How fast does water cool? First fifth graders will draw a line on a graph that predicts how fast they think water can cool from boiling. Then they plot the actual data on the same graph to see if their estimate was correct.

Students predict, experiment, and draw conclusions about the safety of drinking water. In this ecology lesson, students participate in an experiment to determine if they can taste or see contamination in drinking water. Data is collected...

Learners study the water cycle and how the sun is an important factor.  In this water cycle lesson students investigate how to desalinate water and explore the different densities of fresh versus saltwater.

Students construct their own water filter to obtain clean water. In this filtration lesson, students produce tainted water in order to properly filter it with filtration devices made in class.

In this shipping on the Hudson River worksheet, students record information about types of vessels seen on the Hudson River and respond to the questions that follow about each. Then they identify the Alice Oldendorff which carries road...

Rivers aren't just a place for animals to live, they also provide industrial transportation. The class will examine the Hudson River on a map, discuss all the commercial vessels that use the River to transport materials, then complete a...

Your young apprentices build a function describing the percent concentration of salt in a brine. The rational function is then related to the parent function, y= 1/x, and graphed. Finally, the apprentices predict the amount of fresh...

Why does Nia's water taste saltier than Trey's if she put more into her cup than he did? Math masters set up proportions in order to compare the mixtures. This task effectively has learners apply the concepts of ratio and proportion to a...

Although this is a science lesson, it can be adapted to help meet Common Core standards in math as well. Starting scientists describe physical properties of objects and explore three forms of water. To address the Common Core, they can...

Students map and calculate the area of the school parking lot and then the volume of water falling on the school parking lot. They map the route surface runoff will take to the nearest water body and describe the roles that human...

Students create observable layers in water that represent a separation based upon density differences. They model density boundaries using differences in temperature and salinity. They, in groups, perform a meaningful experiment...

What does math have to do with a sore throat? When you mix water and salt you have a great review of how to represent proportional relationships by an equation or graph. Here the proportions of the mixtures may be different, but the...

It's all about density! Here's a dense workbook for young scientists; they solve (and show work for) 29 density word problems, including a problem where they solve for the density of Godzilla. They complete labs analyzing metal...

The language and features of functions get careful treatment in a complex but doable lesson. Learners get a lot of practice really figuring out what a graph means in context, and also identifying key features of graphs. Key ideas...

Students study Archimedes' Principle, flotation and the reaction of buoyant forces and explain the relationship between density and flotation.

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

Students aim to explain the need for standardization of units of measurement. They pose their own standards for the value of a kilogram and compare them with the currently used standard.

Students solve word problems and determine quotients of fractions and mixed numbers. They practice multiplying fractions by increasing a recipe found on a food website. In addition, they increase the numbers to feed the whole class a...

Fifth graders take a close look at the types of ships that travel through the Hudson River Valley on the Hudson River. They utilize worksheets embedded in the plan in order to answer questions about exactly what is being shipped, and how...

Students predict and explore to discover which objects sink or float in fresh and salt water, predict how salt affect objects, write predictions on T chart, discuss difference between man-made and natural waters, and graph results.

In this algebra worksheet, students rewrite word problems using algebraic symbols. They solve for the amount of population or money over a period of time. There are 10 questions with an answer key.

Budding math buddies work together to multiply fractions by whole numbers. All of the problems involve real-life applications, making this an extension of simply practicing the skills. Knowledge will be multiplied by completing this...

Middle schoolers describe limitations of fresh water resources on ships at sea. They realize the value of fresh water on the ocean and around the world. Students gain a knowledge of the process and economic cost of desalinization.

Students identify diffusion and its processes through experimentation and calculations. They also use a CBL and conductivity probe to measure the conductivity of various solutions and study the effect of concentration gradients on the...
