## Strand Updates:

## Biological Sciences:

The biology students began the last quarter studying plant diversity and reproduction and are now studying animal diversity, anatomy, and physiology. Dissection, microscopy, and experimentation have all been conducted in lab.

## Making Soap! The chemistry students reacted a fat with sodium hydroxide to create mini bars of soap. Recycled crayons were used for a touch of color. | ## Exploring Radioactive DecayThe chemistry students completed a lab activity simulating radioactive decay. They studied the probability of a random process by selecting a decay number and then rolling 6-8-10-12 and 20-sided dice. Working collaboratively, they discovered how the half-life changed as the number of sides on the dice increased. | ## Comparative Anatomy & Physiology Biology students have been dissecting various animal specimens to compare their anatomical structures as they study the anatomy and physiology of various organ systems. Here, Damaris Arias (Lafayette HS) and Jessica Phan (Bethel HS) study a bullfrog. |

## Engineering:

## Junior Year Engineering/Physics

The last quarter engineering project aims to prepare students for the next year collaboration project with the College of William and Mary. We are learning basics of Arduino circuits and coding.

## Spaceship Project In this project, students built something that could have been a spaceship interface in a 1970s science fiction movie. They made a cool control panel with a switch and lights that turn on when you press the switch. You can decide whether the lights mean “Engage Hyperdrive” or “Fire the lasers!”. A green LED will be on, until you press a button. When the Arduino gets a signal from the button, the green light turns off and two other lights start blinking. | ## What the future holds It is all about team work, collaboration, and creativity. Students are charged with the task to come up with the questions that they will study next year. Professor Kidwell and his team introduced Airduino project and students quickly started generating ideas of what sensor-loaded Arduino could bring to their study, so that the meaningful results of this exploration would help our community. Pollution, sea level, and many other projects were suggested by our juniors. | ## Physics Demo Third quarter project was a success! Students came up with demonstrations that were relevant to both, first and second semesters of physics. Picture shows Mara Collier (Gloucester HS) demonstrating Barkhausen effect, series of sudden changes in the size and orientation of ferromagnetic domains, or microscopic clusters of aligned atomic magnets, that occurs during a continuous process of magnetization. The amplifier allowed us to hear these changes. |

## Senior Year Engineering/Physics

## EDIE lab senior computational science and engineering/physics strand students work together to finalize and prototype their projects | ## C++ course students are working on a final project in which they program an ATM machine | ## Quantum Mechanics students are learning quantum mechanics of various physical systems and hydrogen atom with Schrodinger's equation. They learn purely quantum effects such as quantum tunneling and quantum entanglement. |

## Computational Sciences

## Multimeters Using multimeters, students are exploring electric voltage of different objects. | ## Electric Fields Students are mapping electric fields produced by charges. | ## Electric Potential Students are mapping equipotential lines produced by charges. |

## Van de Graaff generator A Van de Graaff generator is an electrostatic generator that uses a moving belt to accumulate electric charge on a hollow metal globe. | ## Before A student is about to experience a dramatic effect. When a student puts a hand on the sphere, the electrons will spread out onto that person as they repel the other electrons. | ## AfterThey are most obvious in a person's hair because the like charges of the electrons repel each other and cause the hairs to stand up and spread away from each other. |

## Before

## NumPy NumPy is a library for the Python programming language, adding support for large, multi-dimensional arrays and matrices, along with a large collection of high-level mathematical functions to operate on these arrays. | ## 3D Arrays Students getting better and better at NumPy. NumPy allows the creation of 3D or N-Dimensional arrays. | ## Matplotlib Matplotlib is a plotting library for the Python programming language and its numerical mathematics extension NumPy. Students use these libraries to produce high-quality plots. |

## Applied Calculus

## Graphing PlanesHow to graph a 3D plane on a 2D paper. Here is the plane x + 2y + z = 4 | ## Domain & Range Using GeoGebra 3D to explore the domain and range of a function z = f(x, y) | ## Extrema Using GeoGebra 3D to visualize the minimums, maximums, and saddle points of 3D graphs. |

## Calculus

## Diverge or Converge? Applying the direct comparison test to prove that the given series converges. | ## Intervals Applying the Ratio Test to identify what values we can plug in for x and have the series converge. | ## Definite Integrals Combining integrals and the Alternating Series Estimation Theorem to calculate the value of the definite integral |
