The radiometer moves when: the white t-shirt because it absorbs more thermal energy. the white t-shirt because it reflects light energy the black t-shirt because it absorbs light energy both shirts, more layers help stop thermal energy On a hot summer day, in order to stay cool you would wear: Before 40 mL After 80 mL What is the volume of the rock? 10 mL 80 mL 30 mL 40 mL Sound is produced by - energy changing form changes in the state of matter thinking about objects vibrating objects the blue layer is less dense than the green layer, and more dense than the red layer the red layer is less dense than the white layer, and more dense than the green layer the golden layer is the most dense the brown layer was poured into the graduated cylinder first Which of the following is true? Theresa was performing an investigation using the items pictured above. She stretched the rubber band and plucked it. She then held the ruler in one hand while pulling it back in the other and letting go. She then hit the top of the drum with the drumstick. Theresa's investigation is most likely about - vibrations producing sound how objects produce light lab safety how to record music light, chemical, and sound light, thermal, and solar mechanical, light, and solar light, thermal, and sound Which of the following types of energy come from the sun? Look at the devices below.
All of these devices produce - energy sound magnetic force light copper wire plastic copper is an insulator plastic is an insulator plastic is a conductor none of these The picture shows the inside of an electrical cord. Which of the following statements are true? The picture represents a model of a ______________. thermal energy circuit electrical outlet flash light Which item is designed to change electrical energy into thermal energy? desk lamp campfire electric guitar oven Which item is designed to change electrical energy into sound energy? desk lamp campfire electric guitar oven Sugar dissolves quickly in coffee because the coffee
is ______________. black cold liquid hot What is the freezing point for water in degrees Celsius? 32 100 0 212 Margo was making tea for a party. She made 4 pitchers of tea and measured the temperature in each one using a thermometer. In which pitcher of tea will sugar dissolve the slowest? A 50 C A B 90 C B C 70 C C D 20 C D light is refracted at an angle the water is a liquid light cannot pass through the glass light is being reflected Look at the picture below. Which explains why the straw looks broken under the water? friction The diagram shows a ramp with a rock at the bottom. A rope is attached to the rock and the rope goes over a pulley at the top of the ramp. A weight is attached to the other end of the rope. What would be most responsible for the rock being pulled up the ramp? gravity air density kg The picture shows the effect of a river on an area over many years. Which process caused the valley to form? valley deposition evaporation condensation erosion river river delta How was the delta most likely formed in the picture? glacier movement deposition of sediment precipitation evaporation when the sun heats water and it turns into water vapor. when sediment is dropped off. the movement of sediment. the break down of rock into sediment. Erosion is ... when the sun heats water and it turns into water vapor. when sediment is dropped off. the movement of sediment. the break down of rock into sediment. Deposition is ... when the sun heats water and it turns into water vapor. when sediment is dropped off. the air temperature around us. the break down of rock into sediment. Weathering is ... Why does the clay boat float but the clay ball sinks? because the clay boat has more density. because the clay ball has more density. because the clay boat is lighter. because the clay ball has less density. Damon road his bike off the concrete road into the grass. He observed that his bike became harder to peddle when he rode in the grass. This happened because he got a flat tire the grass is not smooth and caused friction he wasn't wearing safety goggles his brakes weren't working Which physical property of an apple would change if you took a bite out of it? none of these the mass the taste the smell What is the first step in the scientific method? making a graph stating the problem or question recording the data forming a hypothesis magnetism gravity the amount of force from his arm Bill made a paper airplane and threw it across the room. Which of the following forces would not affect the distance the plane flies. something that we change on purpose. an educated guess. the results of the experiment. something we keep the same the entire experiment. A manipulated variable is When we eat a carrot, what part of the plant are we eating? root stem leaf fruit Which of these is not a function of roots? support the plant soak up water for the plant makes food for the plant gets nutrients from the soil Jenny took a picture of the moon. Her teacher said the picture shows the moon in the waxing crescent stage. About how many days will it take to reach the waxing crescent stage again? 10 days 30 days 90 days 5 days Bounty Which paper towel brand was most absorbant? Sparkle Western Family Scott Bounty Which paper towel brand was least absorbant?
