First graders study, observe, and use a simple machine. They study necessary safety and review posted safety rules related to using a machine and identify strategies for reporting any accidents or injuries.

Fifth graders study how simple machines can help us alter forces and discuss the term mechanical advantage. They then identify dysfunctional simple machines and discuss in groups how the dysfunctions will decrease the effectiveness of each.

First graders explore the specific needs, characteristics, and uses of plants. They discuss the needs of plants as they grow. Students observe plants in various settings as they grow and note the changes they see.

Eighth graders examine how electricity is produced in relation to the atom as well as what causes electric current to flow and what determines how much current flows through a circuit. These and other concepts of transformation of energy...

Sixth graders study about alternate energy sources and discuss with their neighbor how alternative energy sources affect environmental conditions so that an entire species could be affected.

Students work with data from a seismic wave model in a freely available GIS (geographic information system) program, ArcVoyager SE. Using a GIS, they examine maps and produce graphs to explore variations in seismic wave velocities at...

Pupils color the lightning part of the thunder cloud and then cut out the pattern. They then cut out the cloud pattern and put cotton onto it with glue. They then fold a piece of paper several times to create a snowflake to which they...

Students identify how to relate the position of an element in the periodic table to its atomic number and atomic mass. They identify how to use the periodic table to identify metals, semimetals, nonmetals, and halogens, and also,...

Students participate in paper recycling. They are taught to environmental awareness of recycling and its importance in their future. Students discuss and identify the problems of how they can minimize waste. They brainstorm suggestions...

Eleventh graders analyze photographs representing leisure and transition during a global conflict. Working in groups, 11th graders review pictures from a web exhibit. The group completes a graphic organizer analyzing the photograph for...

Students use a computer and math to complete a science project. They review a brief history of computers as well as information on different operating formats will be included. In addition, students complete an overview of the hardware...

Students investigate the length of various objects. In this measurement lesson plan, students convert one metric unit to another. They explain the importance of a uniform system of measurement.

Students research any topic relating to the National Oceanic and Atmospheric Administration (NOAA) research cruise that Mrs. Richards be participating in.

Tenth graders identify native plants of North Dakota. They compare the plants found on native prairie with the plants described in the Lewis and Clark journals. They present the information they have collected in an electronic format...

Pupils study Charles Darwin's voyage on the HMS Beagle and his visit to the Gal??pagos Islands. They click through an interactive map of the Gal??pagos Islands to read actual and fictional journal entries from a fellow eco-tourist.

Students participate in an experiment to define a parts-per-billion solution. For this ecology lesson, students select a second substance to create a parts-per-billion solution and observe and record their results. Students work in...

[Free Registration/Login may be required to access all resource tools.] Explains scientific theories and introduces several famous theories in biology.

[Free Registration/Login may be required to access all resource tools.] Nature of scientific theories, examples of physical science theories, and the law of parsimony.

[Free Registration/Login may be required to access all resource tools.] Students will understand the difference between theories, hypotheses, and laws in science.

Given laboratory investigation scenarios, students will distinguish between scientific hypotheses and scientific theories.

This brief review explains that a scientific theory comes from testing an idea.

By the end of this section, you will be able to explain how the methods of science are used to make scientific discoveries; define a scientific model and describe examples of physical and mathematical models used in physics; and compare...
