Help!?
What can we use if we don't have a magnifying glass or small bags for the rock samples?
If you don't have a magnifying glass for the 'Use a magnifying glass' step or small bags/boxes for 'Put each sample ... in its own bag', use your smartphone camera in macro mode or a jeweler's loupe to inspect textures and resealable plastic bags or clean paper envelopes to store and label each numbered sample.
Why can't I match a sample to a rock type and what should I try?
If you can't match a sample to a rock type when following 'Match each sample to a rock type using your notes', double-check the six facts and your texture sentences in your notebook, retake brighter close-up photos or re-examine grain size with a hand lens, and compare with images from the trusted places you listed.
How can this activity be changed for younger or older kids?
For younger children, simplify the project by picking 1–2 samples, drawing them, and saying three simple facts aloud while an adult writes them in the notebook, while older kids can expand the 'Read and write down at least six interesting facts' step to include mineral composition, cite sources, add scale bars to photos, and build a detailed slideshow.
How can we make the poster or slideshow more interesting or scientific?
To enhance your 'Types Textures Formation and Facts' poster or slideshow before you 'Take a clear photo of your finished poster or save/export your finished slideshow file', add a 1 cm scale next to each photo, a one-line hardness or scratch-test note under each caption, a mini-map of collection sites, and a short audio narration or video clip for at least one sample.
