&magicnumber=24&category1=Float or Sink?&category2=Properties of a Good Boat &category3=Cartesian Divers&category4=Dancing Raisins&category5=Water and the Water Cycle&question1=What is another word for float?&question2=Objects are more buoyant on what kind of water?&question3=If an object weighs less than the water it pushes away what will the object do?&question4=What is the definition for displaces?&question5=In class we saw a density demonstration using water, maple syrup and corn oil. Put the liquids in order from lightest to heaviest. Explain your answer.&question6=In our experiment what did we change to make our clay float?&question7=What are 2 properties that affect how well an object floats?&question8=Many hollow objects like an empty box, soda can or bottle float. What does hollow mean?&question9=A boat is a heavy object, but it floats in water. Explain why. Give at least 2 reasons why a boat floats.&question10=Why did the foil boat hold more weights than the clay boat? Explain.&question11=In class we saw a cartesian diver in action. Define the word diver.&question12=What happened to the diver when we compressed the sides of the bottle?&question13=What happened to the diver when we released the sides of the bottle?&question14=&question15=Explain how the cartesian diver works.&question16=In class we learned how to make raisins dance. When we mixed the water, vinegar and baking soda creating a chemical reaction, what appeared on the raisins?&question17=What happened to the bubbles when the raisins reached the surface?&question18=Why did the raisins float to the surface?&question19=Why did the raisins sink?&question20=What would happen to the raisins when the bubbles are gone?&question21=The movement of water from earth through evaporation, condensation, precipitation, and back to earth again is called what?&question22=Energy from what powers the water cycle?&question23=When water vapor cools to form clouds, it is an example of what?&question24=What occurs when clouds meet cool air and moisture falls to the ground?&question25=Sun energy changes water to water vapor when what occurs?&answer1=buoyancy&answer2=salt water&answer3=The object will float.&answer4=pushes out of the way&answer5=In order: Corn oil, water, maple syrup. Corn oil is the lightest (or least dense) because it floated. Maple syrup is the heaviest (or most dense) because it sank. Water is in between.&answer6=the shape of the clay&answer7=shape and weight&answer8=full of empty space or air&answer9= A boat floats because of: 1) its shape, 2) the air inside, and 3.) its weight and 4.) it weighs less than the water it displaces. &answer10=The foil boat was able to hold more weights than the clay boat because: 1.) the foil was stronger, 2.) the foil was lighter and 3.) the foil was easier to mold into a good shape.&answer11=something that plunges or moves quickly in one direction&answer12=The diver filled with water and sank to the bottom.&answer13=The diver filled back up with air and floated to the top.&answer14=&answer15=When you squeeze the bottle, all of the air leaves. The diver fills with water, becomes heavy and sink. When you release the bottle, the air goes back inside. The diver fills with air, becomes lighter and floats back to the surface.&answer16=bubbles or carbon dioxide gas bubbles&answer17=The bubbles popped. The raisins sank down to the bottom.&answer18=The raisins float to the surface because the bubbles attach to the grooves in the raisins helping them rise to the surface. The bubbles made the raisins buoyant. &answer19=The raisins sank back down because the bubbles popped. The raisins lost their buoyancy. &answer20=The raisins would sit in the bottom of the glass. They would not dance or move. The raisins need bubbles (carbon dioxide) in the water to dance.&answer21=the water cycle&answer22=the sun&answer23=condensation&answer24=precipitation&answer25=evaporation&value1=10&value2=20&value3=30&value4=40&value5=50&value6=10&value7=20&value8=30&value9=40&value10=50&value11=10&value12=20&value13=30&value14=40&value15=50&value16=10&value17=20&value18=30&value19=40&value20=50&value21=10&value22=20&value23=30&value24=40&value25=50&finalquestion=Label the water cycle diagram. &finalanswer=&gamename=Buoyancy and the Water Cycle&loadresult=Load Success!
