She has some example things for them to look at, too. Just their surroundings are fairly interesting - distinguishing cushion from sand from stone isn't very hard but isn't quite trivial either, and each of those substances reacts slightly differently to being touched or tapped or having noise made near it. She'll distribute sticks to anyone who seems to be getting bored - they're freshly gathered this morning, so they're still slightly alive, and it's possible to sense their metabolism in addition to the sensations from touching, tapping, speaking to, or gently bending them - and make herself available if anyone mentions wanting to sense another person. As it approaches lunchtime, she gets the group's attention and switches the overhead portals from showing local daytime to night, then a sunset, then day on another planet; being able to sense environmental conditions is a particularly useful skill, with the teleportation, and this is an easy first thing to learn to look for - they can get into weather and gravity and such later.
