Students explore several parts of the body system in the eight lessons of this unit. Through several hands-on activities, the skeletal, muscular, digestive, circulatory and nervous systems are observed.

Students understand the process of bacterial transformation through experimentation. They describe the function of two important genes of the pBestLuc plasmid. They explain how to induce competence in E. coli cells.

Students illustrate paramagnetic and diamagnetic differences due to the unfilled and filled valence shells. They prepare saturated solutions and place into test tubes.

Students investigate hydrothermal vents by observing a simple model designed to show that hot water rises when it's heated. First, students listen as the teacher explains hydrothermal fluids and vents. Students watch as the teacher...

Students read about how burning coal affects the environment. After students finish reading about how burning coal affects the environment they have a group discussion to discuss what they thought about the information.

Students identify the types of foods and snacks they eat for their lunch. In groups, they identify healthy foods along with unhealthy foods. They design a new lunch menu using only healthy food and identifying which food group they belong.

Students examine the greenhouse gases affecting the atmosphere. In groups, they participate in activities in which they examine the effects of heat on the atmosphere and phytoplankton. They research how the phytoplankton differ in warm...

In this thermodynamics worksheet, students review kinetic and potential energy, enthalpy, entropy, and standard hear of formation. This worksheet has 1 short answer and 5 problem solving questions.

Students gain experience in designing an experiment and use logic in selecting specific tests for unknowns. Students recognize the use of spreadsheets in helping one to make clear comparisons.

Students identify chromatography as method of separating the components of a liquid. Students discover that dyes are composed of more than one component in achieving a particular color in these lessons on paper chromatography.

Students study the teeth of living mammals and apply those skills to the interpretation of the diet of extinct animals.

Students witness effects of temperature on plants. They also change temperature from a Celsius or Fahrenheit thermometer.

Second graders hear a story about King Henry the Egg, Little D and the meat group. They act out the parts as the story is read aloud and complete a worksheet. They pantomime activities that use and build muscle

Learners investigate the steps in creating a brochure using information about milk and its health benefits. Using expository writing, an information packet is created with pictures of students wearing their milk moustaches.

Students investigate the traits that make them individuals. They study that natural items have traits that make them unique by looking at pecans. They make fingerprint animals which they use to design fingerprint cards.
