Learning About The Human Body Part 1: The Skeletal And Muscular Systems

At the end of each school year, I sit down with my daughter to discuss what topics she most wants to learn about the next year. One of her science topics she picked to study this year was the human body. Instead of ordering a boxed curriculum set, I decided to put together my own human body unit. In this 3 part series I will share some of the activities and resources we used for each of the body systems starting with the skeletal and muscular systems.

The Human Skeletal System


Our skeletons are the frame of our body. They give us structure, without them our bodies would be limp like noodles. They also provide places for muscles to attach so our bodies can move.


Why Does Your Body Need Calcium? Experiment:

This is a simple experiment you can do to explore why calcium is important for our bones.

You will need:

-several clean chicken bones

-vinegar 

-a bowl with a lid or plastic wrap to cover it

Let your child examine a clean chicken bone. Note how hard it is.

Place several clean chicken bones into a bowl and cover with vinegar. You should notice small bubbles forming on the bones. This is the product of a reaction between the vinegar and the calcium in the bones. 





Cover the bowl and set aside. After several days check your bones. They should begin to feel soft and spongy after a while. This happens because the vinegar has reacted with calcium in the bones. Calcium plays an important role in bone strength and hardness. Without it our bones wouldn't be as strong or hard.


Resources For Learning About The Skeletal System:

-Bones from The Dr. Binocs Show is a great video for kids about the human skeletal system.

-Bones And The Human Skeletal System from Ducksters has lots of general information about the human skeletal system plus an online quiz.

-Skeletal System from Biology Kids has lots of great information about bones, the human skeleton, x-rays, and more.

-Pasta Skeletons a fun anatomy activity from Martha Stewart 

-Skeleton Worksheet And Craft from Layers Of Learning 

The Human Muscular System

Our muscles are what allows our body to move.  Muscles are attached to bones with ligaments. When our brains send the signal, our muscles contract, moving our bones.

Articulated Hand Activity:

This is a really awesome hands on activity for learning about the muscular system.

This activity requires a little patience but turns out really awesome!

You will need:

-Construction paper

-A pencil

-Scissors

-A few plastic drinking straws

-Tape

-String

Start by tracing a hand, the bigger the better, so an adult hand is preferable. Next cut the hand out.

Cut the plastic straws into small pieces about 1/2 inch long.

Tape the straw pieces in a row down each finger. Try to fit 3 on each finger and 2 on the thumb. You can use a few longer sections to run down the hands to the wrist. Taping the pieces on is the part that requires a little patience. It can be a little hard to get them all in place.

Cut 5 lengths of string long enough to run down from the tips of the fingers to a few inches past the wrist.

Tape a string to the back if each finger tip. Pull the string over the tip of the finger and string it through the plastic straws running down that finger, then through the straw running to the wrist.

Once all the fingers are threaded, you can pull the strings to make the fingers bend open and closed!








Resources For Learning About The Muscular System:

-How Your Muscular System Works from TED-Ed is a video about how our muscles work to move our body parts.

-Biology For Kids: The Muscular System from Ducksters has lots of general information about muscles and the human muscular system.

-The Muscular System from Kids Biology has information about how muscles work and the different types of muscles.

-Label The Muscles Printable  from kidshealth.org

-Muscular System Word Find Printable from kidshealth.org

  1. Looks super fun! We did human body a few weeks ago. I'll have to try the bones in vinegar soon, though.

  2. Your Articulated Hand Activity is such a great idea! I am definitely going to try this one at home. Thank you for sharing!

Learning To Read Is Not A Race

So much emphasis is put on early literacy these days. Many school districts expect children to be reading by the end (or sometimes even the beginning) of kindergarten. While there is certainly nothing wrong with a child learning to read early, not all kids are developmentally ready to read at age 5, and that's okay. In this post I share several reasons why learning to read isn't a race.








Developmental Readiness
Kids all develop at their own pace. We know this when it comes to learning to walk, or climbing the jungle gym, or being ready for slumber parties, but it is often over looked when it comes to learning to read. Not all kids are developmentally there at the same age.  

Pushing kids to read before they're ready can cause a lot of frustration and resentment. It can destroy a child's chance to develop a love for reading by turning it into a frustrating chore. 


Reading Isn't The Only Way To Learn New Information
One of the reasons reading is pushed so early is to get k…

Make A Simple Compost Bin (a fun way to teach kids about soil)

We did a fun unit on soil last year and our big culminating project was setting up our own backyard compost bin. It ended up being much more simple to do than I originally thought it would be. In fact it's so simple, everyone should consider starting one! It's a great way to reduce your household waste, teach kids about soil and composting, and you end up with some excellent soil for your garden out of the process.




Setting Up A Compost Bin:
The first thing you need to do is pick a place for your bin. The best location will get a few hours of sun a day (the heat will help speed up the composting process) but not too much sun because you want your compost to stay moist. You also want to pick a spot somewhat close to the house so adding kitchen scraps is easy. 
Once you've chosen a location, it's time to actually set up your bin. Your compost bin can be as simple as just a pile in your yard (I personally don't use this method because we have too many critters around here…

5 Reasons To Let Your Kids Go Barefoot

I'm always surprised by how many concerned comments we get from well meaning strangers when my kids are barefoot in public. Comments like "Be careful, there are sharp rocks out here" or "Ouch, don't the wood chips hurt their feet?" I know these people mean well and are genuinely concerned but their concern is misplaced. Going barefoot has many benefits and wearing shoes too often can actually be damaging.


In this post I will share 5 ways going barefoot is beneficial for children (and adults too).




Proper Foot And Leg Development:
Wearing shoes affects the way a person steps. It requires using different sets of muscles differently than walking barefoot. Over time this can affect the development of the foot and leg muscles.
Modern shoes are constricting. Over time they can actually change the shape of a person's feet. Shoes can squish the bones of the feet together, affecting toe spread and arch. 
Flat feet are rare in places where shoes are seldom worn. Toe sp…

Six Fun Activities for Teaching Sight Word Recognition and Spelling

Sight words are words that you recognize by sight instead of sounding them out phonetically. Most of us do the vast majority of our reading by sight. When your reading a book you aren't sounding out words as you go, your reading by sight. You recognize the words because you've seen them many times before. The Dolche List is a list of the 315 most commonly used words in the English language. About 80% of the words in children's literature and 50% of the words in adult literature are compromised of these 315 words. Once a child has mastered these words, reading becomes much easier. In this post I'll share some of my favorite fun hands on sight word games and activities.


Flash card games:    We have several flash card games we like to play. Some of our favorites are Sight Word Go Fish and Sight Word memory. Making sight word flash cards is simple. I just write the sight words we're working on on 3 x 5 cards or even just rectangle pieces of construction paper. I don'…
