Gravity: The Invisible Pull
Students will explore the concept of gravity as a force that pulls objects towards the Earth.
Key Questions
- Analyze the effect of gravity on falling objects.
- Compare the fall rates of objects with different masses (ignoring air resistance).
- Predict what would happen if gravity suddenly disappeared.
NCCA Curriculum Specifications
About This Topic
The Human Figure in Motion takes students from drawing 'stick men' to understanding the 3D mechanics of the human body. In 3rd Class, students use wire, pipe cleaners, or cardboard armatures to create figures that can run, jump, or dance. This topic focuses on the NCCA Construction and Drawing strands, emphasizing 'Visual Awareness' of proportion and the way joints allow for movement. By building a 'skeleton' first, students learn how the body is structured before they add 'flesh' or clothing.
This topic is highly kinesthetic. It encourages students to use their own bodies as a reference point. Students grasp this concept faster through role play and peer observation, where they freeze in an 'action pose' for their partner to study and replicate in wire.
Active Learning Ideas
Role Play: The Human Mannequin
One student acts as a 'statue' in a dynamic pose (e.g., kicking a ball). Their partner uses pipe cleaners to quickly 'sketch' the angles of the limbs and the tilt of the head.
Inquiry Circle: The Balance Point
In small groups, students try to make their wire figures stand up on their own in an active pose. They must discuss where the 'center of gravity' is and how to use a base to support the weight.
Gallery Walk: Olympic Statues
Display all the figures in a 'stadium' setting. Students walk around and try to identify the specific sport or action each figure is performing based only on its pose.
Watch Out for These Misconceptions
Common MisconceptionArms and legs come out of the head or the very bottom of the body.
What to Teach Instead
Students often struggle with where limbs attach. Hands-on modeling with 'jointed' cardboard puppets helps them see that arms attach at the shoulders and legs at the hips.
Common MisconceptionLimbs are straight lines that don't bend in the middle.
What to Teach Instead
Many 3rd Class drawings lack elbows and knees. Role-playing 'robot' vs. 'human' movement helps them identify exactly where the body hinges.

Planning templates for Curious Investigators: Exploring Our World
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
rubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
