Exploring Body Systems

Grade 3 students have been busy investigating the fascinating systems that help our bodies function every day. Using microscopes, students worked hard to independently prepare, adjust, and manage their own slides. With patience and careful observation, they were able to view different types of cells, including red blood cells, muscle cells, and nerve cells. It was wonderful to see their confidence grow as they made small adjustments to bring their samples into clear focus.
We also explored the muscular system. Students identified different types of muscles and learned about their basic functions, including how muscles help us move, support our posture, and carry out important actions inside the body. During a short hands-on investigation, students examined the muscles and bones of a chicken to observe how muscles attach to bones and work together to create movement.
Our inquiry then moved to the respiratory system. Students learned about its different parts and the role each one plays in breathing. They were able to explain how respiration happens and how oxygen enters the body while carbon dioxide leaves it. Most recently, we have begun investigating the connections between body systems. Students have found strong evidence that systems do not work alone—for example, the respiratory system brings oxygen into the body, while the circulatory system carries that oxygen to cells where it is needed. We look forward to continuing this inquiry as students deepen their understanding of how the human body works as an interconnected whole.

Grade 3 Body Detectives: Mapping Our Amazing Body Systems

Image
This week, our Grade scientists began exploring the amazing systems inside the human body! To share what they already knew, students worked in teams to investigate the respiratory, circulatory, and skeletal systems. Each group created a giant human-body poster by tracing the outline of one of their teammates on a large sheet of paper. Then, they filled the outline with drawings of the body parts they thought helped their assigned system do its job. There was plenty of lively discussion, creative thinking, and teamwork as students shared ideas and turned their posters into fantastic “body maps”! This hands-on activity helped us discover what students already understand about body systems, as well as some ideas we will investigate further. As our inquiry continues, students will become curious body detectives—asking questions, testing their thinking, and uncovering the facts about how their amazing bodies work.

Our First 2 Days in Third Grade

Image
This week, Grade 3 students kicked off the school year by building community and settling into new routines. They met classmates and teachers, learned the updated timetable, and discussed changes for the year. In small groups, students co-created essential classroom agreements, then reviewed and approved peers’ suggestions together. They also explored the idea of being lifelong learners and linked it to key learner attributes: knowledgeable, thinker, caring, reflective, inquirer, open-minded, risk-taker, principled, balanced, and communicator. Working in teams, they designed simple but meaningful posters for each attribute to show what it looks like in everyday school life. For their first unit task, students examined pictures of different body organs and identified relationships between them. They demonstrated these connections by drawing lines between pairs of organs that are related. All in all, it was a busy and engaging first two days back at school.

Inside the Body: Grade 3's Skeletal System Adventure

Image
What a fantastic week of science learning in Grade 3! Our students became skeleton scientists as they explored the amazing framework inside the human body. First, they put their knowledge to the test by cutting out different bones and working out where each one belongs in a human skeleton. Students carefully arranged and glued the bones onto paper, showing great teamwork, curiosity, and growing confidence. Next, pairs of students became bone experts! Each team investigated the shape and job of one type of bone, then created a simple poster to teach their classmates what they had discovered. We were so impressed by the thoughtful research and enthusiastic sharing. Our scientists also returned to the questions they had asked about bones. They highlighted the questions that our class activities had not yet answered, then worked in pairs to research them independently. Students proudly shared their discoveries with the class, helping everyone learn something new. We also explored how...
