Wild Horse Scientists Book Activities

The newest book in the Scientists in the Field Series, Wild Horse Scientists by Kay Frydenborg, is sure to inspire older children to become scientists, especially if they are interested in horses. It follows biologists as they try to figure out the best ways to study and manage horses in the wild. Remarkably, very little was known about wild horses until the last few decades.

Note: this book is recommended for ages 10 and up at Amazon, but I would say ages 12 and up. Be aware up front that it contains photographs of dead, decaying horses and discusses birth control methods. It is not a picture book! For a full review of the book, see our sister blog, Wrapped In Foil.

Horse Science Activities:

1. Horse Coat Color

One of the first tasks when studying horses is to learn the names of all their coat colors so you can communicate accurately with other horse scientists. Coat color in horses is controlled by several genes, resulting in over twenty different combinations.

Do you know your horse colors? Pick out the bay, palomino, chestnut, and pinto from the photographs below. Here is a poster of horse coat colors (click to enlarge) to help.

A. What color is this reddish-brown horse?

B. What about a red-brown horse with black lower legs, mane and tail?

C. What is the name of the color of this flashy horse? (Notice it has blue eyes instead of brown).

D. What about this yellow one hiding behind the thistle?

Answers:

  • A. Chestnut
  • B. Bay
  • C. Pinto
  • D. Palomino

Some people, sometimes even horse people, might call C. a paint, but technically it is a pinto because it doesn’t have any quarter horse bloodlines. Only horses that have quarter horse (or thoroughbred) breeding are called paints when they have extensive white markings.

Older children might want to investigate the genetics of horse coat color. Jennifer Hoffman has a very cool interactive lesson to explore horse coat color genetics.

2. Horse Anatomy

Being domesticated animals, we have developed and extensive vocabulary to name the parts of the horse.

See if you can fill in the names of the parts of the horse below.

3. Horse Behavior

Although horses can’t talk, you can tell what is going on with them by watching their movements.

This video explains some of the basics, such as what the positions of the ears and tail mean, as well as the fact that horses can not see directly behind themselves. Always avoid approaching a horse from the rear or near their tail because you will be in their blind spot.

4. Horse Senses:  Vision

Ever wondered how scientists study things like what an animal can see? Check out the photos of vision research using choice tests with horses (scroll down to see photographs of research in action).

Using a choice test technique, the scientists were able to determine that horses can see certain colors, but their vision is similar to a human with red/green colorblindness.

Although scientists are starting to learn more about horses, there are still a lot of questions.

Here Come the Humpbacks with some Whale Science Activities

Our science activities are inspired today by the new picture book Here Come the Humpbacks by April Pulley Sayre and illustrated by Jamie Hogan. Did you know that humpback whales are found both in the Atlantic Ocean and the Pacific Ocean? The book follows the migration of a mother humpback and her baby from the Caribbean Sea to the New England coast and back. During the trip the reader learns about the lives of whales and the challenges they face, all the while absorbing new vocabulary. (For a full review, see our sister blog, Wrapped In Foil.)

1. Whale anatomy

Right in the beginning of the book, the words flippers and flukes are used. What do they mean?

The flukes are the lobes of the whale’s tail. There two flukes, one on either side as seen in the photograph below.

(Photograph by Captain Budd Christman, NOAA Corps )

The flukes are important for several reasons. First, they help push the whale through the water as the whale moves its tail up and down.

The whales also use their flukes to slap the water, possibly to communicates with other whales.

For scientists, the flukes are important because each fluke has a distinct color and pattern of notches and grooves and can be used to identify individual whales.

The flippers on each side are used both for swimming and for steering the whale through the water. Humpback whales have extra long flippers compared to some other whales.

Other vocabulary:

  • Blowholes– the opening in the top of the whales head where it breathes
  • Baleen– the fibrous-like material in the whale’s mouth that it uses to filter its food from the water (some other types of whales have teeth).
  • Dorsal fin– the flap that sticks up on the back of the whale, relatively small in the humpbacked whale

Activity suggestions:

2. How big is a humpbacked whale?

Adult female humpback whales weigh about 45 tons and are about 45 feet long. The adult males weigh about 42 tons and are roughly 42 feet long. Compare that to a large school bus, which can be about 40 feet long.

Check How Big is Big? for an animated size comparison to a right whale and a ship.

3. Whale behavior – communication

One of the most fascinating aspect of whales is that they “sing” to each other under water.

The Right Whale Listening Network has recordings of both right whales and humpbacks, as well as fish sounds. Fun!

Groundhog Day Science

Our science activities and lessons today are inspired by the children’s picture book Groundhogs (Pebble Plus: North American Animals) by Chadwick Gillenwater. With Groundhog Day just two weeks away (February 2, 2013), it would be a great time to learn more about groundhogs and do some science activities relating to shadows and weather. For more about the book and other books for the celebration of Groundhog Day, visit Wrapped in Foil.

1. Learn about groundhogs or woodchucks and create an age-appropriate fact sheet.

Groundhogs, also called woodchucks, are rodents belonging to the marmot family. Their scientific name is Marmota monax. They live throughout the eastern and northern parts of North America, all the way north to Alaska.

Groundhogs live in burrows they dig in the ground. They come out of the burrow to eat plants during the summer. Often you can see them alongside highways grazing on the road banks or sitting up looking for danger. Sometimes they climb small trees or shrubs to escape from enemies or to explore new types of food.

In the winter groundhogs hibernate deep underground. Sometimes they will come out of hibernation to search for food. This has become part of the Groundhog Day story.

Groundhogs are also called whistle pigs because they whistle to communicate with each other. The Marmot Burrow website has a recording of a male groundhog whistling.

In this video, you can see a young groundhog and learn more about their habits.

For a longer and more extensively narrated video about a woodchuck family, see Groundhogs 2005-2008 An uncommon look at a common animal. The link takes you to the video at YouTube (sharing has been disabled). Update:  See the videos on the new website.

You also might want to read some of the books listed below. When you are done, create a fact sheet about groundhogs to share what you have learned. Include drawings of the animals and their homes.

2. Science of Shadows

A. Preschool-K Level:  Exploring Shadows

Gather:

  • flashlights
  • bare, light-colored wall in a darkened room (ceiling is fun, too)
  • assorted objects to cast shadows, including a wide-toothed comb or hair pick, and a ball

Darken a room somewhat and then use the flashlight to explore shadows. Move an object closer to the flashlight and then farther way. Move the flashlight closer to the object and pull it away. What happens? What happens when you hold the comb in front of the flashlight? Now turn on a second flashlight. Shine the two flashlights on an object. Slowly move the flashlights apart. What happens to the shadow(s)?

Older children will enjoy making shadow animals and/or shadow puppets.

How about a groundhog shadow puppet to celebrate Groundhog Day? Cut out a groundhog shape and glue it to a craft stick with white glue. Now take it outside and see if the groundhog will see its shadow.

B. Elementary:  Chasing shadows

Need:

  • Hard level surface out of doors large enough for each participant to record their shadows
  • Sidewalk chalk of different colors
  • Yardstick or measuring tape (optional)
  • Compass (optional)
  • Sunny day

Start by going outside in the morning. Have the children chose a place to stand. Draw a circle of chalk around their feet and then write their initials inside the circle. Now, have them stand with their back to the sun. Have a helper draw a line around their shadow. Measure the length of the shadow. Check the direction of the shadow using the compass (optional).

Return and repeat the process around noon and later in the afternoon. How have the shadows changed? Discuss how the shadows might be different in the different seasons as the sun appears to be higher or lower in the sky due to the Earth’s tilt.

C. Older:  Make a sundial

There are many great websites that show how to make an explore a sundial. Here are just two:

D. Older:  Use a shadow to measure a tree.
