Students explore latent heat and how it relates to clouds in the atmosphere.  For this earth science lesson students investigate how clouds are formed. Students examine clouds and the water cycle.

High schoolers measure and record the mass of the nut to be tested to the nearest 0.01 gram.

Eighth graders examine the various methods of generating electricity and explain their commonalities. They determine what is the most common source of energy and what are the potential environmental health hazards due to electrical...

Students write a balanced chemical reaction. They articulate how burning fossil fuels increase the carbon dioxide levels in the atmosphere. Students incorporate all the environmental risks involved as well.

High schoolers recognize that global winds move in specific directions in specific latitudes and describe that in a written form. They relate the motion of the wind belts to historical navigation.

High schoolers describe the process of transesterification utilizing chemical formulas. They construct and compare models of chemical structure of the substances involved in biodiesel production such as: alcohols, alkenes, alkanes,...

Learners observe the interactions of chlorophyll and light. They develop and form their own testable hypotheses. Students predict the color of chlorophyll in various types of plants.

Young scholars observe a teacher demo on how clouds form. In this earth science lesson, students discover how cloudiness affects relative humidity. They explain the scattering of light by clouds.

In this science worksheet, students participate in an Earth Day activity by completing a crossword puzzle. Students read each clue. The answer which fits in the puzzle is provided in a scrambled word form. Students unscramble the words...

For this metabolism test review, students define several terms. Students write balanced chemical equations for aerobic cellular respiration. Students complete several multiple choice questions.

In this atoms and sugar molecules worksheet, students are given the structural composition of the sugar molecule maltose. They determine the number of each type of atom in the molecule, they find the ratio of hydrogen to oxygen atoms and...

Students explore oxygen and its physical and chemical propeties.  In this investigative lesson students complete several experiments using oxygen.

Sixth graders use paper cups, black and white lining, thermometers and plastic wrap to conduct an experiment that measures the energy-collecting capacity of various colors. They graph the results.

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.

Students determine

Tenth graders write and balance chemical equations and make a PowerPoint presentation on synthesis reactions.

Young scholars discuss what the m in E=mc2 represent. They relate that mass in a chemical reaction is always conserved. Students convey that atoms rearrange themselves in chemical reactions to form different molecules and compounds.

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

Pupils perform an experiment in which they put different types of salts in a balloon, fill it with hydrogen gas, and ignite it. The electrons in the salt molecules are excited by the heat and release energy in the form of light. ...

Students participate in biology demos. In this biology lesson, students explain how energy is released in the ATP cycle. They demonstrate DNA replication process.

Students create illustrated plastic plate designs depicting a physical, chemical, or biological change of some kind after investigating the artwork of porcelain artist Kataro Shirayamadani.

Students explore how coal is formed. They then discuss the information and answer any questions that they may have on the formation of coal. Students then answer questions in reference to the coal discussion and reading.

Students observe water birds feeding at a local wetland, record what they see, and construct an appropriate menu for a "Waterfowl Cafe." They also play a "flocking" game.

In the 19th activity of 22, learners determine if distance from a light source affects photosynthesis. Participants capture oxygen in straws and find that the amount of water the gas displaces is proportional to the rate of photosynthesis.
