Real Life Science Experiment

Get Poppin' With Bubbles!

For this real life science project, my partner Cassie and I choose to create a human bubble. Below are some pictures with text and a link as well so you can share the experience with us!

Bubble Experiment

Materials Needed:

Small pool

Hula Hoop

Dish washing liquid

Glycerine

Water

After filling the pool with water, dish washing liquid was added to help make the bubbles.

Glycerine was then added to the mixture.

Here was our first atempt to cover a human with a bubble. As you can see the hula hoop is too small and the bubble is closing in on me, as we pull the hula hoop up.

We then had to upgrade to a bigger hula hoop and a bigger pool so that the experiment would work correctly.

Look! There is a human covered in a bubble.

Welcome to Our Science Lab!

Dear Parents and Guardians:

For the next month we will be blowing the science lab up! We will be focusing on different topics in our science class. For each lesson, the students will be engaged in an experiment that pertains to the lesson. The purpose of these experiments is to give the students hands on experience and to help them understand the lesson better. Provided in the posts below are pictures and step by step directions of some of the experiments that will be completed in class. Feel free to explore! If you have any questions or concerns, please contact me either in the comment box below or at my e-mail address lilfal_23@hotmail.com.

First we want to ask ourselves what is refraction? Refraction is the bending of a wave when it enters a medium where it's speed is different.Refraction is responsible for image formation by lenses and the eye. Refraction makes objects appear different, for example a ruler looks bent when standing in water.

Falon's Project

See Double - Experiment 1

Use water to turn ONE button into TWO!

(p.g 41)

Materials Needed:

1.) Glass

2.) Water

3.) Button

Here I am placing the button into the glass.

The button needs to be placed right in the middle of the glass.

Here I am pouring water very slowly into the glass.

LOOK.. There is TWO buttons!

Falon Muncy - Taste Test

TasteTest

(p.g 71)

Materials Needed:

• Three small glasses
• Three different types of pure fruit juice
• Large glass of water
• Bandanna
  

Have a friend blindfold you with a scarf.

1.) Orange juice

2.) Apple juice

3.) Apple rasberry

Without holding your nose taste each juice. It is easy

to recongnize the flavors. (Apple rasberry)

(Orange juice)

(Apple)

After tasting each juice, wash your mouth out with a
glass of water.

Hold your nose and taste the juices again!
(Apple)

(Orange juice)

(Apple rasberry)

It is more difficult to identify the juices while holding
your nose! Cassie thought so! The juices now
have similar flavors.

Falon Muncy - Scientific Explanation (Taste/Smell)

Scientific Reason for Taste/Smell

Don't blame your taste buds when your food loses it's flavor. Blame your stuffed up nose! Did you know that around 70% we actually taste comes from our sense of smell. Bitter, salty, sweet, and sour flavors are perceived by our taste buds. When you put food in your mouth, odor molecules from that food travel through the passage between your nose and mouth to olfactory receptor cells at the top of your nasal cavity, just beneath the brain and behind the bridge of the nose. If mucus in your nasal passages becomes too thick, air and odor molecules can't reach your olfactory receptor cells. Your brain receives no signal identifying the odor, and everything we eat tastes similar. Of all our senses, smell is most primal.

Weigh Some Air

Weigh Some Air

(pg. 8 in experiment book)

People often use the expression "Its light as air". But the question is... Is air really light?

Background Information

Air is not empty space. It is made of matter - mainly different types of gases. The normal composition of air is about 78% nitrogen (N2), 21% oxygen (O2), and 1% other gases such argon (Ar), carbon dioxide (CO2), methane (CH4), and helium (He). Many gases are composed of molecules that are made up of atoms, the fundamental units of matter. Some gases are just made up of atoms. Air is essentially a layer surrounding the Earth made of of trillions and trillions of gas molecules.
Air also contains solid particles (e.g., dust, ash, etc.), water droplets, and ice crystals. These materials are also comprised of molecules that are made up of atoms. However, these materials are not considered part of the normal composition of air. Nevertheless, collectively, air is made up of matter such as gases, solid particles, water droplets, and ice crystals. All matter occupies space and has weight.

Purpose

To demonstrate that air has weight. The lesson is important for building a foundation regarding matter and its fundamental units, air and its properties, and air pollution concepts. The lesson also helps students begin developing observation and prediction skills.

Materials needed:
Balloon pump, Two tacks, Two balloons, Rubber band, Long thin piece of wood, Ruler, Pencil, Tape, Thread

1.) Use the ruler to find the center of the wood and then mark it.
2.) Push a tack into each side of the center mark.


3.) Tie the thread to the middle of the rubber band.

4.) Fix the loops of the rubber band around the tacks. Lift the wood by the thread. It should
balance.

5.) Tape one of the balloons to one end of the wood.


6.) Tape the second balloon to the other end of the wood. Check that it still balances. Then remove one balloon and blow it up.
(Look.. It still balances)


7.) Pump air into the balloon before placing it onto the stick.
Predict whether the inflated balloon will be heavier, stay the same, or be lighter than the deflated balloon.


8.) Tie the blown-up balloon and attach it to the wood in the same place using tape. The balloon makes the wood lose its balance.
Was your prediction accurate?
(When the balloon has been inflated, it becomes heavier because it contains air.)

Follow Up

Explain that the balloons and balance demonstrated that air has weight (and occupies space)because the side of the balance with the more air-filled balloon dropped lower than the side with the more empty balloon. Explain that air is not empty space, but is made of gases such as nitrogen,oxygen, argon, carbon dioxide, methane, and helium; solid particles such as dust, smoke, and ash; water droplets; ice crystals; and many other materials. These materials, or matter, are composed of very small units called atoms. All matter occupies space and has weight.
