It delves into the properties of solids, liquids, and gases using particle theory, temperature as a kinetic energy measure, changes of state, and diffusion. The water cycle is dissected with an emphasis on evaporation, condensation, precipitation, and factors influencing evaporation rates. Students also investigate the impact of temperature on solubility. pH and salinity are introduced with a focus on elements, compounds, and mixtures, alongside an in-depth look at seawater composition. Factors affecting salinity, including erosion, run-off, precipitation, evaporation, and temperature, are explored, alongside a comparison of salinities in the Pacific Ocean, Baltic Sea, and Red Sea. We will also look at estuaries as tidal bodies where freshwater and seawater intermingle, causing salinity fluctuations. L/O: Introduction to Seawater Describe the properties of solids, liquids, and gases using particle theory. Explain temperature as a measure of kinetic energy in particles (°C). Define and explain changes of state (evaporation, condensation, freezing, and melting). Describe energy changes during changes of state. Explain diffusion using particle theory. Conduct a practical investigation on the effect of ice melting on sea level. The Water Cycle. Interpret and describe the water cycle, focusing on evaporation, condensation, precipitation, and surface run-off. Discuss factors affecting the rate of evaporation from oceans. Investigate the effect of temperature on solubility of a solute in water. Salinity. Use and explain the terms element, compound, and mixture. Define and describe elements
