Smell is a very powerful sense. When we tune into our sense of smell, we notice all kinds of things. In addition to getting kids thinking about their sense of smell, this experiment is a great way to get them outside and active!
Just be sure to check with parents before doing this walk outdoors. If the kids have asthma or allergies to pollen, it may not be a good idea to take them outside!
You can also let kids have fun with smell by putting different things in a bag or jar, blindfolding the kids, then letting them sniff and guess at what's inside. Try this with lemon and/or orange peel, bananas, vanilla, vinegar, onion, mint, pine needles, and pencil shavings.
Just be sure to avoid anything kids might be allergic to. Some allergies — like nut allergy, for example — can turn into serious emergencies even if a kid breathes in nut particles. You don't want to have a medical emergency on your hands!
