Students describe different types of water pollutants. They complete experiments in which they observe the affects of water pollution on algae. They also brainstorm and list three causes of each water pollutant.

Students determine whether various rocks are porous or not. They conduct an experiment to determine if a brick is porous, calculate how much water the brick soaked up, and develop a conclusion.

Students investigate hydrothermal vents by observing a simple model designed to show that hot water rises when it's heated. First, students listen as the teacher explains hydrothermal fluids and vents. Students watch as the teacher...

In this calculus instructional activity, students answer 5 short-answer problems regarding different salt solutions per gallon, various size tanks, water flow and time.

Students investigate nutrient cycling in a simplified desktop ecosystem involving aquarium and hydro-ponically grown plants. They set up an aquarium with 10 gallons of water at least a week before the lab is planned and place...

Half are real-world. The 2011 AP® Calculus AB free-response questions let pupils and teachers see how content appears on the exam. Half of the questions contain real-world context, and four items do not allow calculators. Real-world...

Learners are given a volume of a rectangular tank and are asked to find the water height. Because the total volume of the tank is given in liters, your geometers will need to use a unit ratio to convert to centimeters cubed. The exercise...

Students use simple materials to make model sailboats which must stay upright and sail straight in a testing tank.

Pupils examine an article about tsunami warning systems and discuss why they are important. They conduct an experiment that shows how the velocity of a wave in water changes with the depth. 

Students demonstrate how ocean currents are influenced by changes in density. They discover that temperature and salintiy affect density as well. They participate in a short experiment to end the lesson.

Students examine various scenarios about pollution around bays and discuss their reactions to them. Among the situations they investigate are construction site soil washing into a tributary, oil from motor boats leaking into water, and...

Young scholars, using wood blocks and model boats, investigate how the shape of an object affects friction it encounters as it is drawn through a towing tank.

Young scholars read a story problem about the issue of hazardous waste and pollution in a fictional town. In groups, they create a topographical map and predict how the water might flow and determine the place of contamination. To end...

Investigate velocity using Torricelli's Law! The class will have a blast solving problems involving velocity and their related equations. They create an equation to represent the flow of the water through a tank. Super helpful tips on...

Students observe tadpoles as they gradually change into adults.  For this amphibian biology lesson, students watch tadpoles in a tank in the classroom, keep a daily record of what they observe, and chart the growth development of...

For this density demonstration, students compare a can of diet coke to a can of regular coke. They list the similarities and differences of each prior to the demonstration. The cans are placed in a tank of water and students record their...

Students examine the importance of tsunami warning systems. They read and discuss an article, conduct an experiment in a wave tank, calculate wave velocities of tsunamis, and identify what happens to tsunamis as they approach a shoreline.

Students predict and test how the effects of velocity and force of an object or air on water affect the waves created. They diagram a water park ride using their knowledge of these effects to create their desired outcomes.

Young scholars comprehend the interactions of pH, alkalinity, hardness, and carbon dioxide in aquaculture water. They read the SRAC fact sheet number 464 "Interactions of pH, Carbon Dioxide, Alkalintiy and Hardness in Fish Ponds." ...

In this groundwater pollution activity, students use a piece of bread to represent the earth, food coloring to represent contaminants in the ground and water to simulate the movement of pollutants with water through the ground. Students...

Students consider the limitations of deep water oceanography and design an underwater habitat to support scientists while they complete long term studies under the ocean. In this engineering lesson, students are introduced to the...

Students, through a series of lessons, study the various processes of treating wastewater. They participate in discussion and complete various worksheets and a hands-on activity, in which they observe the processes of filtration and...

Students watch a demonstration with a balloon filled with water being buried in a milk container that has been cut length wise and filled with sand. Students are told that there is an underground storage tank filled with a contaminate...

In this density activity, students modify three film canisters in order to make one float in a tank of water, another suspend in the middle of the tank, and the third should sink to the bottom. They collect data on their canisters and...
