First graders investigate the various forms of water. They discuss the properties of water. They discover examples of water's various states and locate other solids, liquids, and gases in their homes.

Students define lake life zones. They define stormwater runoff and its effects on lakes. They identify the relationship between decaying substances and water pollution. They construct a freshwater food web.

Young scholars investigate gases and liquids. In this states of matter online lesson, students examine how evaporation plays a part in the transition of liquids into gases as they watch a kettle of water boil and then work in small...

Hate to vacuum, but enjoy using a vacuum pump? Explore a instructional activity that starts with a demonstration of boiling water at various temperatures by using a vacuum pump. Then scholars design their own experiments to measure vapor...

Students measure salt content in water. They determine salt content of four samples using a hydrometer.

Fifth graders make rain forest terrariums in order to observe a simulated mini-environment. They place the layers and plants into container and place where it can be observed. They observe the closed water system in the container before...

The lesson seeks to intorduce to learners the properties of salt water and how to create salt water. Teacher gives backgound information about salt water to students. From that point, learners dscuss what elements are in salt water....

Learners investigate some of the factors that determine the amount of runoff. They are reminded that infiltration and runoff tend to work oppositely. When conditions are bad for infiltration they usually lead to runoff.

In this ocean salt worksheet, students read about the processes that have lead to the salt content in the ocean. Then students complete 5 short answer questions.

In this weather worksheet, students read about the mechanics of a hurricane and then complete 4 short answer questions based on the reading.

For this outcome science 4 worksheet, students apply scientific knowledge to answer and calculate a variety of questions. Students research the answer to several questions using the websites suggested.

In this oil spill quiz learning exercise, students respond to 10 multiple choice questions in order to examine their knowledge of oil spills and their effects.

Students conduct a hands-on activity to investigate salt concentrations in water and how salt remain after water evaporates. They can also do a Saltwater Painting to once again observe the evaporation. process.

Students examine the process of evaporation. They observe how when clay dries, the water evaporates and how the weight of the object decreases. They complete a worksheet to complete the lesson.

In this vapor pressure learning exercise, students use a given graph of the vapor pressure of four liquids to answer eleven questions. They compare and find boiling points and vapor pressures of propanone, ethanol, water, and ethanoic acid.

In this chemical and physical change worksheet, learners are given details about chemical and physical changes. They are given 2 examples using water and salt and they identify 15 statements as chemical or physical changes. Students...

In this models worksheet, students read about how models are used to communicate events or principles in science. They are given an example and answer 4 questions about models. They discuss accuracy and inaccuracy of models. They create...

Students collect weed seeds from three varieties of weeds (knapweed, thistle, or toadflax, for example they may choose others in addition to the spotted knapweed.) They sterilize soil for thirty containers, plant seeds in sterile soil,...

Equip young campers with important survival knowledge with a set of engaging lessons. Teammates work together to complete three outdoor activities, which include building a shelter, starting a campfire, and finding directions in the...

First graders investigate the changing states of water.

Fourth graders observe and demonstrate the physical change of dissolving sugar in water and evaporating the water to examine the physical change that has occurred. They discuss physical changes and solutions, and make rock candy,...

In this composition of soil learning exercise, high schoolers study the make-up of soil by identifying the amount of air in the soil, the amount of water in the soil, the size of the mineral grains in the soil and the proportion of humus...

Students discover how rocks are created.  In this rock formation lesson, students investigate saturation, evaporation, and phase changes in geology.  Students create rock candy from skewers, string, boiling water and sugar.

Students grow salt crystals by making a saturated solution of table salt and let the solution sit around and evaporate.
