o Students will construct a 2-d model depicting spring and neap tides during a lunar cycle.
o Students will differentiate between spring and neap tides.
o Students will relate the position of the moon and sun to ocean tides.
o Students will explain how the relative position of the moon and sun and the gravitational pull by each causes spring and neap tides.
o Students will explain the cause of tidal range differences during spring and neap tides as it relates to the gravitational pull exerted by the moon and sun.
o Students will identify moon phases as related to ocean tides.
o Students will explore the daily and monthly semidiurnal and mixed tidal patterns and how those patterns relate to the rotation of the earth on its axis and its revolution around the sun.
o Print 1 set of “task cards” per group of 2 or 3 on colored paper.
o Print 1 set of diagram labels and picture cards per group on white paper.
o Print 1 diagram board per group
o Laminate (optional)
o Cut and bag cards/board pieces.
This is a great formative assessment activity once you have given students the basic information about the causes of ocean tides. It is perfect for taking a lecture on ocean tides to a higher cognitive level and solidifying the concepts for students. This such as hard content for students to grasp and this activity is designed to help students truly understand and explain the causes of ocean tides. I have provided instructions to play it as a game but you can use it however you see fit… notes page, whole class discussion, interactive notebooking activity, etc. BE CREATIVE with how you differentiate it to fit your classes needs. Note: This activity does not get into the reason for mixed, diurnal and semidiurnal tidal patterns. I wrote this activity for middle school and that is a bit beyond what I think a middle school student would need to know about ocean tides.
