Year 8 Science Deep Blue Escape Room: Underwater Research Facility Theme: States of Matter and Chemistry Scenario; You and your team are trapped inside a high-tech underwater research facility. A malfunction has locked down the complex, and the main door will remain closed unless you solve a series of chemistry and states of matter-related clues. Each clue will help you unlock a code, and the final code will free you from the facility. Use your knowledge of states of matter, chemical reactions, and properties of water to find the answers, record your results before time runs out! _______________________________________________________________________________ Clue 1; States of Matter (Solids, Liquids, Gasses) Clue; The control panel displays a locked keypad with several missing numbers. To unlock it, you need to understand how water behaves at different temperatures. Specifically, you need to know the temperatures at which water transitions between different states of matter. Task; Fill in the table with the correct temperatures at which water changes its state. States of Matter Transition Temperature Solid (Ice) 0℃ (freezing point) Liquid (Water) 100℃ (boiling point) Gas (Steam) (Boiling point) Bonus; The temperature of water at boiling point (100℃) will be used for your first code. Clue 2; Water as a Solvent (Solutions and Solubility) Clue; The research facility’s chemical analysis system shows a series of liquids, and you are to identify how many grams of salt dissolve in 100ml of water at room temperature to form a saturated solution. Task; Look at the table below and identify the correct solubility for salt and sugar in water. Solute Solubility in Water (g/100mL) Salt (NaCl) Sugar (Glucose) Question; How many grams of salt dissolve in 100ml of water at room temperature (25℃) to form a saturated solution? Bonus; Record the number of grams that can dissolve in 100ml of water as your next code.  Clue 3; Chemical Reactions (Reactants and Products) Clue; A locked console asks you to predict the products of a chemical reaction when hydrochloric acid (HCl) reacts with sodium bicarbonate (NaHCO3). The reaction produces carbon dioxide gas, but how do you balance the equation? Task; Write the correct balanced chemical equation for the reaction between hydrochloric acid and sodium bicarbonate: Unbalanced Equation; NaHCO3 + HCl + H2O + CO2 Reactant 1 Reactant 2 Product 1 Product 2 Sodium Bicarbonate Hydrochloric Acid Sodium Chloride Water (H2O) (NaHCO3) (HCl) (NaCI) Carbon dioxide (CO2) Bonus: Record the number of products formed in this reaction (hint: there are 4 products), as your next code. Clue 4; Density and Buoyancy (Properties of Minerals) Clue; You’re presented with three materials inside the facility’s lab: lead, aluminum, and wood. The control system asks you to identify which material will float on water based on its density. Task; Use the table below to calculate and rank the materials based on their density. The density of water is (g/cm³). Materials with a lower density than water will float. Material Density (g/cm³) Lead 11.34 Aluminum 2.70 Wood 0.70 Question; Which material will float in water? Record the name of the material that floats as your next code. Clue 5; Acids and Bases (pH scale) Clue; The system inside the facility asks you to test the pH level of various liquids. You are to identify which substance is acidic and which is a base based on their pH levels. Substance pH level (Acid/base) Lemon juice Ammonia Solution Pure water Vinegar Task; Identify whether each substance is acidic or basic based on its pH level. Use the following: Acidic substances have a pH less than 7. Basic substances have a pH greater than 7. Neutral substances have a pH of 7. Bonus: Record the pH level of vinegar (Hint: Vinegar is commonly used as a cleaning agent and its pH is acidic). The pH value will be your next code. Clue 6; Phase Changes and Energy (Latent Heat) Clue; In the control room, you’re shown a chart of different phase changes and the amount of energy required for each change. You need to calculate how much energy is needed for 1 kg of ice at 0℃ to melt into water. Task; The latent heat of fusion for water is 334 J/g. To calculate the energy required for 1 kg (1000 grams) of ice to melt, use the formula: Energy = mass x latent heat Bonus; Calculate the energy required to melt 1 kg of ice and write down the number of joules as your final code. Final Code: Now that you’ve solved all the clues, here’s a summary of the codes you’ve obtained. Clue Code Clue 1: States of Matter Clue 2: Water as a Solvent Clue 3: Chemical Reactions Clue 4: Density and Buoyancy Clue 5: Acids and Bases Clue 6: Phase Changes & Energy Final Code to Unlock the Door: (Combine all your answers to get the final code!) Bonus Activity: To extend the challenge, create a mini-report about how phase changes affect materials in the real world, or explore how density affects buoyancy in different liquids. You can use the clues from the escape room to support your findings!
