Whats the Challenge?With the use of red cabbage extract, you will

test the pH of each of five mixtures in liquid

form to determine if it is acidic or basic.

What you need

o red cabbage extracto plastic droppero 5 unknown mixtures (each contained in a

plastic cup)

Hands-on

1. Add five drops of the red cabbageextract onto each of the five plastic cupscontaining a mystery mixture. Swirl the

content of the plastic cup thoroughly.2. Determine the pH of the resulting mixture

by referring to the figure below.

3. With the use of your sense of smell, identifyeach of the five mystery mixtures. (HINT:

Each mixture is a common or familiar

household product mixed with water.)

Based on observations

1. Which of the five mixturesis/are acidic? Basic?

2. What is the identity of eachmixture?

3. How many phase(s) doeseach mixture show?

Identify the phase(s).

4. Each mixture is composedof a common household

product mixed with water.

Which between the

household product and

water is the solute and

which one is the solvent?

(NOTE:Solute is the part of

mixture which is smaller in

amount; solvent is the partin bigger amount.)

How does it work?

The essential concept

is

Each of the five mystery mixture

classified as a solution. Based

your responses to prompts 3 and

describe in one sentence whasolution is.

The Sciencebehind

Red cabbage contains a pigment molecule called

(an anthocyanin).

Very acidic solutions will turn anthocyanin red in

Neutral solutions result in a purplish color. Basic s

appear in greenish-yellow. Therefore, it is poss

determine the pH of a solution based on the color

the anthocyanin pigments in red cabbage extract The color of the extract changes in response to cha

its h dro en ion concentration.

Whats the Challenge?

You will make a liquid mixture of cornstarch

and water turn into solid by tapping on it. Themixture is known as an Oobleck!

What you need

o corn starch (about cup)o water (about cup)o food coloringo mixing bowlo newspapero spoono plastic cupHands-on

1. Place a sheet of newspaper flat on thefloor; put the mixing bowl in the middle ofthe newspaper.

2. Add cup of dry cornstarch to the bowl;then, add about 1/8 cup (2 tablespoons)of water (added with food coloring) to the

corn starch and stir slowly. (Add water

slowly to the mixture, with stirring, until allof the powder is wet.)

3. Continue to add water until thecornstarch acts like a liquid when you stir

it slowly. When you tap on the liquid with

your finger, it shouldn't splash, but ratherwill become hard.

(NOTE: If your mixture is too liquid, addmore cornstarch. Your goal is to create a

mixture that feels like a stiff liquid when youstir itslowly, but feels like a solid when you

tap on it with your finger or with a spoon.)


1. What happens to the

Oobleck when you

rub it between your

palms? When youyou stop rubbing?

2. After leaving the

cornstarch mixture in

a plastic cup for

some time, what can

be seen at the

bottom of the plastic

cup?

How does it work?


is

Scientists call Oobleck a non-Newto

fluid (just like ketchup and quicksand).

In an Oobleck, the cornstarch is suspen

in the water (instead of compl

dissolving, just like sugar or salt).

Applying a force to the Oobleck sque

the water out from between the cornst

bits. Pulling or pouring the Oobleck, on

other hand, gently lets the water

between the cornstarch bits.

The Sciencebehind

An Oobleck is classified as

suspension rather than a solut

Based on your response to promp

what then is a suspension?

You will create a lava lamp by making

colored blobs floatin a mixture!

What you need

o 1-liter clear soda bottleo cup watero vegetable oilo fizzing tablets (ex. Alka Seltzer)o food coloringo funnelo flashlightHands-on

1. Pour the water into the bottle.2. Using a funnel, add the vegetable oil into

the bottle until it is almost full.3. Add ten drops of food coloring into the

bottle.4. Break a seltzer tablet in half and drop the

half tablet into the bottle. Watch it sink to

the bottom and let the blobbygreatnessbegin!

5. To keep the effect going, just add anothertablet piece. (NOTE:For a true lava lamp

effect, shine a flashlight through the

bottom of the bottle.)


1. What happens to the

vegetable oil when it is

added to water?

2. To which does thefood coloring mix, with

water or with oil?

3. What are the colored

blobs made of?

4. On which part of the

mixture do the colored

blobs float as the

seltzer tablet is added?

How does it work?


is

The Sciencebehind

Water and oil do not mix (they are said toimmiscible liquids) so when we add oil to

water, the water sinks to the bottom of

bottle, while the oil settles at the top.

The food coloring mixes with the water

does NOT with the oil.

The Alka-Seltzer tablet reacts with the wa

making bubbles of carbon dioxide gas. Th

bubbles attach themselves to the colo

water making them float - hence the l

lampeffect.

The mixture consisting of the colored wa

blobs floating on oil in the lava lamp

classified as an emulsion.

What is the similarity and what is

difference between an emulsion and

suspension? (HINT:Consider the phases

the individual components of the mixture

o 50 mL ( cup) milko 50 mL ( cup) whipping creamo 25 mL (5 tsp) sugaro 0.5 mL (1/8 tsp) vanilla or vanilla flavoringso 100-175 mL ( cup) salto 500 mL (2 cups) ice cubeso one 1-L (1 quart) zip-top bago one 4-L (1 gallon) zip-top bago spoonHands-on

1. Place the pre-measured sugar, milk,whipping cream and vanilla into the

smaller zip-top bag; seal the bag securely.2. Put the ice cubes into the larger zip-top

bag. Add salt to the bag of ice.3. Place the sealed smaller bag inside the

larger bag of ice and salt; seal the larger

bag securely.

4. Gently rock the larger bag from side toside. (Caution: Hold the bag by the top

seal as the bag gets too cold throughcontinuous shaking.)

5. Shake and rock the bag for 5-10 minutesor until the content of the smaller bag hassolidified into ice cream.

The Sciencebehind

Milk with dissolved sugar and whipping c

When salt is added to ice, it dissolves in the

Thus, the salt and ice mixture gets much cold
