Activity: Find out more about your favorite “K” nature word!
This activity — similar to show and tell, but without bringing an actual kangaroo or koala to your house — will help you dig deeper into the words on our list.
(Tip: This activity is best done with a group of classmates or friends!)
Step 1: Choose your favorite word on our list (or pick one at random)!
If a certain word on our list stands out to you or interests you more than the others, pick it.
If you’re struggling to choose between all of the cool things that start with K, pick a number one through 57 and see which word you get.
Step 2: Look at our definition, then find more information about the word.
We provide basic definitions for each of the nature words that start with K above, but there’s plenty more to know about each of these plants, animals, and other natural features.
After taking a look at our definition, see if you can find any books, encyclopedia entries, or websites dedicated to your nature word.
Gather facts like where it is found in the wild, its scientific name, and any other interesting details you find.
Look for pictures, too, so you can see what your nature word looks like in the real world!
Step 3: Share your findings!
Put together a poster, slideshow, or video to share all of the facts you find about your nature word!
Show off your new knowledge to your family — or, if doing this activity with friends or classmates, you can present your findings to each other (online or in-person).
