GRADES 3-5: CHEMISTRY AND PHYSICS
PART ONE: CANDY
Wednesday, January 27, 2010
Students will investigate several different types of sugar and create their own rock candy. Students will observe different types of crystals and make crystal solutions. Students will also learn how many colors are used in candy and see these colors using diffusion and chromatography techniques.

PART TWO: WATER
Wednesday, February 24, 2010
Students will explore the chemistry of water. Students will investigate the rate of chemical reactions by varying the temperature of one key ingredient - water. Students will observe the interaction of water with different materials and
investigate a property of water called surface tension. Students will conduct water races and observe the movement of water on a slope.

PART THREE: LIGHT
Wednesday, March 31, 2010 SOLD OUT!
Students will investigate light and color like never before. Students will explore colored shadows, filters, and light made using chemicals. Students will learn which materials can absorb or transmit light and experiment with ultra-violet light.
Students will learn how fireflies create their light and how to see like a bee.

PART FOUR: SOUND
Wednesday, April 28, 2010
Students will learn how sound travel in waves and see a model of compression and transverse waves. Students will observe sounds made by several objects and compare sounds to develop sound discrimination. Students will create a sound
code and communicate with others using this code. Students will learn about pitch, frequency and amplitude and see if the right combination can really shatter a crystal glass.

PART FIVE: TOYS
Wednesday, May 26, 2010
Students will learn about friction, and potential and kinetic energy as they experiment with roller coasters. Students will build their own roller coasters and change their designs to increase the speed of their coaster. Students will explore
rotational motion and create their very own spinning tops.

PA ASSESSMENT ANCHORS
S4.A.2.1.1 Generate questions about objects, organisms, or events that can be answered through scientific investigations.
S4.C.2.1.1 Identify energy forms, energy transfer, and energy examples (e.g., light, heat, electrical).
S4.C.2.1.2 Describe the flow of energy through an object or system (e.g., feeling radiant heat from a light bulb, eating food to get energy, using a battery to light a bulb or run a fan).
S4.C.3.1.1 Describe changes in motion caused by forces (e.g., magnetic, pushes or pulls, gravity, friction).
S4.C.1.1.1 Use physical properties [e.g., mass, shape, size, volume, color, texture, magnetism, state (i.e., solid, liquid, and gas), conductivity (i.e., electrical and heat)] to describe matter.
S4.A.3.2 Use models to illustrate simple concepts and compare the models to what they represent.
