Shelby filled three empty soda bottles with 5 g of steel wool, a material used for cleaning that also rusts quickly. She added 100 mL of water to each bottle and then resealed the bottle. She placed each bottle in one of three different locations: in a refrigerator at 3 °C, in a room at 25 °C, and in a warm kitchen at 30 °C. She observed the bottles every day for a week and recorded the amount of rust that formed on the steel wool. Which research question does this experiment best investigate?

• Does a gas form when steel wool rusts?

• Does the temperature in a room vary widely over time?

• Does the amount of water effect how quickly steel wool rusts?

• Does temperature affect the amount of rust that forms on steel wool?

The nucleus of an atom is its tiny central region, and comprises the bulk of the atom's mass, containing the protons and neutrons.

• True

• False
