Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

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...

In this basics of science worksheet, learners review the metric system, the difference between homogenous and heterogenous mixtures, the scientific method, and science lab first aid. This worksheet has 15 short answer, 43 fill in the...

This very thorough lesson plan has students collect all ingredients necessary and work in pairs to make ice cream using plastic bags. They take temperature readings and record them on the chart as well as record findings on the...

Do charged and neutral particles behave differently as they undergo phase changes? Science sleuths examine two types of attractive forces using an informative interactive. Pupils can vary the amount of Van der Waals attraction present...

Ever wonder how fish survive in freezing cold water—especially Antarctic waters? Some fish have an adaptation that lowers the freezing point of their life fluids. Learners model these adaptations in two lab explorations. The first...

Students explore physical and chemical changes. In this chemistry lesson plan, students will go outside to observe changes seen in nature. Students will then work in the lab to identify changes at different stations prior to doing a...

Students compare the freezing temperature of two substances by conducting an experiment to freeze liquid ice cream. They vary the amount of salt used in the ice cubes during the freezing procedure to determine the change in the...

In this wet dry ice worksheet, students read the information about dry ice and phase change. Students perform an experiment in which they observe phase changes of ice. Students answer analysis questions as it relates to the phase change...

Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

Open this instructional activity by giving a brief history of ice cream. Using liquid nitrogen to lower the temperature, preteens make their own confection. The accompanying activity sheet queries learners about freezing point, the...

In this observation worksheet, scientists observe a burning candle and answer eight post-lab questions. Topics include the phase changes occurring during the observations, the role each part of the candle plays in the chemical reaction,...

Ninth graders discover the reasoning behind spraying water on fruit and seedlings in preparation for hard freezes. In this conceptual physics lesson, 9th graders conduct an experiment to measure the heat released when water goes from a...

It's time to increase the heat! Young chemists demonstrate heat transfer and heat capacity in an activity-packed lab, showing the transitions between solid, liquid, and gaseous phases of materials. Individuals plot data as the...

How much does your class know about the relationship between climate change and carbon dioxide? Science scholars explore the nature of greenhouse gases and rising ocean temperature through demonstrations, research, and experiments. The...

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

Go to extremes to illustrate boiling point! Junior chemists explore the effects of heating and cooling on polar and non-polar substances. The interactive allows users to raise and lower the temperature, set specific temperatures, and...

This is actually a 10-day mini unit on thermal energy for your high school chemists. Every avenue is taken to get learners absorbed in heat: a pretest, a PowerPoint presentation, Internet exploration, demonstrations, lab activities, and...

There's more to fluids than meet the eye—they include gases, liquids, and polymers, too! Scholars complete three hands-on activities exploring different properties of fluids. They explore viscosity by measuring the resistance, or...

High schoolers investigate condensation in the lab. For this chemistry lesson, students explain molecular motion during phase changes. They relate this observation to Earth's weather conditions.

Eighth graders investigate different gas behaviors. In this chemistry lesson, 8th graders describe how changing volume and temperature affect gas particles motion. They collect data and make a generalization about these variables'...

High schoolers investigate the effects of adding or removing a reactant or a product on chemical equilibrium. In this equilibrium lesson plan, students add or remove ions to solutions to determine the effects on equilibrium. They make...

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.

Astronomy is literally over your head, but this lesson will explain how we study it. Young scientists make telescopes, calculate and compare the light gathering power of lenses, and simulate detection of infared radiation....
