Science is a process of inquiry that involves questioning, experimenting, and exploring the natural world.

Exploration allows us to perform experiments and observe, helping us to develop a deeper understanding of the environment.

Properties of materials are characteristics that describe how materials behave, like hardness, flexibility, and conductivity.

Metals are typically shiny, conductive, and malleable, while non-metals are dull, insulative, and brittle.

A reversible change is one that can be undone, like freezing and melting of water.

Heat can cause changes in state, such as melting and boiling, affecting how materials behave.

The water cycle is the continuous process of evaporation, condensation, and precipitation of water.

Essential life processes include growth, reproduction, respiration, and nutrition.

Plants produce their food through photosynthesis, using sunlight, carbon dioxide, and water.

Early humans used the shadows of objects in the sunlight to tell the time of day.

Light travels in straight lines and can be reflected, refracted, and absorbed.

An eclipse occurs when one celestial body moves into the shadow of another body, like the Earth or Moon.

Earth rotates around its axis, which causes day and night.

Gravity is the force that attracts objects towards each other, keeping planets in orbit.

Scientific inquiry is the process of asking questions, developing hypotheses, and conducting experiments to find answers.

Sustainability refers to practices that do not deplete resources and consider long-term environmental health.

Curiosity drives scientists to ask questions, explore new ideas, and make discoveries.

Experiments help test hypotheses and gather data to support or refute scientific ideas.

Scientific responsibility involves considering the impact of scientific work on society and the environment.
