Chapter 18 Oceans
In this earth science learning exercise, students identify and locate various vocabulary terms pertaining to the ocean and living things found in the ocean. There are 27 ocean terms located in the word search.
Curated OER
What is life? Word Search
In this biology worksheet, learners locate and identify various vocabulary terms related to life biology. There are 48 words located in the puzzle.
Curated OER
Sea Ice
Students observe the freezing times and temperatures of water with varying levels of salinity. They determine how icebergs form, how they act, and what they may be made of. They discover that salinity level affects the time it takes...
Curated OER
Blood Tonic
Students investigate the process of osmosis using fresh potato cuttings in saline solution. In this biology activity, students explain the difference between hypertonic, hypotonic, and isotonic solutions. They collect data...
Curated OER
Hatching Brine Shrimp
Learners experiment with temperature and salinity to detect favorable environments for hatching brine shrimp eggs. They make some predictions about which environments will yield the most hatched brine shrimp and record the number of...
Curated OER
Hudson River Salt Front Activity
In this Hudson River instructional activity, students read a passage about the Hudson and salinity, they complete graph interpretation and questions and activities.
Curated OER
Technology of the Deep: Experiments with Buoyant Forces
Students conduct a series of experiments to study the effects of temperature and salinity on the buoyancy of an object in water. They devise ways to make floating and sinking objects neutrally buoyant.
Curated OER
Where's the Oxygen?
Students study seawater and how temperature and salinity influence it. In this oxygen lesson students complete a lab activity on dissolved oxygen.
Maryland Department of Natural Resources
Eyes on Dissolved Oxygen
Learn about the factors that affect the way oxygen dissolves in salt water with a chemistry lab. After studying the molecular structure of water, young scientists figure out how aeration, temperature, and organic waste affect...
NOAA
Through Robot Eyes
How do robots assist ocean explorers in collecting data and images? The final installment in a five-part series has science scholars examine underwater images collected by robots and identify the organisms shown. Groups then calculate...
Curated OER
Hot, Cold, Fresh and Salty
Students observe the effects of layering water and what is more or less saline than normal. In this geoscience lesson students create saline solutions, layer them and observe how the water becomes different temperatures in different layers.
Curated OER
Statistical Analysis for Graphing Calculators
Learners use data from the Chesapeake Bay to analyze temperature, phosphate, nitrates, salinity, and oxygen levels.
Curated OER
Investigating Convection Currents
Students examine how differences in the temperature and salinity of the water help create ocean currents. They perform an experiment which shows how temperature affects the circulation of ocean water.
Curated OER
Biocomplexity Lab Activity: Density and Buoyancy of
Students investigate how the density of water changes the buoyancy of
water. Students create a hypothesis about what will happen when placing the
egg into the water.Students can research online different bodies of water (The Red Sea, The...
Curated OER
Water Density and Stability Lab
Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.
Curated OER
Learning Lesson: Salt 'n Lighter
Students participate in a demonstration showing that as salinity increases density increases as well. They also examine the different densities of air. They discuss the amount of water displaced by large ships.
Curated OER
Hatching Brine Shrimp
Third graders investigate the environment that is considered favorable for brine shrimp hatching. The salinity level is of particular interest in the observations because the optimum level is needed for survival. They make daily...
Curated OER
Locating the Salt Front
Students use Hudson River salinity data to create a line
graph that shows the location of the salt front, and use math
skills to explore how this location varies over time. They use the graph to estimate the location of the salt front...
