Physical Science : Standard 4 - Forces In Nature
Checks for Understanding 4.1 | 4.2 | 4.3 | 4.4
Science Curriculum Standards 3202 - Physical Science	Internet Resources
Demonstrate the effect of gravity on objects. 4.1	Your Weight on Other Worlds - This Exploratorium site gets your students' attention by showing that their weight will vary with different gravitational attraction (you will not believe what you would weigh on a Neutron star!). Then, a very good presentation of the difference between weight and mass is given. A weight and mass converter is provided by ConvertMe.com. After your students use this converter, perhaps you could discuss if it is appropriate to perform this type of conversion. Mass vs Weight - discussion of the difference and interactive questions to check for understanding
Explore the difference between mass and weight. 4.2	Your Weight on Other Worlds - This Exploratorium site gets your students' attention by showing that their weight will vary with different gravitational attraction (you will not believe what you would weigh on a Neutron star!). Then, a very good presentation of the difference between weight and mass is given. A weight and mass converter is provided by ConvertMe.com. After your students use this converter, perhaps you could discuss if it is appropriate to perform this type of conversion. Science Terms: Distinctions, Restrictions, and Confusions - Bartelby.com points out that an absolute conversion factor between these two units is not technically sound Mass vs Weight - discussion of the difference and interactive questions to check for understanding
Design, demonstrate, and explain simple and compound machines. 4.3
Gather and analyze data and solve problems related to mechanical advantage and efficiency of simple machines. 4.4	Definition and Mathematics of Work Calculating the Amount of Work Done by Forces - This tutorial includes a large number of practice questions to check understanding. Power - a tutorial with practice questions An index of Work and Energy animations from the Physics Classroom Pulley - Investigate mechanical advantage of a pulley with this interactive java applet Pulley System - (raise or lower the load with the mouse) If you click on the mouse button, a spring balance will appear showing the tension in the string. Inclined Plane - This Java applet demonstrates a motion on an inclined plane with constant velocity and the corresponding forces.
State Performance Indicators 4.1 | 4.2 | 4.3 | 4.4 | 4.5
Distinguish between mass and weight using SI units. SPI 4.1	British and Metric Conversions - a series of pages relating to converting to or from metric units Finding the Mass of an Object - tutorial on using a triple-beam balance which includes questions to answer Mass vs Weight - discussion of the difference and interactive questions to check for understanding Platform Scales Addition - weigh several items and find the sum in hundredths of a gram or Platform Scales Subtraction - weigh several items and find the difference in hundredths of a gram or A weight and mass converter is provided by ConvertMe.com. After your students use this converter, perhaps you could discuss if it is appropriate to perform this type of conversion. Your Weight on Other Worlds - This Exploratorium site gets your students' attention by showing that their weight will vary with different gravitational attraction (you will not believe what you would weigh on a Neutron star!). Then, a very good presentation of the difference between weight and mass is given. Using a Platform Scale - practice using scales like the one in a doctor's office, five Gregs will drop on the scale, waiting to be weighed, see how quickly you can weigh them or
Identify the effects of gravitational force on a falling body or satellite. SPI 4.2	The Law of Action-Reaction (Revisited) Mass, Force and Acceleration - Watch as you fill out the chart to see how mass, force, and acceleration are related. When you are done, see if you can write a rule. Momentum - "mass in motion" Momentum and Impulse Connection - this tutorial includes a large number of practice questions to check understanding Motion, Forces, and Newton's Laws - includes a good drawing of a graph Motion with Constant Acceleration - This Java applet shows a car moving with constant acceleration Objects falling to Earth from a variety of locations
Identify various types of simple machines. SPI 4.3	Compound Machine - answer a series of questions which require the selection of the most appropriate simple machine Design and Test - This project simulates the Design and Test process through the development of a virtual paint ball catapult. The student must build catapults capable of performing a variety of tasks, stay within the allotted budget, and interpret test results to fine tune their design. Lever - attach a new mass piece or put it to another place with pressed mouse button Levers: 1st, 2nd, and 3rd class levers - transparency master Eureka: The Lever - a YouTube video Machines Make Life Easier - a set of activities about simple machines Move Our Principal - learn about the six simple machines then use their knowledge to assist their principal. Pulley Systems - high quality transparency master Rube Goldberg Machines - a simple machines PowerPoint show by Matt Aufman and Steve Case, University of Mississippi [23 slides] Simple Machines game from Harcourt School Simple Machines - An excellent overview from the Franklin Institute On-Line Simple Machines Activities: Learn about simple and compound machines while you explore the House and Tool Shed at E-Heads! Simple Machines Made Simple - an introduction to the six simple machines Simple Machines Make Things Go - this 57 page booklet includes lesson plans and worksheets - Caution: UK spelling is used Simple Machines - a 21 slide show posted by Mike McKee of UCF The Six Simple Machines - a 26 slide show with good examples and illustrations [Caution: the movie file is not included thus slide 26 does not work] Sunken Millions - a Simple Machines review game Work and Simple Machines - a 47 slide show with practice questions
Recognize the simple machines found in a compound machine. SPI 4.4	Compound Machine - answer a series of questions which require the selection of the most appropriate simple machine
Solve application problems related to mechanical advantage and the efficiency of simple machines, given appropriate equations (MA=FO/FI and Eff=WO/WI). SPI 4.5	Inclined Plane - This Java applet demonstrates a motion on an inclined plane with constant velocity and the corresponding forces. Inclined Plane and Friction - interactive applet that could be used to collect force information or Machines Make Life Easier - a set of activities about simple machines Move Our Principal - learn about the six simple machines then use their knowledge to assist their principal. Pulley - Investigate mechanical advantage of a pulley with this interactive java applet Pulley System - (raise or lower the load with the mouse) If you click on the mouse button, a spring balance will appear showing the tension in the string. Simple Machines Made Simple - interactive lesson about the six simple machines and how the machines make work easier Simple Machines Make Things Go - this 57 page booklet includes lesson plans and worksheets - Caution: UK spelling is used
