Some are named after the type of term progression, such as a harmonic sequence or a geometric sequence. Some are named after the type of mathematical operators being used, such as a square or cube sequence. Models (e.g., physical, mathematical, computer models) can be used to simulate systems and interactions-including energy, matter, and information flows-within and between systems at different scales.Ī sequence is an ordered list of numbers, in which each number is referred to as a term. Computers are useful for a variety of purposes, such as running simulations to test different ways of solving a problem or to see which one is most efficient or economical and in making a persuasive presentation to a client about how a given design will meet his or her needs. ![]() Use mathematical models and/or computer simulations to predict the effects of a design solution on systems and/or the interactions between systems.Īlignment agreement: Thanks for your feedback!īoth physical models and computers can be used in various ways to aid in the engineering design process. This activity focuses on the following Three Dimensional Learning aspects of NGSS: Use a computer simulation to model the impact of proposed solutions to a complex real-world problem with numerous criteria and constraints on interactions within and between systems relevant to the problem.Ĭlick to view other curriculum aligned to this Performance Expectation Verify terms of sequence using measurement by robot motion.Illustrate Fibonacci sequence using LEGO EV3.This activity builds upon students' innate fascination with robotics, exposing them to the notion of sequences and developing their critical thinking skills.Īfter this activity, students should be able to: Thanks to engineers, robots have migrated from factory shop floors (as industrial manipulators) to outer space (as interplanetary explorers), hospitals (as minimally invasive surgical assistants), homes (as vacuum cleaners and lawn mowers), and battlefields (as unmanned air, underwater, and ground vehicles). The Fibonacci sequence is also the basis for the golden ratio, which is a classical proportion used in architecture and design. The Fibonacci sequence can be seen in nature in the spirals of a sunflower's seeds and the shape of a snail's shell. The Fibonacci sequence is widely used in engineering applications including computer data structures and sorting algorithms, financial engineering, audio compression, and architectural engineering. This engineering curriculum aligns to Next Generation Science Standards ( NGSS). ![]() To program the robot to move according to these numbers, students break down the sequence into simple algebraic equations so that the computer can understand the Fibonacci sequence. By designing a robot that moves based on the Fibonacci sequence of numbers, they can better visualize how quickly the numbers in the sequence grow. Within teams, students are assigned roles: group leader, chassis builder, arm builder, chief programmer, and Fibonacci verifier. ![]() Using the LEGO® EV3 robotics kit, students construct and program robots to illustrate and explore the Fibonacci sequence.
