The Bartering System

  

Bartering

The Bartering system is extremely interesting. It means when you have something that another person wants and they have something that you want. When you are bartering it means that you both have something of equal value. For example, there is a baker who bakes delicious bread. But he needs some wheat to make the bread. He might go to somebody who grows wheat and trade two loaves of bread for 1 bunch of wheat. This is an equal trade. But one day the wheat grower might have a poor crop, so he might demand more bread. In the same way, the bread maker might have to close his shop due to losses so he might say he wants more wheat. This is the bartering system.

Analyse & Prediction Map - Making Slime

This is my Analyse and Prediction map that I made by our class experiment  - making slime. We used the ingredients and imagined what it would be like without the ingredients. Hope you enjoy!! :)

Define Change

Define change

I am unable to state anything relevant about change	I can state one relevant idea about change (I can list one part)	I can state several relevant ideas about change (I can list several parts)	I can explain the types of change and how they occur.	I can explain the types of change and how they occur. I can alter the variables and explain how this impacts a change.

Change Definition: Change is when something happens because of something else. Change means that you alter something to make it different. It can also mean changing your clothes. Change is when you make or become something different. A person can change to become a good friend or they can become a bad friend. This happens if they are not treated well or are sad because of something. They become better if they try hard to be a good friend and they are treated fairly. You can change to different colours to make a new colour by mixing them together. This can happen because when you mix a light and dark colour it makes a medium colour like violet or lime green.

Change is when something happens because of something else. You can change something physically and chemically. For example, when you change your clothes in the morning you are changing it physically because you are not actually changing the clothing or you. You’re placing something on to add a material. However, a chemical change is when you are changing something in a more experimental way. For example, when you’re baking a cake, the batter bakes in the oven to form foam-like bubbles. This is happening in a chemical way because you are changing the form it is in. If you replace the clothes with something else like hot oil or a hot fire spark your skin will burn and form a burnt mark on your body. This is changing the physical change to a chemical change. There are other ways to change things like cutting a cake, pouring food colouring in water, adding onions to sugar water. These are all physical changes. Chemical changes are things like, boiling an egg, burning yourself, melting a candle.  Anika

The first definition is when I didn't know much about change. The second is when I had learnt more about it and I knew more

Mouldy Bread Experiment - Analyse Map

This is our Mouldy Bread experiment that Advika, Yashvi and I did. This is an analyse map. I hope you enjoy it!!

Inquiry - A Roasted Broccoli Salad

This is my Can-Do kitchen science activity. To summarise, solids can change their shape but only some can go back to the way it was. The broccoli was delicious. So I learnt something good and ate something good. Anika
