scienceQA-3298	multiple_choice	What do these two changes have in common? tearing a piece of paper butter melting on a hot day	[ "Both are caused by heating.", "Both are caused by cooling.", "Both are only physical changes.", "Both are chemical changes." ]	C	Step 1: Think about each change. Tearing a piece of paper is a physical change. The paper tears into pieces. But each piece is still made of paper. Butter melting on a hot day is a change of state. So, it is a physical change. The butter changes from solid to liquid, but it is still made of the same type of matter. Step 2: Look at each answer choice. Both are only physical changes. Both changes are physical changes. No new matter is created. Both are chemical changes. Both changes are physical changes. They are not chemical changes. Both are caused by heating. Butter melting on a hot day is caused by heating. But tearing a piece of paper is not. Both are caused by cooling. Neither change is caused by cooling.

Use the arrows to follow how matter moves through this food web. For each answer choice, try to find a path of arrows to the earthworm. The only arrow pointing from the grizzly bear leads to the mushroom. No arrows point from the mushroom to any other organisms. So, in this food web, matter does not move from the grizzly bear to the earthworm. There are two arrows pointing from the barren-ground caribou to other organisms. One arrow points to the grizzly bear. The only arrow pointing from the grizzly bear leads to the mushroom. The other arrow pointing from the barren-ground caribou leads to the mushroom. No arrows point from the mushroom to any other organisms. So, in this food web, matter does not move from the barren-ground caribou to the earthworm.There is one path matter can take from the rough-legged hawk to the earthworm: rough-legged hawk->earthworm. mushroom. No arrows point from the mushroom to any other organisms. So, in this food web, matter does not move from the mushroom to the earthworm..
