- Students will demonstrate working cooperatively in groups by sharing materials
Materials
– bar magnets
– paper clips
Procedures
- Introduction-
Draw upon and reflect on previous knowledge of magnets from previous lessons and from previous centers they have just visited. Introduce opposites and like sides and how they relate to magnets.
This center will focus on looking at the invisible force field that magnets have around them. You can feel the force when you hold a steel object close to a magnet and try to pull it away. The force becomes weaker when you hold the object further away.
- Development-
Have the students divide into two groups, one group will work on attraction and repelling activity, the other group will work on the magnet strength activity. Have the groups switch once they are each complete.
In the small group, demonstrate how magnets pull together. Have the students pass around magnets so they can feel and understand the pull for themselves.
- Practice-
Have the students make predictions as a group before they start the activity.
Demonstrate how each activity is done before they begin.
As a group, their will be a demonstration of putting two magnets a little bit apart underneath a white piece of paper. Then add iron filings on top so the students can observe how the magnets will pull together, and the iron filings will show the force field. this experiment makes the invisible force field become visible to the students.
- Independent Practice-
Students will complete each activity and fill in the sections of their worksheet that correspond to the activity
Students will also write and reflect something new they learned in their magnet journals
Students will be able to try putting the iron filings on the paper to observe the force field for themselves.
They will then fill out the corresponding worksheet, and write what they have learned in their magnet journals.
- Checking for understanding-
Have a group discussion based on their results and predictions of each activity. Check the students work sheets to see that they have filled out all the information. Check to see each student has written in their magnet journals
- Closure-
Discuss as a group what new things they learned about magnets before they move on to the next center.
Discuss as a group what new things they have learned about magnets, both at this magnet center and from previous lessons
Evaluation-
Check each students worksheets for accuracy, and check the students journals to see their progress and to check to see that they have a grasp on the concepts.
Check each students work sheets to see that they are completed and are accurate and check their journals to see that they are reflecting on what they have learned, and that they understand the concepts.
Reflection-
As a teacher I needed to control the noise level and disturbances from students better. Some of the magnets broke from a result of students not using the magnets appropriately, next time I should monitor the students and make sure they know how to use the magnets appropriately so this does not happen. Also when I first ran this station I did not explain the activities before separating them into groups which caused confusion, I fixed this for the next group. Overall the station ran smoothly and the students seemed to enjoy both activities.
This center was more group focused, and all the students were together cooperatively and participated in discussion.
Overall, the students seemed to enjoy this magnet center, and seemed to take away the main concepts..

In this section the basic idea of motion is explored. This section characterizes motions in to four basic types: translational, circular, projectile, and rotational. Also, a key point is to understand motion diagrams and be able to make them. These diagrams are the beginning foundation understanding motion. The graph is a display of the displacement of an object at constant time interval. Then in section two we transfer the motion diagram to a particle model. These are exactly the same graphs, but the object is now represented in a simpler form of a particle. In the third section we translate the particle diagram to a position versus time graph. On the x-axis we have displacement of the car in meters or another SI Unit. In the y-axis we have time which is show in seconds. In section four we then transfer the position-time graph to a velocity-time graph. To form the velocity time graph you determine the slope of the line in the position-time graph. This is done by (R2-R1)/(T2-T1)= velocity (meters/seconds).

Begin the class period with a discussion of what the students think periodic motion is. After a few minutes, bring out a pendulum from behind the lab table and use it as an example of periodic motion. Point out its various parts – bob, length, pivot point. Demonstrate what is meant by period and amplitude. Spend a few minutes discussing the accuracy of measuring a single period. The students should realize that timing how long it takes for ten cycles and dividing by 10 will lessen the effects of reaction time and result in a more accurate measurement of the period. Break up the class into groups. Each group is given a pendulum with a different bob but all pendulums are 1 meter in length. (A different option would be to have the students construct their own pendulums 1 meter in length. If doing so,make sure to discuss that the length of the pendulum is measured from the pivot
point to the center of gravity of the pendulum bob.) Each group is to find the period of their pendulum by timing it for 10 cycles and using an amplitude of 10 cm. After doing so, they are to experiment with other amplitudes (5 cm, 15 cm, 20 cm, etc.) to determine if the amplitude effects the period. All groups record their data in the class data table on the board under the following headings: Color of bob, Time for 10 cycles, Period, Effect of changing the amplitude. When all groups have recorded their data, call the class together for a discussion of the results. It should be apparent that the shape and mass of the bob and the amplitude have no effect on the period. Small differences can be explained by experimental error. If the students are not sure that the rings are actually different masses, bring out a scale and prove it. If you are using infant stacking rings, there will be about a 50% difference between the largest and smallest ring’s mass. Each group is given a different length of string to create a new pendulum. Lengths should vary from 25 cm to 2 m. As before the groups will find the period of their pendulum. This time they will graph their results on a length versus period graph. While the students are finding the period of their pendulums, hang a piece of end roll paper about 21/2 meters long on a wall and label the axes. The vertical axis is marked off to the actual length of the pendulum. The horizontal axis is the period marked in a convenient scale. When the students have found the period of their pendulum they should remove it from its support bar and hang it on the graph at its corresponding period. Remind the students that the actual length of the pendulum is measured from the pivot to the center of gravity of the bob. When using rings for bobs, the center of gravity is at the center of the ring, therefore it is important that the centers of the rings be lined up on the horizontal axis. By using this self graphing technique, it is not necessary for the students to measure the pendulum’s length and the effect of the length of the pendulum on the period is shown quite dramatically. Once all groups have added their pendulums to the graph discuss the results. The graph should look like a y-parabola. If it is not obvious that it is a parabola remember that the origin is a point on the graph – zero length will havezero period. With a marker sketch the curve on the graph. Discuss with the students the shape of the graph and what it represents mathematically. Hopefully they will come up with the idea that there is a direct relationship between the length and the square of the period. (This depends on their level of math ability.) If this relationship is not obvious, lead the students by a discussion of what needs to be done to straighten out the graph. This approach usually gets to the idea of squaring the period. The students should now verify these predictions by squaring their period and regraphing on the second end roll graph. The students should transfer their pendulums from the first to the second graph. The resulting graph should be a straight line through the origin. At this point the class can discuss the results that the square of the period is directly proportional to the length of the pendulum. This would be a good point to start a discussion of the equation and theory of a pendulum.
Conclusion:
This activity will take more than the usual lab period. A good breaking point would be after finding the effect of the bob and the amplitude. This activity can be used with elementary students up to the first graph.
Evaluation:
The student’s understanding of this material can be evaluated by having them use the graph to predict what the period of a pendulum will be for a specific length. They can then experimentally verify their prediction.

Test this. 6. Try and locate magnets in your house. Do these magnet show the same qualities as the ones above? DON’T FORGET TO BRING YOUR MAGNETS BACK TO CLASS!!! |
Practice: | “A Magnetic Discussion” 1. List the following on the overhead for students to answer while you check their homework. MAGNETIC OR NOT (Don’t list answers, just items) REFRIGERATOR DOOR **YES**Students are familiar with this. SOFA **NO** Students may argue a sleeper sofa has metal, but most textiles, wood, and foam insulation are not magnetic. COKE CAN (OR 7UP) **YES**These are made of steel. PEPSI CAN **NO** These are made of aluminum. DOLLAR BILL **YES**The ink has a little bit of iron in it, so that pop and candy machines can tell if its the real thing and not a photocopy. CEREAL **NO** HOWEVER, cereals claim to be iron fortified, and in some cereals, if a magnet is dropped into the box, it can be recovered from the bottom of the box with iron filings stuck to it. Iron fortified?? 2. Go over the above list and include in your discussion student observations of things that were magnetic in their home. Give as many students as possible a chance to answer.

Subject: Physics
Teacher Name:
Topic: | Metric System Conversions |
Content: | Learning how to convert metric measurements within the Metric System Vocabulary: conversion, units, meter, gram, liter, metric system of measurement, standards, deci, deca, milli, hecto, kilo, centi |
Goals: | For students to be able to convert metric measurements within the Metric System |
Objectives: | Students will be able to convert metric measurements within the Metric System. Students will be able to use the “stairstep” and convert metric units by using the metric prefixes correctly. Students will be able to move the decimal to its correct position in coverting metric measurements. |
Materials: | Chalkboard, textbook, class notes, calculator, help sheets, pencil, and paper |
Introduction: | Students will be reminded of the purpose of a universal measuring system. Teacher will also review material previously taught as part of this unit of study: importance of standards in measurement and the numerical values of prefixes used within the metric system |
Development: | Teacher will lecture as well as demonstrate on the board the mathematical significance of decimals holding place value. The teacher will demonstrate the proper use of the “stairsteps” in determining conversion values. |
Practice: | Students will be given two days of actual guided practice. Those days will consist of a practical application lab where they are measuring objects, determining English equivalents of meter, centimeter, gram, etc., and this day of solving problems with teacher/peer assistance. |
Accommodations: | Students with IEPs will be allowed to use the “stairstep” sheet during all problem-solving, i.e. guided practice, homework, quiz, and test.
