Why is Venus so much hotter even though it is further away from the Sun? SC.8.E.5.7
Venus doesn’t have an atmosphere which causes the planet to become much hotter than other planets.
Venus’ atmosphere is so dense that heat is trapped and can barely escape, making it hotter than other planets.
Venus has different layers in our atmosphere which causes Venus to be hotter.
Venus atmosphere is so thin that heat is able to pass through and make the planet hotter.
Which of the earlier models of the Solar System, Geocentric or Heliocentric, is most similar to the Solar System as we know it to be today and why? SC.8.E.5.7
A. Geocentric, because only the moon is shown orbiting the Earth.
B. Geocentric, which includes all eight planets.
C. Heliocentric, which includes all nine planets.
D. Heliocentric, because the planets are orbiting the Sun.
What will weigh more when a chemical change is complete? The reactants before the chemical reaction, or the product after the reaction is complete? SC.8.L.18.4
Green plants produce their own food during photosynthesis. This image shows the process of photosynthesis. What are the products of photosynthesis? SC.8.L.18.4
carbon dioxide and water
the sugar glucose and oxygen
chlorophyll and mitochondria
chlorophyll and chloroplast
The process of cellular respiration makes it possible for Kristine to run on the treadmill and to lift weights. What do her cells do during cellular respiration? SC.8.L.18.4
convert kinetic energy into chemical energy
absorb light energy through the chlorophyll in their chloroplasts
break down food molecules to form energy
combine water and carbon dioxide to produce oxygen and glucose
Pablo notices that ice cream melts when left out at room temperature. What is Pablo observing? SC.8.P.9.2
A physical change
A chemical change
A chemical reaction
The formation of a new substance
Which of the following describes an example of a material undergoing a chemical change to become another material with different characteristics? SC.8.P.9.2
Which of the following best describes how chemical changes differ from physical changes? SC.8.P.9.2
Physical changes produce no new substances and chemical changes do.
Physical changes always involve the formation of a gas while chemical changes may not.
Physical changes can occur inside or outside the substance; chemical changes always occur outside.
Physical changes involve a change of state; chemical changes involve a change of shape.
