Litmus Paper

 Today in science we are looking at litmus paper.

Litmus is a tree lichen fungi and is made into small paper strips or a liquid for testing acids or alkalines.

1. Blue litmus paper determines if something is acidic. It turns red in solutions with a pH less than 7.

2. Red litmus paper determines if something is alkaline. It turns blue in solutions with a pH greater than 7.

Litmus experiment:

Materials:
1. Red litmus paper
2. Blue litmus paper
3. Sodium hydroxide
4. Hydrochloric acid
5. pipette
6. 4 test tubes

Steps:
1. Rip the litmus paper in half and put half in each test tube.
2. Add 3 drops of hydrochloric acid to the red litmus paper in test tube 1.
3. Add 3 drops of hydrochloric acid in the blue litmus paper in test tube 2.
4. Add 3 drops of sodium hydroxide to the blue litmus paper in test tube 3.
5. Add 3 drops of sodium hydroxide to the red litmus paper in test tube 4.

Findings:

The blue litmus paper with hydrochloric acid went red
The red litmus paper with hydrochloric acid went didn't change
The red litmus paper with sodium hydroxide went blue. The water went yellow
The blue litmus paper with sodium hydroxide went didn't change.

Conclusion:
Blue litmus is an acidic
red litmus is alkaline.

Dogs - Puppies

 For the past 2 and a half weeks, Me and my family have been looking after 7 puppies. The reason why we are looking after 7 puppies is because my 2 dogs had them. My dogs are chocolate labradors. One of my dogs is skinny, very tall and dopey. My other dog is big and small but fast. Since the puppies are 2 and a half weeks old they are starting to walk and most of them have their eyes open wide. All of the puppies are chocolate. There are 2 runts out of all of them. Here is a photo of the puppies.

Parihaka

 Yesterday in Nga Tangata we started looking at Parihaka. We had to read 3 articles about Parihaka. We had to make a copy of a slideshow and do our work on there. Here is my work.

Science - Acids and Bases

 Today in Science we are looking at acids and bases. 

What makes something acid?
An acid contains Hydrogen atoms that break off to react with a substance.

What are 3 examples/names of acids:
Hydrochloric Acid
Sulfuric Acid
Nitric Acid
Citric Acid
Acetic Acid
Formic Acid
Carbonic Acid

What is an acid?

An acid (HA) is a solution that breaks into H+ and A-

Aim: To make red cabbage pH indicator for use on different household chemicals


Red Cabbage indicator

Materials:
1. Red cabbage
2. Beaker
3. Bunsen Burner
4. Pipette
5. Sodium Hydroxide
6. Test tubes
7. Paper towels
8. Test tube rack
9. water
10. Hydrochloric acid

Steps:
1. Chop up the cabbage into small pieces. Place beaker and cover 
2. Bring the solution to boil using a bunsen burner and then turn the heat off. Let it sit to cool down.
3. Pour cabbage water through a paper towel into a beaker. The dark purple liquid in the jar is the pH indicator liquid.
4. Suck up the indicator into a pipette
5. Use the cabbage indicator and the pH chart below to test the acidity of the different 3 household liquids plus the hydrochloric acid and ammonium hydroxide.

Te Wiki O Te Reo Maori

 Today in Tuhura we are doing cybersmart. For cybersmart we are celebrating Maori language week. We had to go onto a site. On that site we have to sign up for the movement. After we sign up we have to make a DLO about Te Wiki o Te Reo Maori. I did the DLO on canva. Here is the DLO. 

Science - Sherbet

 Today in science we are looking at baking soda. We are also looking at sherbet.

My 10 points for baking soda:
10. Srub away marks on your wall
9. Using it as deodorant
8. Cleans your sink and gets rid of the smell
7. Cleans your grout lines (in between your tiles)
6. Makes a better cleaning product
5. Helps kitty litter
4. Oven cleaner
3. Wash build-up from your hair
2. Make a deodorant for your carpet
1. Its a good laundry booster

Recipe:

1 tsp of powdered drink crystals (eg Raro)

1/4 tsp citric acid 

1/4 tsp baking soda

1/2 tsp icing sugar

Put all ingredients into a ziplock bag,  stir, and enjoy.

Materials:

1. Citric acid
2. Baking soda
4. Raro
5. Teaspoons 
6. Cup

Steps:

1. Get your cup
2. Put the raro into your cup
3. Get a 1/4 of a tsp of baking soda and put it in your cup
4. Put a 1/4 of a tsp of citric acid into your cup
5. Mix and enjoy

Findings:

How does sherbet react when you put it in your mouth? The sherbet dissolves. 

What ingredient in the sherbet is tingly in your mouth? The ingredient in the sherbet that is tingly is baking soda.

Conclusion:
Make sure to do the measurements properly or it will taste bad. baking soda has lots of different uses.

Reading - MeMe & Me

Today in Wga we have time to do work that we did earlier in the week. The work I am doing is hurumanu. I read a story called MeMe & Me. In the story, the girl begged her parents for a phone and also did cleaning at her nan's house to get money. The girl's name is Nina. We have to answer some questions from the story.

The main points of the story are Nina gets a phone, she gets a friend called MeMe. MeMe is very rude to her. At the end, Nina gets trapped in the phone and MeMe is now in her body. MeMe looks like Nina.

MeMe is a person on the phone who looks like Nina. MeMe is a person who is friends with Nina. We think MeMe is a robot. 

There is a possibility that this can happen in real life but I don't think it will. The reason why I think at it will not happen in real life is because there is lots of things that are like this already. 

I don't know what the author is trying to tell us.
