Table 1.

The nine physical settings, the experimental variation under scrutiny, and one example item.

Setting		Variation	Example item
Buoyancy, static
	(A)	Freshwater floating on saltwater	Agency: floater vs. carrier	The fact that freshwater floats on saltwater is basically due to … □ the freshwater/□ the saltwater?	[agency: floater]
	(B)	Wood floating on water	Agency: floater vs. carrier	The fact that wood is supported by water is basically due to … the water |———————| the wood?	[agency: carrier]
	(C)	Cornflakes floating on milk	Figure: cornflakes vs. milk vs. none	Cornflakes are placed in a bowl containing milk. The fact that the cornflakes float on the milk is basically due to … □ the cornflakes/□ the milk?
					[figure: cornflakes]
Buoyancy, dynamic
	(D)	–Gas rising in a substance –CO2rising in water	Content: abstract vs. concrete	The fact that a gas rises in a substance is basically due to … □ the substance/□ the gas?	[content: abstract]
	(E)	–Gas staying down in a substance –CO2staying down in air	Content: abstract vs. concrete	The fact that CO2 stays down in air is basically due to … □ the CO2/□ the air?	[content: concrete]
	(F)	–Gas staying down in a substance –CO2staying down in air	Figure: gases vs. substances Content: abstract. vs. concrete	CO2 rises in water. The fact that CO2 stays down in air is basically due to … □ the CO2/□ the air?	[figure: substances]
Mutual attraction
	(G)	Vinegar and oil, not mixing	Agency: vinegar vs. oil vs. both	The fact that vinegar does not mix with oil is basically due to … □ the oil/□ the vinegar?	[agency: vinegar]
	(H)	Water and fat, repelling	Agency: water vs. fat vs. both	The fact that water and fat repel each other is basically due to … □ the water/□ the fat?	[agency: both]
	(I)	–Celestial bodies attracting each other –Earth and moon attracting each other	Content: vs. concrete	The fact that earth and moon attract each other is basically due to … □ the moon/□ the earth?	[content: concrete]
