physical and chemical property and physical and chemical changezahid ullah
The document defines physical and chemical properties and changes. It states that physical properties can be observed without changing the substance's composition, and includes intensive properties that do not depend on amount and extensive properties that do. Chemical properties describe a substance's ability to change into a new substance through a chemical reaction. The document distinguishes between physical changes, which alter a substance's state or form without creating a new substance, and chemical changes, which produce new substances and are generally not reversible through physical processes alone.
1. The document outlines a microteaching lesson plan on states of matter for students.
2. It includes warm up activities like hangman to review key terms, matching properties to solids, liquids, and gases.
3. A modeling activity uses balls to demonstrate the movement and bonding of molecules in solids, liquids, and gases.
4. Students then answer questions about the models and watch a video defining additional vocabulary before consolidating their understanding.
Chemical and physical changes are distinguished by whether the original matter remains. A chemical change results in new substances as the original matter cannot be recovered, such as when baking a cake. A physical change involves the same matter, just in a different state or form, like boiling water where the same amount of H2O remains.
This lesson plan outlines a physics lesson for 9th grade students on states of matter and their interconversion. The lesson uses various activities and experiments to help students differentiate between solids, liquids, and gases, understand their characteristics, and observe how changing temperature can convert one state of matter to another. The plan includes objectives, materials, teaching methods, questions for discussion and formative assessment, demonstrations, experiments, and a summative assessment at the end to check student learning.
The document discusses physical and chemical changes. A physical change alters a substance's physical properties but does not create a new substance, such as melting ice. A chemical change produces a new substance through a chemical reaction, like cooking or burning. Chemical reactions have reactants that interact to form products, and there are four main types of chemical reactions: combination, breakdown, precipitation, and combustion. The rate of a chemical reaction can be affected by factors like surface area, temperature, and concentration of reactants. Catalysts are substances that increase the rate of reactions without being used up in the process.
1. The document outlines a 45 minute chemistry lesson plan for 8th standard students on the topic of reactants and products.
2. The lesson involves discussing definitions of reactants and products, demonstrating reactions through activities like burning magnesium ribbon and heating potassium permanganate, and having students write observations and answers to discussion questions.
3. The goal is for students to develop knowledge of reactants and products by recalling examples of reactions and identifying reactants and products, explaining the concepts, and showing understanding through activities, questions and writing.

Ask students what they know about solids, liquids, and gases. Use various Lego configurations
to show how the molecules in solids, liquids, and gases are organized differently. Start by
building a set that is compact, like a rectangle, portraying a solid, where the molecules are close
together. Next start pulling Lego pieces off one by one showing that molecules in a liquid have a
little more freedom and energy to move around. To demonstrate gas molecules, throw the Legos
in the air in all directions. Explain to the students that the molecules in a gas don’t want to be
next to one another so they disperse in any direction possible. Also explain to the students the
different energy levels each phase state has; solids have a low energy, liquids a little more, and
gases have the most.
Once the students understand these properties of matter, ask them how matter changes between
the different states. Use the analogy of Legos again. Build a solid cube out of red blocks and
another out of blue blocks into a rectangle.
-For a physical change, show the beginning solid pieces. Then piece by piece take them
apart and explain that it is now a liquid. Finally move the Legos in all directions for a gas. Note
that the molecules never changed, just changed phases.
-For a chemical change, use the red and blue cube sets. Explain to the students that they
are different molecules, the red being a solid and blue a liquid. Then put some energy into the
molecules and start to break them apart and add combine both blocks together to form one cube.
Explain to the students that the two colored block acts like a liquid solution such as salt water.
Finally put more energy into the molecules and pull them apart and spread them out from one
another. This is creating a gas and the molecules want to get as far away as they can.
Demonstrate more physical changes by using the following experiments.
-Ask the students how much snow they get where they live. Then ask them what their
parents do after they have shoveled snow from the sidewalks. Explain to them the purpose of
putting rock salt on the sidewalks. The rock salt lowers the freezing point of the water and
therefore, the ice melts and becomes a liquid. This is a physical change.
-Show the students some ice and water in separate containers. Ask them the difference
between the two and if the molecules are the same. Explain that the difference between the ice
and water is due to the amount of energy that is in them and that it is a physical change. Then
ask the students what happens when they boil water at home. Explain to them that the steam that
comes off the water is just water in a gas form and can condense back down to a liquid again
once the temperature has cooled down. These physical changes happen when heat is either
added or taken away. Ask the students if they can think of any other physical changes. Other
examples may include crumpling a piece of paper, cutting open an apple, inflating or deflating a
basketball, breaking glass, or breaking a pencil.

4. Demonstrate more chemical changes by using the following experiments and explain that
chemical reactions occur when molecules of matter are combined to make a new substance.
Also some clues to tell if a chemical change has occurred include a change in smell, light or heat
is given off, or production of bubbles or gas. Some examples include fire, rust, baking, fall
leaves changing color, and moldy cheese.
-Add some vinegar to a beaker and ask the students what type of state it is in. Next show
the students some baking soda and ask what state it is in. Then add some baking soda to the
vinegar and put a balloon over the beaker opening. This will cause the mixture to react and
bubble up causing the balloon to fill up with a gas called carbon dioxide. Ask the students what
type of change just occurred and what they think is in the balloon. This will help them see the
change from a solid and liquid state to a gas state. This will also help them understand that
although a chemical change has occurred, none of the material that went into the experiment
disappeared, it just changed state.
Assessment
A performance based assessment would follow this activity. Perform the baking soda and
vinegar experiment again for the students to solidify the understanding of physical and chemical
changes as well as the states of matter. Start by adding vinegar to a beaker and ask the students
what state the vinegar is in. Then add green food coloring to the vinegar and ask what type of
change occurred, physical or chemical. It is a physical change. Show the students some baking
soda and ask them what state the baking soda is in. Then add some baking soda to the vinegar
and ask the students if this is a physical or chemical change and why. This is a chemical change.
Extensions
-Add a few drops of food coloring to some water and ask what type of change this is. It is a
physical change. Then add bleach. This will clear up the water in a few minutes. Ask what type
of change just happened, chemical or physical. This is a chemical change. Next add baking soda
to water and ask what type of change, chemical or physical. This is a physical change due to its
solubility. Finally add baking soda to vinegar and ask what type of change this is. It is a
chemical change.
-Explain to the students what a control factor is in an experiment. Ask the students what they
think happens when you bake a loaf of bread and the reaction that takes place. Then have them
make four different loaves of bread at home. One with the correct amount of yeast, another with
no yeast, another with half the amount of yeast, and the last with double the amount of yeast.
Have the students bring the loaves to class and discuss the differences in the loaves due to the
various amounts of yeast. Also have them come up with a hypothesis or conclusion for the
reaction differences due to the varying amounts of yeast.
