Advance Preparation:
  1. Prepare “Mystery Bags” by placing a variety of 8–10 magnetic and non-magnetic objects, such as paper clips, aluminum foil,staples, chalk, crayons, markers, pens,highlighters, scissors, thumb tacks, fishingweights, copper wire, nickels, pennies, pencils, lead, steel nails,wood, pieces of soap, cork, brass brads, or steel brads, in a brown, paper lunch bag (1 per group).
  2. Prepare the phase models. Three Petri dishes will be required to create the physical models of the solid, liquid, and gaseous states of matter. After filling the Petri dishes with the BBs, use hot glue to affix the lids to the base to prevent spillage. (1 set per teacher)
  3. Solid- Fill the first Petri dish with BBspacked closely together to impair movement.
  4. Liquid- Fill the second Petri dish with about half the number of BBs that were used in the first Petri dish.
  5. Gas- Fill the third Petri dish with about a dozen BBs.
  6. For the Properties of Matter- States of Matter you will need to have 30 hole punch dots for every student.
  7. For the Explore/Explain – Properties of Matter – Relative Density/Mass, you will need to gather objects for measuring mass. You will need to collect enough for each group to have one set.Examples of these objects include the following: paper clips, pencils, pens, crayons, markers, pennies, washers, pebbles, blocks of wood, and plastic items.
  8. For the Explore/Explain – Properties of Matter – Solubility in Water, you will need Teacher Resource: Dissolving Station Cards. Please note there are instructions for two different stations on each card. Page 1 has instructions for Station 1 and Station 2, and page 2 has instructions for Stations 3 and 4. The teacher resource should be copied on cardstock or other sturdy paper and cut apart. The station cards will be placed at the appropriate station for the investigation.
  9. Gather the objects that will be used in the Explore/Explain: Properties of Matter - Electrical Conductors and Insulators. The insulated wire may need to have ½–1 inch of the insulation stripped from each end. The light bulbs needed for this phase are miniature and should be 3.8-V or Christmas lights cut apart with leads.
  10. Prepare attachment(s) as necessary.

Background Information:

This lesson bundles SEs that address physical properties of matter in order to set a foundation for understanding and classifying chemical and physical changes.

During this unit, students will classify matter according to their physical properties. Additionally, students will focus on the physical properties of mixtures and solutions.Throughout the year,many process skills will be embedded to support scientific methods and measurement.

  • Teacher Resource: PowerPoint: Physical Properties
Science Notebooks:
Instruct students to list the properties listed in the Power Point that they will learn about.
EXPLORE/EXPLAIN–Properties of Matter - Magnetism / SuggestedDays 1 (continued) and 2
  1. The teacher will conduct a demonstration to introduce the concept of magnetism.
  2. Tie a paper clip to one end of a 70 cm long kite string or sewing thread. Tape the other end of the string on a stable surface, such as a desk. Allow the paper clip to rest on top of the table.
  3. Pick up the paper clip, and lay it on your palm, extending your palm the length of the string.
  1. Place the magnet about 1 cm away from the paper clip. As soon as the magnetic attraction is felt, release the paper clip from the palm of your hand.
  1. As the paper clip begins to float, move the magnet up, down, and side to side so that the paper clip follows it.
  1. Instruct students to carefully place a piece of paper in between the paper clip and the magnet so they can see if the paper clip is still floating inthe air.
Ask:
  • Can you think of another object that might exhibit the same properties as the paper clip and magnet? Answers may vary, but students should suggest metals.
  • What are the characteristics of magnetism?Answers may vary, but could include: a magnetic force surrounds the magnet, Magnets have two poles, North-seeking and South-seeking. There is a force of attraction between unlike poles or repulsion between like poles.
  • How do you know when an object interacts with a magnet? The object will be attracted (pulled) toward the magnet.
  1. Instruct students to draw the floating magnet set-up and record observations and reflections in their notebook. Instruct students to record and answer the question: What does the property of magnetism show about matter?
  1. Divide the class into groups of 4 or 5 students. Give each group a Mystery Bag.
  1. Instruct students to create a data table in their notebook, or distribute the Optional Handout: Magnetic Attraction.
  1. Provide students the directions for the Mystery Bag activity:
  • Remove and list items in the Mystery Bag.
  • Predict whether the item is attracted or not attracted to a magnet.
  • Test each item with a magnet.
  • Place an X or a √ in the proper column, and answer the questions at the bottom of the page.

EXPLAIN–Magnetism / SuggestedDay 2 (continued)
  1. Facilitate a discussion with the students focused on the concept “properties of matter”. Use the following questions to guide the discussion.
  • What is a property?A property describes how an object looks, feels, or behaves. A property is any characteristic which can be used to describe or identify a substance.
  • How do properties help us identify substances? Properties are unique to matter.
  • What can you learn about objects by classifying them? You can learn the identity of objects, common characteristics of similar objects, etc.
  • What does the property of magnetism show about matter?It shows whether or not the matter is composed of or contains iron-based metal, such as iron, nickel, or cobalt..
  1. Guide class through a whole group discussion as students share data from their Handout: Magnetic Attraction or from their notebooks.
  2. What type of material seemed to be attracted to a magnet?Items with iron or steel seem to be attracted to a magnet.Were all the metals attracted to magnets? No
  3. Why do you think only some metals were attracted to a magnet? Allow students to explain their findings from the activity.
  4. Explain that each magnet has a north-seeking pole and a south-seekingpole. Show students a magnet with a labeled north and south pole.
  5. Continue the discussion:
  • What else has a north and south pole?Students should respond that the Earth has a north and south pole. Guide students in their thinking to help them draw the conclusion that the Earth is also a magnet.
  • Opposite poles of magnets (north and south) are attracted to each other. The opposite occurs, repelling, when the same poles (north and north or south and south) come near each other.
  1. Partner students with their nearest neighbors, distribute magnets (2 per group), and direct them to model the magnets attracting and repelling.
Students should be able to answer the following question:
  • How did the magnets react when opposite poles and like poles were placed near each other?Students should respond that they felt the magnets pulling towards each other when opposite poles attracted and the magnets pushed away from each other when like poles repelled.
  1. Explain the pulling force that was felt during the activity with the two magnets:
  • The pulling you felt when opposite poles were near each other is called “attract”, and the pushing you felt when like poles were near each other is called “repel”. Direct students to accurately draw and label magnets attracting and repelling on the Handout Attract and Repel or use the Handout as a guide for what to draw in their science notebooks.
  1. Use a projector to show the class the following activity.
  • Place a magnet (use both a bar and a horseshoe magnet) underneath a sheet of white paper. Gently sprinkle iron filings on top of the magnets. The iron filings will show the lines of force for each of the magnets’ magnetic field.
  • Where do the lines of force appear to be the strongest?Students should respond that the lines of force are more concentrated around the poles of the magnets.
  1. Provide an explanation to reinforce the concept of magnetism:
  • As we discussed earlier, the Earth also has a North and South Pole. If we were able to sprinkle iron filings on the Earth, we would see the same lines of force that you saw with the smaller magnets.
  1. Allow time for the students to accurately draw and label the lines of force they saw with the iron filings on the Handout: Attract and Repel, or use the Handout as a guide for what to draw in their science notebooks.
  2. Facilitate a discussion on the ways that attraction and repulsion are seen and used as a part of their lives. Assist the discussion as necessary to ensure that the following points are brought up:
  • The Earth’s magnetic field protects the Earth from dangerous radiation from the Sun.
  • A compass points north because the iron needle is attracted to the magnetic north pole.
  • Magnets are useful in sorting and separating some materials.
  • Some high speed trains work because of magnetic repulsion.

Instructional Notes:
This discussion is an important foundational piece for the understanding of physical properties and how they help us classify matter.
Students may know that some of the common objects are metals, but they may not know the specific metal(s) that compose each sample. Students do not have to know this material:
  • Current pennies are zinc coins coated in copper.
  • U.S. nickels are 25% nickeland 75% copper.
  • Nails, staples, and thumbtacks are typically composed of steel.
  • Paper clips are generally made from galvanized steel. Steel is an alloy whose main ingredient is iron. Students may not be familiar with the term alloy. An alloy is a mixture of metals.
  • Fishing weights may be composed of coated lead or a zinc alloy although brass, tungsten, and steel are replacing these in many areas.
  • Copper wire and aluminum foil both are named from the elements from which they are made.
