Marina is trying to make a model that shows Terrance that even though the water was no longer in the pot, it was not destroyed. She wants to show the principle of Conservation of Mass. Which model should she use to help Terrance understand that matter isn't destroyed when it changes? Options: Water evaporating from a puddle, Burning a log into ash, Mixing oil and water, Weighing a piece of paper, ripping the piece of paper into many pieces and weighing it again

Back

Weighing a piece of paper, ripping the piece of paper into many pieces and weighing it again

Answer explanation

The correct choice is weighing a piece of paper, ripping it into many pieces, and weighing it again to demonstrate Conservation of Mass.

Said poured 5 cups of water into a bowl two weeks ago and placed it in the freezer. He took the bowl out of the freezer yesterday and accidentally left it on the counter while he was at school. When he returned home from school, the ice had melted in the bowl. Said measured the amount of water that came from the melted ice. Which should be the amount of water that is in the bowl?

Back

5 cups

Answer explanation

The correct amount of water in the bowl should be 5 cups, as the ice melted back into the original 5 cups of water that Said poured into the bowl.

Answer explanation

The FIRST STEP in the rain formation process is when water warms and evaporates into the air.

Front

What is the SECOND STEP in the rain formation process?

Back

As the water vapor rises in the air, it cools and condenses to form clouds.

What is the THIRD STEP in the rain formation process?

Back

Clouds are redirected higher in the atmosphere by mountains produce rain.

Answer explanation

The correct choice, 'Clouds are redirected higher in the atmosphere by mountains produce rain,' is the third step in the rain formation process as it explains how rain is produced due to the rain shadow effect.

What is the FOURTH STEP in the rain formation process?

Back

Clouds fall lower in the atmosphere on the other side of the mountain and carry small liquid water droplets over land.

Answer explanation

The FOURTH STEP in the rain formation process is when clouds fall lower in the atmosphere on the other side of the mountain and carry small liquid water droplets over land.
