Tenth graders observe the processes of evaporation, condensation, melting, freezing, boiling, and sublimation. They do a quantitative investigation of the freezing of water, to explore explanations that involve particles.

High schoolers observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other...

Fourth graders collect data on leaves collected, observe different species of leaves, and implement different methods of leaf preservation.

Students discover how flight is possible.  In this physics lesson, students investigate the properties of a blimp and gyro-copter, comparing rotating wings and fixed wings of aircraft.  Students create their own model aircraft...

Students investigate the water cycle. In this water cycle instructional activity, students create an ecosystem within a 2-liter bottle. Students record scientific observations as they observe the water cycle within their ecosystem.

Young scholars observe and record botanical details from the plant specimens. They identify plants using sorting key and field guide and classify specimens for preservation and display purposes.

Students investigate the age of the earth by using accepted scientific methods. They conduct research about the use of radioactive dating and there is a simulation activity of the process. Finally, students measure the radioactive decay...

Fifth graders conduct flight experiments.  In this uplifting experience lesson, 5th graders build an airfoil and place in a variety of conditions to observe the results of lift and force in flight, as well as angle of attack....

Students construct a thermoscreen for the experiment. In this earth science lesson, students make observations and interpret them using synoptic codes. They predict the weather based on gathered information.

Students study the concepts of polymerization and the function of crosslinkage.  In this polymer lesson students complete a lab activity and write down their observations. 

Students complete all of the steps in the scientific inquiry process to study Earth's energy cycle; most specifically temperature and the effects of albedo (energy reflected back from Earth's surface) on temperature.

Seventh graders take an outdoor observation walk around the campus and take soil samples. Working in groups , they conduct experiments with rocks and soil that demonstrate the effects of different types of erosion.

Students examine uses for estimating, and round purchase prices to estimate total purchases in a simulated school store setting. They discuss what it means for an item to be on sale, and observe the teacher work through the process of...

Fifth graders explore the concept of environmental management.  In this ecosystem lesson plan, 5th graders discover how models help scientists learn more about managing ecosystems. Students create their own model, make observations...

Third graders view photos of machines that measure wind energy and chart what they observe in the pictures and the questions they have about the pictures.  For this wind energy lesson, 3rd graders make a pinwheel.  Students...

Third graders identify the different parts of the sun. In this astronomy lesson, 3rd graders examine how the sun's energy drive life processes on Earth. They construct a model of a solar system using large rolls of toilet paper.

Young scholars identify the main parts of a seed. In this biology activity, students explain the factors needed for the seed to grow. They record observations everyday and report findings to class.

Students compare and contrast objects and are introduced to a Venn Diagram. In this alike and different lesson, students make observations regarding properties of objects. Students classify object and build ideas about variables....

Students discover the many different animals within various habitats and discover how each individual species interacts with its particular environment. Through charting different animals and their distinct habitat and matching animals...

Are you looking for lab sheets to go with your class experiment on plant response to light? You are no longer in the dark! This is a lesson that was written for a unit on light, but could easily be used to demonstrate plant behaviors in...

As an introduction to the hypothesis and testing method of investigation, young history detectives engage in a special investigation of a family artifact. After watching a short video that demonstrates the method, they develop a...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

With the use of a model rocket kit, aspiring aerospace engineers work cooperatively to construct and launch a rocket. A preparatory reading assignment is included, covering Newton's laws of motion and information about the first...

Why are Torrey pines only found in La Jolla, California and on Santa Rosa Island? Class members examine images of Torrey pines from these two locations, noting the similarities and differences, and then develop a demonstration model that...
