Fourth graders identify a physical change as one that results in a change in size, shape, or state of matter. After an initial teacher-led discussion and demonstration, groups of students get together to perform an experiment which...

In this earth science worksheet, students use the clues given at the bottom of the sheet to solve the crossword puzzle related to weather. They identify various cloud types and how they are formed. Students also identify atmospheric...

Middle school chemists visit interactive websites in order to discover what happens to molecular motion when heat is added to matter. They conduct an experiment that demonstrates the expansion of matter with the addition of heat. A lab...

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...

Characteristics of each state of matter are listed, the formulas for heating water are detailed, and values for boiling and heat of vaporization are presented. This simple slide show provides direct instruction as well as practice...

Students view and analyze buoy, satellite, temperature vs depth data to study about ocean circulation and how is related to atmospheric circulation. They read and interpret satellite image data related to: Surface wind speeds, Wave...

In this colligative properties worksheet, students solve eight problems. They calculate molarity, molality and grams of substances in addition to using colligative properties to calculate solutions.

In this water desalinization worksheet, students will design and construct their own desalinization plant. Then they will describe how they set up their experiment and if it worked or not.

In this transpiration activity, students will conduct an experiment to measure the rate of transpiration from a plant by measuring how much weight the plant loses over 5 days. Students will record their data and create a graph of the...

Students simulate the water cycle. In this water cycle lesson, students create a model of the water cycle. Students draw the water cycle and write a paragraph explaining their drawing.

Blow your class away with a gust of humor as they watch this video about air pressure and wind. Along the way, they find that the density of air (as determined by temperature, altitude, and water vapor content) leads to air pressure...

I'm so cool! No, you're exothermic. This thermodynamics lab unit includes an introduction, teacher demonstrations, six labs that students rotate through each class day, homework assignments, application of knowledge, and...

Students are introduced to the analysis of health risks in the laboratory, particularly from vapors from organic solvents. They consider quantitative measure of risk such as threshold limit values (TLVs), the amount of the compound that...

Students participate in a demonstration to show the change of water vapor to a liquid. They discuss the three states of matter. They examine flash flood safety to end the lesson.

In this chemistry practice worksheet, students select the correct response to the given questions. Students apply knowledge about the states of matter, finding vapor pressure and atmospheric pressure.

Students explain how water changes from vapor to liquid with a change in temperature by engaging in this experiment. They use a worksheet imbedded in this lesson to guide their inquiry.

In this thermochemistry activity, students calculate the enthalpy of vaporization as well as the write the thermochemical expression for the production of the chemical reaction.

Learners investigate the 3 states of matter. In this physical science "matter" lesson plan, students observe and participate in a number of demonstrations involving melting and freezing water. Learners observe the effect heat has on...

Introduce middle school science learners to condensation with this presentation. It begins with a brief explanation of the process and humidity, but does not present all of the details. Three demonstrations need to be set up ahead of...

Students determine the heat energy needed to vaporize (boil) one gram of liquid nitrogen.

Students observe methods by which air can crush aluminum cans. As water in the can boils and is sealed, the can collapses as it cools. When the procedure is reversed, the can expands to its original shape. After the alternate experiment,...

Students investigate the factors affecting climate using Live Access Server. For this geography lesson, students graph atmospheric data using Excel spreadsheet. They compare and contrast temperature, precipitation and water vapor of two...

Students determine how much moisture in the air affects the diurnal temperature range. They investigate to determine the different climatological regimes of both the Southern Plains and the world. and greenhouse gases effect the earth's...

When you have a cold drink and you notice the water forming on the outside, it is literally pulling the water from the surrounding air to form the condensation. After watching a demonstration of condensation forming on a glass,...
