Characteristics of Life
All living things are made of one or more of these.
What is made of cells?
The smallest unit considered alive.
What is a cell?
An educated, testable prediction for what might happen during an experiment.
What is a hypothesis?
These should be worn whenever chemicals, heat, or flying materials could damage your eyes.
What are safety goggles?
Ms Hiapos favorite phrase.
What is what the nuts?
A sunflower bends toward sunlight. This demonstrates this characteristic of life.
What is response to a stimuli?
A group of similar cells working together for a specific function.
What is a tissue?
The variable deliberately changed by the scientist.
what is the independent variable?
An idea someone accepts as true based on personal values, culture, religion, or experience rather than requiring scientific testing.
what is a belief?
Define the term: fact
What is
A statement that can be verified using evidence or observation.
Sweating when your body gets too hot is an example of maintaining stable internal conditions.
What is homeostasis?
Put these in order from smallest to largest: organism, organ, cell, tissue, organ system.
What is cell → tissue → organ → organ system → organism?
A student changes the amount of sunlight plants receive and measures their growth. This is the dependent variable.
What is the plant growth?
A student wants to smell an unknown chemical. Instead of smelling it directly, they should use this technique.
What is wafting?
Name the levels of organization of a human from smallest to largest in 10 seconds.
Cell → Tissue → Organ → Organ System → Organism
A puppy becoming a full-grown dog demonstrates these two related characteristics of life.
What is growth and development?
The stomach contains muscle tissue, nervous tissue, and epithelial tissue working together. Therefore, the stomach is at this level of organization.
What is an organ?
A scientist tests whether fertilizer affects plant growth. All plants receive the same water, soil, pot size, and temperature. These are called this type of variable.
What are a controlled variables?
Evolution and cell theory are examples of this: a broad scientific explanation supported by a large amount of evidence.
What is a theory?
The name of the scientific building that replicates Earth in Tucson.
What is the Biosphere 2?
A population of bacteria becomes resistant to an antibiotic after many generations. This demonstrates this characteristic of life.
What is adaptation/evolution?
A student is studying the digestive system, which includes the stomach, intestines, liver, and other organs working together. Identify its level of organization AND the level immediately above it.
What is an organ system and organism?
A student’s results do NOT support their hypothesis. This is the best scientific response: change the data, call the experiment a failure, or use the results to revise the hypothesis and investigate further.
What is revise the hypothesis and investigate further?
Students sometimes say, “A theory eventually becomes a law when scientists prove it.” Explain why this is incorrect.
What is theories and laws have different purposes; theories explain how/why phenomena occur, while laws describe consistent patterns or relationships?

What is Diet Coke?
