Students are told that any object moving through a fluid (air, water, molasses, etc) experience a drag force which oppose the motion. They are given the summarized version of drag which is proportional to the square of the velocity....

In this environment instructional activity, students complete a crossword puzzle using the word bank and definitions for terms about the land and its water.

Students observe, measure and sort leaves.  In this leaf activity students divide into groups and observe the different kinds of leaves. 

Twelfth graders investigate the refractive index of water. In this physics lesson, 12th graders explain the operation of laser. They write a lab report about the activity.

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

Pupils observe the effects of water on four different packing materials to determine which ones are more soluble. They then decide which material would be a good packing material to use for the environment and which may be a bad choice...

Pupils simulate methods used to extend the effective life of an oil well by extracting less available oil. They identify techniques which can be used and evaluate their effectiveness. Pupils are introduced to rock size and temperature of...

Students identify the causes of hypothermia. In this biology lesson, students investigate the different types of heat transfer and heat loss. They discuss several practical measures to avoid hypothermia.

Fourth graders collect, record and analyze data using simple weather instruments or use weather resources to comprehend weather. They comprehend that scientists are very important people in today's world. Pupils look at cloud types to...

Students convert degrees between two different units. In this algebra lesson, students graph linear equations and identify the line of best fit. They use their line of best fit to make predictions given a set of data.

Students observe a demonstration on the role of thermal conductivity in heat transfer.  For this thermal conductivity lesson, students design and conduct an experiment to compare the thermal conductivity of four substances....

Students investigate what causes the heat on Earth.  In this Earth heating lesson plan, students experiment with different heat sources and determine where the Earth gathers the most heat.  Students explore vocabulary words...

Students examine estuaries in Delaware. They, in groups, gather samples of water to find organisms and identify them.

Students demonstrate that light and dark colored objects absorb the sun's radiation at different rates. They experiment with the temperature change of water in two locations and discuss the results.

Third graders continue their examination of the heat energy from machines. In groups, they make predictions on which machines might produce a measureable amount of heat. They take the temperatures of the various machines and record them...

Students observe the process of transpiration in leaves. They measure how much water a leaf gives off in a 24-hour period, calculate the volume, and answer discussion questions.

Students discuss the relationships between dissolved oxygen in a stream, stream temperature, organic waste loads, and stream conditions by studying and using a model of dissolved oxygen in the stream.

Students view infrared images of a blowing hair dryer, a Popsicle, and a toaster. They discuss the images and ways they are different than visible light images. Students view a temperature scale and discuss which parts of the item are...

Students estimate the energy output of the sun. They estimate how much power sunlight the sunlight provides to the earth. They build a simple device to measure the amount of solar radiation the earth receives from the sun.

Students calculate the amount of food calories found in an individual peanut. In small groups, they set up the experiment so that a burning peanut will heat water above it. Using the temperature change and volume of the water they...

Learners determine the changes in different types of water in a sealed container over time. They investigate how to measure dissolved oxygen, temperature, and carbon dioxide with calculator or computer probe-ware. Students determine the...

Students quantify the relationship between temperature, energy and heat and define an endothermic reaction. They measure the energy change caused by dissolving one mole of ammonium nitrate in water.
