One of the strategies in terms of exhibit development is leveraging the history to support the science, and science to back up the history. This helps create an environment which is multi-layered, and connection-rich (not to mention a nice match with current educational standards).
At the same time, science and scientific phenomena can provide a level of impact and wonder that history can't. The vehicles in science museums tend to be more hands-on. So we're using the engaging tools of science exhibits to provide attractors to both topics.
The other is by highlighting role models of all ages, shapes, sizes and abilities. This brings a first-person voice to the multitude on the museum floor- it personalizes the experience. It also can have the affect of making seemingly out of reach achievements seem more... acheivable for the average Jill.
