Super Sniffers: Amazing Animal Noses

Today on Discovery Rangers, we explored the amazing animal noses that can sniff out anything from a single dropped crumb to a hidden friend from miles away! Now, it's your turn to become a super sniffer with this fun at-home mission.

The Big Question

How can we explore our own sense of smell and compare it to the amazing noses of animals?

What You'll Need

• Small containers or bowls (at least 3)
• Various items with distinct smells (e.g., a piece of fruit, a spice like cinnamon, a flower, coffee grounds, a cotton ball with a drop of vanilla extract)
• A blindfold or scarf
• Paper and pencil or crayons

Mission Steps

1. Gather Your Scents. Place one smelly item into each container or bowl.
2. Blindfold Your Sniffer. One Ranger puts on the blindfold. The other Ranger presents the containers one by one.
3. Sniff and Guess. The blindfolded Ranger takes a careful sniff of each container and tries to guess what the item is.
4. Record Your Findings. After guessing, remove the blindfold to see if the guesses were correct. Draw or write down what you smelled and whether you guessed it right.
5. Switch Roles. Now, the other Ranger becomes the blindfolded sniffer!

Talk About It

• What was the easiest smell to identify? What was the hardest?
• How did it feel to rely only on your sense of smell?
• What kind of things do you think animals with super sniffers can smell that we can't?

Take It Further

For older Rangers (9-12), investigate how different animals have different numbers of olfactory receptors. Research how dogs' noses work and compare them to a bear's or a shark's. You could even try to draw a diagram showing how odor molecules work, like the "keys" fitting into "locks" on our olfactory receptors.

FAQ

Q: My child has a stuffy nose. Can we still do this mission? A: It might be tricky if their nose is blocked, but you can still talk about the smells and have them hold the items closer. Alternatively, they can be the "presenter" and guess which smell you are smelling. Q: What if I don't have many items with strong smells? A: Even subtle differences can be fun to explore! Try different parts of the same plant (leaf vs. flower) or different kinds of safe cleaning supplies. The goal is to practice identifying distinct scents.
