Differentiate between temperature and thermal energy. Your class will build a thermometer using simple materials and develop their own scale for measuring temperature. Discuss with your class and consider why engineers need to understand...

Stir chocolate drink mix into hot and cold water to see if there is a difference in how quickly it dissolves. Number three in a six-instructional activity unit on dissolving, this installment investigates the effect of temperature. If...

Examine the behavior of energy as water freezes and melts. An engaging activity provides a hands-on experience to learners. Collaborative groups collect data and analyze the graphs of the temperature of water as it freezes and then...

Actual stream water is analyzed in this environmental science activity. Participants measure water temperature and pH, and then survey the macroinvertebrates living in their samples. The data worksheet, troubleshooting tips, and...

Students create predictions on what they believe happen to reaction rates when temperature is raised. They use hot, cold, and room temperature water for this experiment and observe the differences. They graph their observations and...

Students investigate the role of temperature and salinity in determining seawater density. They use a Temperature-Salinity Diagram to examine the effects of mixing on density.

Students examine the differences between air temperature and ground temperature.  For this investigative lesson students find NASA data on the Internet and use it to create a graph. 

Students measure the temperature of three water sources. They collect data points every second for twenty five seconds for each sample using Lego Robolab temperature sensors, complete a worksheet, and analyze the data.

Students explore the water cycle. In this earth science lesson plan, students observe and measure water in a closed container and in an open container. Students record their observations and compare their sets of data to draw conclusions...

Students use DigiScope technology to investigate Daphinia, popularly known as water fleas. They design, conduct, and report on an experiment to determine the effects of varying water temperatures on the heartbeat rate of Daphnia.

Learners explore water and how it changes forms.  In this investigative lesson students participate in an activity that shows them how water changes form and what it looks and feels like. 

Sprouting scientists explore the concept of density by making mass and volume measurements for five different liquids. From these measurements, they calculate densities. They apply their learning to explain Galileo's thermometer works...

Pupils investigate the biological and chemical characteristics of water to determine where purple loosestrife occurs. They create data sheets to record water quality tests in several locations and work in groups to conduct the water...

Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

In collaborative groups, young ecologists measure the temperature, pH, and dissolved oxygen for three different freshwater samples. They examine each sample with a microscope and record observations on the microorganisms in the pond...

High schoolers obseve and compare molecular movement within water at various temperatures and of varying salinity. They discuss the movement of water on a larger scale which can affect the movement and concentrations of microbial...

Students observe and discuss what happens when water turns to ice and when ice turns into water. For this freezing and melting lesson plan, students observe ice and water and complete hands on activities that change their properties.

Students perform experiments in pairs to visualize the changes in water during freezing and melting. In this properties of water lesson, students use their senses and inquiry tools to understand the changes in state of water. Suggested...

Young scholars determine the validity of Charles' Law. In this Charles' Law lesson plan, students measure the volumes of a gas at two different temperatures. They determine the volume at a high temperature and predict using Charles' Law...

Learners observe water samples and measure the samples' water quality. Students develop their own criteria for measuring water quality and test for temperature, acidity, oxygen levels, turbidity, conductance, sediment and hardness.

Tenth graders observe the processes of evaporation, condensation, melting, freezing, boiling, and sublimation. They do a quantitative investigation of the freezing of water, to explore explanations that involve particles.

Students monitor a local creek. In this environmental water activity, students conduct an environmental study of a local creek by monitoring the temperature and water quality over a period of time, then submit data to the Global Water...

Fourth graders participate in a teacher-led discussion about temperature--hot and cold. Each group of students is assigned specific materials for their lab experiment. They record temperatures measured in their journals and then plot...

Students complete activities to learn about changing air temperature. In this air temperature lesson plan, students study various ways to measure air temperature and learn factors that influence temperature. Students study the weather in...
