Grade 4 | Our Amazing Human Body Systems

By Mrs. Sara Ashley Yurosko

“Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own; you were bought at a price. Therefore, honor God with your bodies.” 1 Corinthians 6:19-20

This quarter we had the awesome opportunity to learn about our bodies. We broke our bodies down into 5 major systems! These systems are interdependent and rely on each other to work well. Our Summative helped us to dig deeper into one system and the way it interacts with other systems. We also learned how we can take care of our bodies to ensure we are glorifying God. We want to share with you some of the activities we did and the things we learned.

The Digestive System

Julianne

We had so much fun learning about the digestive system. We made clay models of the organs and used bananas and crackers to illustrate how food works its way through the digestive system. The Respiratory System Our study of the respiratory system focused more on our responsibility to make sure to stay active and keep our respiratory system healthy.

The Skeletal System

Our good friend Mr. Bones helped us to understand the importance of all the bones and why they all look so different. We learned about how our Creator was so purposeful in His design of our skeletal system. Our responsibility is to make sure to feed and exercise our bodies to grow strong bones while we are young.

The Muscular System

We learned how the muscle fibers slide across each other to contract our muscles. We also learned why every muscle has an antagonist that helps to pull the other way. Exercise is super important for muscles to keep them healthy and strong.

The Circulatory System

We learned that our circulatory system is the highway for nutrients, gases, and waste through our body. We also learned that the heart has 4 chambers and why each of them is important. Our experiment showed us how the chambers of the heart pump blood around the body.

Students’ Reflections:

Marietta Gascon Nuñez

To keep my digestive system healthy, I need to be careful with the calories that I eat. I need to eat more fruits and vegetables. Drinking a lot of water is also important for my digestive system to work well. I need to try to eat less sugar and salt. It is better to drink more water than soda. I also need to wait for my stomach to process the food and to let it digest well. -Marietta Gascon Nuñez

One of the body systems that I have learned is the muscular system. One new idea that I have learned from the muscular system is how we should take care of my muscular system. After I learned about this system, I have decided to limit my screen time by not watching any videos during the break times. Instead, it would be better for me to walk around the house or do some exercise. This will help my muscles to be healthier. Healthy muscles can make my body strong. -Saoloan Donahue Jonatan Sitanggang
