Using paper, paper clips and tape, student teams design flying/falling devices to stay in the air as long as possible and land as close as possible to a given target. Student teams use the steps of the engineering design process to guide them through the initial conception, evaluation, testing and re-design stages. The activity culminates with a classroom competition and scoring to evaluate how each team's design performed.

Students act as civil engineers developing safe railways as a way to strengthen their understanding of parallel and intersecting lines. Using pieces of yarn to visually represent line segments, students lay down "train tracks" on a carpeted floor, and make guesses as to whether these segments are arranged in parallel or non-parallel fashion. Students then test their tracks by running two LEGO® MINDSTORMS® NXT robots to observe the consequences of their track designs, and make safety improvements. Robots on intersecting courses face imminent collision, while robots on parallel courses travel safely.

The difference between an architect and an engineer is sometimes confusing because their roles in building design can be similar. Students experience a bit of both professions by following a set of requirements and meeting given constraints as they create a model parking garage. They experience the engineering design process first-hand as they design, build and test their models. They draw a blueprint for their design, select the construction materials and budget their expenditures. They also test their structures for strength and find their maximum loads.

Parkinson's disease is a chronic, progressive, degenerative disease of the central nervous system that produces movement disorders and changes in executive functions, working memory, visuospatial functions, and internal control of attention in affected cognitive areas. It is named after James Parkinson (1755-1824), an English neurologist who studied the disease.

Students are presented with a short lesson on the Coulter principle—an electronic method to detect microscopic particles and determine their concentration in fluid. Depending on the focus of study, students can investigate the industrial and medical applications of particle detection, the physics of fluid flow and electric current through the apparatus, or the chemistry of the electrolytes used in the apparatus.

Students apply concepts of disease transmission to analyze infection data, either provided or created using Bluetooth-enabled Android devices. This data collection may include several cases, such as small static groups (representing historically rural areas), several roaming students (representing world-travelers), or one large, tightly knit group (representing urban populations). To explore the algorithms to a deeper degree, students may also design their own diseases using the App Inventor framework.

Students are introduced to passive solar design for buildings an approach that uses the sun's energy and the surrounding climate to provide natural heating and cooling. They learn about some of the disadvantages of conventional heating and cooling and how engineers incorporate passive solar designs into our buildings for improved efficiency.

Students engage in an interactive "hot potato" demonstration to gain an appreciation for the flow of electrons through a circuit. Students role play the different parts of a simple circuit and send small items representing electrons (paper or candy pieces) through the circuit.

In this activity, students will learn how water can be polluted by algal blooms. They will grow algae with different concentrations of fertilizer or nutrients and analyze their results as environmental engineers working to protect a local water resource.

In this activity students analyze a familys pedigrees to make a claim based on evidence about mode of inheritance of a lactose intolerance trait, determine the most likely inheritance pattern of a trait, and analyze variations in DNA to make a claim about which variants are associated with specific traits. This activity serves as a supplement to the film Got Lactose? The Co-evolution of Genes and Culture (http://www.hhmi.org/biointeractive/making-fittest-got-lactase-co-evolution-genes-and-culture). The film shows a scientist as he tracks down the genetic changes associated with the ability to digest lactose as adults. A detailed teachers guide that includes curriculum connections, teaching tips, time requirements, answer key and a student guide can be downloaded at http://www.hhmi.org/biointeractive/pedigrees-and-inheritance-lactose-intolerance. Six supporting resource and two click and learn activities are also found on the link.

Students investigate the property dependence between liquid and solid interfaces and determine observable differences in how liquids react to different solid surfaces. They compare copper pennies and plastic "coins" as the two test surfaces. Using an eye dropper to deliver various fluids onto the surfaces, students determine the volume and mass of a liquid that can sit on the surface. They use rulers, scales, equations of volume and area, and other methods of approximation and observation, to make their own graphical interpretations of trends. They apply what they learned to design two super-surfaces (from provided surface treatment materials) that arecapable of holding the most liquid by volume and by mass. Cost of materials is a parameter in their design decisions.

Experimental approaches to the study of the auditory periphery, presented through lectures by faculty and presentations of primary literature by students. Topics include: functional anatomy of the inner ear, transduction by hair cells, synaptic transmission, endocochlear potential, outer hair cells and their electromotility, responses of auditory nerve fibers, efferent control of cochlear function, inner-ear development, and damage and repair of hair-cell organs. Evaluations of students based on oral and written presentations, laboratory exercises, a final examination, and participation in discussions.

Students explore their peripheral vision by reading large letters on index cards. Then they repeat the experiment while looking through camera lenses, first a lens with a smaller focal length and then a lens with a larger focal length. Then they complete a worksheet and explain how the experiment helps them solve the challenge question introduced in lesson 1 of this unit.

Students investigate how different riparian ground covers, such as grass or pavement, affect river flooding. They learn about permeable and impermeable materials through the measurement how much water is absorbed by several different household materials in a model river. Students use what they learn to make recommendations for engineers developing permeable pavement. Also, they consider several different limitations for design in the context of a small community.

This chapter serves as an introductory overview of the subject. The chapter is accurate, relevant and clear. It is a technical reading that is best suited to nurses, nutritionists and other allied health professionals at both the undergraduate and graduate level.

PhD Science Grade Levels K–2 is available as downloadable PDFs. The OER consists of Teacher Editions and student Science Logbooks for every module. With PhD Science®, students explore science concepts through authentic phenomena and events—not fabricated versions—so students build concrete knowledge and solve real-world problems. Students drive the learning by asking questions, gathering evidence, developing models, and constructing explanations to demonstrate the new knowledge they’ve acquired. The coherent design of the curriculum across lessons, modules, and grade levels helps students use the concepts they’ve learned to build a deep understanding of science and set a firm foundation they’ll build on for years to come.
Cross-curricular connections are a core component within PhD Science. As an example, every module incorporates authentic texts and fine art to build knowledge and create additional accessible entry points to the topic of study.
Three-dimensional teaching and learning are at the heart of the curriculum. As students uncover Disciplinary Core Ideas by engaging in Science and Engineering Practices and applying the lens of Cross-Cutting Concepts, they move from reading about science to doing science.
