In order to participate in tomorrows laboratory activity, you needed energy. Where did your energy come from? What types of energy conversions took place that allowed you to complete the laboratory activity?

Each wavelength of light has energy, if those wavelengths are in the visible spectrum then you will be able to see. Obviously, seeing is very important in completing the lab activity. This can be represented mathematically by the equation: E=hv, where E is energy, h is Planck's constant (6.63 x 10^-34 joule second) and v is the frequency of the light.

Food you ingest also gives you energy. Cells break down the food into simple sugars through a process called aerobic (requiring oxygen) cellular respiration. This provides energy for the cells and in turn your body. This can be shown as a chemical reaction: glucose (a simple sugar) + oxygen > carbon dioxide + water + energy (in the form of ATP). This can also written as a chemical formula: C6H12O6 + 6O2 > 6CO2 + 6H2O + energy (ATP)

To summarize the energy you need to complete the lab activity comes from:

1. Light-allowing you to see

2. Food-providng energy through cellular respiration

The energy conversions that take place are:

1. Energy of the light to wavelengths you can see

2. Food into sugars into energy

Hope this helps!
