Science Fun 5.Digestive System.

 My daughters gummy snake digestive system. 

We put tracing paper (lunch wrap) over top of a poster and used it as a guide.

Then using the poster and book as a guide she typed labels for each part of the digestive system.

It's pretty cool when after the lesson you get to digest it too!

Science Fun- Specialised Cells. The Goblet Cell.

The goblet cell is a specialized cell. It's purpose is to discharge mucus- aka SNOT and PHLEGM. Exciting stuff for a 13 year old boy and I had no trouble at all getting him actively involved!There are of course many specialized cells in the human body. I chose this one because it was boy friendly!

 Marshmallows represent the Goblet Cell. He used the small pink lollies to represent cilia as well as cells within the gel mucus. That was his idea and I am happy to improvise where needed!  The coloured lolly-sticks are pieces of mucus being discharged but shown in the varying colours mucus (yes the snot!) can come in.

 Icing made not only a good glue but a wonderful cell mucus. It is different to the mucus discharged by the goblet cell, it's more of a lubricant to keep everything working well.Again, my son's input!

 

 Next to the Goblet cells my son made a scale to show the different types of mucus which may end up on your tissue and what they mean in regards to your health.

Next science post is SNOT ROCKETS aka the SNEEZE. Check back soon if you want to see the results of our activities.

May your nest be blessed!

Science Fun- Alveloi, Bronchial Group and Gas Exchange

 We are having an amazing, productive week. I love it when things roll this way!

Above: The makings of a fabulous physiology session focusing on the respiratory system.

Below: Reconstruction of the bronchial group and alveloi. They are located inside the lung organ. 

You can click on any image to enlarge them.

 The large pink reconstruction shows large alevolar sac. Ironically the small pink lollies are called 'smokers.' I remember these from when I was a kid, they taste like aniseed but I am not sure how they got there name.

 The above photo shows airway tubes being affected by asthma and as it should look.

The photo below shows gas exchange taking place.

My son reconstructed the Goblet Cell, a specialised cell that discharges mucus, please check back soon to see the lesson :)

May your nest be blessed,
