Although there are only 16 questions here, this chemistry handout makes a terrific unit assessment. It queries youngsters on the properties of ionic and covalent compounds, relates bond length tho stability and enrgy, compares polar and...

A very neat activity has been produced by Pearson Education, Inc. for use in a general chemistry class. The first nine questions are fill in the blanks for a paragraph about types of bonds and electronegativity. Five true-false questions...

There are many factors that affect how fast the glaciers are melting. A lab investigation has learners examine how the surrounding water affect the rate glaciers melt. They collect data from two samples of ice to determine how quickly...

The inside of the spacecraft Messenger, which explores Mercury, will experience temperatures from 32 to 91 degrees Fahrenheit. In the final installment of a series of four space-related activities, groups spend time discussing and...

The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...

Students observe physical change of melting by observing substance in original state, melting substance, allowing substance to return to original temperature, determining if substance retained its original properties, and recording results.

Immerse your chemistry class in the world of organic chemistry! Science scholars isolate acetaminophen from an over-the-counter sample during an intense and interesting lab. Groups use many different separation and analysis techniques to...

The laws of thermodynamics raise the temperature in your classroom when physics pupils complete this worksheet! They demonstrate their understanding by calculating specific heat capacity, final temperature, amount of work done, and more....

Science learners simulate what happens when ice breaks up and floats on water and how increased pressure on ice causes it to melt faster. They view a clip from the movie, The Day After Tomorrow, and relate their lab activities to what...

Apply robotics to connect physical properties to chemical properties. Future engineers use robots to determine the melting points of various fats and oils. The robots can do this by measuring the translucency of the fats as they heat up.

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...

A micro-unit on the phase changes of water includes three laboratory activities. Junior scientists compare the densities of ice and water, and then they do the same for cold and warm water. They examine freezing and boiling temperatures....

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...

In this chemistry worksheet, students identify the types of intermolecular forces for 5 different compounds then rank compounds by increasing melting point for 3 additional questions.

A remotely operated vehicle approaching a volcano was engulfed by molten sulfur where the plumes of fluids contained the highest concentrations of aluminum ever recorded. This isn't science fiction or an April fools joke, though it did...

For anyone learning or teaching chemistry, nothing beats a free and interactive periodic table of the elements. Peruse the elements while learning about atomic number and mass, melting and boiling points, and many other properties of...

Here is a good learning exercise for 5th grade scientists. In it, they look at a bar graph that shows the freezing point for a variety of liquids. Then, they are given a scenario of a certain liquid melting and freezing, and must...

Is losing cultural traditions the cost of social progress, or should people make stronger efforts to preserve these traditions? High schoolers watch a short film about the native Yup'ik people in Alaska and how they handle the shifts in...

In this elements worksheet, students complete a graphic organizer by comparing the elements' melting point, boiling point, density, and electronic configuration. Students determine the characteristics of Group 7 elements. This worksheet...

Radioactive decay, pH, properties of elements, organic compounds, and stoichiometry are all touched upon through this practice chemistry exam. It always helps learners to take a practice test in preparation for the actual exam. This...

In this freezing and boiling point graph learning exercise, students use the graph illustrated to respond to several questions that follow. They identify what is the freezing, boiling, and melting point of the substance in the graph....

We all scream for ice cream! Individuals create home-made ice cream in the classroom. This is a delicious way to show a real-world application of the freezing point depression to your class.

Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...

Chemistry calculations can look a bit like alphabet soup at times. How do you help pupils make sense of it all? An interactive resource helps scholars sort through the symbols for common quantities such as moles, boiling point, and...
