Desert Science Books and Activities

February 13, 2015 / / 2 Comments

Today we were inspired by two new picture books about deserts and desert animals. See full reviews at our sister blog, Wrapped in Foil.

Get to Know Gila Monsters (Get To Know Reptiles) by Flora Brett is a simple text for beginning readers that helps sort myth from facts about this unique lizard found only in the desert Southwest.

A Day and Night in the Desert (Caroline Arnold’s Habitats) by Caroline Arnold reveals which desert creatures are active during which parts of the day and night. Although it centers on animals and plants found in the Sonoran desert, the book also contains a map showing where deserts are located throughout the world.

Desert Mammals Activity

We often think of cacti and reptiles when we think of deserts, but as A Day and Night in the Desert shows, there are quite a few mammals found in deserts as well.

Some mammals found in deserts:

  • Jackrabbits
  • Coyotes
  • Foxes
  • Ringtails
  • Coatis
  • Skunks
  • Cougars
  • Bobcats
  • Bighorn sheep
  • Javelinas
  • Bats
  • Ground squirrels
  • Mice
  • Packrats
  • Rats

Pick a desert mammal and find out more about it.

This ground squirrel is all puffed up on a cold morning.

For example, is the mammal diurnal or nocturnal? Is it active all year around or does it hibernate for part of the year? What does it eat? What is its life cycle? Does it have any special ways to conserve water in the desert?

javelinaWhat are these javelinas (also called collared peccaries) doing to keep cool?

Create a lapbook, poster, diorama, or report about your findings.

Resources to check:

1. The AZ-Sonora Desert Museum has an extensive list of fact sheets about desert bats as well as fact sheets about other desert animals and plants.

2. Pima Community College in Tucson has online facts about desert mammals

3. Arizona Naturalists has information about Sonora desert mammals

4. Tohono Chul Gardens has a number of desert related handouts on their website. Scroll down to “Fun and Smart Projects for Kids,” and look for links to the Desert Pathfinders Activity Booklet (this link takes you directly to the .pdf), Saguaros, etc.

5. Look for the Desert Habitats activities page on our Growing With Science website.

Exploring the Energy Potential of Oceans with The Next Wave

January 9, 2015 / / 1 Comment

Today for STEM Friday we are featuring The Next Wave: The Quest to Harness the Power of the Oceans (Scientists in the Field Series). Author Elizabeth Rusch introduces us to a number of scientists who are working hard to convert the mechanical energy of ocean waves into electrical energy. See a full review at our sister blog, Wrapped in Foil.

Waves are actually very complex and we are still learning about them.

How do waves form?

The waves in the ocean form due to wind blowing on the surface. The shape and size of the waves depend on the force and steadiness of the wind, and the distance over which the wind travels, called “fetch.” The shape of the wave is also influenced by the depth of the water, especially as it meets the shore.

Activity 1. Exploring Waves

Gather:

  • Plastic bin
  • Water
  • Food coloring
  • Dropper

You may use a sink or bathtub to hold the water, but because you will be blowing across the surface, a plastic bin situated on the waterproof surface of a counter or tabletop will probably be easier to maneuver around. This would be an ideal activity to try outdoors.

bin-with-water

Fill the bin 3/4 full of water.

Ask the children if they have ever been to the ocean and seen waves. If they have not, consider showing a video (YouTube has dozens).

ocean-waves-ca

Brainstorm about how to form waves. If water splashes are not a problem, allow the children to free-explore their ideas about how best to produce waves. They will probably put their hands in and swirl the water.

Now reveal that waves are formed by wind blowing over the water. Have the children blow and see how the waves look different from those they produced using their hands.

Did they form in parallel lines like in the video above?

Once the children have seen waves, add a drop of food coloring to the water and have them blow waves again. How does the water move? Do all layers move the same way?

Many texts will tell you that the water in the deeper part of the ocean does not move forward as a wave passes by, but simply travels in a circle or oscillates. Proof is given when an object floating in the water simply bobs up and down, rather than moving forward.

If you look closely at the second video, however, you will see that the top layer of the water with the food coloring moves across the surface with the waves. Why?  One possible solution is that the bin is too shallow and the waves are behaving more like those at the shore, where the circular motion is disrupted. Can you think of any other reasons?

Activity 2. Water Vortices

Older students might want to try the experiments with vortices suggested in this video by Physics Girl (has a pop-up ad):

Isn’t that incredible? I can’t wait until it is warm enough to try it myself.

If your children like these activities with waves, be sure to pick up The Next Wave: The Quest to Harness the Power of the Oceans (Scientists in the Field Series) . It introduces young readers to an exciting new technology that will capture the energy of waves and convert it to useful electrical energy. The book will definitely inspire young readers who want explore waves and oceans. It is also a great resource for adults who want to learn more about this relatively new area of research on a potentially renewable source of energy.

Sea Turtle Science For Kids

December 5, 2014 / / 0 Comments

Today we were inspired by two books about sea turtles. The first is Sea Turtle Scientist (Scientists in the Field Series) by Stephen R. Swinburne. This book for middle grade students reveals Dr. Kimberly Stewart’s efforts to investigate and conserve sea turtles on the Caribbean Island of St. Kitts. See a full review of the book at our sister blog, Wrapped in Foil.

For younger readers, we found Leatherback Turtles (Reptiles) by Mandy R. Marx with consulting editor Gail Saunders-Smith PhD. This is part of a series of informational books about reptiles featuring short sentences and carefully controlled vocabulary perfect for beginning readers.

Learn about sea turtles:

Sea turtles are pretty amazing creatures. There are currently seven recognized species:

  • leatherback sea turtle
  • green sea turtle
  • loggerhead sea turtle
  • Kemp’s ridley sea turtle
  • hawksbill sea turtle
  • flatback sea turtle
  • olive ridley sea turtle

The leatherback sea turtle is in a separate family from the other species. It is the largest turtle, and it is also unique because it lacks a hard shell. Baby loggerheads hatch out of eggs laid in the sand on beaches. The little loggerhead turtles crawl to the sea where they live for 20 to 30 years before they reach maturity. Amazingly, once they are fully grown, the females return to the same beach where they hatched out to lay their eggs.

The Kemp’s ridley and olive ridley also return to the beaches where they hatched to lay eggs. These two species, however, are a little different because many, many females return to the same beaches, all at the same time. These mass landings of female sea turtles are called “arribadas.”

This video shows a sea turtle arribada from Costa Rica. WARNING for little viewers:  The video does show eggs coming out of the female’s body. There’s also a graphic scene of vultures feeding on a dead sea turtle around the 2:20 minute mark (near the end).

Scientists are studying how sea turtles can remember the beaches where they hatched and how they know which way to swim to return. One thing they found is that sea turtles can sense the Earth’s magnetic field and use it as a guide.

 Did you know that…?

Like whales and dolphins, sea turtles must return to the surface to breathe.

Ways to help sea turtles:

Light pollution is a hazard to sea turtles. Newly-hatched sea turtles use light from the stars and moon and reflections on the water to navigate to the sea. If there are bright lights from human sources around their hatching sites, the sea turtles become disoriented and head inland instead of out to sea, which is usually deadly. Efforts are being organized to cut down excessive lighting along beaches while the sea turtles are hatching.

Finally, sea turtles mistake floating plastic bags for their natural food, jellyfish, and swallow them. The bags are not digestible and can cause death. Protect sea turtles and other animals by making sure plastic bags are properly recycled, or even better, use reusable cloth bags instead.

Related activities and links to lesson plans:

Download the discussion and activities guide for Sea Turtle Scientist at Steve Swinburne’s website, as well as posters, leaflets and find links to other great websites.

See Monterey Bay Aquarium’s Plastic in the Water Column lesson (scroll down to see link to .pdf lesson) as well as their open sea cam where you might spot a sea turtle.

For more information about related creatures, see our previous week of ocean-themed books and activities at Growing with Science.

Why not combine your STEM lesson with some great art by creating a watercolor sea turtle? Drawing and painting animals requires the same close observation skills so useful to scientists.
