Science for 13 Year Olds

8th Grade • Eighth graders are preparing for high school with advanced academics and developing personal identity.

At age 13, children are ready for exciting new science concepts. This guide covers curriculum milestones, fun activities, and tips to make learning enjoyable.

What 13 Year Olds Learn in Science

Typical curriculum milestones for 8th Grade

  • Analyze and interpret data to determine similarities and differences in structure across organisms
  • Construct explanations for how natural selection leads to increases in beneficial traits
  • Use argument supported by evidence for how body systems interact to maintain homeostasis
  • Develop and use models to describe the role of gravity in motions within galaxies and the solar system
  • Analyze and interpret data to determine relationships among kinetic energy, mass, and speed
  • Construct explanations about how potential and kinetic energy are related
  • Apply scientific principles to design, construct, and test a device that minimizes or maximizes energy transfer

Science Activities for 13 Year Olds

Fun, hands-on activities to practice science at home

1

Natural Selection Simulation

Simulate natural selection using colored objects in different environments. Track which "organisms" survive based on camouflage. Analyze data and explain results in terms of natural selection.

Materials: Colored objects (beads, paper clips), Various colored backgrounds, Data collection sheets, Timer
2

Energy Transformation Coaster

Build a marble coaster and analyze energy transformations. Measure height and speed at different points. Calculate potential and kinetic energy and explain conversions.

Materials: Foam tubes, cardboard, or track-building materials, Marbles, Ruler, Stopwatch, Calculator
3

Body Systems Interaction Investigation

Research how body systems work together during a specific activity (running, eating, sleeping). Create a diagram showing system interactions and feedback loops that maintain homeostasis.

Materials: Research sources, Large paper for diagram, Markers, Body systems reference
4

Gravity and Motion Model

Create a model or simulation demonstrating how gravity affects objects in the solar system. Explain orbital motion, why the moon stays in orbit, and what would happen without gravity.

Materials: Model-building supplies, Simulation software (optional), Presentation materials

Tips for Teaching Science
