Gravity

$0.00

Gravity introduces students to the concept of gravitational force. Students will learn how to explain gravity and identify key figures in history who have contributed to the world’s knowledge about how gravity works.

The “Options for Lesson” section provides several suggestions as additional or alternative activities for the lesson. One option is to assign students different aspects about gravity to research and present to the class. You could also conduct an experiment with the students in which you drop different sized objects to test whether or not the gravitational pull of the earth does or does not change.

Description

What our Gravity lesson plan includes

Lesson Objectives and Overview: Gravity teaches students how to define and explain the concept of gravity. Students will discover how the earth’s gravitational force attracts objects toward its center. They will learn that this is how planets remain in orbit around the sun. This lesson is for students in 3rd grade and 4th grade.

Classroom Procedure

Every lesson plan provides you with a classroom procedure page that outlines a step-by-step guide to follow. You do not have to follow the guide exactly. The guide helps you organize the lesson and details when to hand out worksheets. It also lists information in the yellow box that you might find useful. You will find the lesson objectives, state standards, and number of class sessions the lesson should take to complete in this area. In addition, it describes the supplies you will need as well as what and how you need to prepare beforehand. In addition to the handouts, this lesson requires poster paper, colored pencils, glue, and scissors. Students will also need access to the internet.

Options for Lesson

There are many suggestions in the “Options for Lesson” section for additional activities and exercises or alternate ways to approach certain parts of the lesson. One such option is to assign students different aspects of gravity to research and later present to the class. Students could also conduct experiments with dropping objects of different sizes to the ground to test the gravitational pull of the earth on those objects. You could invite an astronomer or other scientist to speak to the class about gravity. Another idea is to discuss how and why satellites and other objects remain floating around in space. Students could research how much their weight would change if they were on other planets. One last idea is to use the gravity equation as a math exercise.

Teacher Notes

The teacher notes page provides an extra paragraph of information or guidance regarding the subject matter of the lesson. It suggests teaching this lesson at the same time as others about aspects of physics or motion. You can use the lines on this page to write any thoughts you have as you prepare.

GRAVITY LESSON PLAN CONTENT PAGES

There are four content pages in this lesson. Students will first learn how to define gravity and related terms. The lesson describes how it works and then talks about significant figures such as Sir Isaac Newton and Albert Einstein. Students will learn how these two scientists impacted the world of science forever with their theories and discoveries.

They will also discover the concept of a black hole. They will learn that black holes have the strongest gravitational pull in the universe. Even light cannot escape.

GRAVITY LESSON PLAN WORKSHEETS

The Gravity lesson plan includes three worksheets: an activity worksheet, a practice worksheet, and a homework assignment. Each one will help solidify students’ grasp of the lesson material and help them demonstrate their knowledge. The guidelines on the classroom procedure page outline when to hand out each worksheet to the class.

WITH OR WITHOUT POSTER ACTIVITY

Depending on what you prefer, students can work by themselves, with a partner, or in a group for the activity. Students will create a poster that shows what the universe would be like both with and without gravity. They will include facts as well as drawings or images from other sources. They can use the two empty boxes on the worksheet to create a rough draft. You can provide students with poster boards for their final draft. You will grade the posters using the rubric at the bottom of the activity worksheet.

TRUE OR FALSE PRACTICE WORKSHEET

The practice worksheet splits into three sections. For the first section, students will read 10 statements and decide whether they are true (T) or false (F). For the second section, they will write the number of each false statement from the first section. Then they will rewrite the statements to make them true. The final section lists five questions for the students to answer.

GRAVITY HOMEWORK ASSIGNMENT

For the homework assignment, students will first fill in the blanks on 10 statements. They will use the words in the word bank only once. Next, they will answer 10 who or what questions as they relate to gravity. For instance, their answer to “What happened in 1846?” should relate to the discovery of the planet Neptune, which proved Newton’s laws correct.

Worksheet Answer Keys

The final two pages of the document are answer keys for the practice and homework worksheets. The correct answers are in red to make it easy to compare them to students’ responses. Given the nature of the questions on both worksheets, students’ responses should mirror those on the answer keys almost exactly. There may be some variation, however, on the questions in the second part of the homework assignment. If you choose to administer the lesson pages to your students via PDF, you will need to save a new file that omits these pages. Otherwise, you can simply print out the applicable pages and keep these as reference for yourself when grading assignments.
