Activity 1 ø Solids and Liquids

TEKS ADDRESSED:

112.5. Science, Grade 3.

3.2(B) Scientific processes. The student uses scientific inquiry methods during field and laboratory investigations. The student is expected to collect information by observing and measuring.

3.7(B) Science concepts. The student knows that matter has physical properties. The student is expected to identify matter as liquids, solids, and gases.

CONCEPT STATEMENT:

The universe is made up of all types of matter. In order for students to comprehend the different characteristics, attributes, and qualities of matter, students should to be introduced to the topic by first investigating a variety of solids and liquids.
The scientific process is fundamental to many aspects of the science curriculum. Students should be introduce to and experience the investigative aspect of the scientific process by observing, sorting, categorizing, comparing and recording different characteristics of liquid and solid objects.
This lesson provides a foundation for students to build upon during further studies of matter and the scientific process.

PERFORMANCE OBJECTIVES:

á Students will be able to explain the different characteristics / properties of solids and liquids.

á Students will use properties of solids and liquids to classify objects

á Students will work cooperatively in groups investigating, discussing and sorting a variety of objects according to their observable characteristics

á Students will use data sheets to record and annotate observations and findings.

RESOURCES:

For the teacher

4 sentence strips with the following statements

Ideally they should each have an illustration representing the statement.

o Hold their shape and do not turn into a puddle

o Take their shape of their container

o Stay flat on top unless moving

o DonÕt hold their shape, and do not make a puddle

2 large Solids and Liquids signs for the class display

For the class

Materials listed are for a class of 32 students - adjust quantities depending on actual class size.

1 plastic spoon
2 index cards (3x5) labeled #1 and #2
1 rock, any kind, big enough for the whole class to see
1 cotton ball
1 piece of fabric at least a few inches square
3 transparent containers of different shaper (one with a lid)
1 cafeteria tray
8-12 sentence strips
Push pins or masking tape
1 wide-tip felt marker
A space about 6-9 ft. wide on a bulletin board or wall for a display

The display needs to be at a height students can reach. It also needs to be stay up for the entire Matter unit in order for it to be used during other lessons.

For each student

1 binder, clipboard, or folder to keep journal pages together
1 copy of Solids student data sheet from Matter Gems¨ Guide
1 copy of Liquids student data sheet from Matter Gems¨ Guide

Materials to make solid/liquid collections

8 clear plastic bags to hold collections of solid and liquid items

Clear gallon-size freezer bags with double interlocking seals are ideal.

32 clear plastic vials with tight-fitting lids
8 or more small glass beads or marbles
1 bag of cotton balls
8 or more small rocks or pebbles
1 box of wooden toothpicks, any kind
1 small box of metal paperclips
8 screws, nuts, bolts, washers and/or coins
8 small pieces of fabric
1 cup of a thick, clear liquid like corn syrup or dishwashing detergent
1 cup of a thick, opaque liquid like shampoo, hair conditioner, or hand lotion
1 oz. of red food coloring
1 oz. of blue food coloring
1 bottle of water
(optional) a small container of glue to seal lids on containers, if needed

Note: You may want to substitute other items for the solids and liquids listed. Each item should be made of just one material so it can be classified as either a solid or a liquid. Select liquids that will not spoil so they can be stored and used again with future classes. If vials to hold the liquids are not available, other clear containers that will not leak or break, such as small plastic water bottles, will work.

SAFETY CONSIDERATIONS:

Students may become overly excited and curious and have a tendency to get a bit rambunctious and careless when expose to so many objects at once. In order to prevent havoc, they should be instructed to gently handle the materials at their table and NOT to throw any of the items around.
Students will also be manipulating certain types of liquids that contain chemicals. These particular items could cause discomfort and/or injury if ingested or rubbed into the eyes. Students should be told not to puncture or open the containers containing liquids. If this occurs, they are to contact the teacher and wash their hands immediately.
As an added precaution, have all students wash their hands at the conclusion of the lesson.
