Slide Deck

Fluid Facts

Discover how water powers your body and why staying hydrated matters!

Welcome students! Introduce today’s topic: the importance of water in our bodies and how it fuels our daily activities. Tell them they’ll learn key facts and later reflect on their own hydration habits.

Why Hydration Matters

• Supports physical performance
• Helps cognitive function
• Regulates body temperature

Explain each point: hydration supports muscles during exercise, boosts brain function during classwork, and helps regulate temperature when we’re active.

Body Composition: Water in You

• Our bodies are about 60% water on average
• Muscles and brain: ~75% water
• Bones: ~31% water

Ask students to guess what percentage of their bodies is water before revealing the numbers. Emphasize that different organs have different water content.

Signs of Dehydration

• Thirst and dry mouth
• Fatigue, dizziness, or lightheadedness
• Headaches and dark-colored urine

Describe common dehydration symptoms and invite students to share if they’ve ever experienced any of these during sports or hot days.

Benefits of Staying Hydrated

• Improves energy levels and mood
• Boosts concentration and mental clarity
• Aids digestion and nutrient transport

Link these benefits back to school and sports: staying hydrated can help them focus better in class and perform stronger on the field.

Quick Reflection

Think-Pair-Share:
When did you last feel thirsty?
How did it affect your performance or mood?

Have students think silently for 30 seconds, then pair up to share their answers. After 1–2 minutes, invite a few pairs to report back.

Answer Key

Daily Water Log Answer Key

This answer key provides grading guidelines and exemplar responses to help teachers evaluate students’ Daily Water Log Worksheet entries. Because logs and reflections are subjective, use the rubric below to assess completeness, realism, and depth of student responses.


1. Daily Hydration Goal (3 points)

Expectations:

  • Student sets a realistic target based on general recommendations (about 6–10 cups or 1500–2500 mL).
  • Goal is clearly stated in cups and/or milliliters.

Scoring Rubric:
• 3 pts – Goal is within recommended range (6–10 cups / 1500–2500 mL) and properly labeled.
• 2 pts – Goal is slightly outside the range (e.g., 4–5 cups or 11–12 cups) but shows understanding.
• 1 pt – Goal is unrealistic (e.g., 1 cup or 20 cups) or missing units.


2. Water Intake Log (4 points)

Expectations:

  • At least 5–6 entries spanning morning, mid-day, and afternoon.
  • Amounts cumulatively approach the student’s stated goal.
  • Notes reflect context (e.g., “after PE,” “felt thirsty,” “during math class”).

Scoring Rubric:
• 4 pts – 6+ entries, appropriate amounts, and meaningful notes for each.
• 3 pts – 4–5 entries, reasonable amounts, and some notes.
• 2 pts – 2–3 entries or missing context in notes.
• 1 pt – Fewer than 2 entries or no contextual notes.


3. Reflection Questions (3 questions, 3 points each)

Question 1

Did you meet your hydration goal for today? Why or why not?

Expectations:

  • Clear Yes or No answer.
  • A specific reason (e.g., forgetfulness, busy schedule, used reminders).

Exemplars:

  • “Yes—I hit 8 cups because I refilled my bottle at lunch and used an alarm every hour.”
  • “No—I only drank 4 cups since I forgot my water bottle; next time I’ll keep one on my desk.”

Scoring (3 pts):
• 3 pts – Direct answer and specific reason.
• 2 pts – Answer given but reason is vague (“I was busy”).
• 1 pt – Neither clear answer nor reason.


Question 2

What strategies or reminders helped you drink water throughout the day?

Expectations:

  • At least two concrete strategies (e.g., alarms, buddy system, visible bottle).

Exemplars:

  • “I set my phone alarm every hour and put a sticky note on my binder.”
  • “My friend and I did a quick check-in at lunch to make sure we both had water.”

Scoring (3 pts):
• 3 pts – Two or more detailed strategies.
• 2 pts – One solid strategy or two very basic ones.
• 1 pt – No clear strategies listed.


Question 3

What barriers or challenges did you face in staying hydrated? How could you overcome them tomorrow?

Expectations:

  • Identification of at least one barrier (e.g., forgetting, taste, busy periods).
  • A realistic solution or plan to address it.

Exemplars:

  • “Barrier: I forgot during after-school club. Fix: I’ll drink before club and set a watch alarm.”
  • “Barrier: Plain water bored me. Fix: I’ll add lemon slices or use a fun water bottle.”

Scoring (3 pts):
• 3 pts – Specific barrier plus practical solution.
• 2 pts – Barrier noted but solution is vague.
• 1 pt – Barrier or solution missing or unclear.


4. Overall Completion & Effort (Up to 2 bonus points)

  • +1 pt for neatness and legible handwriting.
  • +1 pt for extra reflections (e.g., mood changes, energy levels beyond required fields).

Grading Summary

  • Daily Hydration Goal: 3 pts
  • Water Intake Log: 4 pts
  • Reflection Q1: 3 pts
  • Reflection Q2: 3 pts
  • Reflection Q3: 3 pts
  • Bonus Completion/Effort: 2 pts

Total Possible: 18 points
