This is aimed for younger children but older children and teenagers should enjoy doing this science experiment. It mentions "capillary action" and "cohesion" which are two properties of water.

Scientific Method
There are many steps in the scientific method. Usually you will find six steps in the method but there can be more.
Here are the basic steps in this method.
Observe
Use your senses to observe what is taking place around you.
Ask a question.
Why or How?
Hypothesize
To hypothesize is to form a hypothesis. A hypothesis is an educated guess or prediction about what causes something to happen. The plural of hypothesis is hypotheses.
Make a prediction based on your hypothesis
A prediction is what you think will happen if… It is something that might or might not happen when you test your hypothesis.
Think: If I do this, then ___ will happen.
Example
If I freeze salt water, then ___ will happen.
If I freeze fresh water, then ___will happen.
Experiment
You will need to test the prediction. Observe or perform experiments based on your prediction (hypothesis). Find out if your hypothesis is correct.
Conclusion
You will need to come up with a conclusion. You will decide how your test results relate to your predictions. Was my hypothesis (guess/prediction) correct?/incorrect?
Reflect/Communicate
You need to reflect. If the hypothesis was supported then one might need to go through some more tests of the experiment to see if it can confirmed. If the hypothesis was not supported then a new hypothesis would need to be made.
Talk with others (or yourself) about the results. Test the hypothesis many times. Have others test the hypothesis. The scientific method steps will need to be repeated more than once to see if the hypothesis is true or false. Remember, will the results come out the same when repeated again?
Of course, there are more steps but these are main steps to remember.
This is what my daughters 9th grade Conceptual Science teacher taught her class.
O - Observe
H - Hypothesize
E - Experiment
C - Conclude
Remember, the basic steps are:
OBSERVE
QUESTION
HYPOTHESIZE
EXPERIMENT/TEST
CONCLUDE
I like the steps the teacher gave my daughter (OHEC). If you remember those steps then you can just remember to question the things you observe.

I was making a glass of lemonade. As I was stirring it. I observed it was making various notes. At the bottom of the glass it was making a higher note. At the top of the tall glass, it was making a lower note. As I drunk my lemonade, it was making a higher note when I stirred it. It kept on getting higher and higher as I drank the lemonade. It did stop changing notes at a certain point. If you are making lemonade (or if you just want to do this with water or any other type of drink). Have fun!
This also works with any height of a glass cup or bowl or even plastic cups or bowls.
Plastic Cup Sound Experiment
This is the safest with kids.
Materials:
- Various sizes of plastic cups
- Spoons
Take various sizes of cups. Use the scientific method. Predict what will happen with each size of cup. Will it be a high note? Will it a low low? What will it be? Test your hypothesis out by having the child, teenager, or adult tap a spoon on the top of the different sizes of bowls. What will happen if you add water to each cup? Predict what will happen. Illustrate your experiment.

Clouds Thematic Unit
I will be adding more resources to this page.
Here is a poem I just wrote on May 20, 2020 about clouds.
Clouds
Clouds are high.
Clouds are low.
Clouds are big.
Clouds are small.
Clouds are white.
Clouds are gray.
Clouds are fluffy.
Clouds are floating everywhere in the sky.
Are there clouds in the sky today?
Take a look,
What kind of clouds are there today?
Clouds are everywhere in the sky.

Egg Experiments
Here are some experiments you can do with eggs. Have fun!!!
The Disappearing Egg Shell/Naked Egg Experiment
Do you want to see an eggshell disappear like magic? Let's see it happens.
Materials:
Raw eggs
Vinegar
Glass jar with lid
Spoon
Food coloring (optional)
Experiment: Add vinegar to a jar (with a lid). You will need to make sure you will be able to cover the egg completely with vinegar. You can add food coloring to the vinegar if you like. If you use food coloring, add some food coloring to the vinegar and stir with a spoon. Place a raw egg on a spoon and place gently inside the jar, Seal the jar tight. (Note: Remember to wash your hands after touching a raw egg.) Observe and see the bubbles form. More bubbles will form around the egg as days goes by. (The egg will turn around.) Observe it each day to see what happens. This will be until the bubbles almost completely disappear. Remove it from the bottle of vinegar. As you touch it, it will feel rubbery. Save it for the next experiment.
Here are some photos I took back in April 2003. I didn't take anymore photos when the eggshell was totally dissolved.
April 23 12:05 a.m.
April 23, 2003 10:49 a.m.
As you can see, the eggshell is starting to disappear (dissolve). You can see what happens when you place an egg in vinegar. It will turn a light brown color as you can tell in the photos. A chicken eggshell contains between 95-97% calcium carbonate. Human teeth contain hydroxyapatite, which is crystalline calcium phosphate. This is one reason why they say to dilute vinegar if you are going to drink it. Vinegar will eat you teeth just like it will eat an eggshell.
Bouncing Egg Experiment
Do you want to have some fun with the egg where the shell disappeared like magic? Well, we are going to have some fun now.
Experiment: Use your egg without a shell. Bounce the egg on a plate. (Caution: Make sure you don't squeeze it with your fingers or it will break-unless you want to.) It will only bounce a little bit before it breaks. Note: Remember to wash your hands after touching a raw egg.
Spin An Egg Experiment
Have you ever wondered if an egg is cooked or raw? Well, you can do an experiment to find out.
Experiment: Lay an egg on a smooth, hard surface. Take an egg and gently spin it using your fingers. Observe if it spun fast or if it wobbles and moves slow. A hard boiled egg will spin. The raw egg will wobble and hardly move at all. This is because the raw egg has liquid inside. Note: Remember to wash your hands after touching a raw egg.
Test An Egg For Freshness Experiment
Place a raw egg in a container of water.
If it sinks to the bottom, it is the freshest,
If it sinks down almost down to the bottom, it is still fresh. (It may be about a week old or so.)
If it floats, it is a bad egg (at least three weeks old).

"A" Science Experiments and Activities
A
Absorb - Put a sponge in water. Observe the water absorb into the sponge.
Air
Blow a feather across the floor.
Put some water into a container and blow on it.
Blow on your hand.
Blow a balloon up. Play with it.
Air in a Bag
Materials:
Straw
Book
Zipper Sandwich Bag
Predict what will happen when you blow air into the bag. Take a straw and place it in the center of a plastic bag. Seal it on the sides towards the straw. Place it under the book. Blow into the straw. Observe what happened.
Air Pressure
Experiment - Fill a sink (or container) of water (enough to cover the cup). Have the child(ren) predict if water will go in the cup or not. Push a clear plastic cup into the water. Take the cup out of the water. Did any water get into the cup? Was the cup heavy or light? After doing that several times, let the children experiment with the cup and let water enter into the cup. Was the cup with the water in it heavier or lighter than the cup with "just air" in it?
Astronomy - Look outside during the day or the night. What do you see?
