Happy Friday Friends!
Which of these animals eggs are you the most familiar with?
Do you have any eggs from a chicken in your home or on a nearby farm?
We see so many eggs in the springtime because they represent new birth and fresh life. All of the flowers and animals are waking up from the cold winter, blooming and having new babies.
Can anyone guess why birds lay eggs and don't carry their babies inside their bodies? Birds need to fly, and if they get too heavy, they wouldn't be able to make it off the ground!
Eggs need a lot of warmth in order for the embryo (baby chick) to develop, so the mama hen sits on her eggs to help them grow safely. This is called incubation!
What's beneath the shell?
The inner and outer membranes, found between the eggshell and the egg white, keep bacteria from entering the egg, and help to slow evaporation of moisture from the egg.
The air cell, located between the inner and outer membranes at the large end of the egg, holds oxygen for the chick to breathe.
The albumen, or the egg white, cushions the egg yolk floating within it and is the main source of protein and water for the embryo.
The yolk provides food for the embryo. It is made up of fats, carbohydrates, proteins, vitamins, and minerals.
The chalazae are cords on two sides of the yolk that keep the yolk floating in the center of the albumen.
The germinal disc is the white spot on the yolk. This is where the female’s genetic material is found.
Nature Easter Eggs!
This time of year there are many spring holidays, like Easter! There is a spring tradition to decorate Easter eggs with paint or food dye. Today, we will decorate them with nature!
Here's what you will need:
- Cardboard or card stock (try using an old tissue box)
- Glue sticks or white glue
Collect all of your supplies! For your nature supplies, you can go outside and gather some small flowers, grass, leaves, rocks ... whatever you can find!
Trace different size egg shapes on your cardboard. Try to make some big ones and little ones! Use your scissors to carefully cut out the egg shapes.
Make a design on your egg with the pieces of nature you found outside!
Try making patterns or layering your nature pieces. Add more glue as you need it!
