Middle schoolers observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water

Students discuss the different types of climate zones found throughout the world. They participate in activities which relate to real events. They make observations and the consequences of their actions on the environment.

A great way to learn about molecular structures is to make a model. Gumdrops and toothpicks are used to construct crystal models. The models are based on theories of crystal shapes that occur because of positive and or negatively charged...

What would it be like to be stranded on Mount Everest? Curious learners view a video clip, test common fabrics to see how they stand up to cold, and develop/answer discussion questions. 

Students participate in lab activities in which they examine immersion, stain resistance, and stress cracking of synthetic polymers. Students use their collected data to discuss service applications and possible performance of materials.

Second graders examine the interdependence of organisms using the book "Go To Sleep, Gecko!" They examine a variety of food chains, listen to the book, and answer story comprehension questions. Students then conduct research on food...

Ecology aces examine sea surface temperature maps and relate temperatures to concentration in fish and zooplankton populations. Take your class to a computer lab and provide experience with actual remote sensing data. Some of the links...

Learners are exposed to the variety of ways in which scientist use remote sensing and it used in everyday life. They investigate about zooplankton and fish. Students list the two important groups of organisms in both aquatic and marine...

Students observe a demonstration of how melting snow and ice can contribute to mudflows. They then observea list of continents with the number of snow and ice covered mountains on each continent and discuss. They then label a group of...

For this chemistry worksheet, students respond to several multiple choice questions relating to bonding and acid-bases. They also identify the various types of bases and how they differ from each other.

In this substitution and elimination reactions worksheet, students complete 11 reactions by writing the structural formulas for the products. If no reaction occurs, they write N.R. They also write structures of the products for 3...

In this substitution and elimination reactions worksheet, students compete reactions by drawing the structural formulas for 18 reactions. If no reaction occurs, students write N.R.

Environmental science classes read articles about two different scientific studies. One is about the effects of contraceptive chemicals on fertility, and the other is about how a pesticide may be reducing bone density in exposed...

Students examine an environmental issue. In this global studies lesson plan, students read an article entitled, "Global Climate Change," and respond to the discussion questions that accompany it.

Students use satellite data to compare precipitation and surface temperatures on different islands.  In this satellite lesson students create graphs and explain the differences between weather and climate.
