The context method

We have been one of the first worldwide to publish textbooks in natural sciences using the „context method“.

The context method facilitates a strongly pupil-oriented type of learning which also ensures the acquisition of structured basic knowledge. The context units establish a connection with everyday themes and practical scientific work, while the foundation units provide summaries and systematic presentations of what has been learned.

L Floating and Sinking Floating and Sinking

The pupils can discover the assumed loss of weight when a body is suspended in water.

Included in delivery: Manual “Science Kit SINKING AND FLOATING” The kit contains a complete collection of materials to work on the topic of floating and sinking on the level of 7-9 years pupils.

Ships are floating and sometimes they are sinking. The ships in the experiments are formed from two different kinds of plasticine, one lighter than water and the other heavier than water. The concept favours work in pairs to strengthen the competence of

the pupils. They learn that the heavy plasticine sinks unless they shape it in a buoyant form.

The plasticine can be clearly distinguished by their colours.

The kit comes also with a set of different materials, ships are made from nowadays: wood, steel, aluminium and different plastics.

All phenomena are examined seperately in comprehensible experiments: The carrying capacity of ships, the displacement of a body suspended in water, the buoyancy and the surface tension of water.

The manual contains 14 experiment descriptions which can be carried out with the materials from the box.

Air R P

Air We are constantly breathing air.

The air pressure weighs on us. Air is something concrete and material. Most young students don’t know this.

Therefore many of the characteristics of the air that seem to be self-evident are questioned so that the students can identify them.

Lots of simple experiments can be carried out by the students.

The teachers can give demonstrations using a hot air balloon and a model of a rocket.

S

• Air can displace water from a container just as water can displace air.

• Air can be contained within other substances.

Air exerts a force: • Air can be compressed and will expand again.

• The force of compressed air can be used to lift an object.

• Force of an air current can be used to propel an object.

• Heated air expands, becomes lighter, and will therefore rise.

• Air acts as a resistant force against bodies which are moving.

Important learning aims: Air occupies space: • Containers which appear empty contain air.

• The space in a container which is occupied by air cannot be taken up by another body at the same time.

Air pollution and effects: • Dirt particles are present in the air.

Recycled Paper R P

Recycled Paper The protection of the environment is a topic which is becoming increasingly important.

Experience has shown making paper from wastepaper to be a particularly useful teaching method.

L Tellurium N Tellurium

Tellurium N – The innovation in Tellurium design The Tellurium N was designed by Prof. Dr. J. Newig, Kiel in cooperation with Cornelsen Experimenta.

The particular innovations are the use of a Fresnel lens to produce an extra bright and parallel light beam which illuminates the earth globe completely, the focussing of a light point on the globe to demonstrate the apparent movement of the sun between the tropics and the use of a horizon disc with shadow-pin figure to show the position of the sun by the shadow fall.

Teacher’s manual: The manual describes lesson elements in detail for the following 13 topics: • The earth as a gyroscope in space • Day and night • Hours • Polar day and polar night • Tropics • Seasons • Day- and night lengths at various latitudes

• Daytimes • Lunar phases • Eclipses • Tides • Eratosthenes earth circumference experiment • Geostationary satellite

The horizon disc with shadow pin figure: With the horizontal disc, which can be put on the globe at any place, the changing situations of illumination on earth can be explained easily comprehensible with the shadow pin figure.

The Fresnel lens:

The power supply: The power for the 12 V/20 W quartz iodine lamp in the “sun” is supplied by a mains plug unit which is connected with the Tellurium by a cable with jack plug.

A Fresnel lens with a short focal length provides a directed, parallel light with the result that a full half of the globe is illuminated and the shadow line (day and night) corresponds with the nature. Formerly designed Telluriums are not able to show it like this.

Tellurium N R P

S

The three positions of the Fresnel lens: The Fresnel lens can be put on the Tellurium arm at three positions: Day and night, seasons At this position the globe is fully illuminated and the shadow line is clearly visible.

Tropics (sun-point) Here the lens focuses a small light point with a “hale” on the centre of the globe.

When the earth is turned around the sun the light point moves across the equator between the northern and southern tropic.

Lunar phases At this lens position the moon will especially be illuminated. When the moon is turned around the earth by hand the lunar phases and the eclipses can clearly be demonstrated.

The large earth globe with telescopic rod:

The moon on a telescopic support rod:

The shadow line and other details are clearly visible on the large globe (15 cm dia.) even from a long distance. With the telescopic pole rod (33 cm long) the position of the earth with its direction of the earth axis to a fixed point in space (the North Star) can be demonstrated convincingly.

The moon can be moved around the earth by hand and adjusted in height to demonstrate lunar phases and eclipses.

The date disc and the date pointer:

Cradle Globe for students practise

The earth globe is mounted on a large date pointer which moves around the date disc when the Tellurium arm is turned around the sun. Corresponding to the date pointer position the earth axis is turned towards or away from the sun (seasons). The dates of the summer- and winter solstice as well as the equinoxes are especially marked on the date disc.

The cradle globe is especially suited for lessons in combination with the Tellurium N to measure distances and time differences on earth in small groups of students.

The cradle globe can be turned in all directions and is suspended in a clear acrylic support with distance and time scale at the height of the equator. The globe is inscribable with a water soluble felt tip.

Including felt tip and wipe.

Dimensions: Base: 180 mm Ø x 90 mm height Globe: 150 mm Ø

The satellite rod: To demonstrate the position and movement of a geostationary satellite a rod with a „satellite“ on the top can be set on the shadow pin figure of the horizon disc.

Design The components of the kits are solid and specially designed for students.

All elements are tested and can be used for several experiments, so that the number of parts could be limited to an economical quantity.

All components can be supplied as spare parts.

A high quality aluminium rail profile is used as stand material to support the experiment set ups in mechanics, heat and optics.

Special clamp sliders allow stand rods or other accessories to be mounted in a fixed or movable position on the rail.

With the multipurpose boss heads, stand rods or other parts can be fixed in all positions.

Feet plugged on the ends of the rails guarantee a stable stand of the experimental set ups.

The electric and electronic components are visibly mounted in plug in holders.

With the multipurpose circuit board they can be arranged to predefined circuits or independently.

Contacts and switches can be assembled out of the contained components.

Molecules With the components contained in the molecule construction boxes molecular models can be assembled representing practically all the important compounds of chemistry that are dealt with in secondary schools. The positions of the atomic nuclei and the bonds between the atoms are shown particularly clearly by these structural (rod-and sphere) models. The molecular models are assembled simply by linking up the models of the atoms using the connecting rods. The rods are flexible, so that they can also be used to show multiple bonds.

The colour coding of the different atoms follows international conventions.
