We have come to the end of our human body science topic. We enjoyed learning about the position and function of the skeleton and major organs of the human body. We used cotton buds and glue to create this skeleton artwork. The cotton buds represent the bones in the human body. Did you know there are 206 bones inside your body?💀
Once we explored the heart and the circulatory system, we focused on the lungs and the respiratory system; the group of organs and body tissues associated with breathing. We took part in different types of exercise to see the effect this would have on our breathing.
Next we used half a plastic bottle and balloons to make a model of the lungs. Have a look at the photos below.
The balloon at the bottom works like your diaphragm—a strong muscle that expands and contracts to cause your lungs to fill with air and then empty out again. The movement of the balloon matches your breathing – when you breathe in, your lungs fill with air just like the balloon inside the bottle did. That’s because the diaphragm expanded making room for air inside the lung. When you breathe out, your diaphragm contracts (or squeezes in) pushing all the air out of your lungs. 🎈🫁😮💨
Our science topic this term is the human body. We have been learning about the skeleton, bones, muscles and are now beginning to learn about the main organs in the human body. Recently we explored the heart. Your heart is sort of like a pump, or two pumps in one. The right side of your heart receives blood from the body and pumps it to the lungs. The left side of the heart does the exact opposite: It receives blood from the lungs and pumps it out to the body.
We filled up 3 two-litre bottles with red-coloured water to represent the quantity of blood in an average adult human. We passed the bottles around so we could feel their mass. Each bottle was around 2kg (6kg in total).
Next we used red and blue coloured play dough to make a model of the human heart. 🫀♥️
