The Grade 4s spent an exciting time investigating and discussing the importance of eggs - their structure and variety - both for reproduction and as a food source. The practical work was a highlight, especially for those who had not cracked an egg before! We tracked the dissolving of eggshell with an egg submerged in vinegar - the resulting rubbery shell-less eggs were of great interest.

Reflections: “What did you find most interesting and why?”

• looking under the microscope because it felt like I was in the

egg - Josephine Staples

• the chalazae because under the microscope they looked like

hair - Haidyn Govender

• the germinal disc because I always thought the yolk was the

chick - Rowan Shabne

• the vinegar egg because you could see the yolk bobbing

around - Lucy Snell

• the part where we got to open the egg and see what’s inside

because it’s fun to just have your own look instead of of

someone else telling you - Sophia Nienaber

• the parts of the egg because now when I crack an egg all the

parts of it and their names come straight into my head - Ella

Sproule

• the yolk because I didn’t know that’s how the baby ‘eats’ in

the shell - Pakane Kekana
