Notes on disposal of electrical components

None of the electrical or electronic components in this kit should be 
disposed of in the regular household trash when you have finished using 
them. Instead, they must be delivered to a collection location for the 
recycling of electrical and electronic devices. The symbol on the product, 

instructions for use, or packaging will indicate this. The materials are reusable in 
accordance with their designation. By reusing or recycling used devices, you are 
making an important contribution to the protection of the environment. Please consult 
your local authorities for the appropriate disposal location.  

NOTE!

 The additionally required items 

are highlighted in italic script in the 
individual experiments. Before starting 
the experiments, carefully read through 
everything that will be required and make 
sure to have all the materials ready.
