It covers the entire 9th grade physics curriculum in the area of heat and electricity. The sets of tests are the same for the practical work in both subjects, as they are interlinked. However, the teaching materials are in two different parts.
The thermodynamics course takes a slightly unconventional approach to the topics. Firstly, there is the overarching theme of how to keep a house at a comfortable temperature with minimal cost in terms of energy and money.
Secondly, we provide students with ‘crossovers’ between textbook knowledge and real-life problems in an appropriate format. For example, a simple calculator can help you work out how much petrol you put in your car’s tank will expand in winter if it gets hot in summer. To do this, the student has to look up the petrol density in a spreadsheet and enter the input data needed for the calculation.
Finally, the computer simulations used in the textbook are so realistic that it is possible to “discover” the laws of nature by studying them, and to analyse situations that are difficult to reproduce in experiments.
The courses tools in the toolkit are designed to build realistic heating and cooling systems. For example, students can learn how heat stored in the ground in summer can be used for heating in winter. There is also the option of freezing juice into a stick of candy, or pumping heat from a colder to a warmer body using electricity.
Many of the tests in the textbook are closely related to the 9th grade electrical topics, so the two courses could be planned as an integrated whole.
The study course covers everything you need to learn and you don’t necessarily need another textbook. In addition, it contains a wealth of methodological material on both the general structure of the course and the ideas behind the specific worksheets.
Here you can see a real lesson from the thermodynamics course. This view is primarily intended for the teacher, so methodological comments on the different parts of the lesson are included.
Praktikal’s lessons consist of worksheets. This is the part that is seen by the student. The worksheets have a variety of content – tests, simulations, questions, exercises, quizzes, etc.
Lessons are grouped into five themes, which form a logically structured learning path.
The study kit is divided into 21 lessons.
The electricity course is divided into four topics: electrostatics, circuits, energy and power, and magnetic phenomena. In electrostatics, we use traditional experiments, but we have put together a set of tools from the best materials available, ready to use for easy experimentation.
For the study of current circuits, we offer a three-bulb model board, which has, in practice, proven to be a better option than kits with separate bulb sockets. Accessories that are used in the kits of other courses (e.g. heaters and motors) can also be connected to the circuits. In addition to standard incandescent lamps, the kit also includes an LED lamp with the same filament and one higher rated filament lamp, which offers exciting comparison possibilities for students.
To study magnetic phenomena and the magnetic effects of electric currents, the kit includes semi- and framed neodymium magnets. For example, students can build a simple electric motor, but the procedure is made simpler and more didactically useful with the included materials. The collection also includes materials on energy consumption and conservation. For example, you can find out how much energy is lost in the power supply in the test kit.

In addition to traditional test tools, such as calorimeters, thermometers, scales and rods of different materials, the experimental kit places particular emphasis on the most important practical output of thermal education – heating and cooling. The test kit includes a model of a building that can be used to play out real summer and winter temperature problems. The temperature of the “room” can be measured from the floor and the ceiling, and it can be heated using different types of heat transfer. The important role of convection becomes clear. A heat pump is also included in the test kit, which can be used to pump heat from a warm body to a colder one, for example cooling water until it freezes.
Praktikal’s set of extensions allows you to make almost any classroom suitable for practical work requiring electricity. It is also suitable for other activities where it is necessary to provide convenient and safe access to electricity for students’ desks. Each extension has five plugs that can be clipped to a standard school desk. The plug connects to the mains supply via a leakage circuit breaker.
PS! If necessary, extension kits can be added to the course kits.
