Wow! This is a nifty presentation for teaching high school chemists about the heating curve. It displays a graph for temperature vs. heat added, then enters the curve itself. The final slide identifies each part of the curve. Notes are...

Tenth graders examine the heating curve of water when head is added constantly over time. They input values into a calculator as they record water temperature every thirty seconds as it is heated on a hot plate. They complete the...

Examine the unique graphs coined broken-line graphs. Using the phase change of water for data, learners answer questions related to the temperature and energy at different times in the cycle of the phase change. Questions focus on the...

I scream, you scream, we all scream for ice cream! Even high schoolers enjoy making ice cream. This laboratory exercise has them record the temperature changes throughout the process of liquid becoming solid, graph the results, and...

Young scholars examine the three states of matter. They identify the segments of heating and cooling curves. Students analyze data and create a graph to determine the freezing and melting temperature of water.

Scientists have been studying exothermic reactions before they were cool. The lesson plan begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed...

Students experiment with a pure substance and a phase change. In this heating and cooling curves lesson plan, students study the effects of heating and cooling a pure substance to observe a phase change. They determine both the melting...

How well can your class concentrate on solutions? Scholars use colorimeter absorption to explore a starch concentration calibration curve. They add iodine to different starch solutions to see how the concentration of the solution changes.

Scholars learn about heat release in phase changes. They perform calculations as they compare and contrast a science fiction passage and a home heating application.

High schoolers differentiate the three states of matter. In this chemistry lesson, students analyze graphs of heating and cooling curve of water. They complete a lab report and discuss results.

In this calorimetry worksheet, students determine the change in enthalpy, sketch the heating curve, and determine the specific heat and heat of fusion for a given compound. This worksheet has 4 problems to solve.

Begin a full lesson on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep viewers at...

Learners investigate the concept of a filter. They use simple supplies in order to construct one after watching a demonstration performed by the teacher. An important warning that the project water is not clean for drinking is included....

Amateurs of alternative energy build a mini parabolic-trough solar energy collector and use it to heat water. Temperature is recorded over a three-minute period and the data is graphed and analyzed. Note that in order to paint aquarium...

This two-page assignment covers basic thermochemistry concepts. Chemistry learners identify exothermic and endothermic processes, explain a phase change graph, and draw an energy level diagram. There are no problems to solve, just...

Students investigate melting and freezing behavior in substances. In this melting and freezing points lesson plan, students perform experiments to test the impact of various salts on the freezing point of water, they test the impact of...

Using a colorful infographic handout and a guide sheet, hold a class discussion about how a bathtub can serve as a model for the greenhouse effect created by Earth's atmosphere. Participants will understand that as energy or matter is...

The learners construct a heating curve and explain its components. They perform calculations. They review phase changes and quantify Energy differences. They review phases of matter and their energy content.

Students are introduced to the laws of thermodynamics. The 1st law of thermodynamics states that the energy must be conserved when two objects of different temperatures come in contact. If one object gains energy, the other object must...

In this enthalpy of reactions learning exercise, students use a known amount of copper (II) sulphate solution and an excess of zinc powder to calculate the reaction's enthalpy change. Students measure the temperature change throughout...

Students describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...

In this surface water instructional activity, 6th graders will read 12 statements related to surface water and the movement of rivers over the land. In each statement, there is a bold-faced word that the students will unscramble and...

Learners are told that objects in contact with one another reach an equilibrium temperature. A hot object placed in a cool liquid always cool off. It never happens that the object gets hotter and cool liquid gets colder. Students predict...

In this matter worksheet, students review the states of matter and the gas law formulas and equations. Students then complete 7 multiple choice questions and 6 problems.
