Learning Lesson: Salt 'n Lighter
Pupils 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
Sink or Float Experiment
Students participate in an experiment to determine which objects float or sink. They use different amounts of salt for the objects and discover as the salt content increases, objects will float. They record their predictions and what...

Using A Winogradsky Column to Analyze Microbial Communities
Pupils use easily obtained materials to study ecological succession in a microbiological community. They collect water samples from outdoor sources in plastic bottles to observe and record changes.
Curated OER
Relating Number of Insect Species to Water Quality
Students are asked to respond to questions such as:" Have there been surveys of the area to inventory the species?" (For example, for a wetland area, do they know what amphibians live there and how abundant they are?) Are there any...
Curated OER
Tracking the Salt Front
Students manipulate Hudson River salt front data from October 2004 -
September 2005 to locate the high and low points of the salt front for each month, They determine the range for each month, determine the modal range for each month,...
Curated OER
Locating the Salt Front
Learners 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...
Curated OER
Where Do Fish Live in the Hudson?
Learners explore the environmental factors that influence where fish live and determine the makeup of fish communities in the Hudson. They interpret guided observations and measurements to assess patterns, sequences and relationships.
Curated OER
Daily Survival Requirements of Water
Students will use inquiry science to complete an investigation. They create hypotheses predicting the changes water undergoes in becoming ice and determine how much ice needs to be melted to create one 8 oz. glass of water.
Curated OER
Fish Communities in the Hudson
Students use tables of fish collection data to draw conclusions about where fish live in the Hudson Estuary. Given available data they interpret organized observations and measurements and recognize simple patterns, sequences, and...
Curated OER
Daily Edits: Water
In this sentence correction worksheet, students read the sentences and rewrite them by editing them with corrections. Students complete 4 examples.
Curated OER
Surface Tension On Coins
Students drop water onto clean coins to determine the tension of each coin and then to graph their findings.
Curated OER
Animal Life Histories Derived From Morphology
Students learn the mechanisms of natural selection by deducing information from the physical appearance of the animal.
Curated OER
Boy, Is That Buoyant!
Fourth graders see that salt increases the density of water and creates a condition wherein objects are more buoyant than would be expected under normal conditions. They describe the relationship between heat energy, evaporation and...
Curated OER
Investigation 4 - Dinosaurs Tracks
Fourth graders make inferences and interpretations from sets of dinosaur tracks. They describe Utah fossils and how they were formed. Partners trade their sketches of tracks and try to guess which dinosaur it belonged to.
Curated OER
"Pennsylvania Watersheds, Many Ways to the Sea"
Students trace a molecule of water through the water cycle including each of its three loops. They describe why evapotranspiration demands the largest portion of total precipitation falling on a forested watershed.
Curated OER
NOAA Research Project
Students research any topic relating to the National Oceanic and Atmospheric Administration (NOAA) research cruise that Mrs. Richards be participating in.
Curated OER
Glacier Climbing
Students discuss glaciers and the current distribution of glaciers around the Earth. They create simulated glaciers using cornstarch, shoeboxes, water, and pebbles.
Curated OER
Ecology
Fourth graders research an ecosystem and its endangered species. They create a PowerPoint Presentation, oral report, poster or a booklet based on their research. They research on the internet and in biology texts in teams of 4.
Curated OER
DOES A FLUCTUATION IN TEMPERATURE IFFECT THE GROWTH AND SURVIVAL RATE OF AQUATIC PLANTS?
Students determine if different temperatures effect the growth and survival rates of aquatic plants and evaluate the optimal temperature for the growth of aquatic plants.
Curated OER
Lotic Environment
Students assemble a classroom river model as an example of a lotic system. They control and measure biotic and abiotic information for the in-class system and compare data with a lotic system in a natural environment.
Curated OER
Investigation of the Aral and Salton Seas
Students become more environmentally conscious. They see that it may be too late to "save" the Aral Sea, but there is still hope to prevent the ecological collapse of the Salton Sea.
Curated OER
Water, Water Everywhere, and Nary a Drop to Drink!
Students sing the continent song and locate oceans between the continents on a map. They read "They Earth is Mostly Ocean" and copy notes into their journals. They watch a demonstration of water and saltwater evaporated to see what is...
Curated OER
Florida's Springs
Students follow the journey that water takes in aquifers and springs. They write about the major threats to the aquifer and the solutions to these threats.
Curated OER
Florida Springs
Students discover the many uses of water and the sources of the water we see. They complete a worksheet about the water usage at school and at home.
