                                                                            Lab Ice cream
Today we do a Ice cream lab and learn an ice cream.why do we add salt to the ice? We add salt because  Salting icy roads and walkways lower the freezing point of the water that forms ice which leads to melting and prevents falling snow or rain from being able to freeze. Though salt can be effective, it does have some negative impacts on the environment.why do we add the cookies and other things, only after the milk has frozen slightly the topping is not frozen.what are two factors that affect the freezing you think? - When we shake the ice and scrape the ice bag to make the ingredients freeze.
- Furthermore salt and sugar may affect the factors of freezing.
 4)  Why do you need a bit of air in the bag?
- We need to make the ice freeze fast, therefore we need a bit of air to make it easier to freeze.

The impact of environment on society
The trees help the earth to give oxygen to earth and not have the earth is very hot ,but people still cut the trees
People hunt the animal and the animal will die.
They destroy coral in the ocean so  it effects sea animal.
Travelling by plane, it happens CFC in the air. The world will be global warming


-Acid rain is produced by factory processing.

writing assessment

Blog writing assessment
Last year I know about organisms and freshwater and adaptations and where 
 animals live and we know about acid rain and atmosphere and I felt good but Grade is not good and this term I want to improve my Grade  and I want to know about Science more that I know and this term I know more about speed and atmosphere 
and this term I felt feel neutral and next year I will study harder about science.

Acid rain

 is caused by a chemical like sulfur dioxide and nitrogen oxides are released into the air. where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.Acid rain has many ecological effects.Acid rain makes waters acidic.Because nitrogen oxides are created in the processsome power plants are changing the way



Global warming
Most climate scientists agree the main cause of the current global warming 
trend is human expansion of the "greenhouse The effects of global warming are the environmental and social changesGlobal warming 'cure' found by scientists
