Every age bracket and educational group has specific needs and different learning methods. To ensure a maximal learning success for every user, the leXsolar-product families are divided into various product lines.
leXsolar Small Series
leXsolar Medium Series
Kindergarten and Elementary School
Middle school Junior high school
Children have a natural drive to research and want to discover the world around them. At the same time, the cornerstone for school education is set in kindergarten and elementary school. Connect those two aspects and let children discover the topic of renewable energies in the form of playful experiments. As a result, children are able to develop early awareness for renewable energies and learn how they function.
In secondary education, knowledge developed from elementary school is deepened and consolidated: initially it is experience-oriented working and later becomes more and more scientific. Both can be achieved with the products of the leXsolar Medium line. With the aid of experienceoriented experiments, inspire your students and increase their focus. At the same time, students are motivated for the following scientific experiments.
8
Designed for the small yet big in application – these are the products of the leXsolar Small series. Simple experiments and playful learning take priority which is why the experiments are all self-explanatory. In the enclosed brochures you can find background information which is easily comprehensible even for those without a scientific background. The products can be used by the hands of children as well as adults, and at the same time they are robust so they can withstand the eagerness of experimentation.
understanding new energies
leXsolar Large Series Secondary school
Compact in size, inexpensive in acquisition and comprehensive in the fields of application, the leXsolar Medium series offers you a mixture of simple qualitative and challenging quantitative experiments. The provided instruction manual contains extensive background information and operating instructions. The products of the leXsolar Medium line are delivered in sturdy plastic boxes. Common school supplementary equipment like measuring devices and cables are not included.
High Schools prepare for a university education as well as an engineering education. To meet these requirements you can carry out practicallyoriented experiments regarding scientific elements of the renewable energy technologies. A special feature of the leXsolar Large series is the modular design to extend the fields of application to further grades or topics.
leXsolar Ready-to-go Series For flexible users
The leXsolar Large line is adapted to the latest curricula and is ideally suited for the application within scientific teaching. For this reason, leXsolar-PV Large has been awarded with the Worlddidac Award. The products allow mainly quantitative student-based experiments and deal especially with the physical basics of particular renewable energy technologies. In school, already existent auxiliary equipment such as multimeters, cables or similar are not included.
„Ready to go“ – the name says it all. Everything is enclosed in a robust aluminum case and ready for use at any time – in or even out of school. For this reason all necessary accessories, such as measurement devices and cables, are included. Like the leXsolar Large series, the Ready-to-go- series offers a wide area of different experiments – from simple entrylevel experiments to more challenging advanced experiments. All in one, immediately and everywhere, these are the keywords, which best describe the Ready-to-go series. It is the most flexible solution for all users: schools, industry or extra-curricular clubs.
