Bones, Muscles, Hearts, and Lungs: Learning About Our Bodies

Grade 3 students are now in the final week of their unit exploring the form and function of body systems and the important ways these systems connect to help our bodies work. To demonstrate their understanding, students chose one body system they already felt familiar with or were especially interested in learning more about. Based on their shared interests, they worked collaboratively in pairs and small groups to investigate their chosen system. Their goal was to explain the form and function of the body system and share their learning through a creative presentation. Students could choose to create an informative poster, record a voice presentation, or make a video. Many students were fascinated by the skeletal system and chose to learn more about how bones support, protect, and help the body move. The muscular, circulatory, and respiratory systems were also represented, giving the class a wide range of body systems to explore. After completing their presentations, the Grade 3 students worked in pairs to discuss a “What happens if…?” scenario they had chosen. They considered the possible effects on the body when a system does not work as expected, such as when a person experiences an injury, illness, or other health concern. This assessment gave students an opportunity to apply their knowledge beyond one body system. They were encouraged to make connections between the skeletal, muscular, circulatory, and respiratory systems and explain how these systems work together to respond to different situations our bodies may encounter. Through these learning experiences, students strengthened their research, communication, collaboration, and critical-thinking skills while developing a deeper appreciation for the remarkable systems that keep our bodies healthy and active.

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...
