Matter and Energy Lab Report Introduction

For this lab activity, you will observe two scenarios - The Iced Tea Debate and Salty Soup -

and record your observations of physical and chemical change. During your observations, you

will determine how each scenario represents the laws of conservation of matter and energy.

Problem:

How can matter and energy be described and conserved in a variety of systems?

Hypotheses:

As you view each scenario, make a prediction about what will occur when prompted by the

video.

The Iced Tea Debate

The Salty Soup

Predictions-What do you

think will happen?

My hypothesis is that the tea will My hypothesis is that some of the

have a physical change and water evaporates but the salt does

have frozen completely. not. Thus, causing there to be a
