King Bidgood's in the Bathtub
King Bidgood's in the Bathtub is a wonderful story by Audrey and Don Wood about a king who loves baths and playing in the bathtub. The story of King Bidgood is a great jumping off point for studying Medieval Times, Hygiene, or sorting and categorizing.
In this unit study we will explore displacement with Archimedes, learn a little sign language, and do a lot of water experiments. There are ideas for learning new vocabulary and songs to sing.
So Rub a dub, dub, let's start learning with King Bidgood in the bathtub.

How do Tubs Work, King Bidgood?
King Bidgood Loves to Read

King Bidgood loves his tub so much that he decides to read about plumbing, bathrooms and water. Here are some of his favorites.
When King Bidgood gets out of the bathtub he likes to play games like Waterworks, a game about connecting pipes.
Parents often give me left over PVC pipes. We use them in the Block Center where the children use them to create the most amazing structures.
We also use Marble Run to get the idea of how pipes must be connected in order to make sure that the water runs through without leaks.
Books in the Bathtub
King Bidgood reads Tub Books
Do you or one of your parents have an old tub lying around? An old clawfoot tubs is perfect for turning into a reading nook. Just add some pillows, a few books and some eager readers.
You might like to have some King's Crowns for the children to wear when they are reading in the tub so that they can pretend to be King Bidgood as they read.
With only 10 words, Patty Wolcott's book, The Marvelous Mud Washing Machine is perfect for the very beginning reader. King Bidgood is a great read aloud and Tabby in the Tub is perfect for readers that are just taking off into chapter books.
King Bidgood Invents a Washing Machine
If you have not yet read Marvelous Mud Washing Machine be sure to get a copy today. It is not only a perfect book for a beginning reader, it is also just a fun book to read.
When King Bidgood writes on the Wall...
King Bidgood can Scrub it off again!

King Bidgood spends so much time in the tub that he might even do his writing in the tub. These crayons write on walls and are easily cleaned off. Children love to practice spelling words, handwriting or writing messages to eachother when given permission to write on the wall.
After the children have written their spelling words on the wall it's time to scrub them off again. But they must be scrubbed off in the right order. Give clues such as:
1. Scrub off a word that starts with "b" as in Bidgood.
2. Scrub off a word with a short u in the middle.
etc.
This is also a great way to practice handwriting.

Books for the Bathroom
King Bidgood loves to Read
These are great read alouds that I love to keep in a basket in the bathroom. They encourage children not only to read but also to take a bath.
In the classroom it can be fun to get an old clawfoot tub, paint it bright colors, add pillows and use it as a Reading Nook.

And who do you think they be?
The butcher, the baker, the candlestick maker.
Turn them out knaves all three.
Make costumes for 3 dolls and dress them as the butcher, the baker and the candlesick maker. Put them in the tub with copies of Nursery Rhyme books for the children to read.
Archimedes' Bathtub
Read the book Mr. Archimedes's Bath.
Archimedes discovered that he could measure the mass of objects by using displacement of water.
1. Set up a balance scale in the sink.
2. Fill two equal sized dishes completely with water. (Be sure to model this procedure and have children experiment with filling the dishes completely.)

Photo Credit: Displacement Experiment
in the public domain
The book Sign Out Science explains in very clearly how to do an easy experiment using Archimedes discovery of how to determine the mass of an object by displacement of water.
1. In the Sink set up a large bowl. Use a waterproof marker or tape to make a line around the inside of the bowl to show the level of the water.
2. Model how run the water in to just the right level.
2. Place objects to be used for observing the displacement in a dishpan next to the sink.
4. Model how to keep hands down so that water doesn't spill onto the floor. Cover the floor with towels. Children might stand on chairs.
5. Allow the children to experiment with various objects.
6. As a class, discuss and record their observations.
I found in my classroom that the children loved this activity so much that they often wanted to continue during recess. Many of them wrote about this experience during Writing Workshop.
King Bidgood meets Archimedes
Displacement Experiment

Archimedes
Available on Allposters
Set up the Sensory Table with water and aluminum foil.
Children try to make boats that float.
On the shelf under the Sensory Table label two dishpans: Float and Sink.
After the children have had turns experimenting with making boats, take them out and observe them carefully. Use a digital camera to take pictures. Record your observations and make a class book.
A demonstration of the Law of Archimedes. The boat floats easily but the bail sinks. Why? Because the boat displaces much more water than the ball

King Bidgood Vs. Archimedes
King Bidgood plays a Board Bame
- Archimedes Board Game
- Originally published in the July 1988 issue of GAMES Magazine, Archimedes is a nautical battle game for 2 players.
Archimedes can be played with a standard checkers set. The board is an 8X8 grid, and each player has 12 "ships" represented by checkers of one color. The object of the game is to capture opponent's ships in an attempt to land on the enemy's home port.
Math: King Bidgood Sorts his Toys
King Bidgood's Adventures in Recycling

on Photobucket
To expand on this aspect of the book you can sort objects in math for different attributes.
1. Set out a junk box and ask children to sort them
2. Ask them to take pictures of the final sorting.
3. They should be able to explain the criteria for the way they sorted them.
4. Help them label their pictures and then make them into a class book.

Photo Credit: Junk Box Counting
on PreKinders
At the beginning of the year I ask parents to send in small objects for our Junk Box. Things like keys, buttons, knobs, handles, etc. Any small objects that no longer have a purpose. We use these for counting, sorting, art projects and science experiments and it's a great way to promote recycling.
King Bidgood Where Are You Going?

King Bidgood, where are you going?
King Bidgood, with legs like toothpicks and
a neck like a giraffe.
King Bidgood, got in the bathtub,
pulled out the plug and then.
OH MY Goodness,
OH MY SOUL,
there goes King Bidgood down that hole.
King Bidgood, where are you going?
Glub, Glub, Glub.
King Bidgood and his Tub

Children love to retell the story of King Bidgood. These props help to extend the story and help develop new story lines for King Bidgood.
Later the children may write these stories during Writing Workshop.

Shower or Bath
It's time to weigh in.
Which way do you prefer to get clean?

Shower
scarlettohairy says:
For everyday, a shower. A bath is for relaxing!
Lizblueberry says:
Definitely shower!!!
Evelyn_Saenz says:
King Bidgood prefers a bathtub but I prefer the shower. I write on the walls and spray it all off with the hose. Showers are so much fun!
tonyab says:
I'm usually in a hurry - shower is best for me.

tandemonimom says:
Four small homeschooled kids ... quick showers for me!
says:
showers for everyday, baths when I want to relax.
Mortira says:
Showers are more eco-friendly, and I just feel cleaner when I have gravity helping out. I save baths for when I'm not feeling well.
Bathtub
Brick_House_Fabrics says:
Bath, always!
andreaberrios says:
I just love the bathtub! My favorite.
Pastiche says:
BOTH! I relax in the tub, then shower off all the bubbles.
Evelyn_Saenz says:
In the bathtub with a few candles and a good book.
groovyoldlady says:
Overall? I'm a tub soaker (and reader and crossword puzzle doer). But if I'm really grungy and dirty from yardwork, only a shower will do.
King Bidgood becomes a Scientist
Bathtub and Shower Experiments
- Shower vs. Bath, an experiment
- 1. Measure the amount of water it takes to take a shower by putting in the plug when taking a shower.
2. Does water always turn in a certain direction when going down the drain? Email someone in the southern hemisphere and ask them to do the same experiment. Does it go clockwise or counter-clockwise?
3. Does your voice sound better when singing in the shower?
King Bidgood's Short u Phonics Activity
Short u or Long u Vowels
King Bidgood only wants to play with the ducks with a short u vowel sound. The ducks with the long u are put in the basket.
Make a bulletin board with King Bidgood in the bathtub. Place two hooks on the wall labeled underwear and uniform and hang one under each corresponding hook.
Put a toy basket beside the tub for words that don't have the short u vowel sound.
On the tub write Short u.
Tell the children that King Bidgood has decided to play with his ducks today but he will only play with ducks that have pictures with a short u sound in the middle.
Make a stack of ducks with pictures on one side and the words on the other.
Note:You could put the symbol over the u for the short or long sound for self checking.
The children listen for the short u sound in the word and either put it in the tub or in the toy basket beside the tub for another day.
King Bidgood is finally ready to get out of the tub. What will he wear?
His underwear or his uniform?
Well, he has declared that it is short u day so of course only his underwear will do.
King Bidgood Declares Short u Day!

When King Bidgood finally does get out of the tub he feel cool. The water in the tub was warm and the air in the room is warm. What's going on?
Robert Krampf has an experiment with scientific explanations to go with it. All you need is warm water and a washcloth.
- Evaporation Air Humidity Bathtub Experiment
- Science experiment 264. A Cool Experiment. Why you feel cool when you get out of the tub.
It's a good thing that King Bidgood likes to Bathe.
Why both you and King Bidgood need to keep clean...
Bathtub Science
1. Use a clear plastic cup.
2. Push a crumpled piece of paper down to the bottom of the cup.
3. Hold the cup upside down and push it to the bottom of the tub full of water.
Because of air pressure, if you held it straight no water will go into the cup and the paper will stay dry.

- The Crafty Teacher: 107 Things to Put in Your Sensory Table
- 1. Sand
2. Water - plain or lightly colored
3. Water with liquid soap or bars of soap
4. Rice - which can be colored with food coloring if desired
5. Pasta - one kind or a mix; can also be colored
6. Snow
7. Fake snow - it's awesome!
8. Hay
9. Soil - use organic for safety; add live worms if you're brave
10. Sod
These are just the top ten. There's lots and lots more. - Science in the Bathtub
- The best way to support children's science exploration is to help children do their own thinking rather than tell them facts. This inspires your child to do exactly what scientists do: observe closely, make predictions, try things out, and make thoughtful conclusions.

- Evelyn-- Another wonderful lens! My daughter and I saw this in the doctor's office yesterday and I wouldn't have picked it up (she's 10 going on 14), but I remembered you had a lens on it. We had fun giggling and taking turns reading the pages to each other while waiting for the doctor. She thought it was very "random".
Just like tandemonium said, I adore your talent for spinning one idea out into a study of many, many different concepts! Five stars!
