Investigating variation
Investigating Variation
Variation means differences among living things of the same species.For example, all humans are the same species, but we don’t all look the same — we have different heights, hair colors, and eye colors.
Investigation of Variation
To investigate variation, scientists or students can collect data and compare characteristics.
Example investigation: Investigating height in your class
Measure the height of all students in the class.
Write the values in a table.
Draw a bar graph or chart.
Observe differences — some are tall, some short, some in between.
Types of Variation
Inherited variation – passed from parents (e.g., eye color, hair type).
Environmental variation – caused by surroundings
Fun Fact :
No two people (except identical twins) have the exact same DNA? That’s why everyone is unique — even your fingerprints are one of a kind!
