Detailed instructions

1. Select a rock class from the Rock Class dropdown — choose Igneous, Sedimentary, Metamorphic, or Minerals, or leave it on Random for a mixed set.
2. Set the Number of Samples field to how many cards you want generated, between 1 and 8.
3. Click the generate button to produce the sample cards in the grid output.
4. Read each card's formation notes, physical properties, and field identification tips, then use the copy or save option to export the cards you need.

Use Cases

• •Reviewing Mohs hardness and cleavage patterns before a university mineralogy practical exam
• •Building a geology quiz worksheet in Google Classroom by generating cards across all three rock classes
• •Preparing labelled reference cards for a fieldwork trip to identify igneous vs metamorphic outcrops
• •Writing accurate specimen descriptions for a personal rock collection catalogue or club inventory
• •Creating exhibit copy for a school rock and mineral display with formation context and physical properties

Tips

• →Run the same rock class three times and compare results to spot which properties vary within a class versus which stay constant — that contrast is exactly what exam questions test.
• →When studying metamorphic rocks, pay close attention to the parent rock listed in the formation notes; understanding protolith relationships is a common weak spot in geology courses.
• →Use the generated Mohs hardness values to build a scratch-test sequence — arrange specimens from softest to hardest and practise ranking them before you have physical samples to handle.
• →For museum or exhibit copywriting, generate eight cards and cherry-pick the two or three with the most distinctive field notes — unusual streak colours or acid reactions make the most engaging label text.
• →If a generated mineral card shows metallic lustre alongside high specific gravity, cross-reference the streak colour — that combination narrows you down to the sulfide or oxide mineral groups very quickly.
• →Teachers: set the count to match your class size and use each card as a unique 'specimen tag' for a round-robin identification activity, so every student works with a different reference.
