Students will also create their own IoT device by connecting a LED 101 light to their CloudProfessor and control it via the Internet. Learning Objectives Define what is meant by the Internet of Things (IoT). Know that a computer or smartphone can control other devices over a network. Understand the advantages and disadvantages of living in a smart world. Learning Expectations (how learning / progress will be demonstrated) All Design a smart home which utilises the Internet of Things (IoT). Most Use a simple program to control an LED light across a network. Some Explain the benefit and drawbacks of living in a smart world. Curriculum Links (Computing PoS) Understands that people interact with computers. Knows common uses of information technology beyond the classroom. (GE) Recognises that a range of digital devices can be considered a computer. (AB) (GE) Knows that computers collect data from various input devices, including sensors and application software. (AB) Computational Thinking Concepts: AB = Abstraction; DE = Decomposition; AL = Algorithmic Thinking; EV = Evaluation; GE = Generalisation. 1 Introductory Lesson 2

2 2 Teacher s guide Part 1 Background You may have heard of the term Internet of Things (or IoT for short). But what does the Internet of Things actually mean and what impact will it have on our lives? Whether you use a fitness monitor, own a smart TV, have a voice-controlled intelligent personal assistant (Amazon echo), or your home is controlled by smart active heating (Hive / Nest), chances are, the Internet of Things is already part of your life. Put simply, the Internet of Things allows us to connect a wide variety of electronic devices to the Internet from heating and lighting to cars and fridges (pretty much any electronic device you can think of) and has the potential to transform not only our lives but also how we work from improving our health to optimising our energy consumption. It is estimated that by 2020 there will be 50 billion things connected to the internet. IoT and STEM So, what has the Internet of Things have to do with STEM? In science, we already use sensors and data logging equipment to collect data, such as temperature and light, and use this data to make predictions. In computing, we learn about how the Internet works, investigate automated systems in the wider world and explore event-driven programming. In maths we learn how to interpret data and present it in a meaningful way, without which, the IoT would just be a mass of data that tells us very little.

3 2 Teacher s guide Part 2 Overview In this lesson, students will design their own Smart home which utilises the Internet of Things (IoT). Students will also create their own IoT device by connecting a LED 101 light to their CloudProfessor and control it via the Internet. Starter Instruct students to power up and connect their CloudProfessor. Hand out the step-by-step guide and ask students to follow the instructions and observe what happens. Activity 1 Ask students what they think is meant by the term Internet of Things (IoT). Draw out answers such as smart homes, smartphone controlled devices, wearable technology etc. Explain to students that by 2020 it is estimated that there will be 50 billion things connected to the internet, from heating and lighting to cars and fridges. Tell students that we call this the Internet of Things or IoT for short. Arrange the class into small groups. Provide each group with two of the device cards (see attached worksheet) chosen at random. Challenge the students to think of a scenario where each device could be connected to the Internet of Things in order to solve an every day problem, for example: A connected wardrobe that checks the day s weather forecast and suggests appropriate clothes to wear or a smart refrigerator with finger print or facial recognition that stops you from snacking in-between meal times. Activity 2 Inform students that they are going to design their own smart home which utilises the Internet of Things. Hand out the smart hone worksheet and ask students to follow the instructions. Explain to students that they must write down or draw in each room the objects which could be controlled with an app on a smart phone e.g. lights, heating etc. Tell students that they can also design the icons for their apps using the smart phone template provided. Plenary Students share their IoT innovations with the rest of the class and explain how it works. 3 Introductory Lesson 2

4 3 Step-by-step instructions (Student handout) 1. Connect the power of CloudProfessor then press and hold the power button for two seconds; it will turn on and the power indicator will light up. 2. Insert the LED 101 light set into the USB 3.0 slot on the CloudProfessor. 3. When the CloudProfessor detects the LED 101 component, a notification will appear on your device; click the notification to launch the open the CPF LED101 App, and then select CPF LED101 Blockly Press the execute button to enter the control user interface (UI). The UI can be used to control and turn the white LED light and the three-coloured red, green, blue LED light on or off. 4 Execute button Toggle switch 5 CPF LED101 app Control user interface (UI) 5. Press the toggle switch for the White LED and watch the LED light up. Do the same for R, G and B and observe what happens. 4 Introductory Lesson 2

Challenge the students to think of a scenario where each device could be connected to the Internet of Things in order to solve an every day problem. 5 Introductory Lesson 2

6 Instructions: Use the template below to create your own smart home. Write down or draw in each room the objects which could be controlled with an app on your smart phone e.g. lights, heating etc. Draw the icon for each app on your smart phone (right). Smart Phone Apps Did you know? Once set up, your smart home appliance with CloudProfessor can be remotely controlled from anywhere that has Internet access! 5 Smart home worksheet 6 Introductory Lesson 2

7 6 Extension Students to design a piece of wearable technology. This could be something realistic such as a smart glove which has the ability to control things around the home or something futuristic such as a suit covered with sensors which can react / change in response to its environment. Alternatively, students could attach the 101 LED component to their smart home design and control it with the CloudProfessor. 7 Differentiation To support students, provide step by step guides. To stretch students, ask them to design their smart home on a computer using a suitable program of their choice. 8 Homework Students to research the advantages and disadvantages of living in a smart world and write an argument either for or against the Internet of Things (IoT). 9 Links The Internet of Things (BBC Bitesize): Living in a smart world (OCR ibytes): The Internet of Things explained simply: Disclaimer: Use these sites at your own risk.
