Students design an experiment to determine the best conditions for molds growth. In this biology lesson, students collect data for a week and analyze their findings. They create a presentation and share them with the class.

Students compare the weathering of different-sized materials. Comparisons are made and data analyzed to reach conclusions about the process of weathering. Applications can be made for the higher grades.

Students compare the weathering of materials. in this weathering lesson, students experiment with the chemical and physical weathering of different materials. Students use salt and water as an example of how weathering occurs.

In this heating and cooling curve worksheet, students use a given graph of a substance being heated from a solid to a liquid and then a gas over time. They use the graph to answer eleven questions about the phases of the substance and...

Students explore liquids and solids by conducting in class experiments. In this matter lesson, students define the properties of matter and how heat can change those properties. Students experiment with heating objects such as butter and...

Students investigate the process that occurs when liquids evaporaate. They test water and alcohol to determine which substance evaporates more quickly and relate the rate to energy changes.

Student Teachers are given the opportunity to examine how to use a computer-based laboratory for inquiry. The practice is done to teach future teachers how to use these tools so they can be ready for use in the classroom environment.

Students explore the life forms that live in the hot springs of Yellowstone. They examine how microscopic creatures can survive in these extreme conditions. Students perform experiments to observe growth samples and demonstrate how a...

In this science worksheet, students locate and identify various vocabulary terms related to earth science. There are 44 words/phrases located in the puzzle.

For this chemistry overview worksheet, students review stoichiometry, states of matter, thermochemistry, gas laws, chemical bonding, molarity, chemical equilibria, and kinetics. This worksheet has 41 problems to solve.

Third graders identify a cloud and explore how they form. They create an acrostic poem about clouds.

Students recognize positive and negative numbers and perform mathematical functions.

Students categorize items into one of the three states of matter. They participate in a demonstration in which they represent particles of matter. Finally, they complete an experiment in which they "race" top see who can make acetone...

In this heat activity, students determine the heat gained or lost when matter changes phases. Students review the energy flow through ecosystems by comparing trophic levels and food webs. This activity has 10 fill in the blank, 5 short...

For this science:  water quiz worksheet, students answer twenty questions, not interactively about the properties of water, then scroll down to check their answers.

In this activity, students can use an EasyTemp probe to measure the temperature of hot water and determine its boiling temperature. EasyData is needed for this activity.

An Internet project designed to determine the greatest influence on the boiling point. After reading the project instructions and performing the experiment, submit your data and compare your results to other classes from around the world.

This video tutorial reviews the freezing point and boiling point constants of water. [1:19]

You know that water can exist in three separate phases: solid (ice), liquid (water), and vapor (steam). To change from one phase to another, you simply add (or remove) heat. When water boils, what happens to molecules (for example sugar...

Mars has such low atmospheric pressure that any water at the surface would boil away. In this activity, students see that they can get water to boil below its "typical" boiling temperature when they drop the pressure in a closed...

A module reviewing over how vaporization occurs and its difference from evaporation. Also, review over the definition of boiling point. Module includes a video, pictures, explanation, and review questions.

Control the temperature and observe the impact on the motion and interactions between particles. Compare the interactions between nonpolar molecules and between polar molecules to see how polarity affects the boiling point of substances...

The temperature at which substances boil is determined by intermolecular attractions. Explore how these forces affect a substance's boiling point.

A scientific explanation of what a boiling point is, the factors that can alter a liquid's boiling point, changes of state that occur at the boiling point, and how the normal boiling point relates to a liquid's vapor pressure. (Updated:...
