What causes lightning?

 

Correct Answer:

Static electricity builds up in the clouds or on the ground as air moves across EarthÍs surface.  When it becomes great enough, it discharges from cloud to ground or ground to cloud.

(Answers will vary.)  

A flash of lightning is a form of static electricity. Great masses of air bump into each other during thunderstorms. As they rub against each other they become electrically charged. Lightning happens when two objects of different charges get close to each other.

Juan and his cooperative group were rotating through eight static electricity centers. At one center they were given a plastic rod, a glass rod, a piece of fur, and a ping pong ball. The students were asked to rub each of the rod ten times with the fur and then place it near the ping pong ball without touching it. To JuanÍs amazement, placing the plastic rod near the ping pong caused it to move across the table, whereas, the metal rod did nothing.

 

Which of the following statements best explains the reaction of the ping pong ball?

a.  The plastic rod made it easier to move the surrounding air.

b.  The metal rod was too dense for it to be electrically charged.

c.  The plastic rod became electrically charged when rubbed with the piece of fur and repelled the ping pong ball.

d.  The metal rod was heavier than the plastic rod and so a heavier type of material was needed to rub it.

Charging Cheerios

 

Activity Description:

Students will build and test a homemade electroscope.

 

Prior to Assessment:

Students need to know that electric charge can be positive or negative and that electric charge can move. Like charges repel and unlike charges attract. When the parts of an electroscope (cheerios in this case) move apart, they are charged. You cannot tell whether the charge is negative or positive. When they move together, the charge has been removed. If they move even further apart, the charge has been increased.

 

Materials:

Science Log Sheet (see below)

For each group of 2 to 3 students:

                                                                        Inside bag #2

wire clothes hanger                              Cotton

thread                                                  Wool

ruler                                                     Silk

scissors                                               Polyester

two Cheerios                                       Fur

comb (plastic, any size)                       Balloon

 

Time Needed:

Allow 20 to 30 minutes for this activity.

Procedure:

1. Begin by asking the students the following: "How could we measure static electricity?" (Amount of repulsion or attraction) "What happens when you walk across the carpet in your stocking feet?" (When you touch a doorknob you feel a shock.)

2. Form cooperative groups and have each group construct an electroscope.

3. Bend the hanger to build a stand as shown below.

4. Measure 12 inches of thread and cut. Tie the thread to two Cheerios, placing one Cheerio on each end of the thread. Tie the thread to the stand so that the Cheerios hang beside each other, but do not touch the table. Run the comb through your hair and bring it near the Cheerios.

5. On the Science Log page, record whether or not the Cheerios repel each other or attract each other.

6. Take the bag that has a variety of fabrics that are labeled out. Rub the comb with each of the fabrics in bag #2 and record on the Science Log page whether of not the Cheerios repel each other or attract each other when one is touched with the comb.

7. Turn in the log page.

8. Put all the science equipment back in the bags as you found them.

Title:  How Likely Is It?

 

Activity Description:

Part I - Students will investigate which type of paper is attracted to a statically charged PVC pipe. They will make predictions, record results, and explain their findings by writing a conclusion.

 

Part II - Students will then plan their own investigation changing another variable other than using different types of paper.

 

Time Needed: 

45 - 60 minutes for each part

 

Procedure:

Part I

1.  Group students into cooperative groups of 4-5 students per group.

 

2.  Explain to students that they will be investigating how different types of paper react to a 12î piece of statically charged PVC pipe. To charge the PVC pipe students will rub the pipe 10 times with a piece of wool.

 

3.  Each group of students will be given six small cups each containing different types of paper which has been previously been punched with a paper hole punch. Types of paper could include:  wax paper, construction paper, tissue paper, paper towel, Xerox paper, newspaper, etc.

 

4.  Before giving each group a PVC pipe and a piece of wool, have students predict which paper will be most attracted to the charged PVC pipe. Have students justify their answers.

 

5.  Pass out (1) PVC pipe and a piece of wool to each group. Have students test each type of paper and record their results on an appropriate chart.

 

6.  To test each piece of paper, students need to charge the PVC pipe by rubbing it 10 times with a piece of wool and holding it slightly above a small pile of paper. The paper will seemingly ïjumpÍ and stick to the charged PVC pipe.

 

7.  Students will need to design an appropriate chart to record the number of pieces of paper that seem to ïstickÍ to the PVC pipe.

 

8.  Students will analyze their findings a write a conclusion based on their data. This conclusion will be shared and discussed with the class to determine how various materials react differently to statically charged PVC pipe.

 

Scoring Guide:

´  Student is able to clearly justify their prediction, accurately records the data collected from the investigation, and write a logical conclusion based on their data  ........... 50 pts.

 

´  Student makes a prediction but the justification is very basic, records data in an appropriate form, and writes a conclusion but doesnÍt use data to support it ......... 40 pts.

 

´  Student makes a prediction with no justification, records data with assistance, and makes an attempt to write a conclusion but has contradicting data  ....................... 30 pts.

 

Part II

1.     Cooperative groups will use their experience in Part I to design a simple experiment changing another variable. Further investigations could include: 

 

´ Using the same type of paper but changing different types of fabric to charge

the PVC pipe.

 

            ´ Using the same type of paper and fabric but using different type of rods (glass,

            rubber, wood, metal).

 

            ´ Using the same type of rod and fabric but using different types of materials

(aluminum foil, pieces of balloon, Styrofoam¬, acetate, puffed rice).

 

            ´ Using the same type of rod, material, and fabric but changing the number of

times you rub the rod with the fabric.

 

2.  Students will need to formulate a simple research question.

 

3.  Design a way to collect data in an organized way.

 

4.  Understand that science investigations use a variety of methods.

 

Scoring Guide:

´  Student is able to formulate a simple but clear research question testing one variable, shows a logical design in their experiment, collects data in an organized way, and shows a complete understanding to their approach to the stated question   ...ƒ........... 50 pts.

 

´  Student is able to formulate a simple research question testing one variable, shows a reasonable design in their experiment, collects data in an appropriate manner, and shows some understanding to their approach to the stated question   ........................... 40 pts.

 

´  Student is able to formulate a simple research question however has an error in the number of variables being used, makes an attempt to design their experiment but needs assistance, collects data but isnÍt logical, and shows limit understanding to their approach to the stated question........................................................................................... 30 pts.
