Engage:
The teacher will present the class with a fish tank full of water, and will begin to tilt it back and forth to make waves inside the tank. Students will be asked what is causing waves to form inside the tank? After the teacher has listened and responded to each student’s answer, the teacher will then ask multiple questions for class discussion before the lesson, such as what makes water tides? What is gravity? Does the moon or the sun affect the changing tides? What are the different types of tides? What are some things that change or creates tides?
Explore: Students will watch the NASA clip “What is a Tide?” Students will see how both the Sun and moon’s gravitational force creates low and high tides. Students will discover from the video, that it takes 12 hours and 15 minutes for the tides to change in the United States. Students will be asked to answer and find out, why this happens in this time frame and where tides change in the U.S.? Students will find that this rise in tides is due to the earth’s rotation and that high tide occurs when the sun or moon’s gravitational pull is greatest or closest to the earth. Students will find where there are usually two changes of tides throughout the day on the western and eastern borders of the United States. They will also find that …show more content…
A post-lesson quiz of how and why tides are created, will be issued. The post-lesson quiz will consist of a 20 questions, 10 multiple choice and 10 short answer. Students will be assessed on what they have learned and what they understood from their correct answers on the quiz, but also how they’ve expressed their understanding during the group work during the lesson. Students may also show their understanding by verbally answering questions to the teacher if
