tasting

 today we learned about taste and how it works.

first i will tell you four different tastes

sweet: candy,apples,banana

sour: tamarind,lemon,lime

bitter;grape fruit,dark chocolate,black pepper

salty: pretzels ,fries ,meat

experiment: blind taste testing

equipment

1.samples 1-9

2.blindfold glasses

3.recording chart

4. ice cream stick taster

method

1. get safety glasses and make a blindfold.

2.set up your chart and make sure that the person you are working with knows where to record your responses.

3.using an ice-cream stick you will dip it into the sample.One the sample is on the stick you will taste it and tell your partner your response.

4.there will be 2 answers

5.at taste test one you need to hold your nose

answer 1. is it sweet, sour, salty, bitter. record it.

answer 2. what do you think it is. record it.

6.repeat this for the next samples but you will only need to use your ice-cream stick taster for samples 1-4.

Sherbet

In science we are making some sherbet.

baking soda also known as Sodium Bicarbonate is a base it has many uses such as:

1.baking

2.wash build up out of your hair

3.medicine

4.scrub away marks on walls

5.underarm deodorant 

6.clean and unclog smelly sinks

7.clean your tiles and grouts

8. deodorise your kittens litter

9. clean your oven

10. deodorise your carpets

equipment:

cup

ice cream stick for mixing

raro or jelly crystals

icing sugar

citric acid

baking soda

teaspoon or quarter teaspoon

recipe:

1 teaspoon of powdered drink crystal

1/4 teaspoon of Citric acid

1 teaspoon of icing sugar

 1/4 teaspoon baking soda

1.citric acid and baking soda are involved in the reaction

2. icing sugar and raro was not involved in the chemical reaction

4.citric acid

5.baking soda

Neutralised

today we are testing acids again.

equipment

pipettes

test tube

test tube racks

boiling tubes

water

steps

1.Take a test tube rack with 1 boiling tube at each end of the rack and 4 test tube

2.half/quarter fill the boiling tube at one end with sodium hydroxide

3.half/quarter fill the boiling tube at one end with hydrochloric acid

4.fill each test tube with 5 drops of Universal indicator

5.Using the pipettes you will add drops of the acid or alkaline to the test tube to make colours of red,orange,yellow,green,blue,violet

6.don't mix the pipettes

science-change

today in science we got a empty bottle a cork some vinegar and baking soda first we got the bottle and then we put the vinegar and then we took 2 teaspoons and then we put on the cork very fast because  the gas rise very fast then the cork pop out of the bottle and then the gas escape the bottle and got out of the bottle so it had more space to move and then we will do it again but outside.

Fizz,Pop,Froth

In Science we are learning about. Change happens when we mix or combine two different reactants substance together. When this happens a chemical reaction takes place today.

science

I am starting to learn about science and change. This is what I found out today. What new information can someone tell me?
