The Naked Egg Experiment

In this post I will share how to do one of mine and my daughter's all time favorite experiments, making naked eggs! It's really simple but the results are so neat!

The Naked Egg Experiment- from The Barefoot Mom

For this experiment you will need:
-An egg
-A cup
-A few cups of vinegar (we used white vinegar)

Making A Naked Egg:

Start by placing the egg in the cup and add vinegar until the egg is fully covered.  Almost right away you should notice a reaction taking place. If you look closely you will see tiny bubbles forming around your egg. This is carbon dioxide forming from the reaction between the vinegar's acetic acid and the calcium carbonate that makes up the egg shell. 

Acetic Acid + Calcium Cabonate = Calcium Acetate + Carbon Dioxide+ Water

(This is the same reaction that happens with the acid test in my Mineral Identification Experiment)

Naked Egg Experiment:  from The Barefoot Mom

Leave the egg in the vinegar overnight. In the morning carefully change out the vinegar in your cup for fresh vinegar. If you use a brown egg, like we did, you will notice a lot of the brown color has dissolved away overnight. You will also notice that your egg's shell is becoming squishy.

Now comes the being patient part. Let your egg sit in the vinegar for another 1-2 days, until the shell has completely disappeared and all that is left holding your egg together is a transparent membrane. You may have to gently rinse under water to get the remains of the shell off. Be careful not to pop the membrane though!

Take a look at your egg in good sunlight or try shining a flashlight through it. You should be able to see the yolk inside!

Use this an opportunity to learn about egg anatomy. The Accidental Scientist has some good information here.

A Fun Spin On This Experiment - Bouncing Eggs:

Try this fun spin on the naked egg experiment! Soak several eggs in vinegar for 24 hours. The shells should be good and squishy by then. Then try dropping eggs from varying heights to see how high you have to drop it from to make the membrane burst. This is a messy experiment so you'll probably want to set it up outside.

  1. How fun! I cannot wait to do this with my oldest. We are always looking for science experiments to do!

  2. This looks awesome! Can’t wait to try it out!

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 ReadinessKids all develop at their own pace. We know this when it comes to learning to walk, or climb 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 InformationOne of the reasons reading is pushed so early, is to get kid…

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…

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


-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 int…

Water Relay Races For Kids

I don't know about your kids, but mine absolutely love games involving water and getting wet in the summer time.
In this post I will share 5 of our favorite water relay races to play with friends. These are perfect for birthday parties, homeschool get togethers, and other group events.

Sponge Relay:
For this relay you will need:
-2 teams of several kids each
-2 large sponges
-4 small buckets or containers of some sort
Divide your participants into 2 teams and have each team line up single file at a predetermined starting place. 
Hand out a sponge to the first participant in each line. Set a bucket of water by each team. Set an empty bucket about 20 ft away from each team. 
The two empty buckets should be the same size and should have a "fill line" marked half way up.
On a count of 3 (or ready set go) the first participant in each line should dip their sponge in the bucket of water, run to the empty bucket, squeeze the water from their sponge, then run back, hand off the sponge to…

40 Things To Look At Under A Microscope

Microscopes are an awesome scientific instrument that all kids should get a chance to learn how to use. There are so many everyday things that look amazing under a microscope. Under a microscope you can see that many objects that appear solid are actually made up of tiny parts, and that even plants and animals are made of tiny intricate parts. The microscopic world is amazing! In this post I share 40 things to try looking at, up close, under a microscope.

40 Things To Look At Under A Microscope:
1. A feather 

2. Soil

3. An insect wing

4. A human hair

5. An animal hair

6. Pond water

7. Diatomacious earth-  diatomacious earth looks SO cool magnified!

8. Cheek swab

9. An insect leg

10. A drop of blood

11. Mold

12. Sand

13. A shaving from a chicken bone- try both a piece of hard bone from the outside and some spongy bone from inside a bone.

14. Kombucha

15. Snake or lizard skin after they shed 

16. A flower petal

17. A sliver of wood

18. Sugar
