In term 1, the grade 5 students learned about three different human systems in science and how these systems function to help our body regulate everyday. We started off the unit by talking about the digestive system, the respiratory system, and circulatory system.
In the circulatory system, we learned about the different parts of the heart and how the heart pumps blood to the rest of our body. In one of our lessons, we learned that there are 4 different components that make up blood (plasma, platelets, red blood cells, and white blood cells).
To demonstrate the four different components that make up blood, we had a fun science experiment where we made our own “blood”!
First, we added 4 drops of yellow food coloring and 1 tbsp of salt and sugar into the water which represented the plasma.
Then, we added red food coloring in a ziploc bag that contained star puff cereal which represented the platelets. Next, we added red food coloring in a ziploc bag that contained cheerios which represented the red blood cells.
Finally, we added marshmallows which represented the white blood cells. We then added all the ingredients to one container and mixed it all together to make blood!
The grade 5 students enjoyed this science experiment and had fun learning about the 4 different components that make up blood! Hope you enjoy these photos!
