This week, we are going under the sea to explore whales with one of our fun Ocean STEM activities!
Have you ever really wondered what it would be like to stand next to a whale?
I would love to go on a whale watch one day -- and both of my kids are been crazy for whales. Go figure, we live in Kansas - the most landlocked state in the country, and they are all into whales.
So we decided to explore a little about whales this week and learn just how big they really are!
How Long is a Blue Whale?
Here's what you'll need for this activity:
- a Tape Measure -- with a locking feature like ours since you'll be measuring a long distance
- a large bucket of Sidewalk Chalk (bring extra!)
- a picture of your favorite whale
- the length of your whale -- you can use one of the books below to look up it's size
Step 1: Measure Your Length
The first thing you'll need to do is measure out the length you'll need for your whale.
We decided to draw a blue whale (yep, one of the biggies in the ocean!) so we had to measure out 100 feet!
Did you get that -- 100 feet!
So, you ask, where the heck do we find that kind of room?
Great question! We headed to our school parking lot since school is out of session. You can also try the blacktop at a local playground too.
We used our chalk to draw a line that measured 100 feet! We had to use the length of our tape measure four times over so you may have to measure, then mark and then measure some more :)
And we also ran out of chalk while drawing our line so one piece of chalk may not go as far as you think when drawing -- bring a LOT!
Making a chalk the length of your proposed whale (you can also do a shark or a manta ray, etc) will help as you while drawing so you don't have to keep measuring out the distance or holding down the tape measure while you work.
Step 2: Draw Your Whale
Then we got to work drawing "Bluey" our big blue whale.
We used blue pieces of chalk to draw an outline of the whale. You can make it as detailed as you'd like (we added the fins and some of the features on the whale's head using while, yellow and pink chalk to make his features 'pop' a little more).
You can also choose the color based on your whale. Use while if you want to draw a Beluga, gray for a sperm whale or gray whale, etc. Obviously, we chose to use blue ;)
Step 3: How Big is a Blue Whale?!?
This was really the best part!
To get an idea of how big these beautiful creatures really are, you can try a few things. We stood on opposite ends of our drawing so that we were 100 feet away from each other. That really made an impression on my daughter to see how much "whale" would be between us!
You can also have your child sit next to the drawing while you take a photo -- then they can see how they measure up to their favorite sea creature.
And if you want to add in a little math, bring along your bike and see how many bikes it would take to equal the length of the whale. You can see that we had our car with us and it was dwarfed by our drawing!
Great Books about Whales
And we wanted to include a few of our favorite books about blue whales (with affiliate links so you can review them):
The Blue Whale is a gorgeous non-fiction picture book with amazing details. Readers can see just how large a blue whale's eye really is as they gaze into it and learn many details about it's large size. Beautiful illustrations here!
We love the photographs in Face to Face with Whales ! They are so detailed that you are able to see all the amazing features of whales. I'm awestruck at how they got so close for many of these photos.
Is a Blue Whale the Biggest Thing There Is? is a wonderful book that gives kids an idea about how big things really are in the world. It's a great read for a math discussion about relative sizes and how things compare to each other.
And the Big Blue Whale: Read and Wonder book is a beautiful read. It includes excellent information about the blue whale and a nice double-page spread to give you an idea of it's size in comparison to a human. And I just love the drawings in the book.
Billy Twitters and His Blue Whale Problem may not be a non-fiction book but it has so many cool comparisons sprinkled through the story, we just had to include it! The story follows Billy Twitters as he tries to take care of his new *pet* whale -- very funny read aloud!
