Other Classroom Activites & Projects — Jeopardy Game


  • 5×5 or 6×6 grid board.
  • Printed questions and answers on opposite sides of paper
  • 2 bells/ringer for answering

Group students into two or three teams (or have students participate individually). Choose a host and card flipper. Score five points for each correct answer and subtract 5 points for each incorrect answer. Optional scoring: sort questions by difficulty and increase points from the easiest (top) to the hardest (bottom). The host poses the answer and the teams compete to ask the question first.




This nutrient is used by diatoms to form a shell. What is silica?
This essential element is needed for respiration. What is oxygen?
These two nutrients are found in fertilizers. What are nitrogen and phosphorus?
Water Characteristics
Mass and volume are important to this property of water. What is density?
The Mississippi River delivers this type of water into the Gulf of Mexico. What is fresh water?
Cold, saltwater is more _____ than warm freshwater. What is dense?
Water is composed of these two elements. What are oxygen and hydrogen?
This phenomenon occurs when water masses separate into layers. What is stratification?
When too many nutrients are present. What is nutrient over enrichment?
What Is Or Isn’t In The Water?
The concentration of dissolved salt in water is called this. What is salinity?
The absence of dissolved oxygen in water causes this condition. What is anoxic?
DO stands for _____ _____ . What is dissolved oxygen?
These three nutrients are necessary for growth of diatoms and other phytoplankton. What are nitrogen, phosphorus and silica?
The concentration of oxygen in water is referred to as this. What is dissolved oxygen?
An area is considered hypoxic when dissolved oxygen is below this value. hat is 2 mg/L?
What Does Water Do?
This term refers to the movement of water or materials from one place to another. What is flux?
Rainwater that flows over land anddrains into streams is called this. What is runoff?
This type of pollution comes from asingle source, for instance a specificpipe at a factory. What is point pollution?
This type of pollution comes primarily from agricultural and urban runoff and other sources. What is nonpoint pollution?
The land area that is drained by a stream or river is called this. What is a watershed?
This material is carried and deposited by water. What is sediment?
This process occurs when organic matter is broken down. What is decomposition?
These organisms use up oxygen while decomposing dead plants and animals. What are bacteria?
This natural physical force causes mixing in the ocean to occur. What is the wind?
This area in the water column is where the strongest change in density occurs with depth. What is pycnocline?
This area in the Gulf of Mexico is a place where most living things cannot survive. What is the dead zone?
Oxygen is consumed during this process. What is respiration?
This process is caused by an increase in organic production where nutrient supply is high. What is eutrophication?
Living Things
This explosive increase of phytoplankton populations contributes to hypoxic conditions. What is an algal bloom?
This group of organisms lives on the ocean bottom. What is benthos?
These animals escape hypoxicconditions by leaving the area. What are crabs, shrimp and fish?
These animals cannot escape hypoxic conditions because they cannot move. What are worms and clams?
This group of algae protects itself with a thin silicon shell. What are diatoms?
These free floating plants are thefoundation of the food chain in the ocean. What are phytoplankton?
Working In The Field And With Data
This diagram shows vertical features along a transect. What is a cross section?
Samples are taken at these places. What are stations?
This pre-established line is used forsystematically setting up sample stations. What is a transect?
This plotted line shows data vertically. What is a profile?
This instrument is used to determine water clarity. What is a secchi disk?
Dissolved oxygen is measuredin these units. What are milligrams per liter?
his vertical profile of water from the surface to bottom is sampled to determine physical, chemical and biological characteristics of the ocean. What is the water column?
Location, Location
In the ocean, photosynthesis occurs mainly here. What is the surface?
Plankton land here when they die. What is the bottom?
This occurs when warmer, fresher water settles over cooler, saltier water. What is stratification?
This shallow part of the sea is an extension of the mainland. What is the continental shelf?
