Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

Students place words describing a range from cold to hot on a scale. Using those words, they identify places on Earth which are cold, hot, freezing or boiling. They practice using and reading a thermometer with three different beakers...

Learners calibrate an alcohol thermometer using the boiling and freezing point of water. In this physical science lesson, students explain what happens to boiling point of water as altitude increases. They calculate their experimental...

In this chemical solutions instructional activity, students determine the molecular weight of a substance, determine the boiling and freezing point of solutions, and determine molarity of a solution. This instructional activity has 3...

This is a great worksheet with an infographic to assist your high schoolers in categorizing matter into mixtures and non-mixtures. Information is given about the metric system of measurement. Your young students match 13 terms with their...

Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...

An extremely thorough presentation walks new chemists through the basics of matter. There really isn't a unifying theme, however So many topics are covered: forces, elements, atomic structure, chemical properties, compounds, quarks,...

Who can grow the best crystals? Challenge class members to develop strategies for enhancing growth in the crystals. Through a lab investigation, learners study the properties of crystals and test the effectiveness of different...

Students recognize the concept of temperature, including degrees, and the melting and freezing process. In this 1st - 2nd grade lesson plan, students identify the temperature of various objects, as well as create their own paper...

In this Kelvin scale worksheet, high schoolers read about the relationship between the Celsius scale and the Kelvin scale. They are given the equations to convert from one scale to the other. They find the equivalents for temperatures...

Students distinguish between physical changes and chemical changes. They comprehend that chemical reactions produce new substances with compositions and properites which are different than those of the starting materials. Pupils also...

Students focus on stellar luminosities to estimate size of habitable zones, map out habitable zone around hot light bulbs that serve as models of stars, investigate how size of model "habitable zone" around light bulbs depends on...

Third and fourth graders who are studying states of matter will enjoy this simple exercise. In it, they look at a picture of a girl in her kitchen, and they must circle five examples of materials that have changed states of matter as...

Students discuss the three states of matter and how they are affected by temperature. They make ice cream in a bag while observing how temperature change affects the mixture. They discuss why some specimens froze more quickly than others...

Investigate how temperature affects the density of water and stratification that occurs in bodies of water when temperatures vary. Water of differing temperatures is given different colors to see the layers that form. The lesson is meant...

Students explore the states of matter. They discuss the different phrases of matter and categorize everyday substances as solids, liquids, or gases. Students explore the relationship between the phases on an atomic level and the role of...

In this gases worksheet, students read about the Kelvin scale of temperature, they answer 3 fill in the blank questions about the relationship between temperature and pressure and they plot the temperature and pressure of gas samples at...

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 examine how to determine temperature on a thermometer. They read and discuss an informational handout, discuss examples of Fahrenheit and Celsius scales, and complete a worksheet.

Students identify the various states of water. They use hypothesizing and hands-on experimenting on changing the states of water, the properties of water, and the role of heating and cooling in the changes of state.

Students observe a demonstration on the role of thermal conductivity in heat transfer.  In this thermal conductivity lesson, students design and conduct an experiment to compare the thermal conductivity of four substances....

Eighth graders explore how to read a thermometer. They convert temperature between Celsius, Fahrenheit and Kelvin. Students explain that Celsius is used in the Scientific community and Fahrenheit is used basically only in the United...

Learners participate in experiments to visualize the differences between chemical and physical changes. They attempt to detect the five characteristics of a chemical change.

Students investigate molecule movement according to the kinetic molecular theory. In this kinetic molecular theory lesson plan, students observe demonstrations showing that molecules speed up with increasing temperature and slow down...
