Water Cycle
What process changes liquid water into water vapor?
What is evaporation.
What should you wear to protect your eyes during certain experiments?
What are goggles.
What two main living things are grown together in aquaponics?
What are fish and plants.
What element moves through the nitrogen cycle?
What is nitrogen.
What plant part absorbs water and minerals?
What are the roots.
What process occurs when water vapor cools and becomes liquid droplets?
What is condensation.
What should you do before beginning a laboratory investigation?
What is read/listen to all directions and understand the procedure before starting.
What do fish release into the water that eventually supplies nutrients to plants?
What is nitrogen-containing waste.
What organisms help change nitrogen into forms plants can use?
What is bacteria.
What green pigment helps plants capture light energy?
What is chlorophyll.
What is water called when it falls from clouds as rain, snow, sleet, or hail?
What is precipitation.
What should you do immediately if a spill or accident occurs?
What is tell the teacher immediately!
What helpful organisms convert fish waste into nutrients plants can use?
What are nitrifying bacteria.
What process converts atmospheric nitrogen into usable nitrogen compounds?
What is nitrogen fixation.
What gas do plants take in for photosynthesis?
What is carbon dioxide.
What stage occurs when water gathers in lakes, rivers, oceans, soil, or tanks?
What is collection.
Why should you never taste materials used during a science investigation?
What is materials may be unsafe, contaminated, or not intended for consumption.
What nitrogen compound is especially important for plant nutrition after nitrification?
What is nitrate.
What nitrogen compound is produced from ammonia during the first step of nitrification?
What is nitrite.
What sugar do plants manufacture during photosynthesis?
What is glucose.
What process describes water vapor leaving the leaves of plants?
What is transpiration.
Why is it important to follow the written procedure instead of changing an experiment without permission?
What is following the procedure protects students, controls variables, and helps produce reliable results.
Why can plants grow in an aquaponics system without soil?
What is plants receive water and dissolved mineral nutrients directly through their roots, so soil is not required.
Explain how fish waste can eventually provide nitrogen that plants can use.
What is fish produce nitrogen-containing waste; bacteria help convert ammonia into nitrite and then nitrate, which plants can absorb as a nutrient.
What vascular tissue carries water and minerals from roots upward?
What is the xylem.
