Light reflection, refraction, and absorption
This is what happens when light hits a mirror and bounces back.
What is reflection?
This is the type of energy an object has stored due to its position or shape
What is potential energy?
Why do many experiments include several trials (repetition) as opposed to a single trail.
What is repetition of trails reduces the impact of errors?
Which two body systems make movement possible?
What is the skeletal and muscular system?
A student is conducting an experiment to determine the effect of sunlight on plant growth. What is the independent variable in this experiment?
What is amount of sunlight received
When light travels from the air into a glass prism, what happens to its speed?
What is slowing down?/What is it slows down?
At which point of a roller coaster is potential energy the highest?
What is the top of the highest hill?
A student conducts an experiment and another student repeats the exact same steps to see if they get the same results. What is the second student doing?
What is replication?
Which process describes respiration?
What is obtaining oxygen and releasing carbon dioxide
A hypotheses states that increasing the temperature of a solution will increase the rate at which a solute dissolves. After conducting an experiment, the data does not support this hypothesis. What should be the next step?
Modify the hypothesis and conduct a new experiment
This happens when a straw looks broken or bent when you place it in a glass of water.
What is refraction?
This scientific law states that energy cannot created or destroyed only transformed
What is the Law of conservation of Energy
YScientists frequently repeat the experiments of other scientists. Why is this important in science?
What is Replication of experiments helps to confirm and verify results.
How do the circulatory and digestive system systems work together?
The digestive system absorbs nutrients and the circulatory systems transports nutrients around the body.
How can a hypothesis be valuable even if it is not supported by data?
What is it can lead to further investigations and new discoveries.
On a hot sunny day, why would a black t-shirt feel much warmer than a white t-shirt?
What is black objects absorb more light energy?
A soccer ball sitting on the ground has zero of both potential and kinetic energy. To give it potential energy, you have to do what?
What is picking it up
Experiments are often repeated many times by the same if different scientists. What is the most important reason more than one scientist should conduct an investigation using the same methods.
What is if the results are the same, it confirms the results.
Organ systems work together to meet the needs of the human body. How is the skeletal system related to the nervous system.
What is the skeleton protects the brain and spinal cord
What best describes the role of variables in scientific experiments?
What is they are factors that are changed or measured.
This tool uses refraction to help people see objects that are far away.
What is a telescope lens?
Theses are the two specific factors that determine the amount of kinetic energy an object has?
What are mass and velocity
Which statement best describes repetition and replication
What is repetition is when the same scientist repeats it and replication is when a different scientist repeats it.
Which phrase defines the term homeostasis?
What is maintenance of a stable environment inside the body.
