, engaging both hands and minds. Next the Contemplate phase will encourage the students to carry out more activities to test and adapt their programs to specific tasks, and to reflect on what they have done. Finally they will progress to the more open-ended Continue phase, focusing on particular programming features or improving and optimizing their robots’ performance.

Each Training Activity comes with a Student Worksheet. The Student Worksheets support the students’ progression through the activities as well as encouraging them to reflect on their programming.


Starter Guide

If you are taking your first steps in robotics, don’t worry: this section will explain the essentials that you will need to know before starting on the Training Activities and navigating the software.

In the Training Activities you will find a step-by-step guide to many of the common programming features which will allow you to progress through the learning process of robotics at your own rhythm. Using the tutorials that are in the software you will be guided by Challenge Briefs, Building Guides and Programming Guides. Building on the tutorial, the Training Activities then provide further challenges for you so that you learn to make alterations and create your own programs to solve specific problems and missions.

Have fun!

Introduction


The Green City ChallengeThe Green City Challenge allows the students to apply and adapt all their programming and problem-solving skills by making their robots solve Challenges related to renewable energy.

The Green City Challenge sets the scene for the Challenges the students have to solve. For easy differentiation there are three levels of the Green City Challenge, from the introductory Level 1 to the more advanced Level 3. For each Challenge the students are given a simple set of rules, a mission and a points system.

On Level 1, students will solve the Challenges by controlling the movements of their robots.

On Level 2, students will have the possibility of using sensors in their solutions to the Challenges.

On Level 3, students are required to use sensors to solve some of the Challenges.

All levels of the Green City Challenge are open to further possibilities for differentiation, allowing you to adjust each Challenge to just the right level of difficulty for your students. You will find some suggestions on the “Varying the Green City Challenge” page, but there are many more possibilities.

At each level the score sheets make it easy to determine how many points each team has scored.

Solution GuideThe Solution Guides provides you with a complete solution to the Green City Challenge. For each mission you will find a simple guide to the robot and program that can solve the mission and an indication of the starting position from which to launch the mission.

First, you need to follow the Building Instructions for the robot and the different extensions to the robot. Our solution robot is always based on the standard robot that is also used for the Training Activities.

Then, you need to download the program to the NXT. Due to variations in friction, light conditions, battery level and the condition of the LEGO® components, it must be expected that it will be necessary to make adjustments to the programs.

Next, place your robot on one of the two pre-marked starting positions numbered 1 and 2 and launch your mission.

You may choose to keep the Solution Guide as a reference base, use it as inspirational material or share it with your students.

Introduction


Research ProjectThe Research Project is the students’ opportunity to investigate what makes a Green City and how they can help make the world greener.

The students are challenged to initiate their own Research Project and to come up with practical solutions for making their school, local community, town, city or country into a Green City. While conducting their research the students need to carefully consider the value of each piece of information and of the source that it comes from.

Once the students have conducted their research and developed their solutions, they are asked to share them with their classmates.

Building InstructionsThe set includes Building Instructions for all the twelve Green City Challenge models. Also included are Building Instructions for robot extensions that allow you to build robots that can solve each Green City Challenge.

Classroom Management TipsHow to get startedThere are many ways of using the Green City Challenge Set. Most will start with the Training Activities, progress to the Green City Challenge and end with the Research Project.

If you choose to start with the Training Activities it can be a good idea to use a lesson to build the complete robot with all its extensions, following the Building Instructions provided in the 9797 LEGO® MINDSTORMS® Education Base Set.

Then print and hand out the Student Worksheets and let the students progress through the activities at their own pace, or go through each activity and discuss the different approaches to the activities and how the robotics features involved could be applied to solve problems in the real world.

Another approach would be to start with the Green City Challenge and afterwards use the Training Activities for reference and inspiration.

If you choose to start with the Green City Challenge, start by letting the students build all the Challenge models. Printing the 1:1 measurement sheet can be helpful. Spend some time examining the functionality of the models, as this can lead into a good discussion of possible ways of solving the individual missions.

Then print the Green City Challenge, Rules of The Green City Challenge and the Mission Brief for the level of your choice. Let your students design their robots, program them, experiment and come up with their own innovative solutions to the Green City Challenge.

Use the Solution Guides as you see fit, but always encourage the students to come up with their own solutions. The Solution Guide may present a simple way of solving the Green City Challenge, but not the only way. Remember that all the programs we supply will need you to make adjustments, due to variations in robot build and light conditions.


Green City Research Project

You can read these words, because there is light around you!Maybe it’s the sunlight that comes in through the window. The sun, a renewable energy source, is essential for all forms of life on Earth.Maybe it’s light coming from lamps in your classroom. In that case, you and your classmates are most likely using energy derived from a non-renewable energy source, in the form of electricity generated by burning coal, oil or gas.

A Green City is a city where renewable energy sources are used more than non-renewable energies and where environmental concerns are shared by all.Also, in a Green City subjects such as• developing renewable energy sources• saving energy• reducing pollution• recycling material• managing trash disposal and• accessing drinkable waterare considered when taking important decisions.

Introduction


Handle the mats with careIf handled with care the mats will last a long time.Remember:• Roll the mats up and return them to the box for storage• Mats will tend to curl up after a long period rolled up in storage. Placing a heavy

object at each corner can overcome this problem. Do not try to roll up the mats the opposite way, as this can damage them

• Pay special attention to the edges of the mats, as they can easily be damaged• Be careful when removing the Green City Challenge models from the Challenge Mat• Place the mats on a table rather than the floor• Avoid stepping on the mats• Keep all foods and liquids away from the mats• Use one Challenge Mat when getting ready for the Challenge and save the other

for the day of the Challenge• Be careful when handling the mats, as paper can cut the skin.

Reduce building timeSplit up the Building Instructions for the Green City Challenge models Green City and Dam into two. Having two groups building each model simultaneously and then combining their models can help reduce the total building time.

Store the Challenge modelsAnother good tip for saving time is not to take your Green City Challenge models apart after use. Wrapping the models in cloth, paper or plastic wrapping can help preserve them.

Dual Lock tapeYou might want to handle the placement of the Dual Lock tape yourself, as this can be tricky. Once you have placed the Dual Lock tape on the mats you should only remove it again with great care, as this can damage the mats, and it is advisable to leave it in place if possible.

How much time do I need?The set is designed for 45 hours of tuition, but features extension ideas for many more hours of learning. Double lessons are ideal for students working on both the Green City Challenge and the Training Activities if they are to design, program and test in depth.

We hope you enjoy working with the Green City Challenge.LEGO® Education
