Aufgabe 2: Mathematics
10 Punkte
A school art group mixes two colours of paint in the ratio 2:7. It plans a 180 L batch, then estimates that 15% of the mixture will be lost during transfer. The ratio applies to the mixture before and after transfer only if both colours are lost in the same proportion.
Daten und Belege
- Colour A : colour B = 2 : 7; planned batch = 180 L.
- Transfer loss = 15% of the whole batch. Assume both colours are lost uniformly.
- A learner claims that subtracting 15 L gives the usable volume and that 2/7 of it is colour A.
Calculate the original volume of each colour, the usable total volume and the usable volume of each colour. Show the ratio-unit and percentage steps with units, and check that both pairs of volumes add to their respective totals.
Vertiefung: Explain both errors in the learner's claim and what would change if the two colours were lost at different rates.
Bewertungskriterien und Lösungshinweise
- 2 marks: nine ratio parts and 20 L per part
- 2 marks: original volumes 40 L and 140 L
- 2 marks: 15% loss is 27 L; usable total 153 L
- 2 marks: usable volumes 34 L and 119 L, with additive checks
- 2 marks: explains percentage-versus-fixed loss, part-to-part versus part-to-whole ratio, and the uniform-loss assumption
- Total ratio parts = 2 + 7 = 9; each part is 180 ÷ 9 = 20 L.
- Before transfer: A = 2 × 20 = 40 L and B = 7 × 20 = 140 L; check 40 + 140 = 180 L.
- Loss = 0.15 × 180 = 27 L, so usable volume = 180 − 27 = 153 L.
- Uniform loss leaves 85% of each colour: A = 0.85 × 40 = 34 L, B = 0.85 × 140 = 119 L; check 34 + 119 = 153 L.
- 15% of 180 is 27 L, not 15 L. A is 2/9 of the whole, not 2/7; 2/7 compares A with B. Unequal losses would change the usable ratio.

Aufgabe 5: Chemie — Stoffe, Reaktionen und Erkenntnisgewinnung
20 Punkte
Eine Schülervertretung bewertet zwei dokumentierte Wärmespeicher-Materialien für ein Modellprojekt. Alle Daten stammen aus einer Simulation; es findet kein eigenständiger praktischer Versuch statt.
Daten und Belege
- Material A: Masse 180 g; Volumen 75 cm³; Temperaturanstieg in drei Läufen 8,1 K, 8,4 K und 8,2 K.
- Material B: Masse 156 g; Volumen 60 cm³; Temperaturanstieg 10,0 K. Für B liegt nur ein Lauf vor und die Ausgangstemperatur wurde nicht dokumentiert.
- Eine Werbeaussage lautet: ‚Das dichtere Material speichert automatisch mehr Wärme und ist deshalb immer nachhaltiger.‘ Angaben zu Lebensdauer, Energieaufwand und Entsorgung fehlen.
Berechne die Dichte beider Materialien, werte die Messreihe von A mit Mittelwert und Spannweite aus und prüfe die Werbeaussage. Formuliere ein Sachurteil und anschließend ein getrenntes, bedingtes Werturteil.
Vertiefung: Entwirf einen fairen simulierten Vergleich: Benenne Einflussgröße, Messgröße, mindestens drei Kontrollvariablen, benötigte Wiederholungen sowie eine Information, die für die Nachhaltigkeitsbewertung noch fehlt.
Bewertungskriterien und Lösungshinweise
- Dichteberechnungen mit korrekten Einheiten
- Transparente Auswertung von Mittelwert und Spannweite
- Dichte, Wärmeverhalten und Nachhaltigkeit werden nicht gleichgesetzt
- Lücken und Unsicherheiten des Vergleichs werden erkannt
- Sachurteil und bedingtes Werturteil sind getrennt und evidenzbasiert
- Material A hat 2,40 g/cm³, Material B 2,60 g/cm³.
- Für A beträgt der mittlere Temperaturanstieg etwa 8,23 K, die Spannweite 0,3 K; die Einzelwerte bleiben Bestandteil der Evidenz.
- Die höhere Dichte von B beweist weder eine höhere Wärmespeicherung noch eine bessere Nachhaltigkeit; dafür fehlen ein passendes thermisches Modell und weitere Daten.
- Der Einzelwert von B ist wegen fehlender Wiederholung und undokumentierter Ausgangstemperatur nur eingeschränkt vergleichbar.
- Ein fairer Vergleich hält Masse oder Volumen, Starttemperatur, Energiezufuhr, Messdauer, Umgebung und Sensorik konstant und wiederholt beide Reihen.
- Eine Nachhaltigkeitsbewertung benötigt mindestens Lebensdauer, Herstellungsenergie, Herkunft, Wiederverwendbarkeit oder Entsorgungsdaten und eine transparent gewählte Gewichtung.
