Name of Activity Grab Bag Magnetism Investigation
Author David Stack and Jessica Swenson
Keywords Magnetism, non-lego, science, hypothesis
Subject Non-LEGO
Grade Level 5
Time 1 Hour Total
Brief Description Students investigate whether a material is magnetic or non-magnetic to learn the properties of magnetism.
Lesson Objectives: Understand similar properties that make something magnetic.
Materials Needed: One magnet and grab bag per group. Grab bag includes: penny, washer, nut, rubber square, clothes pin, paper clip, and battery.
Preparation and Set Up: Collect about eight objects that are magnetic or non-magnetic and put them in a bag for each group.
Procedure Give the students the grab bag of materials. Have them hypothesize (introduce this word) if each object will be magnetic or non-magnetic and record this on their investigation sheet. Have the class discuss whether they think each object is magnetic or non-magnetic and record this on the board. Give each group a magnet and have them test and record for each object. Have the class discuss the results.

Author STOMP
Keywords electricity, magnetism, final, project, non-lego
Subject Non-LEGO
Grade Level 4
Time 2 Hours Total
Brief Description Students will have two weeks to design and build something to help a superhero rescue all of the paper clips in the city of Boston from an evil supervillain hiding in a cave.
Lesson Objectives: -Incorporate both electricity and magnetism in a final project.
-Encourage students to design while thinking about a client and what he/she will need to accomplish.
Encourage students to be creative and reaffirm that there is no one correct answer.
Materials Needed: For the first week, some materials should be replied. You may then allow students to request certain materials (within reason) if they feel it would help their design for the next and final week.

First Week Materials:
-Batteries
-Wire
-Lightbulbs (both LED and standard small lightbulbs)
-Playdough
-Nails
-Paperclips, for testing
-Assorted materials such as paper, felt, tape, popsicle sticks, etc.

Preparation and Set Up: -Collect supplies.
-Prepare a model of the supervillain in its cave (can be accomplished by a bunch of paperclips within a dark box)
-May consider bringing large pieces of paper in for students to draw their designs.
-Divide students into groups of 2-3.
Necessary Background Students should now have an excellent background on both electricity and magnetism. They should realize that a combination of electricity and magnetism will be needed to successfully complete this activity.
Procedure
  1. Divide students into groups of 2 or 3.
  2. Describe to them the problem that they will have to solve: a supervillain has taken over all of the paperclips in Boston and is now hiding out in a cave! If you were to design someone to help the superhero save the city, what would you design?
  3. Distribute large pieces of paper and encourage students to brainstorm for quite a while. Think about what problems they need to solve and how they will design for a specific person.
  4. Allow students to build a little with the provided materials in week 1 and request materials for week 2.
  5. In week 2, have students complete their designs and demonstrate to the class if they have time.

Introduction to Magnetism

ACTIVITY HEADER

 

 

 

Name of Activity Introduction to Magnetism
Author STOMP
Keywords magnetism, electricity, circuits
Subject Non-LEGO
Grade Level 4
Time 1 Hour Total
Brief Description Students will be introduced to the concept of magnetism through a combination of discussion, video, and a short activity.
Lesson Objectives: -Introduce students to the concept of magnetism.
-Ensure students understand how electricity and magnetism are linked.
-Discuss the difference between naturally magnetic materials and electromagnets. Which is more useful to us and why? (Answer: electromagnets are used more often than natural magnets because they are able to be turned on and off.)
-A demonstration can be done using magnets and compasses, to be found in the CEEO. Students can see how the magnetic field of the magnet will influence the compass, which relies on the magnetic field of the Earth to show direction.
Materials Needed: -Compasses
-Magnets
Preparation and Set Up: -Collect enough materials such that students can test their compasses and magnets in pairs.
Necessary Background Students should be given an introduction on magnetism, what it is, how we use it, how it is related to electricity, etc. We found that Bill Nye has a couple of excellent videos on Youtube explaining magnetism and electromagnetism.
Procedure
  1. Provide students with background.
  2. Use BIll Nye or other videos to aid in the lesson portion of this activity (optional).
  3. Allow students to test out the compasses and magnets.
  4. Have students feel the magnets attract and repel when certain poles are facing eachother.

Electromagnets

Name of Activity Electromagnets
Author STOMP
Keywords electricity, magnetism, electromagnets, circuits, magnet
Subject Non-LEGO
Grade Level 4
Time 1 Hour Total
Brief Description Students will be asked to create their own electromagnet, illustrating to them the relationship between electricity and magnetism.
Lesson Objectives: Allow students to use their prior knowledge of electricity and magnetism to create an electromagnet.
Materials Needed: -Nails with iron core, preferably. (Note: Stainless steel nails will probably not work!)
-Wire
-D or 9V batteries
-Electrical tape
-Small paper clips (for testing magnetism)
Preparation and Set Up: -Collect materials
-Cut and strip several feet of electrical wire (~4-5 feet per group)
Necessary Background Students should now have a good understanding of both electricity and magnetism. They should have had an introduction explaining how the two concepts are related.
Procedure
  1. Arrange students into pairs or small groups. If materials are not an issue, pairs would probably be best.
  2. Provide each pair with one D or 9V battery, one strand of wire, one or more nails, and a bit of electrical tape.
  3. Allow students to try to create the electromagnet on their own, although it will be necessary to explain to them why wrapping the wire around the nail will create a magnetic field.
  4. Students will probably struggle, but most of the times the problem is just that they need to wrap more wire around the nail to create a stronger magnetic field.

Electricity and Magnetism Challenge

Name of Activity Electricity and Magnetism Challenge
Author STOMP
Keywords electricity, magnetism
Subject Non-LEGO
Grade Level 4, 5, 6, 7
Time 1 Hour Total
Brief Description (Final Project) Students must complete 3 electricity and magnetism-related challenges to earn their STOMP diplomas
Lesson Objectives: -Give students a series of tasks in which they must work together and use the knowledge gained throughout the STOMP semester to illustrate what they have learned
Materials Needed: -Challenge Papers (attached)
-diploma (optional – reward for completing all challenges)
for individual challenges…
-Static Electricity: balloon, paper
-Circuits: Playdoh, LEDs, 9V battery
-Magnetism: Playdoh
Preparation and Set Up: -Put students in groups (if not already done)
-Print out a copy of each challenge for each group, and fold up the challenges so they cannot be seen
-Place all materials on table for kids to access
Necessary Background None
Procedure 1. Hand out a copy of the first challenge to each group, and countdown to when the challenge can be opened 2. Students complete challenges and come to STOMPer when finished. ┬áIf done correctly, group moves onto next challenge 3. When all challenges are completed, kids get their diploma (Note: some groups will finish before others, so its a good idea to have a “bonus challenge” in mind – we had kids build a circuit that has both parallel and series components when they were finished)
