This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.

In this activity, learners sniff out scents hidden in balloons! After investigating, learners discover we sometimes can use another sense (smell) to detect things too small to see.

This activity was designed for blind learners, but all types of learners can use it to learn to differentiate between qualitative and quantitative observations and to practice data collection.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.
