Static Electricity Essential Lab #6

Mary Tweedy, Curriculum Support Specialist ScienceKeisha Kidd, Curriculum Support Specialist ScienceDr. Millard Lightburn, Instructional Supervisor

Department of Mathematics and ScienceThis power point was developed for use with the Grade 5 Quarter 2 Essential Lab # 6. Preview the teacher copy and get necessary preparation for the lab done. Benchmarks are also part of the teacher edition.1What Do You Know About Atoms?All matter is made up of tiny particles called atoms.Atoms contain protons, electrons and neutrons.Protons have a positive charge, electrons a negative charge, and neutrons a neutral charge.

Department of Mathematics and ScienceEngage: Click on What Do You Know About Atoms? (from Scholastic Study Jams) to review content on atoms.2Atoms

Lets Model the Parts of an Atom

Need: 8 Volunteers (2 neutrons, 2 electrons, 2 protons, 1 nucleus, and 1 atom) Heres what to do: Atom person holds up the sign and stands near the outside of the circles. The Nucleus stands inside the circle and hold his/her sign upThe 2 Protons go inside the center of the circle. The 2 Neutrons go inside the circleOne Electron stands on each of the outer circlesBoth Electrons walk quickly around their orbit

All: Draw a diagram of the model we just made in your journal.

Department of Mathematics and ScienceEngage continued. See Essential Lab #6 Static Electricity Teachers version p. 15.3All matter is made up of tiny particles called atoms. What are an atoms 3 basic parts?NeutronsProtonsElectronsWhat are their electrical charges?NeutralPositiveNegative

Discovery Video: Static Electricity

Department of Mathematics and ScienceEngage/explore: The first site is open to all - http://www.teachersdomain.org/asset/phy03_vid_zsnap/Ask students the question. Discuss their ideas. Then play the video and compare their ideas to the facts.If you have Discovery access, you can play the second video.

Now its Your Turn to Explore

Essential Lab #6 Static ElectricityKey Question: How does static electricity cause objects to attract or repel?

Rotate through the 4 stations, follow the directions, and record your data in the chart.Department of Mathematics and ScienceExplore: See Essential Lab #6 Static Electricity teacher page for directions.

Key Question: How does static electricity cause objects to attract or repel?

Explain/Evaluatea. How does what you observed at Station 1 provide evidence to answer your key question?

b. How does what you observed at Station 2 provide evidence to answer your key question?

c. How does what you observed at Station 3 provide evidence to answer your key question?

d. How does what you observed at Station 4 provide evidence to answer your key question? Department of Mathematics and ScienceExplain/Evaluate: See Essential Lab #6 Static Electricity teacher page for directions.

7 Lets Take Another LookThe protons positive charges and their electrons negative charges are typically electrically balanced in an atom.

Rubbing the balloon on ones hair (friction) causes it to gain electrons and become negatively charged. This makes your hair stand on end by giving them all the same charge, making them repel one another.

Department of Mathematics and ScienceExplain: Demo and discuss activity explanation.8

Try This: Discovery Exploration: Static Electricity

Rubbing the balloon on your hair, gives it a surplus of electrons. A wall will have an opposite charge, causing them to attract one another and allowing the balloon to stick to the wall.

Department of Mathematics and ScienceExplain continuedExtension: If you have Discovery, you can click on the link: Static Electricity9What Do You Know Now?What is static electricity?When does a static charge build up on an object?What happens when a static charge builds up on an object?What is an example from nature of static electricity?

Department of Mathematics and ScienceEvaluate: Students can answer these questions and make illustrations with their explanations in their journals.10What is Static Electricity?Static electricity is a buildup of electrical charge in an object.Friction can cause a static charge buildup.Static charge causes objects to attract or repel.Static charge can be released as a brief burst of electrical energy, sometimes visible as a spark, and felt as a shock.

When Does a Static Charge Build Up on an Object?

There are forces that can change an objects electrical charge. One such force is friction. Friction is produced by rubbing two objects together. For example, when you walk across the floor, your shoes rub against the carpet. This creates friction. The friction causes electrons to flow from the carpet to your body. Both your body and the carpet become electrically charged.

Department of Mathematics and ScienceExplain/Evaluate: students can share their explanation.

12What causes static electricity?http://www.ehow.com/video_4756347_what-causes-static-electricity.htmlDepartment of Mathematics and ScienceExplain/Elaborate: Click on the link to an explanation of what causes static electricity (high level). Students need to be familiar with conductors, insulators, electricity, neutralize, and electric field.13

What Happens When a Static Charge Builds Up on an Object?

An electrically charged object can exert a force on other objects. A charged object will pull on uncharged objects and on objects that have an opposite charge. A charged object will push away another charged object that has the same charge. Static charge can also jump from a charged object to another object. The shock you might feel after rubbing your feet on the carpet is an example of this jump of electrical charge.

Department of Mathematics and ScienceExplain/Evaluate: students can share their explanation.

What Is an Example from Nature?

Lightning is the release of a very large static charge. Friction causes static electricity to build up in the clouds. Sometimes, electrons jump from cloud to cloud, releasing a very large static charge. The sky lights up, and we see a flash of lightning. Sometimes electrons jump from the cloud to the ground. This creates another flash of lightning.
