Level: First Grade
Subject: Science
Integrated Lesson Unit on Properties of Matter
I. Objectives
1. Students should be able to define the three forms of matter such as solid, liquid and gas
2. Students should be able to identify materials that are solid, liquid and gas.
3. Students should be able to differentiate the states of matter based on their shape, weight and visibility.
4. Students should be able to follow instructions and answer questions related to the activities.
5. Students should be able to group materials into their like states whether solid, liquid or gas.
II. Materials
Books, boxes, pencils, balls, papers, pebbles, water, plastic bottles, circular bowls, cups, balloons, plastic bags, needles.
III. Procedure
A. Vocabulary.
Write the words- solid, liquid and gas on the board and introduce what these terms are to the class based on the shape they take. Draw an object beside each term to show the class an example of each.
Solid – box
Liquid – water
Gas – wind
B. Activity and Discussion.
Divide the class into three groups. Give each group some solid objects to examine – boxes, pencils, balls, papers and pebbles. Ask them to describe the shape of the objects. Ask them also to describe the weight of the objects and if they can be seen at all.
Now give each group a glass of water, plastic bottle, circular bowl and a cup. Tell them to pour water on the different containers. Ask them what happens to the shape of the water and how it changes as they poured the water into the different containers. Let the students determine the weight of the water too. Next, let them pour a small amount of water on the table. Ask them what happens to the shape of the water.
Lastly, give the students some balloons, plastic bags and needles. Let them blow the balloons and tie them. Then ask them to prick the balloons with a needle while feeling the air coming out of the holes on the balloons. After that, tell them to fill their plastic bags with air by swinging them in the air and once they get rounded and filled, let them tie the openings. Then again, let them prick the plastic bags with the needle. Let them feel the air coming out of the holes. Now ask the students if gases such air in the balloons and plastic bags have shapes. Ask them too if air has weight, if it is light or heavy.
C. Evaluation.
On the chalkboard, classify the 3 phases of matter and discuss their properties based on the class activity. Ask the students what they have found out about the weight and shapes of solid, liquid and gas. Using the guide questions let the students answer and describe each phase by filling in the blanks to complete the sentences under each phase.
Guide questions:
1. Does solid/liquid/gas have weight? Are they heavy or light?
2. What about the shape of these matters, does solid/liquid/gas have shapes?
3. Does solid have shape? For liquid and gas, do they take the shape of their containers?
4. Are solid/liquid/gas present everywhere? Can we see them with our eyes?

Shape ___ has/have _________ ______has/have _________ ______has/have _____
___has/have________ _____take/takes _________ ______take/takes_____
Visibility ___is/are ________ _____is/are _________ _____is/are_______
D. Conclusion.
Ask the students the examples of solids, liquid and gas used in the activity. Have the students read the sentences that describe the properties of each phase of matter.
IV. Homework
In their science notebook, let the students give 3 examples each of solid, liquid and gas and let them describe the examples based on their properties.
