Students are introduced to the concept of a programming language while learning a simple programming language called Logo, which is used for drawing. Basic introduction to fundamental programming concepts of functions, variables and loops. Lesson is designed to concisely teach these concepts, and to promote future exploration through challenges, bonus sections, and time experiment. Goal of the lesson is to get students’ feet wet and lead to a greater interest in learning Logo and to computer programming/Computer Science as a whole.

### Less is more | grades 3-5

- Marley Zelinger

This lesson will use the context of resources to introduce the concept of problem solving with constraints. The concept of limited resources, regarding renewable and nonrenewable, and how to use resources effectively will be explored through a problem solving game in which the students will need to cross the floor with limited materials. The need for actions such as “reduce, reuse, recycle”, as well as what it means to have a limited amount of something, will be discussed and connected to the activity. A worksheet is included in the lesson plan for concept assessment.

### Light Properties | grades 4-5

- Robert Vogel

The goal for the lesson is for students to recognize that light travels in a straight line until it strikes or an object or travels from one medium to another and that light can be reflecting, refracted, and absorbed. Students will do inexpensive and simple activities involving reflection, refraction, and absorption of light to explore these concepts. Students will then discuss results as a group and apply these concepts to phenomenon experienced in their own lives.

### Marshmallow Tower – An Introduction to Civil Engineering | grades 3-5

- Benjamin Schoenleber

This lesson plan is designed to help middle school students understand the concepts of civil engineering and the thought process behind building design. It will also teach them the principles behind the engineering design process and will describe just who engineers are and what they do. The goal of this plan is for students to design and construct the highest and most stable tower possible comprised of only marshmallows and toothpicks.

### Momentum | grades 4-5

- Robert Vogel

Students will be able to observe the conservation of momentum and explain its relation to the masses and velocities of objects in a 1 dimension system. They will reinforce these concepts by conducting a momentum lab themselves. The students will learn why Newton’s cradle, a commonly seen yet often misunderstood object, works and then be able to experiment with momentum themselves.

### Roller Coaster – Ups and Downs of Energy | grades 3-5

- Jared Alosio

Energy cannot be created or destroyed – however, it can be transferred from one form to another. This is the law of conservation of energy; one of the paramount laws which govern our universe. From it, numerous studies in engineering, physics, chemistry, and biology have emerged, as have all Grand Challenges of Engineering. Every Grand Challenge involves studying energy in closed systems, so foundational knowledge about what energy is and how it transfers between forms is important to establish.

### Speed, Distance, and Time Forensics | grade 5

- Mark Chen

Speed, distance, and time form a fundamental relationship that builds the foundation for future scientific and mathematic explorations. This lesson plan allows students to conduct a forensic investigation. After being exposed to the speed equation, students will apply the speed equation to see which of three cars actually was part of a crime scene. Students will use “evidence” such as police speed camera photos and individuals’ “testimony” to determine a car’s speed and infer how far the car has travelled. Students will also graph this motion to demonstrate visually location of each car.

### States, What’s the Matter? | grades 3-5

- Mark Chen

There are three main states of matter that surrounds us: solid, liquid, and gas. Each one of these states has their own unique properties that distinguish it from the others. Students should be able to determine the properties of each state, and how these properties can interact with one another. Specifically, students should predict and observe how energy can be transferred. Students will first be exposed to the molecular configurations of different states of matter. They will draw out how “close” molecules are to one another, and how that distance affects the state of matter. They will also build their own device to record energy transfer.

### To the Skies! | grades 2-4

- Jared Alosio

There are four basic forces that explain the motion of an aircraft during flight – Weight, Lift, Thrust, and Drag. Weight is the downward force on the airplane from gravity. It is made up of the gross weight of the aircraft, the payload, the fuel, and the passengers combined. Lift is the upward force underneath and above the wings, pushing and pulling the plane up off of the ground. Thrust is the forward force in the direction of the airplane’s motion, which is driven by the propeller or the jets, depending on the type of plane. Drag is the backward force which opposes motion of the plane, due to friction between air and the aircraft. Students will learn these forces and how to design an aircraft to accomplish several flight purposes, primarily through building differently shaped paper airplanes. After completing the lesson, students will have a base understanding of aircraft flight and why planes are designed in the way they are.

### Truss building: shapes and structures of popsicle sticks bridges| grades 3-5

- Henry Quach

This lesson will provide an introduction to how force, energy, and motion are related while a load is applied to a bridge. Students will learn and apply the concepts of trusses and forces when designing, building, testing, and evaluating their own popsicle stick bridges. These concepts will converge in relevance to new building materials for applications in infrastructure for the Grand Challenges of Engineering.

### Understanding electricity| grades 3-5

- Savini Prematilleke

This lesson plan highlights one of the 14 Grand Challenges for Engineering in the 21st century identified by the National Academy of Engineering, entitled Enhance Virtual Reality. This challenge is focused on the potential of virtual reality to become a powerful tool in numerous industries. While the core of engineering virtual reality is developing its software, it wouldn’t be possible without the hardware, like most other technology. The objective of this lesson plan is to introduce simple physics concepts to young students in the stimulating context of virtual reality. The primary focus of the lesson is on understanding convex and concave lenses and their integral role in the hardware of virtual reality headsets.
