It depends on how ready we are as teachers to go on and work on a curriculum proposed by our kids inspired by a museum. 

The general theme can be proposed through our choice of museum, for example, ''natural history museum'' and let the kids choose the specific theme/category, for example, ''insects''

Apart from the theme and the curriculum, there are secseve practical things we as teachers have to do beforehand. Visit the museum, learn about fees and transport, one month in advance propose  the visit to the school director; argument the reasons why you wanna take your class to the museum, present the fees, dates and transport. When you have the ok think about the pedagogical objectives and plan your month  

I chose 10 sculptures and brought with me objects. Each sculpture became an inspiration for exploration.

Some sculptures looked like bended wire, so I brought wire and after deicovering the sculpture with the kids I gave them the wire. They alla started bending the wire and some of them tried to copy picasso's sculpture. 

Another one looked like cut paper so I gave the paper and scissors. 

Children are learning by experience. Giving them the materials and the inspiration, listening to their comments and discussions is a great way to start and facilitate the museum experience. Trigger their curiosity, open the domaine of experiences and engage children to the learning process.

''First I start with sheets of paper'' Picasso

After a visit in the Picasso sculptures exhibition. Picasso said ''first I start with sheets of paper'' and the he continued with the other materials. So I created a series of ateliers where the kids would start with the idea of a paper sculpture, then try to represent the same sculpture using clay, then using wire etc..
