The Preschool Scientist: Anatomy

Today we are going to use our pets or our toddler's favorite stuffed animals to reinforce the body parts. Learning body parts is an important goal for toddler self-awareness. In this short activity we are going to also show them that animals have the same parts as they do helping to build on their natural interest in animals. This type of activity works best when you only do it once through at a time, but repeat it often. This is a good time to also practice gentle hands if you are helping your child to point to the body parts on a family pet.

My toddler playing with Linguine (who is an amazingly
sweet and tolerant cat.)

First practice this following song with your toddler:

HERE ARE MY EARS
Here are my ears. (Child points to ears)
Here is my nose. (Child points to nose)
Here are my hands. (Child holds up hands)
Here are my toes. (Child points to toes)

Here are my eyes. (Child points to eyes.)
Both opened wide. (Child opens eyes wide)
Here is my mouth. (Child opens mouth)
With white teeth inside. (Child smiles showing teeth)

Once your little one is familiar with the song adapt it for animals (stuffed or real) that you see around you. For example we have a cat named Linguine so I sing,

Here are kitty’s ears. (Child points to ears)
Here is kitty’s nose. (Child points to nose)
Here are kitty’s legs. (Child holds up hands)
Here are kitty’s toes. (Child points to toes)

Here are kitty’s eyes. (Child points to eyes.)
Both opened wide.
Here kitty’s mouth. (Child points to mouth)
With white teeth inside.

I hope you enjoy this simple and easy to repeat activity. Next week’s preschooler activity will be hunting for creepy crawlies outside and it is very well suited for all age groups so I will be substituting a book review on Toddler Tuesday instead of an adapted activity, be sure to stop by to see what science books we are reading at our house. (With shameless promotion of my Usborne site as this month’s book happens to be an Usborne book). Till Saturday, keep exploring!

Song from the following great resource for toddler lessons: http://www.preschoolexpress.com/

Last week, The Preschool Scientist focused on helping our children to understand what they look like on the inside, specifically their bones. Today, we will be extending that understanding to animals. The goals of this lesson are first to help children understand that familiar animals have the same basic body parts as we do and also have bones. The second goal is to introduce the idea that animals have lots of similarities with one another. When children understand that animals have bodies similar to ours it inspires both wonder at the variety that they see on our outsides and empathy for other species. This activity requires very few materials and makes no mess so it would be a great one to do at a Doctor’s office or anywhere that had a wait so long as skeletons had already been printed out. Finally an educational use for all those stuffed animals that seem to constantly find thier way into your house!

Parent Background Guide Our lesson today is really a study of basic comparative anatomy. In comparative anatomy, scientists look at bones and other structures in different organisms to see the similarities and the differences. This allows them to group and classify these organisms and before we could test DNA it helped scientists to determine which animals were related to each other. One of the most striking similarities to me is how similar human hand bones are to whale flippers, yet they perform utterly different functions. In general, animals with a spinal cord are most often studied. Comparative Anatomy is still a very useful study today and is very valuable to the study of dinosaurs in the field of paleontology where no DNA evidence exists.

This week’s activity

Materials

2-3 Stuffed animals chosen from the list below

Access to the internet or printout of the human skeleton and those of the animals you have chosen.

Preparation: Choose or allow your child to choose 3 stuffed animals that are interesting to them. Realistic animals would be preferred, but choosing an animal to which your child has a connection would also be very valuable. For the purposes of this lesson snakes would be confusing.

Discovery time: Line the animals up along a couch, chair, table and begin by helping your child find similar body parts on each animal. Where is the head, the stomach, how many feet does it have, where would the ribs be?? Look at each animal to verify that all of them have the body parts in question. Instead of asking all the questions, encourage your child to name body parts and you can each take turns finding them. After you have illustrated that each animal has the same basic parts (and maybe some different ones) take out or view the pictures of the skeletons. Encourage your child to first match each skeleton with the animal. This may require lots of help and hints, but try to avoid doing it for your child. Next, ask your child to point to things that are similar. All vertebrates have a skull, vertebrae, four limbs, rib cage,{hands, flippers, feet, wings}.

Tying it together: Now that your child has the general idea that we are all made out of the same parts, both inside and outside, make sure to connect that knowledge with other animals that they see in the world around them. This will help to get your child thinking about their bodies and the bodies of animals as well. For example, if you see a bird flying remind your child that their arms are similar to the bones in the bird’s wing. What do they think it would be like to fly?? The idea here is that knowing our similarities can help children to image what it would be like to be another animal or to determine what is different that makes them different from that animal. Horses can run faster than us, this is because they use four legs to run whereas we use two of our “legs” to do other things like carry toys.
