Lesson Stage 1, 2
Key Vocabulary
Sun, Moon, The Milky Way, comet, asteroid, Saturn, Mars, Mercury, Earth, Venus, Uranus, Jupiter, Neptune, Pluto
Materials
Scale, markers or colored pencils, graph paper, 5-10 common household objects of different weights, baseball, marshmallows.
Sunshine State Standard
Represent and Interpret Data.5.MD.2. Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Use operations on fractions for this grade to solve problems involving information presented in line plots
Instructional Objectives
Math Content Objective: The students will be able to weigh common objects on a scale, convert the earthly weight of the object to that of it were on the moon, and chart the results on a line or bar graph.
Language Objective: The students will participate in an oral discussion at the end of the activity on the results of their date from the charts.
Hook /Anticipatory Set
Pass around a baseball and marshmallow. Ask the students, “how do you think we can get this baseball to weigh the same as this marshmallow?” Answers- water or gravity make objects lighter, but today we are going to focus on gravity, especially between the Earth and the moon.
Procedures
Focus Lesson: The teacher will discuss and give information on gravity.
- Gravity is a force that attracts all physical objects towards each other
-The Earth's moon is the only heavenly body that people have walked on. -The gravity of the moon is 17% of Earth's gravity.
-To calculate your weight on the Moon, multiply your weight by 0.17.
The teacher will demonstrate how to weigh one of the objects, record it on the char, and the multiply the earthly weight by 0.17 to find the weight of the object if it were on the moon and then record that result on the table and then putting them into a bar/line graph. Recording of the results on the chart can be done in a variety of ways, 1. Two separate bar/line graphs (one labeled Earth weight & one moon weight) 2. A double bar/line graph, etc…
Guided Practice: After the teacher has done the first example, the teacher and students will do one together. As the students are working one the problem in pairs, the teacher will walk around the classroom and answer questions and help students on a partner bases. The teacher will also ask questions openly about gravity and if time allows the teacher will have students come to the board and work the problems to demonstrate their understanding of multiplication of percents and charting results on the table and graphs.
Collaborative Practice: The students the will work in their groups to complete the table and graphs (though they are in groups students must have their own personal copy of the work). While the students are working together, the teacher will move around the classroom and answer any questions. During this time, the teacher will also ask the class general questions about surface area to ensure that every on understands.
Independent Practice: The students must complete the homework; see real life connection section for further assignment.
Type of assessment
Completed Line/Bar Graphs
Grading system
7-10 = Excellent 4-6 = Satisfactory 3 or less = Needs Improvement
Closure
Discussion on results from charts. Did any object surprise you? Was there one object you expected to weigh more and ended up weighing less? Do you see a pattern? Etc…
Real life connection
Find two more objects at home and convert their weights. Add the new objects to the chart to share the next day.
