** __The Study of Plants__ ** ** By Caitlin **
 * __ Botany __**
 * ** Scientists who study plants are called //botanists.// **
 * ** There are more than 350,000 different types of plants on Earth. **
 * ** The basic study of botany includes: **
 * ** understanding the root system **
 * ** why the roots are important **
 * ** botanical terms: **
 * ** parts of a plant **
 * ** parts of a flower **
 * ** parts of a leaf **
 * ** different types of flowers **
 * ** seeds **

__**How does botany relate to physical science?**__
 * ** plants use photosynthesis to translate light energy into chemical energy **
 * ** light energy is absorbed from the Sun and produced into sugar the plant needs to survive **
 * ** chlorophyll (pigment in green plants that absorbs solar energy) assists in photosynthesis as well **
 * ** chlorophyll also gives the plant its green color **

**__Lights Out Lab__** __** Materials **__
 * ** house plant **
 * ** black construction paper **
 * ** scissors **
 * ** tape **



** __Question__: What will happen to a leaf it its deprived of sunlight? **

** __Hypothesis__: The coloration of the leaf will go from green to pale and it will have a brittle texture. **

**__Procedures__:** **A)** **B)**  **C)**
 * 1) ** Cover one leaf with black construction paper by taping two pieces of construction paper togethor with the leaf in between. **
 * 2) ** Once a day for two to three weeks, uncover the leaf and make observations of its //__complexion__// and //__texture__//. **
 * 3) ** Record all observations. **

** __NOTE__: Be sure that when observing the leaf, you move away from any natural sources of light and are quick and concise with **** your observations. **
