Language of Science… How we study science today was
developed long ago by our scientist fore-fathers and mothers
Today you start to learn the language of Science!!!

Objective Objective Students will learn how to conduct the scientific method
while studying creation. Students will discover the different plants around their
MCS campus by making observations and mapping their
locations.

Intentional Observations
We will focus on Primarily on the plants as we explore outside
Plant Observations
Where: MCS Courtyard
Date: 9/6/13
Time: 11:15 AM
Plant 1 1. The leaves are long and slender.
2. The leaves are pale/light green.
3. The leaf texture is smooth and waxy.

ExampleExample For example, suppose you want to figure
out the fastest route to walk home from school.
You will try several different routes and time how long it takes you to get home by each one.
Since you are only interested in finding a route that is fastest for you, you will do the walking yourself.

DataData DataData are pieces of information
that come from the experiment May be quantitative
Ex: numbers – amount, frequency, measurements
or qualitative descriptive: color, taste, smell,
texture, shape, and sound

Data CollectionData Collection Data must be organized into:
Tables
Charts
Graphs

Data Analysis Data analysis involves:
ComparingComparing the data collected from the experimental group and control group
ReflectionReflection did the data support your original hypothesis? Did it NOT support your hypothesis?
Sometimes analysis requires additional observations!

ConclusionConclusion A conclusion is a
statement/answer to the hypothesis based on the data obtained from the experiment

RetestRetest
In order to verify the results, experiments must be retested.
