3D Shapes in the Environment
Investigate how 2D nets fold to form 3D shapes and design nets for simple solids.
Key Questions
- What 3D shapes can you spot in the classroom or at home?
- How are a cone and a cylinder the same, and how are they different?
- Can you sort a collection of 3D shapes into groups that roll and groups that do not roll?

About This Topic
Magnetism introduces students to the 'invisible pull' of magnetic force. In the NCCA Science curriculum, this is a fascinating part of the 'Energy and Forces' strand. 1st Class students explore which materials are magnetic and which are not, discovering that while many magnetic items are metal, not all metals are magnetic. They also learn about the two poles of a magnet, North and South, and the concepts of attraction and repulsion.
This topic is ideal for developing the 'Working Scientifically' skills of predicting and testing. The 'magic' of magnets moving objects through paper or water captures children's imagination and prompts them to ask 'how?'. It also has practical links to everyday technology, from fridge magnets to compasses. Students grasp this concept faster through hands-on 'magnet hunts' and collaborative problem-solving tasks where they must use magnets to complete a challenge.
Active Learning Ideas
Inquiry Circle: The Magnet Hunt
Pairs are given a magnet and a clipboard. They explore the classroom to find 5 things the magnet sticks to and 5 things it doesn't. They must look closely at the materials (e.g., 'It sticks to the chair leg but not the seat') and record their findings.
Simulation Game: Magnetic Bumper Cars
In small groups, students use two bar magnets. They try to bring the ends together. They experience the 'invisible wall' of repulsion (North to North) and the 'snap' of attraction (North to South), acting out the 'push' and 'pull' they feel.
Inquiry Circle: The Paperclip Rescue
Place paperclips at the bottom of a jar of water. Students must use a magnet on the *outside* of the glass to 'walk' the paperclip up and out of the jar without getting their hands wet. This demonstrates that magnetic force can travel through materials.
Watch Out for These Misconceptions
Common MisconceptionAll metals are magnetic.
What to Teach Instead
This is very common. Provide copper coins (2c/5c), aluminum foil, and steel paperclips. Through a 'Station Rotation' test, students will see that the magnet only likes the steel, helping them realize that 'metal' is a big group and only some are magnetic.
Common MisconceptionBig magnets are always stronger than small magnets.
What to Teach Instead
Children often equate size with strength. Provide a large, weak fridge magnet and a tiny, strong neodymium magnet. Have students test how many paperclips each can pick up to prove that 'strength' depends on the magnet type, not just its size.

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 plannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
rubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
