# Chia Seeds Lab

## Purpose

To see if the Chia seeds will grow faster in sunlight or in artificial light.

## Hypothesis

If the pots are placed in different lights, then the one placed under the natural sunlight will grow faster, because that’s how nature wants it to grow.

## Variables

Independent Variables
• The type of lighting the plants get.
• One plant will be placed under artificial light and one plant will be placed under natural sunlight.

Dependent Variables

• The height of each plant.

Extraneous Variables

• The weather, meaning the amount of sunlight the control plant will get.

Control variables

• The amount of soil given to each plant.
• The amount of water given to each plant.
• The pot each plant is planted in.

## Lab Setup

Procedure

• Put even amounts of soil in two different petri dishes
• Put three seeds in each petri dish
• Put 10ml of water in each petri dish
• Place one petri dish under the artificial light
• Place one petri dish on the window so natural sunlight hits the plant
• Wait and record results (there were none)

## Why It Didn't Work...

• The environment in which we grew our Chia seeds was too cool. Chia seeds like to be grown in tempters within 70-85° F
• We chose a shallow petri dish in which to grow our Chia seeds, therefore there wasn't not much room for our seeds to grow because their roots couldn't take hold

## If you could do the lab again based on your data what would you do to further knowledge your topic?

• The first thing would be to plant the seeds in a bigger "pot''. Such as a vase.
• The second thing that we would do differently would be to put more seeds in the pot. This would be to have a greater chance of having sprouts.

## Research

How will the window affect the direct sunlight hitting the plants?

• the intensity of the light drops rapidly the further the plant is moved from the window. A simple move of two or three feet away from a window can reduce the light intensity by more than 50 percent.

• North facing windows tend to have the weakest light intensity and are often in relatively deep shade throughout the window. It may be possible to grow shade-loving plants in a north-facing window during the summer months, but in the winter, these windows are usually not conducive to plant growth.

• South facing windows; The sun follows a slightly southern east-to-west arc across the sky, southern windows usually have strong light intensity. Plants placed in unblocked southern windows will typically receive the most light.

• East facing windows benefit from the morning sun, when the rays are not quite as strong. They’re are often good for plants that need moderate sunlight or morning sunlight only.

• West windows get the full afternoon and evening sun, which can be surprisingly strong in the summer. Although they don't get the same intensity of light as southern exposures, a west-facing window is a good place for your sun-loving plants.
