physical lesson plan lesson plan is it magic or static electricity name shannon wood grade level grade 5 can be adapted for younger subject science date april 20 2010 georgia performance standards gps s5p3 students will investigate the electricity magnetism and their relationship a investigate static electricity enduring understandings like charges repel and unlike charges attract relevance this lesson will introduce students to the concept of static electricity and allow them to observe scientific phenomena make predictions and draw conclusions these are important skills for the students to practice as they utilize the scientific method later prerequisites students should be able to follow directions and work independently students should be familiar with classroom procedures for working in centers students should be able to record predictions results of observations and summarize the concept with help in a journal goals the goal of this lesson if for students to have the opportunity to engage in a hands-on learning experience where they are able to visit two separate science centers and perform scientific experiments with static electricity objectives students will perform two separate experiments in order to observe record and draw conclusions about how static electricity attracts or repels objects one experiment will be to see how static electricity can bend water and the other will be too see how static electricity causes a balloon to attract various objects be able to communicate scientific observations using a journal show general understanding of static electricity and why it caused the phenomena observed in the two experiments materials/equipment · plastic combs · running water

· packing peanuts · salt/pepper flakes · science journals or clipboards with paper · 3 balloons to be blown up by teacher only for safety diagram for board essential vocabulary static charge static electricity friction repel procedures before lesson prepare two centers for the students to perform the experiments set up the water bending experiment near a sink or fountain place nylon combs near the water source paper towels will be needed for clean-up for the balloon experiment place 3 balloons on a table with salt/pepper flakes and several packing grouped together with each balloon students will visit the centers and perform the experiments in groups of three teach this lesson with the assistance of another individual such as a paraprofessional or parent volunteer introduction to begin the lesson teacher will announce to students that the lesson will be about static electricity and determine prior knowledge by calling on students and asking them what they know about the subject the teacher will then put a hat on his/her head and turn it around in circles teacher will then pull hat up slowly and show students how static electricity causes his/her hair to stand up the teacher will explain to the students that the reason the hair stands up is that each strand of hair wants to get away from each other the teacher will ask the students to recall the way magnets repel each other or try to move away from each other.

the teacher will then explain that atoms which are tiny objects that you cannot see are inside hair and on the hat the tiny objects have even smaller objects inside them that contain plus or minus charges the teacher will draw a diagram on the board these tiny objects with the charges are called neutrons and they contain an equal number of plus charges and minus charges by rubbing the hat on my head some of the minus charges jumped off my hair onto the hat when this happened i had all plus charges on my hair and objects with the same charges repel or move away from each other static electricity occurs when the charges jump off one object onto another object like the way they jumped from my hair to the hat development the teacher will explain what he/she wants each student to do in preparation for and during their visit to the science center students will write down in their science journal what they predict will happen at each center before leaving their desk three students will be at each center the group at the water will take turns the group with the balloons will go at the same time when all group members are ready the students will switch to the next center or return to their desks when all members have been to both centers they will all return to their desks together the students will then record their observations and explain in their own words their understanding of static electricity in the two experiments after explaining procedures but before allowing students to begin with the activities the teacher will write on the whiteboard how the predictions and observations page should look in the science journal students will be placed in groups of six one group of six will go to the two centers while the remaining students will wait at their desks the teacher will have the remaining students open up their textbooks to the section on static electricity the teacher will ask the students who are waiting for their turn at the centers to define the essential vocabulary and read along in the book application at the water center students will comb through their hair 10 times and then hold the comb about ½ inch away from a thin stream of water students will observe how the water bends toward the comb at the balloon center students will rub balloons against their clothing or hair and hold them over the pellets the salt and pepper flakes students will observe how the objects are attracted to the balloon students will return to their desks and record their observations students will use their textbook or a handout to draw conclusions and explain their observations using scientific terminology students will compare predictions to observations students will then define vocabulary while other students are

working at the centers if they have time if not the first group of students will be given extra time for the seatwork later closure the teacher will ask students to share predictions and observations the teacher will again review how the charges jumped from different objects which caused the charges to be unbalanced this in turn caused the objects to attract each other or repel each other teacher will ask students which objects were repelled and which were attracted to help students with their summaries or conclusions for those who need support assessment as the students are performing the experiments and writing observations the teacher or an assistant will supervise from a distance allowing students to work independently unless a problem occurs students will receive a lab grade based on following directions and the quality of their journaling journals must contain vocabulary definitions predictions observations and summaries for each center differentiation if students have trouble working independently without direct teacher supervision or with groups without supervision then the teacher may take them over and watch while they are at the centers the teacher may need to assist some students with their journaling if a student is unable to perform the experiment the teacher may perform it for the student to observe reflection i have not taught this lesson although i have performed the comb experiment and the water really bends toward the comb i would expect that the students would have a difficult time understanding the specifics of the science behind the experiments but i believe that using the terminology during the lesson is beneficial i believe the students will enjoy the hands-on aspects of the lesson reference science made simple inc 1995-2009 static electricity learn about static charge static shock retrieved april 22 from http www.sciencemadesimple.com/static.html
