5G Science 1st 9wks Review

A student wants to find out which material transfers thermal energy the BEST. Which option describes the best way to conduct this experiment?

• Place the three rods in a freezer to find out which becomes the coldest.

• Place one end of each rod in very hot water to find out which becomes hot the fastest.

• Put each rod in ice water to find out which loses the most heat.

• Place the rods on a table in a classroom and find out which feels warmest by guessing.

Samuel is conducting an experiment to test the relative density of objects by placing them in a water tank. Which of these objects do you predict are less dense than water? What will happen when the objects are placed in the water tank?

• All three objects will remain suspended in the water.

• When the objects are placed in the water tank, the plastic ball and the styrofoam ball are less dense than water and will float.

• The steel object will dissolve in the water.

• All three objects will sink to the bottom of the water tank.
