Science is FUN!

In my form 2 class we are currently studying gaseous exchange. Last week we learned about the respiratory system in insects and after talking in class about spiracles we went out into the field and caught grasshoppers so the students could observe the spiracles in action. This week we learned about gaseous exchange in fish and in amphibians. So we did a lab where the students cut out the gills of fish to observe them and we also went on a "frog safari" where we caught frogs so we could observe them breathing (mostly the movement of the buccal cavity). Here are some pictures, proof that science in fun!

On our "frog safari" we were able to catch a few frogs and the girls got to observe the way the floor for the frogs mouth moves up and down to facilitate inhalation and exhalation.

Prime "frog safari" terrain was around the taps from the water storage tanks

The girls in the lab awaiting the lab instructions. These are my form 2 students, you may notice Diana, an albino student who joined Bande Girls' this year. I'll be talking more about her in an upcoming blog.

Showing my students where the operculum is located and how to remove it to expose the gills

Observing the gills in water to see how the differ than when observed out of the water

Checking to see if the skin of frogs is really moist and thin like I told them it was for gaseous exchange to take place
Frog safari success!
