Science for 12 Year Olds
7th Grade • Seventh graders are developing abstract thinking and tackling pre-algebra and complex literary analysis.
At age 12, children are ready for exciting new science concepts. This guide covers curriculum milestones, fun activities, and tips to make learning enjoyable.
What 12 Year Olds Learn in Science
Typical curriculum milestones for 7th Grade
- Develop and use a model to describe the structure of atoms and the periodic table
- Analyze and interpret data to determine the substances involved in chemical reactions
- Construct explanations based on evidence about how organisms are classified
- Apply scientific principles to design, evaluate, and refine a device for thermal energy transfer
- Construct scientific explanations using evidence for how environmental factors affect growth
- Develop a model to describe the cycling of Earth's materials and the flow of energy
- Gather, read, and synthesize information from multiple sources to support scientific claims
Science Activities for 12 Year Olds
Fun, hands-on activities to practice science at home
Atomic Model Timeline
Research the history of atomic models from Democritus to modern quantum models. Create a timeline showing how scientific understanding has evolved with new evidence.
Chemical Reaction Investigation
Conduct safe chemical reaction experiments (baking soda and vinegar, milk and vinegar for plastic). Observe evidence of reactions and identify reactants and products.
Organism Classification Challenge
Collect or photograph local organisms. Use classification keys to identify them and place them in taxonomic groups. Create your own classification key for a set of objects.
Thermal Device Engineering
Design and build a device to keep a cup of water hot (or cold) for the longest time. Apply knowledge of thermal energy transfer. Test, collect data, and refine your design.
Tips for Teaching Science
Practical advice from educators and parents
Encourage scientific literacy by discussing science news and discoveries
