Du willst wissen, ... wie man Wasserstoff herstellt? ... was eine Elektrolyse ist? ... wie man Eisen oder Zucker nachweist? Junge Chemiker erforschen bei 250 anschaulichen Experimenten die Reaktionen chemischer Stoffe. Und beim Erhitzen mit dem Spiritusbrenner enthüllen die Stoffe plötzlich überraschende und neue Eigenschaften. Das ausführliche, reich bebilderte Anleitungsbuch vermittelt chemische Arbeitsmethoden und leitet zum eigenständigen Experimentieren an: Verbindungen werden in ihre Bestandteile zerlegt oder neue Stoffe hergestellt. So wird mit abwechslungsreichen Versuchen allmählich die chemische Formelsprache anschaulich eingeführt. Das Versuchsprogramm führt in die anorganische, die organische und die Elektrochemie ein und weckt den kindlichen Forschergeist.Achtung! Für Kinder unter 3 Jahren nicht geeignet. Erstickungsgefahr, da kleine Teile verschluckt oder eingeatmet werden können.

Value for your money
Style: AVR-X2800H
I am loving the sound quality while listening to music as well as watching movies. I am running a 5.2.2 surround sound which is a step up from my sound bar and I am loving it. This receive has tons of features. Apart from the sound quality, I love the fact that I can set my power on volume and a volume limit.

More like a 7.1.2 not 7.2
Style: AVR-X2800H
Looks and feel brand new, set up is easy especially if you have used Denon before. I needed to upgrade my old system to get the 8k signal for a new TV i bought.
The only issue I've had is its listed as 7.2, but its more of 7.1.2. You can connect 7 speakers and adjust each individually, you can connect 2 subs but they both receive a split signal and can not be individually adjusted in the receiver.
A little misleading, but still a great system.
