What Lives Beneath Our Oceans?

Think about the different types of fish you know What sizes might they be? How could we organize information about fish?

Collecting Fish Data

Scientists measure fish length in centimeters Data helps us understand fish populations We can use this data to create graphs Today we'll work with real fish length measurements

Building Our Dot Plot

Use the fish length data provided Create a dot plot on the class chart Each dot represents one fish Line up dots above the correct length measurement

Reading Our Dot Plot

Look for clusters - where are most fish lengths? Find gaps - what lengths have no fish? Identify the range - shortest to longest fish What does this tell us about our fish population?

Fish Life Cycles and Sustainability

{"left":"Young fish are usually smaller\nAdult fish grow to different maximum sizes\nOverfishing affects fish populations","right":"We need to protect breeding adults\nSustainable fishing helps ocean ecosystems\nData helps us make good decisions"}

Writing About Our Ocean Data

Write 3-4 sentences describing your dot plot Include: clusters, gaps, and range Use descriptive language about the ocean Share your findings with a partner
