Circuits

Electrical engineering is omnipresent in the pupils' world of experience. The experiments in the case help them gain insights into the use of electricity to generate light, heat and movement. These three possible uses are reproduced in simple experiments and then transferred to the environment.
The children learn that electricity can only develop its effect when it "flows in a circle" through conductive materials - and that technically stable connections are necessary for this. The simple materials in the case in traditional connection technology make these elementary relationships transparent and manageable.

The following topics are covered:

• Open and closed circuits
• Series and parallel connection
• Conductive and non-conductive materials
• Electric current hazards
• The path of household electricity

From Batt-Man to the trembling roller coaster with the buttonhole lamp to the robot game.

• 33 stations with suitable templates
• Material for 15 groups

Materials for 15 work groups.

Thermometers teaching unit Children learn how to make a thermometer by themselves, how to use it and how to determine freezing and boiling points of water on a thermometer without scale. This way they learn the basic terminology and theories of heat and thermal expansion. Evaporation and condensation teaching unit Children learn to understand the water cycle by finding out what happens when a liquid is converted into a gas and that a gas can be converted back into a liquid.

Thermometers teaching unit • Heating and cooling water • Heating and cooling methylated spirits • How does a thermometer function? • What is a thermometer for? • The Celsius scale • Taking temperature measurements and reading exercises Evaporation and condensation teaching unit • Converting a liquid into a gas • Water evaporates, vaporizes too • Vaporizing liquids are cooling • Can a gas be re-converted into a liquid? • What happens when steam cools down? • The water cycle • How water particles unite

Can light go around the corner? Are there coloured shadows? Why is it dark at night? Light and shadow, colour and reflection are optical phenomenons, that fascinate children. Experiments will help them to understand the natural scientific facts behind the phenomenon. The field of vision, the structure of the human eye and other secrets become comprehensible. All experiments tie in with the experiences of the children. In a playful way they will find out the laws of reflection, the composition of light and optical illusions. Playing with shadows will lead to surprising discoveries.

Light and vision • Human eye • Field of vision • Seeing in the dark • Optical illusions Reflections • Strange multiplication • Flame in water • Curved mirrors • Flexible mirrors Shadow • Shadow • Shadow play • Coloured shadows • Day and night Colours • Colours of the rainbow • Colours in the light.

Materials for up to 24 workstations.

Lessons about magnets Children learn about the properties of magnets. Half of the bar magnets in the kit do not have pole marks so that the children learn to determine north and south poles for themselves. Lessons about the magnetic compass Experiments with suspended or floating magnets lead to an understanding of how compasses work. Children also learn to assemble their own compasses and to use them properly.

Magnet – Iron • The big material test • A ‘metal exhibition’ • Uncle Scrooge’s fishing game • The big iron test • Rusty bike? • Using paper clips to find magnets Magnetic force • The swinging paper clip • The walking scarecrow • The dancing snake • The floating paper clip Pro and Contra • The bewitched second magnet • Magnets in a tube • The bewitched garage • The submarine trip Mixed information about magnets • How people discovered magnets • The biggest magnet we know • The teacher’s magnet exhibition • Make your own magnets • Magnets without marked north poles Hanging, floating and turning magnets • Floating magnets • Hanging magnets • Making compasses, using hanging and floating magnets • Floating compass needles • ‘Real’ compass.

Materials for up to 25 workstations.

This kit can be used in lessons covering physical and technical subjects as well as music and languages. The kit is especially suitable for learning in groups at specific workstations but can be used for any other type of lesson too. With the help of four CDs the children learn to classify sounds and noises and to identify and name them. They also learn to distinguish similar noises. Needed in addition: One or two CD-players.

Hearing, recognising and naming sounds • Assigning pictures to noises • Recognising and naming sounds • Pairs of sounds • Miming a sound story Hearing, seeing and feeling vibrations • Secret tickling • A tuning fork in water • Tuning fork ball games • Singing needles and steel strips Making high and low tones • The rubber band zither • Building a xylophone • A panpipe • A mbira (thumb piano) Amplifying and damping sound • Loud or quiet? • The mysterious body • A sound beaker • A ‘cackle box’ Transmitting sound • Why do we have two ears? • Along the string and into your ear • A string telephone • Sound travels • The magic finger • A stethoscope • Hearing through plastic tubes Conclusion • Accompanying a story with suitable noises

In plastic box with handle.

This case contains an easy-to-use collection of measuring devices that can be used in primary school wherever temperature, weight and length need to be learned and measured. It has proven itself in physical education in physical and biological studies, but also in mathematics lessons.

The pupils can acquire elementary and contemporary knowledge about measurement conventions as well as the functioning and use of measuring devices. In a "measurement triathlon" they demonstrate that they can select the right measuring device, use it properly and record the results.
