Scientific Inquiry
A prediction with an explanation or an educated guess.
What is the definition of hypothesis?
The first step of the scientific method.
What is an observation?
True or false? Glucose and oxygen are reactants of photosynthesis.
What is false?
True or false? Carbon dioxide is a product of cellular respiration.
What is true.
The process of making food in a plant is called___________.
What is photosynthesis?
What is the responding variable or factor that may or may not change due to manipulation?
What is Dependent Variable.
The number of parts in an experiment that you should change.
What is one? Only the independent variable should be changed by the researcher. Every other variable should remain constant.
Who goes through the process of photosynthesis?
What are autotrophs or producers
What organisms go through the process of cellular respiration?
What all living things: plants, animals, protists, fungi, bacteria etc.
The process by which glucose and oxygen break down to release stored energy is called________________.
What is cellular respiration?
The controlled variables.
What are the variables are not changed during an experiment?
4 feet long with 24 buttons are both examples of what type of observation?
Quantitative Observation
What part of the plant captures energy from the sun?
What are the chloroplasts or chlorophyll?
True or False? Oxygen, water, and sunlight are the reactants of cellular respiration.
What is false?
What chemical formula is the following?
6CO2 + 6H2O + Sunlight --> C6H12O6 + 6O2
What is photosynthesis?
If you were testing how sunlight effects the growth of rose bushes, what you should keep the same for all the bushes.
What is the water, soil, type of bush, etc.?
Blue, rough, metal are all examples of what type of observation?
Qualitative Observation
What part of the plant allows gases like carbon dioxide and oxygen to enter and exit the plant?
The stomata
What is the importance of Cellular Respiration?
The process cells use to take food energy and turn it into ATP.
What chemical formula is the following?
C6H12O6 + O2 --> CO2 + H2O + ATP
What is Cellular Respiration?
Find the independent and dependent variables in the following experiment: If you increase the number of times you practice shooting free-throws, then you will increase your chances of making a basket every time.
What is Independent- practice shooting free throws, Dependent- making baskets.
If you are testing the impact that water temperature has on the time it takes to dissolve sugar. What is your independent variable? What is the dependent variable?
Independent: Water temperature
Dependent: Time it takes to dissolve sugar
Chlorophyll is green because_______________
What is: Chlorophyll absorbs all other colors (red, orange, yellow, blue, indigo, and violet), but reflects green.
What part of the cell converts glucose and oxygen into usable energy, carbon dioxide, and water?
What are the mitochondria?
It is not a physical input to photosynthesis, but is required for the reaction to proceed. Because of this, we write this form of energy above the arrow in the chemical equation for photosynthesis.
What is sunlight? What is light energy
