# Built to Measure (3rd grade)

**Standards of Learning: 2009 Math (3.9); 2010 Science (3.1)**

Engineers are the problem-solving force of our world today; they integrate math, science, and technology to make our lives more safe and comfortable. Engineers design to meet our needs and wants. In this lesson, students apply their understanding of metric measurement as they build simple models to solve a problem.

# GeoSnow: Exploring the World of Snowflakes (3rd grade)

**Standards of Learning: 2009 Math (2.15, 3.14, 4.12a); 2010 Science (3.9, 4.6)**

A snowflake, or snow crystal, forms in the clouds when water vapor cools and forms an ice crystal. Students will learn about snowflake formation by exploring the geometric concepts of symmetry as well as 2-dimensional and 3-dimensional structures. Students will discover what every snowflake has in common as well as what makes each snowflake unique.

# Learning with Levers (3rd grade)

**Standards of Learning: 2010 Science (3.1, 3.2); 2016 Math (3.15)**

How do levers work? In this lesson students will create a lever and explore the mechanical advantage of using a lever to lift an object. Students will collect and analyze data to determine the best placement of the fulcrum to accomplish a task.

# Electric Circuits 2.0 (4th grade)

**Standards of Learning: 2010 Science (4.1, 4.3)**

Using SWITCH-ON© pieces, students will discover how to make an open/closed circuit, a series circuit, and a parallel circuit. Students will examine and test various items to investigate properties of conductors and insulators. LED, and photo cell explorations will allow for extra observations and predictions.

# Say "Ahh"-gebra (4th grade)

**Standards of Learning: 2009 Math (4.21, 4.5, 4.6)**

Algebraic thinking: Are you having a difficult time explaining algebraic concepts to your students? In this lesson, students will create their own set of simple math manipulatives to help them better understand basic algebraic concepts such as using variables to create and solve equations.

# Solar Connections (4th grade)

**Standards of Learning: 2009 Math (4.4, 4.7); 2010 Science (4.1, 4.2, 4.9c)**

Solar energy—no longer fuel for the future—it's fuel for now. Solar panels are popping up everywhere—on houses and factories, roadside signs, cars, and even toys—using energy from the sun to generate electrical energy. Take a closer look at solar energy collection, practice math strategies for multiplication and computation, then use solar toys to conduct experiments to collect data for graphing.

# Light: What's Your Angle - NEW! (5th grade)

**Standards of Learning: 2009 Science (5.3 b, c); 2009 Math (5.11)**

Ever wonder how you could see around a corner undetected or how a submarine sees above the water? This lesson will bend your students thinking and shed light on reflection and angles. Using mirrors, lasers, and protractors students will create, investigate, and measure angles. Their discoveries will be used to demonstrate and generalize the law of reflection.

# Looking at Sound (5th grade)

**Standards of Learning: 2009 Math (5.1, 5.2, 5.20); 2010 Science (5.2)**

Take a closer look at sound. Review key concepts of the physics of sound such as amplitude, frenquency, and pitch, and experiment using new technology. Using Audacity® software, we will track sounds produced by pitch pipes to better understand sound waves and use Go!® Motion sensors to graph the motion of movements (echolocation) and create a decimal number line. After this lesson, students will have a new way of looking at sound.

# Move Over Aunt Sally (5th grade)

**Standards of Learning: 2009 Math (5.4, 5.7)**

Order of Operations is the focus of this lesson! Since the 1660s, mathematicians have agreed on an order of operations to follow when solving problems. Your students will explore the mathematical reasoning that supports solving equations in a particular order and experience firsthand what happens when the order of operations is not honored. Students will use the Order of Operations acronym PEMDAS to help them value and understand the steps that need to be followed in problem solving.
