Exploration areas might be linked to an ongoing science topic or simply house intriguing things. For example, put out the following: kaleidoscope, binoculars, microscope, telescope, fly's eye lens, concave and convex lenses, a range of spectacles, periscope, plastic drinks bottle with coloured water, and colour paddles. Allow children to explore in pairs, so they talk about what they are doing. Place questions beside items to extend children's exploration and put materials in a box so they can make their own kaleidoscope or periscope.
If you really do not have space, then consider a "Science Exploration Box", with objects that children can take on to the carpet area or their table to explore.
