# Counting on Bridges (K)

**Standards of Learning: 2009 Math (K.1, K.2, K.10, K.12); 2010 Science (K.1, K.4)**

Explore the engineering involved in bridges through the fable The Three Billy Goats Gruff. Students will work in pairs to engineer their own bridge and test the strength of their bridge under various weights. Students will compare objects based on relative size and weight and record their observations. Your classroom of engineers will have fun using math and science in this hands-on lesson.

# Light and Shadow (K)

**Standards of Learning: 2010 Science (K.8)**

After reading Nothing Sticks Like a Shadow, students will explore shadows by creating their own hand shadow puppet using a flashlight and screen. Students will explore how reflected light, like that of the moon, can also be used to create shadows. Students will hold a mirror to reflect light onto their screens and experiment with different objects to block the light.

# The Shape of Things (K)

**Standards of Learning: 2009 Math (K.11, K.12, K.13); 2010 Science (K-1)**

Recognizing and describing the properties of two-dimensional shapes are important skills for all students as well as critical to their understanding of geometry. Through engaging, hands-on activities, students will identify, sort, and graph basic shapes as well as learn to recognize those shapes in the world around them.

# All Aboard the Number Train (1st grade)

**Standards of Learning: Grade 1 Math (1.5, 1.6, 1.9, 1.18)**

All Aboard for this mathematical problem solving adventure! Students will collaborate with a partner as they determine the value of Cuisenaire rods based on their length. They will then use these manipulatives to compare numbers and add sums. Finally, they will use mathematical clues to create a train using the correct Cuisenaire rods.

# Engineering with Curious George (1st grade)

**Standards of Learning: 2009 Math (1.18); 2010 Science (1.1d)**

After listening to a Curious George adventure story, students will investigate how wind exerts force on an object and how the wind can be harnessed to move objects. Given various materials, students will design wind catchers to power a vehicle. They will also test their wind catcher designs by measuring the distance their vehicle traveled and reevaluate how they might engineer a better design.

# Give Me a Clue! (1st grade)

**Standards of Learning: 2009 Math (1.14, 1.15, 1.17)**

Recognition and description of patterns will help students be detectives! Students will take their own fingerprints and examine them to identify patterns. They will analyze this data through collecting, sorting, and graphing. Students will then use their new detective skills to solve a mystery!

# Build a "Great" Wall (2nd Grade)

**Standards of Learning: 2009 Math (2.11, 2.6); 2008 Social Studies (2.1)**

Make a model of one of the greatest engineering feats of the ancient world...The Great Wall of China. Students will explore metric units of length, as they construct a classroom model of the Great Wall. Students will discuss characteristics of walls and how the materials used to build them affect a wall's construction, stability, and strength.

# Matter Heats Up (2nd grade)

**Standards of Learning: 2009 Math (2.14); 2010 Science (2.1, 2.3)**

Students will observe and measure changes in matter that occur as a result of changes in temperature. They will explore the use of their senses in scientific investigation by describing the properties of various objects. Through the use of heat sensitive paper and heat energy detection devices, students will investigate the movement of heat from one object to another.

# Strike One (2nd grade)

**Standards of Learning: 2009 Math (2.18; 3.18)**

In this lesson, students will investigate probability as chance through games and hands-on activities. Students will work collaboratively to identify the likelihood of an event occurring using the terms: impossible, unlikely, equally likely, likely, and certain. Students will identify the possible outcomes of situations and predict results using probability expressed as a fraction.
