Water Properties
What is the biggest water storage we have on our planet?
The Ocean!
This is the state of matter that keeps its shape and doesn’t flow.
Solid
True or False: Good bacteria can also help protect us from bad bacteria.
TRUE
This is the part of the water cycle when water falls from the sky as rain, snow, or hail.
Presipitation
What would happen if we didn't have any bones?
We wouldn't be able to stand up or move around because we would not have any structure.
I filled my water bottle and I thought it would spill, but it didn't! It formed a dome on top. Why did this happen?
Surface tension!
It's a force that makes the top layer of a liquid act like a stretchy skin. It happens because the water particles hold tightly together. This is why small things, like bugs, can sometimes sit on water without sinking!
This state of matter takes the shape of its container but keeps the same amount.
Liquid
What organ in your body breaks down food with strong acids?
The stomach
This process happens when the sun heats up water, turning it into vapor.
Evaporation
What is the difference between voluntary and involuntary muscles?
Voluntary muscles are the ones we can control (like moving our arms), and involuntary muscles work without us thinking about it (like our heart beating).
True or False: When you swim in the sea, the water gets hotter the deeper you go. This is because water contracts and goes to the bottom when it heats.
FALSE: Hot water expands and stays at the surface of the water, so the deeper you swim, the colder the water gets.
This state of matter spreads out and fills the space it’s in.
Gas
What are two foods that has good bacteria in it?
Yogurt and cheese
This happens when water vapor cools down and forms tiny droplets, creating clouds.
Condensation
Which muscle works all day and all night without stopping?
The heart
Draw on the whiteboard the particles according to the three states of matter:
Teacher will assess!
When you heat ice, it changes from this state to a liquid. What state was it in firstly?
Solid
What is the long, coiled tube where most nutrients from food are absorbed?
The small intestine
This is the name of the full process where water moves from the Earth to the air and back again.
Water cycle
What bone protects your brain?
The skull
I left two wet towels outside for an hour! One towel was under the shade and the other was under the hot sun. Which one would be dry and the other not?
It would be dry because of the sun being directly on it, making it hotter so water evaporated quicker. The other one would take longer to dry.
This process happens when water changes from a liquid to a gas.
Evaporation
Why is it important for our bodies to absorb nutrients from the food we eat, and how does that help other body systems?
Absorbing nutrients gives our bodies energy and helps our muscles grow strong, keeps our bones healthy, and supports the work of all our organs.
What step of the water cycle is reversible? Explain your answer
Evaporation
Condensation
Precipitation
Collection
What do skeletal muscles need to work properly? (Hint: It's something we eat and drink.)
Nutrients and water.
