If a government, organisation or individual scraps plans, it means the plans are cancelled.
For example:
The government scrapped plans to build a new airport. It was too expensive.
The company scrapped plans to open a new shop.
A scrapyard is a place where you take cars or metal that cannot be used. The scrapyard might sell the scrap metal so it can be recycled.
Also a scrap is a small piece of something. You might feed a dog scraps of food from your plate. You might use a scrap of paper to write a telephone number on.
Some people have scrapbooks. In these books they often put photographs or old newspaper articles in order to collect things about a person or event.
