حل درس solids liquids and gases العلوم منهج انجليزي الصف الخامس
MAKE YOUR CLAIM
How do the three states of matter change shape
Make your claim. use your investigation
CLAIM Solids Liquids
Sample answer: keep their shape; take on the shape of the container; expand to fill their container
Cite evidence from the activity
EVIDENCE
The investigation showed that
Sample answer: the gas pushed against the closed syringe as I pushed the plunger down. The solids had a definite shape and the liquid took the shape of each container Into which it was poured
Discuss your reasoning as a class. Tell about your discussion
REASONing
The evidence supports the claim because
Sample answer: the particles in a gas spread far apart When pressure is added, the particles condense. The particles in a solid are packed tightly together and hold their shape. The particles in a liquid are able to move and take the shape of their container
You will revisit your claim to add more evidence later in this lesson
States of Matter
VOCABULARY
Look for these words as you read
gas liquid solid
State is another physical property of matter. Solids liquids. and gases are common forms that matter

can take. Each state has specific characteristics
A solid has a definite shape and takes up a definite amount Of space. A solid stays in its definite shape with a definite volume unless it is changed by an outside force
The particles in a solid are tightly packed together and vibrate in place. They are often packed in a regular pattern. A "quid has a definite volume. but it does not have a definite shape. It can be poured from one container to another. The liquid fills the shape it is poured into from the bottom up. The particles in a liquid are usually less tightly packed than those in a solid and can move and slide past one another. One example in which this is not true is water
Water is actually more dense than ice a definite shape
: No matter what type of container you put them in they will still keep that The liquid being poured from this bottle is able to now because it does not have a definite
Because the : basketban is a sphere the air inside of it will be sphere shaped too
Gases have no definite shape Or volume. The particles in a gas are much farther apart than particles in solids or liquids. They can move around each other very easily. Gases spread out and completely fill a closed container. If you make the container bigger. the same amount Of gas will expand to fill it
Changing States of Matter
The average movement of particles in an object is determined by the amount of energy in the object. Temperature is a of this movement. When energy is added. the particles move faster. When energy is lost, the particles move more slowly. When enough energy is gained or lost. there is a change of state
Adding Energy When energy is added to a solid, the particles start to move more quickly. When the particles move quickly enough that they slide past other. the solid a liquid by melting. If even more energy is added to this liquid. the continues to increase and they move away from each other As the particles spread out enough, liquid becoming a gas
Removing Energy If a gas loses energy. its particles slow down and move closer together. They start to slide past each other again. A liquid forms through a process called condensation. If the liquid loses enough energy. freezing and a solid forms
Label a Diagram use information that you read to the states of matter in the above. Label the process of how each state Of matter Changes from one to the other
COLLECT EVIDENCE
Add evidence to your claim on page 55. Use what you have learned the changing states of matter to add evidence and reasoning to your claim

Pharmacy technicians work in hospitals and pharmacies. They work closely with pharmacists and people in the health industry. Some technicians are responsible for inputting prescription orders given over the phone or in person, They take orders from both patients and health care providers. Pharmacy technicians are also responsible for counting pills, mixing medicines. and labeling prescriptions
Pharmacy technicians need to have good communication skills as they interact with patients on a regular basis. They relay information from the pharmacist to patients
They give out prescription medication and medical devices to patients. They explain how to use the prescription. what it is for, and how often to take it. They also explain what the patient can expect when taking a prescription
Model Matter
You have learned about the three main states of matter and how the organization of their particles affects how they behave
Choose an object for each of the three states of matter. Draw each object. use unit cubes to develop and use a to show the scale Of the volume and number of particles in the object and how the particles in each object are organized. Add this information to your drawings. Below each mcxiel. how the arrangement of the particles determines the properties of each of the objects
EXPLAIN THE PHENOMENON
What are the different forms in which matter can appear
Summarize It
Use what you have learned to explain what you know about the particles. in solids. liquids. and gases. Use the to write a summary or draw a diagram of what you learned
Sample answer : The particles in a solid are tightly packed together and vibrate in place The particles in a liquid are less tightly packed than those in a solid (except for water) and can move and slide past one another. The particles in a gas are far apart and can move around each other very easily
