A student put various items in a beaker to see what would happen. After observing the items for a few minutes, what is a reasonable conclusion that could be made by the student?
The items could be separated in one step using the property of magnetism.
The items could be separated in one step using the property of solubility.
The items could be separated in one step using the property of density.
The items could be separated in one step using the property of physical state.
A student set up the following circuit. The bulbs do not light. What change should be made for both bulbs to light?
Move one end of the wire to the negative end of the battery
Add a switch between the bulbs
Move both ends of the wires to the negative end of the battery.
Change the battery; it must be dead.
Which mixture could be separated using a strainer?
sand and salt

Jorge's mom is cooking spaghetti in a pot of boiling water. Jorge notices that when she removes the metal pot from the stove, she uses silicone gloves. Why are the gloves necessary to remove the pot of boiling water?
The silicone gloves conduct thermal energy
The metal pot conducts thermal energy
The metal pot creates thermal energy.
The silicone gloves melt with thermal energy.
A teacher at recess duty has a box of paperclips with her. She accidentally drops the paperclips in a pile of dirt. Then 12 kids run through the dirt and mix the paperclips in. What would be the most reasonable way to get all the paperclips out of the dirt?
Use a magnet to pull the paperclips out of the dirt.
Dump water in the dirt and stir until the paperclips float to the top of the mud puddle.
Wait for the paperclips to evaporate from the dirt.
Have the students who ran through the dirt use tweezers to remove the dirt from the paperclips.
In a science class, students made and recorded objects into the following data chart. Which T-chart below correctly classifies items by their physical properties?
A student mixes some milk, ice, and protein powder in a blender and turns the blender on for 30 seconds. He then opens the lid and can see the milk and some pieces of ice but can no longer see the protein powder. What is the most reasonable explanation for this?
The protein powder evaporated in the milk.
The ice pieces are too big and block the view of the protein powder.
The protein powder has dissolved in the milk and can no longer be seen.
The heat from the ice, melted the protein powder and it is invisible now.
Students placed four round objects in an aquarium full of water. Some of the objects floated and others sank, as shown in the illustration above. Which of the following is a correct interpretation of the data?
Objects X & Z have a greater mass than water.
Objects X & Z have a lower mass than water.
Objects W & Y have a greater density than water.
Objects W & Y have a lower density than water.
Students observed 4 classroom objects and recorded their physical properties in a data chart. Which data chart below correctly classifies all of the objects by their physical properties?
Which tool primarily relies on refraction to serve its purpose?
