For high and average achievers, click to these websites:

In the Spi-Spy-Exploring the World of science site, the pupils need to manually choose a topic from the lists. They need to select the heading Materials and choose Absorbency, Ceramic and later on Metals.

Homework for the pupils

Recording Sheet used in the experiments

gee HZ — Sun, 16 Nov 2008 23:32:29 +0000

Instructions:

1. Appoint one of your friends to be a recording person (the one who write the findings)

2. All member of the group are required to participate and work together during the experiment session. No one should be left out.

3. Whenever the moving or swapping from station 1 to 2, or 2 to 3 et cetera to take place, each and every group are required to clean up and arrange all the objects that have been used in a proper means for other groups to use.

4. Each experiment should not take more than 5 minutes to carry out.

Materials used:

Station 1: cotton threads; metal wires; weights and retort stands

Station 2: A metal ruler and a plastic ruler.

Station 3: A plastic ruler and wooden sticks.

Station 4: Ping pong ball, match sticks, erasers, beakers, and a bottle of water.

Station 5: salt, sugar, sand, beakers, a bottle of water and spatulas.

Station	What do you suppose to do?	What do you notice?	What do you think?
1	Hang the weight to the retort stand using a thread. What do you notice? Repeat this experiment using a metal wire.
2	Scratch the metal ruler against the plastic ruler. What do you notice? Now, this time, scratch the plastic ruler against the metal ruler.
3	Bend a plastic ruler. What do you notice? Repeat again the experiment using a wooden stick.
4	Pour water into a beaker. Then put a ping pong ball, a match stick and an eraser into that beaker of water. What do you notice?
5	Pour water into a beaker. Then put a scoop of salt, sugar and sand using the spatula into the beaker of water and stir them for about 30 seconds. What do you notice?

Lesson Plan

gee HZ — Sun, 16 Nov 2008 23:28:20 +0000

Day: Monday

Date: 5^th May 2008

Time: 8.45 – 9.45 am

School: Sekolah Rendah PSN PMY, Seria

Year: 4 Great

No. of pupils: 25 pupils

Themes: Variety and Classification [Unit 4 Variety of Materials]

Topic: Properties of materials

Previous knowledge:

Pupils have learnt the seven different kinds of materials and its uses. They are able to state and classify each material into its different categories.

Objectives: At the end of the lesson, the pupils will be able to:

investigate and state the properties of materials [strength; hardness; flexibility; floating or sinking and solubility] in the experiments that they have gone through.
cooperate and work together among peers in completing their group tasks.
appreciate the great variety of the materials around them and the different properties of each material.

Teaching and Learning:

Introduction:

Teacher reflects back on the previous lesson on different kinds of materials by posing the questions below:

Question: Can you tell me how many different kinds of materials that we have learnt before?

Expected Answer: 7

Question: Name all the 7 classes of materials

Expected Answer: Wood, rubber, metal, glass, plastics, fabric and ceramic

Question: Give two examples of things that are made up from rubber.

Expected Answer: Balloon and tyre

Question: Give two examples of things that are made up from plastics.

Expected Answer: Plastic bag and food container

Teacher pick one pupil by random to briefly describe a metal ruler (given by teacher) whether it is hard, soft, bendable and et cetera. Teacher writes down the pupil’s description on the board. Again, teacher picks another pupil to do the same observation as before by given the pupil a piece of rubber band. With those answers, teacher then introduces the topic “Properties of Materials”.

Main Activity:

Teacher divides the class into 5 groups in which they are going to investigate the properties of materials through real experiments. 5 different stations for dissimilar experiments have been organized by the teacher. Recording sheets will be distributed and directions of tasks will be stated clearly before any experiment can be set off.

INVESTIGATIONS:

In station 1, pupils need to find out which material is stronger either cotton thread or metal wire. They will have to hang the weights using the two materials on the retort stands.

Expected conclusion: Metal wire is stronger than cotton thread.

In station 2, pupils need to find out which material is harder either metal ruler or plastic ruler by scratching it to one another.

Expected conclusion: Metal ruler is harder than the plastic ruler.

In station 3, pupils need to find out which material is having the property of flexibility either a plastic ruler or a wooden stick by bending those two materials.

Expected conclusion: The plastic ruler is flexible as it can be bend without breaking.

In station 4, pupils need to find out what will happen to the materials such as ping pong ball, match stick and eraser if it is put into the water.

Expected conclusion: Ping pong ball and match stick are lighter compare to eraser. Therefore, light material floats and the heavy one sinks.

In station 5, pupils need to find out what will happen to the materials such as salt, sugar and sand when they are put inside the water and being stirred.

Expected conclusion: If there is no more substance seen, it has dissolved/soluble in the water and if it does not dissolve, it is insoluble in water.

One or two group(s) will have to do a quick presentation on their findings.

PRACTICE:

Teacher groups the interactive activities according to the pupils’ abilities: high achiever, average achiever and low achiever. Allowing the pupils to practice using those sites may broaden their knowledge, values and skills in learning the general concepts of materials outside from the school syllabus.

Conclusion:

Teacher sums up the lesson by recapping the properties of materials. Homework sheet will be given to the pupils before the lesson ends.
