In this lab-based activity the students will use their knowledge about the law of conservation of energy to explain the loss of heat by warm water to cold water. Then, the students will use these concepts to design and carry an experiment to determine the unknown temperature of a hot water sample.

This article reprints and links to informational text about the adaptations that allow mammals and fish to survive in polar oceans. Versions are available for students in grades K-1, 2-3 and 4-5. Related science and literacy activities are included.

In this experiment, two chemicals that can be found around the house will be mixed within a plastic baggie, and several chemical changes will be observed.

Experiment with a helium balloon, a hot air balloon, or a rigid sphere filled with different gases. Discover what makes some balloons float and others sink.

CK-12 Basic Physics - Second Edition updates CK-12 Basic Physics and is intended to be used as one small part of a multifaceted strategy to teach physics conceptually and mathematically.

Watch water boil at room temperature. The temperature at which water boils depends on pressure. You can demonstrate this by dramatically lowering the pressure on a water-filled plastic syringe at room temperature.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current. Because of safety concerns, this activity should be conducted as a demonstration only and learners should be kept at a safe distance.

This investigation will have students testing how heating and cooling can change the state of matter. They will test a variety of materials determine whether a change takes place through heating/cooling.

This activity is a 2 part lab activity where students record properties of various bars of soap, and make models of molecules as they are cooled or heated. Students develop a new experiment changing one variable.

This article lists common misconceptions about light, heat, and the sun. It provides formative assessment probes and information about teaching for conceptual change.

Elementary grade students investigate heat transfer in this activity to design and build a solar oven, then test its effectiveness using a temperature sensor. It blends the hands-on activity with digital graphing tools that allow kids to easily plot and share their data. Included in the package are illustrated procedures and extension activities. Note Requirements: This lesson requires a "VernierGo" temperature sensing device, available for ~ $40. This item is part of the Concord Consortium, a nonprofit research and development organization dedicated to transforming education through technology. The Consortium develops digital learning innovations for science, mathematics, and engineering.

With the help of simple, teacher-led demonstration activities, students learn the basic concepts of heat transfer by means of conduction, convection, and radiation. Students then apply these concepts as they work in teams to solve two problems. One problem requires that they maintain the warm temperature of one soda can filled with water at approximately body temperature, and the other problem is to cause an identical soda can of warm water to cool as much as possible during the same thirty-minute time interval. Students design their solutions using only common, everyday materials. They record the water temperatures in their two soda cans every five minutes, and prepare line graphs in order to visually compare their results to the temperature of an unaltered control can of water.

The author explains heat transfer and how it applies to living in extremely cold environments.

The phenomenon is thermal expansion of copper. This demonstration allows an observer to see the effect of heating (and cooling) a copper tube. When heated, the copper tube lengthens and thickens. When cooled, the tube shrinks. The lengthening of the rod rotates a toothpick with an attached flag to make the expansion visible and measurable.

The students discover the basics of heat transfer in this activity by constructing a constant pressure calorimeter to determine the heat of solution of potassium chloride in water. They first predict the amount of heat consumed by the reaction using analytical techniques. Then they calculate the specific heat of water using tabulated data, and use this information to predict the temperature change. Next, the students will design and build a calorimeter and then determine its specific heat. After determining the predicted heat lost to the device, students will test the heat of solution. The heat given off by the reaction can be calculated from the change in temperature of the water using an equation of heat transfer. They will compare this with the value they predicted with their calculations, and then finish by discussing the error and its sources, and identifying how to improve their design to minimize these errors.

This activity is an entire-class lab experiment that refreshes the concepts of sinking and floating, while introducing the concepts of bouyancy and density using the fizz from sprite (carbon dioxide gas) and raisins.

In this activity, students will test whether the color of a material affects how much heat it absorbs.

The students participate in many demonstrations during the first day of this lesson to learn basic concepts related to the forms and states of energy. This knowledge is then applied the second day as they assess various everyday objects to determine what forms of energy are transformed to accomplish the object's intended task. The students use block diagrams to illustrate the form and state of energy flowing into and out of the process.

Demonstrations explain the concepts of energy forms (sound, chemical, radiant [light], electrical, atomic [nuclear], mechanical, thermal [heat]) and states (potential, kinetic).

This lesson covers concepts of energy and energy transfer utilizing energy transfer in musical instruments as an example. More specifically, the lesson explains the two different ways in which energy can be transferred between a system and its environment. The law of conservation of energy will also be taught. Example systems will be presented to students (two cars on a track and a tennis ball falling to the ground) and students will be asked to make predictions and explain the energy transfer mechanisms. The engineering focus comes in clearly in the associated activity when students are asked to apply the fundamental concepts of the lesson to design a musical instrument. The systems analyzed in the lesson should help a great deal in terms of discussing how to apply conservation of energy and energy transfer to make things.
