Science - Acids and Bases

Hello Bloggers, 

For literacy, we have been learning about acids and bases. We got to do some cool science experiments and we had to create a science report on science experiments. Here is my science report and see ya.

Acids and Bases

Questions:

• What are the properties of acids and bases in the water?

Research Summary:

Acids and bases are in everything around us even in water. The scientific name for water is h2o. The h stands for hydrogen, the 2 stands for 2 hydrogens and the 0 stands for the oxygen. Now these are all connected, for example, if you have tasteless water and it is bland then all of the molecules are connected but they do disconnect and it will taste bitter, that is when it is more of a base than acid, but if there are too much-disconnected molecules than it is more of an acid.

Hypothesis

Hypothesized pH	5	1	8	6	9	10
Chemical Product	Sprite	Ammonia	White Vinegar	Lemon Juice	Alcohol	Baking Soda

-Materials:

We used:

• Cabbage Juice - as the solution indicator

• Sprite

• Ammonia

• Lemon Juice

• Alcohol (Hand Sanitizer)

• White Vinegar

• Baking Soda

• Test Tubes

• Pipettes

• Teaspoons

Procedure:

Set aside your indicator solution. You will use it as your "stock" solution for your experiments.

Next, you will test various household solutions with your indicator.  Use one beaker for each solution you want to test because you do not want to mix chemicals that do not go well together or contaminate your results.

Place an equal portion of indicator solution and the test liquid (eg. Vinegar) into a beaker.  Use a pipette to measure this.

Add drops of a liquid you want to test until you see the solution change in colour. Gently swirl the cup as you add the drops, being careful not to spill the solution.

Record the observed pH and a description of 

each solution in a data table in your lab notebook.

Analyze your results. How does the pH of the different household items you tested compare to each other? Are you surprised by any of your results?

Observations/Results:

Actual pH	3	11	3	2	6	8
Observed Colour	Violet	Green	Pink	Red	Purple	Blue
Chemical Product	Sprite	Ammonia	White Vinegar	Lemon Juice	Alcohol	Baking Soda

Discussion:

For the baking soda experiment, it reacted differently. The baking soda absorbed some of the cabbage juice and made it turned into a light blue, but the leftover that was sitting on top, it turned a dark blue.

With the Alcohol, we used hand sanitizer so it also was different from the other experiments. Hand sanitizer is quite gluggy, so it floated up to the top and some of it still stayed the same only if you didn’t stir it around. 

Now with the ammonia, it reacted completely differently. As soon as we tipped the cabbage juice into the ammonia, it foamed up fully and then it calmed down and then changed colour completely. 

Conclusion:

For this experiment, all of the chemicals reacted really differently and worked perfectly perfect. It wasn’t what we all expected but it worked very well as we got a lot of evidence.

Allergic Shopping List / Space Tic Tac Toe

Hello Bloggers, 

For Wednesday activities, we had to create a shopping list. We had a budget of $170 and we had to feed 4 people but there was a catch. Steve had no allergies, George was dairy-free, Patricia was gluten-free and Dave was vegan. Here is a slide with my list. 

For Inquiry, we have been learning about space. We had to complete 3 tasks about space. Here is one of mine for the week and later. This is about astronauts everyday life.

Astronauts Everyday Life

How they go Toilet

Astronauts can urinate into a long tube with a vacuum system sucking away the waste or they can sit down on a special space toilet

How they Shower

On the International Space Station, astronauts do not shower but rather use liquid soap, water, and rinseless shampoo. They squeeze liquid soap and water from pouches onto their skin. Then they use rinseless soap with a little water to clean their hair

Can they Charge Devices

It has no phone number in the traditional sense, and astronauts have to leave their smartphones at home. For private calls, the space station has an internet-connected phone system that works through a computer, which astronauts can use to call any number on Earth. Phones on the ground cannot call them back.

How do they Sleep on the Ship

Space has no "up" or "down," but it does have microgravity. As a result, astronauts are weightless and can sleep in any orientation. However, they have to attach themselves so they don't float around and bump into something. Space station crews usually sleep in sleeping bags located in small crew cabins.

Aurora Lights

Hello Bloggers, 

For inquiry, we have been learning about the southern and northern lights. Here is some information below. 

All religions have different about what causes the lights, the Chinese believe that it is the good and evil dragons fighting in the heavens etc. What actually causes it is that flares of the sun shoot at the Earth, but the Earth's molten core is pretty much a magnet so it fends it off but some get through and teams up with the oxygen and carbon atoms and creates the lights. Here is my artwork.

Also for inquiry, we have been creating some ironic artwork about a global issue. I chose racism. Here is a blurb below about racism and below is a picture of my art. 

I chose this because I really believe that we can all unite as one race if we aren’t the same colour skin. It is really unfair that black people get treated differently from white people.

The thing is though, what did the other colour race do to make them hate the other race, it is just very stupid. It just shows how messed up the world is.
