Is your current lesson plan for salt and freshwater literacy leaving you high and dry? If so, dive into part one of a seven-part series that explores the physical features of Earth's salt and freshwater sources. Junior hydrologists...

An educational lesson allows young chemists to test the solubility of different types of salt at various temperatures. Groups create a graph using data from unsaturated, saturated, and supersaturated solutions.

Observe the stages of the water cycle by completing 3 activities. To help understanding of the water cycle your students can observe evaporation, the formation of frost, vapor and water and the process of distillation which is used to...

Through inquiry, experimentation, and observation, young scientists see how an increase in rainfall under climate change can affect the water table and soil salinity underground. Young scientists build models that represent the...

This particular lesson was written by the National Earth Science Teachers Association, but density is a concept that you can teach at the beginning of the school year in your life, physical, or earth science classes. It would be fun to...

From solid to liquid and then back again. Young scientists  dissolve salt in water and then evaporate the water while observing what happens to the solute. They use their observations to make predictions about other solutions.

Students perform an experiment to measure the density of tap water vs. salt water.

The basic elements of the water cycle and how water is recycled through our environment is focused on in this lesson. Your students construct classroom terrariums and learn to make and record observations relating to the water cycle....

Compare heating and cooling rates of different land forms. A lab activity has groups collect data on the rate of heating and cooling of soil, grass, saltwater, fresh water, and sand. An analysis of the rates shows how the different land...

Students complete activities where they observe the amount of freshwater in the world as a fraction of the actual amount of water using different mixtures. For this freshwater lesson plan, students brainstorm on how to preserve...

Using your senses, apprehend the effects of contaminants in water. With a global focus, young scientists conduct a safe experiment by tasting sugar and salt water with different dilutions. After reviewing threshold limits, learners write...

Scholars discover the amount of the Earth's water in various locations such as the ocean, ice, the atmosphere, etc. They then make a model of the how much water those percentages represent. Finally, analysis questions bring the concepts...

Young scientists investigate chemical and physical changes to the states of matter—gas, liquid, and solid—as well as solutions and suspensions with a variety of demonstrations, grand conversation, and an interactive quiz to check for...

Individuals explore solubility by modeling how water dissolves salts. They then view a video and compare how well water and alcohol dissolve salts, relating their comparisons to the structure of each molecule. 

After a whole-class discussion of water reservoirs, ten liters of water are given to each lab group to represent Earth's total amount of water. They divide the water into smaller containers, each representing one of those reservoirs. The...

What did one titration say to the other titration? We should meet at the end point! Young chemists perform four experiments: dilute solution, neutralization, titration, and figuring pH/pOH. 

Now it becomes crystal clear why the unit is called Mixtures and Solutions. The fifth installment of a six-part unit explores mixtures and solutions. After viewing a demonstration on mixing pebbles with water, salt with water, and...

Earth's vast ocean is full of mysteries! Science scholars discover the big-picture properties that influence its characteristics at different latitudes using a lesson from PBS's Weather and Climate series. After completing a background...

Students see how the properties of salt affect the color of flame, the flow of electricity, and the freezing temperature of water. They identify salt and sugar crystals under a microscope and discuss various practical uses of salt.

Using cabbage juice as a pH indicator, future scientists explore the effect of increasing carbon dioxide on the pH of the ocean and relate it to the health of coral reefs. Ideal for an earth or environmental sciences course, this lesson...

Students explore salt and fresh water. In this water lesson, students investigate the amount of Earth covered by water. Students compare the amounts of salt water to fresh water. Students create a visual representation to aid comprehension.

Students explore water and determine whether or not it is safe to drink. For this water exploration lesson, students are split into groups, to acts as the polluter, taster, and recorder. Students explore by placing different amounts of...

Students discuss certain properties of salt and how it is used every day as well as harmful uses. They experiment with salt to see it conduct electricity, form crystals and water freezing temperature. They complete a worksheet to record...

Students examine how climate affects lifestyle, clothing choices, food, and water sources. They explore climatic regions such as tropical, desert, coastal, and alpine situations. They look at the longitude and latitude, land features and...
