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.

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

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

• ther

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.

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.

The Hunveyor-Husar-Hunballon space probe model system

 Beginning of Hunveyor (1997) ... and  Husar (Hungarian University Surface Analyser

Rover) (1999) ...

 Test-table for Hunveyor (1999).  Later a Hunballon group involved.  Demonstrations by Mathematica program (by S.

Kabai) (2005).

 Plans of Hunbleweed – Ördögszekér: (roling on

its branchings) (2010).

Husar-2, -5, -9 and -11 rovers

 H-2 a, b, d,

and eHusar

 H-5 and  H-9 measure-

ments

 H-11 Spherical

rover (Hungaro- sphere)

Planetary Surface rocks: Husar-9

 Identifications of the rock

types by their textures.

 Measuring magnetic dust

transported in the winds (Mars)

 In the carpet magnetic

cubes are hidden.

 Transported dust grains

are adhered by magnets and the position of the magnetic cubes becomes visible.

Measuring the pH and triggered gases by the Husar-5 rover

 A

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

place the indicator ribbon to the surface and move it along a distance to contact with the wet soil.

 The role of the pump was to

pour water on the soil surface.

Front: ultrasonic sensor (obstacles) Upper arm). A camera (right up) Arm moves indicator ribbon (rolled). Arm is contacting the wet surface soil. Camera observes changes

• f 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.

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

• n figure, ( 0° angle) than the

computer program moves it from - 90° to +90° position.

Summary

 Summary:  Complexitiy should give a more realistic

• verview 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.
