3How to work with this e-book
Table of Contents
You will find texts and tasks in this ebook, with white boxes for student answers, pictures, and videos. Of course, you might as well take the teachers' version and just delete parts of the answers in order to give more assistance and to have a closer guidance through the tool.
If needed, BookCreator features a reading-out function, so that students can easily listen to the pronunciation of words they haven't learnt yet.
Most of the rather tricky English words will have a translation at the bottom of the page, however there is a comprehensive vocabulary list at the end of the book.
1. Great Colours!
2. It's getting cold here...
3. Thieves and Spies
4. Physics for your Eyes: see, shine and flow
5. Everyday Tech
6. Chemistry and Environment

Great Colours!
Research, building restoration, hunting, military and firefighting are just a few of the areas that rely on thermal imaging camera¹.
The thermograms ² also play a vital role in scientific experiments, as they give new insight to aspects of processes humans can not observe with their eyes. Go try it yourself!
• 1.1 What physical quantity³ can be depicted with a thermal imaging camera? How is this physical quantity visualised?
• 1.2 Identify which objects the thermal imaging camera can register and explain why some things can or can not be registered. To show this, insert pictures of objects taken by a thermal imaging camera and a normal camera.
• 1.3 Experiment with the thermal imaging camera and examine the colour in the thermogram. Explain the meaning of the colours depicted.
After having carried out your first experiments with the thermal imaging camera, you want to take a look at the created thermogramms (the images taken by the thermal imaging camera). You want to know what influences the objects' colouring in the thermogramm.

Experiment
Material: thermal imaging camera, water (hot, cold and room-temperature), thermos, cups (3 different colours and three transparent ones)
Preparations: Set up the camera and line up the cups.
Procedure: Develop experiments that will help you answer the questions below.

Procedure: Develop experiments that will help you answer the questions below.
• 1.4 Are there factors or properties¹ of the objects influencing the colouring in the thermogram? For example, consider factors like surface texture².
• 1.5 Is there a correlation³ between the object's visible colour and its colouring in the thermogram? Take pictures with a normal camera and a thermal camera to support your answer.
• 1.6 Open the thermal imaging camera's app and search for other colour ranges in the bottom menu bar. The settings will influence the colouring of the objects, test them.
