Station 1 – The Bottle and the Balloon Inquiry 1.1: The Bottle and the Balloon System: a combination of items that work together as a whole (the bottle and the balloon) ___heat from the hot pot was transferred into the system – true (from the hot water to the air in the bottle) ___steam entered the system - false ___water entered the system – false (the system was closed – nothing could get in) ___heated air rises because it is less dense than surrounding air - true ___the air rose when heated – false ( in this case the hot air expanded filling the balloon) ___heat from the hot pot made the air particles move faster and expand into the balloon –true (the balloon was elastic, this was the easiest place for expansion) ___vapor from the hot pot condensed as a liquid on the outside of the bottle - true ___heat was pulled out of the system when placed in the cold bath - true ___the gas particles in the bottle cohere to each other – false

Station #2 – Burning Candle Inquiry 1.2: Burning Candle ___the wick melted – false (the wax melted) ___the wax burned – true (carbon soot, water vapor and CO 2 gas were the result) ___a chemical reaction (chemical change) occurred when the candle was lit - true ___oxygen was required for the reaction to occur - true ___there was air in the beaker when it was placed over the flame - true ___oxygen is an ingredient in air - true ___carbon dioxide gas was released as the wax burned – true ___the carbon dioxide gas that was produced filled the beaker and pushed the air out – false (the O 2 in the air was used during combustion) ___the smoke condensed on the inside of the beaker - false ___smoke is gas – false (smoke is very small particles suspended in the air) ___water vapor was formed from the reaction - true ___the water vapor condensed as a liquid on the nearest cool surface (the beaker) - true

Station #3- Similar Objects Inquiry 1.3: Similar Objects ___the block and the sphere had the same volume - true ___the objects had the same mass – false (you never measured the mass – so you don’t know if they are the same) ___water adhered to the inside of the cylinder – true (this formed the meniscus in the graduated cylinder)

Station #4 – Describing Matter Inquiry 1.4: Describing Matter ___the rock had a greater volume - false ___the white material was less dense than the rock - true ___the minerals in the rock were cohesive (false – they were adhesive, the minerals had different colors and were different minerals so it as different types of matter attracted to one another)

Station #5 – Adding Water Inquiry 1.5: Adding Water ___the white substance was sand - true ___the black substance mixed with the water - true ___the white substance mixed with the water - true ___the black substance melted into the water - false ___the black substance dissolved into the water - true ___dissolving is a chemical change - false

Station #6 – Floating & Sinking ___ the crushed pan was more dense than the open pan - true ___both pans had the same mass - true ___the two liquids in the bottle had the same densities - false

Station #7 – Mystery Tablet Inquiry 1.7: Reacting a Mystery Tablet ___the tablet dissolved in the water - false ___dissolving is a chemical change - false ___the tablet turned to liquid - false ___gas was produced from the reaction - true ___the temperature change was a sign of a chemical change – true – energy was needed for the change, the energy came from the heat in the water. Chemical Property – Reactivity (with water) Alka Seltzer + Water CO 2 + aspirin

Station #8 – Drops on a Penny Inquiry 1.8: Drops on a Penny ___the water adhered to other water drops – false (they cohered) ___the water cohered to the penny – false (it adhered) ___cohesion causes surface tension - true
