Lang, Á., Bérczi, Sz., Hudoba Gy. and the Hunveyor-Husar Team: Measuring environmental physics and chemistry by educational Hunveyor and Husar space probe models Szaniszló Bérczi Eötvös University, Institute of physics, Department of Materials Physics, Cosmic Materials Space Research Group Teaching Physics Innovatively, Budapest, 2015, aug 17.
Introduction Interesting physics: more complex description of the processes of the environment. Our proposal: complexity should be build in the teaching program. Complexity: formulated in various ways. Should be introduced to education from simple descriptions of processes through the gradually increasing superposition of the known processes as components of the complex description. Teaching Physics Innovatively, Budapest, 2015, aug 17.
Two disciplinary sources Two disciplines with essential complexity: Environmental science Space science. We learn from them. First step: form groups of the processes they apply. Teaching Physics Innovatively, Budapest, 2015, aug 17.
Grouping of the processes Both environmental and space science propose groupings: processes run parallel. Environmental science: processes are streams. In Space probe: processes are measuring technologies. Teaching Physics Innovatively, Budapest, 2015, aug 17.
Rooks on the chesstable Two requests are unified. The form of it: a relation table. Relation table = a chesstable with rooks for each column and row. Two sets of rooks form two subsystem corresponding to the two cardinal actors of the environmental studies natural streams and technologies Teaching Physics Innovatively, Budapest, 2015, aug 17.
Processes for a town Consider a town: Natural streams to be defended are: air, water, ground, heat, etc. streams. Technologies which may destroy environmental streams: the producing and various other technologies of the town. They form a woven system, Columns correspond to the natural streams, Rows correspond to technologies . Teaching Physics Innovatively, Budapest, 2015, aug 17.
Processes for a space probe Replace town by space probe to be landing on the Moon. Task is the same, but One great difference. Producing technologies are replaced by measuring technologies Plus space probe is a miniaturized instrument complex. Teaching Physics Innovatively, Budapest, 2015, aug 17.
Surveyor - Hunveyor In the matrix arrangement the operations of the procedure of technologies are groupped into one box of the matrix, where technology row crosses the column of natural water stream. All boxes are measurements. Measurement is an interaction between a natural stream and a measuring technology. Teaching Physics Innovatively, Budapest, 2015, aug 17.

pH measuring experiment Two arms and a pump on the rover both from LEGO elements. On the first arm is the wireless camera (it can rotate around 360°) Second arm: to stretch and Front: ultrasonic sensor place the indicator ribbon to (obstacles) the surface and move it along Upper arm). a distance to contact with the A camera (right up) wet soil. Arm moves indicator ribbon The role of the pump was to (rolled). Arm is contacting pour water on the soil the wet surface soil. surface. Camera observes changes of indicator ribbon colour.

Optical-Chemistry Experiment The main tasks: Move and fix the lens so that the plane of the lens should be perpendicular to the axis of the incident solar light. Also task to focus of the lens so that the ray should reach the soil exactly. (operated at any incidence position). We used to this task 3 motors. 2 motors moves the lens around horizontal axes, and the third one around a vertical one. Husar-5 instruments built from LEGO elements Motors and controlls by the NXT “brain” driven by LEGO Mindstorms system. LEGO set contains a light-sensor, but too heavy for the experiment We used a light one photoresistor, and its signal was introduced into the NXT. Teaching Physics Innovatively, Budapest, 2015, aug 17.
Husar-5 soil optical + chemistry measurements Movement: One motor moves the arm along an arc from the horizontal about 40-45°-degrees up and down. The lens can be rotated around its symmetry axis. Basic position right on figure, ( 0° angle) than the computer program moves it from - 90° to +90° position. Teaching Physics Innovatively, Budapest, 2015, aug 17.

Summary Summary: Complexitiy should give a more realistic overview of the processes around us. Complexity is a source of both joy and innovative teaching of physics. Complexity of a space probe and its construction should give new form of teaching physics: measurements, processes, technologies, informatics. Teaching Physics Innovatively, Budapest, 2015, aug 17.
