Exploring Water: Understanding Its Structure and Properties in Marine Science

Water is fundamental to life on Earth, especially in marine ecosystems where it shapes environments and influences biological processes. Understanding the intricate properties of water begins with delving into its changes of state, the structure of its molecules at the atomic level, and the unique bonds that hold them together. In this lesson, we’ll explore these concepts to grasp how water’s chemistry underpins its vital role in marine science.

Lesson Outline

• Begin with Bell Ringer Day#1
• PowerPoint/ Lecture/Notes (PPT – slides 1- 11)
  • Explain the three states of water (solid, liquid, gas) and the conditions that cause transitions between these states (temperature and pressure changes).
  • Briefly review the structure of atoms, focusing on protons, neutrons, and electrons.
  • Explain the atomic structure of water molecules (one oxygen atom and two hydrogen atoms), emphasizing how covalent bonds form between them.
  • Define covalent bonding and describe how it occurs in a water molecule, with oxygen sharing electrons with hydrogen atoms.
  • Use diagrams or models to illustrate the covalent bonds in a water molecule. Allow students to ask questions for clarification.
  • Differentiate between ionic and hydrogen bonds. Discuss their roles in water chemistry and their significance in marine environments.
  • Provide examples of ionic compounds in seawater and how hydrogen bonds contribute to water’s unique properties.
  • Explain how hydrogen bonding influences water’s properties such as cohesion, surface tension, high specific heat, and expansion upon freezing.

This short video, curtesy to TED-Ed is a great visual explaining how atoms bond.

• Use Guided Notes – This year, I’m using Version B Guided Notes with my students, as I’ve noticed they benefit from having more structured support during class.
  • It features fill-in-the-blank prompts for key vocabulary and concepts, making notetaking faster and more accessible, especially for English language learners or those with processing difficulties.
• Small group activity –Review/Practice/Quiz 1.1 Particle theory and bonding
  • Students work in small groups and answer Exam Style Questions
  • Have students share their answers with the class.
  • Correct any misconceptions.

This lesson plan equips students with a comprehensive understanding of water’s fundamental properties in marine science, preparing them to explore further topics in AICE Marine Science.

Homework – high level/flipped classroom

• Version A – For High-Level Students:
  Ideal for independent or advanced learners, this version requires students to copy all notes by hand as homework before class. This flipped-learning approach helps students come to class prepared, freeing up time for application activities, discussions, and AICE-style practice questions.
• For this assignment have students fill in the blanks using the PPT Presentation.
