   Calculation:

   Answer: __ cups of flour

2. If you only have 5 cups of chocolate chips left, what is the maximum number of cookies you can make while keeping the recipe proportional?

   Calculation:

   Answer: __ cookies

Station 2: English (Figurative Language)

Read the short descriptive passage below, then identify the types of figurative language used.

The old house stood as a silent guardian on top of the hill. When the wind blew, the screen door groaned like an ancient beast. Inside, the dust lay thick on the floor, a blanket of forgotten memories. I had told my brother a million times not to go inside, but curiosity pulled him toward the door.

Match the figurative language device from the box to the correct example from the passage.

Devices: Simile, Metaphor, Personification, Hyperbole

1. "The old house stood as a silent guardian..." Device: ____

2. "...the screen door groaned like an ancient beast." Device: ____

3. "...a blanket of forgotten memories." Device: ____

4. "I had told my brother a million times..." Device: ____

Station 3: Science (Ecology & Energy Transfer)

In an ecosystem, energy flows from producers up to apex predators. However, only about 10% of the energy at one trophic level is passed on to the next level (this is known as the 10% Rule).

Imagine a meadow ecosystem with the following food chain: Grass (Producer) → Grasshopper (Primary Consumer) → Frog (Secondary Consumer) → Hawk (Tertiary Consumer)

1. If the grass in the meadow produces 20,000 kilocalories (kcal) of energy through photosynthesis, calculate how much energy is available to each level:

   • Grasshopper (Primary Consumer): ___ kcal
   • Frog (Secondary Consumer): ___ kcal
   • Hawk (Tertiary Consumer): ___ kcal

2. Explain what happens to the other 90% of the energy that is not passed up to the next level.

Station 4: History (Evaluating Evidence)

Historians use primary and secondary sources to reconstruct past events.

• Primary Source: An firsthand, eyewitness account or object from the time period.

2. A chapter about Ancient Rome in your current history textbook. Source Type: ____

3. A bronze coin minted during the reign of Julius Caesar. Source Type: ____

4. A biography of Amelia Earhart written by a historian in 2015. Source Type: ____

   Answer: ____

2. If you sail directly south from the United States and cross the Equator, which hemisphere are you entering (Northern or Southern)?

   Answer: ____

3. What is the name of the imaginary line of longitude located at 0° that divides the Eastern and Western hemispheres?

   Answer: ____

Station 6: Chess (Tactical Vision)

In chess, recognizing patterns is key to victory. Define the following tactical motifs and identify the piece that can jump over other pieces.

1. The Fork: Explain what a fork tactic is in your own words.

2. The Pin: Describe how a piece becomes "pinned" to a more valuable piece behind it.

3. Which chess piece is the only one capable of jumping directly over other friendly or enemy pieces?

   Answer: ____

Station 7: Music (Rhythm Arithmetic)

In music theory, different notes have different beat values in standard (4/4) time. Use the values below to solve the rhythm equations!

• Whole Note = 4 beats
• Half Note = 2 beats
• Quarter Note = 1 beat
• Eighth Note = 0.5 beats

Solve the math equations below by writing the total number of beats:

1. Quarter Note + Half Note + Quarter Note = ____ beats

2. Whole Note + Half Note + Eighth Note + Eighth Note = ____ beats

3. (2 x Half Notes) - (2 x Eighth Notes) = ____ beats

Station 8: Physical Education (Fitness Foundations)

To maintain physical fitness, we must train different components of the body. Match the fitness component with its correct real-world exercise.

Components: Cardiovascular Endurance, Muscular Strength, Flexibility, Body Composition

1. Holding a deep hamstring stretch for 30 seconds. Component: ____

2. Going for a continuous 3-mile run around the local park. Component: ____

3. Lifting a heavy barbell off the ground for 3 repetitions. Component: ____

Station 9: Art (Color and Perspective)

Artists use visual systems to create the illusion of depth and emotion on a flat canvas.

1. Color Theory: What is the term for two colors that sit directly opposite each other on the color wheel (e.g., blue and orange, red and green) and create high contrast when placed side-by-side?

   Answer: ____ colors

2. Perspective: In one-point perspective drawing, what is the name of the single point on the horizon line where all parallel lines seem to converge and disappear?

   Answer: The ____ point

Station 10: Life Skills (Budgeting Basics)

Imagine you earn an allowance of $100.00 per month from doing household chores and helping neighbors.

Review the expense items below. Classify each item as a Need (essential for survival/school) or a Want (discretionary/fun), then write a specific strategy on how you could save money on that item.

Budget Reflection: If you bought all 5 items listed above, your total spend would be $117.00. How would you adjust your spending to stay under your $100.00 budget while still getting your school notebooks?

Grand Champion Challenge (Optional Extension)

Choose two of the subjects from this worksheet and combine them to create a mini-project idea! Example: (Art + Science) Draw an anatomically correct diagram of a frog to show how its muscle structure helps it jump.

• My Two Subjects: and
• My Project Idea:

Answer Key

Station 1: Math

1. 9 cups of flour. (72 cookies / 24 cookies = 3. Scale factor is 3. 3 cups of flour x 3 = 9 cups).
2. 60 cookies. (5 cups of chips / 2 cups of chips per batch = 2.5 batches. 2.5 batches x 24 cookies = 60 cookies).

Station 2: English

1. Personification (treating the house as a guardian)
2. Simile (comparing the door groan to a beast using "like")
3. Metaphor (direct comparison of dust to a blanket)
4. Hyperbole (exaggerating "a million times")

Station 3: Science

1. Grasshopper: 2,000 kcal; Frog: 200 kcal; Hawk: 20 kcal.
2. The other 90% is lost to the environment as heat, used by the organism for cellular respiration/metabolic processes, or lost as waste.

Station 4: History

2. Secondary
3. Primary
4. Secondary

Station 5: Social Studies

2. The Pin: An attack on a piece that cannot move without exposing a more valuable piece behind it to capture.
3. Knight

Station 7: Music

1. 4 beats (1 + 2 + 1)
2. 7 beats (4 + 2 + 0.5 + 0.5)
3. 3 beats ((2 x 2) - (2 x 0.5) = 4 - 1 = 3)

Station 8: Physical Education

1. Flexibility
2. Cardiovascular Endurance
3. Muscular Strength

Station 9: Art

1. Complementary
2. Vanishing

Station 10: Life Skills

Classifications:

1. Mobile Phone Data Plan: Need (for communication/safety) or Want (if excessive data). Strategy: Downgrade plan or use free Wi-Fi.
2. Designer Branded Sneakers: Want (shoes are a need, but expensive designer brands are a want). Strategy: Buy standard sneakers for less.
3. Fast Food Lunch: Want. Strategy: Pack a lunch from home.
4. Required School Notebooks: Need. Strategy: Look for store brands or back-to-school sales.
5. Movie Ticket: Want. Strategy: Wait for the movie to stream at home or go on a discount day.

Budget Reflection: Total cost of needs (Notebooks $10 + Phone $25) is $35. Students should explain that they will cut down on wants (like the designer sneakers or fast food) to keep total expenses below $100.
