液体のpropertiesを発見する実験と結論です。
INSTRUCTIONS (What you have to do):
1. Work in groups. Each group MUST test a different liquid.
2. Select someone in your group to collect a liquid in a container from the teacher. Each group must also collect another empty container and a saucer from your teacher.
3. Answer these questions while you are studying your liquid.
Write your answers in the table that follows. DO NOT TASTE THE LIQUID!
• How does it smell?
• Can you put your finger through it? • Is your hand dry or wet feeling the liquid?
• Can you soak the liquid up with a cloth?
4. Put a small amount of the liquid in the saucer and leave it for a while in a warm place.
• Was it easy to pour the liquid from one container to another?
• Can the liquid flow or spread out on a saucer?
• How will you describe the shape of the liquid, is it fixed does it take the shape of the container?
• Did the amount of the diｆｆerent liquids remain the same after leaving them in a warm place?
5. WASH YOUR HANDS AFTER HANDLING THE LIQUID

After doing this activity where we investigated the properties of liquids, we can say that a liquid:
• can flow,
• it has no fixed shape,
• and it takes the shape of the container that it is in.
This is different to a solid.
Remember a solid has a fixed shape and you cannot pour a solid!
