Here's a step-by-step guide to help you get started:

Materials you'll need:

Styrofoam sheets or blocks
Cement or plaster
Acrylic paints
Paintbrushes
Small rocks and pebbles
Craft moss or artificial static grass
Twigs and scrubbing pads for the trees
Super glue, multi-purpose glue and Hot glue gun with glue sticks
Craft knife and heating tool (soldering iron)
Log house (Barbecue and popsicle sticks)
Miniature figurines (optional)
An aquarium or a clear container
Water (for the aquarium)
Aquarium gravel or sand (optional)

Steps to create the diorama:

Plan your design:

Decide on the layout of your diorama. Sketch out your ideas and consider the size and shape of the aquarium to ensure everything fits nicely.

Create the rock formation:

Cut the styrofoam into the desired shapes for your rock formation. You can create cliffs, caves, and other interesting rock features.
Use a craft knife and heating tool (soldering iron) to shape the styrofoam and create texture on the surface. Be careful with the knife and the heating tool to avoid accidents.
Mix your cement or plaster according to the instructions. Apply it to the styrofoam to create a rock-like texture. You can use a brush or your fingers to add texture and detail.
Let the cement/plaster dry completely. This may take several days or longer depending on the thickness of the applied cement.

Paint the rock formation:

Once the cement/plaster is dry, paint the rock formation with acrylic paints. Use earthy tones like browns, grays, and greens to create a realistic rock color.
Add highlights and shadows to make the rocks look more natural.

Add vegetation:

Use multi-purpose glue to attach craft moss, static grass and small bushes, and even some small rocks and trees to the diorama. Make it look lush and green.

Create the waterfalls:

You can use clear plastic or resin to create the waterfalls. Pour the clear material down the rock formation to create the cascading water effect. Let it dry.
If using an aquarium, you can also place a small water pump at the bottom and create a recirculating water system to simulate water flowing through the waterfall.

Build the log house:

Build the log house using barbecue / posicle sticks and super glue. Add some lighting for effects. Place the log house in a suitable spot on top of your diorama, preferably on a flat area.
Add other miniature elements like fences, animals, or people if desired.

Place the diorama on top of the aquarium:

Ensure that your diorama is stable on top of the aquarium. You may need to use wooden sticks or dowels to support it.

Add gravel and sand to the aquarium base and install lighting for effects:

If you'd like to create a more natural look, you can add a layer of aquarium gravel and sand to the base of the aquarium to give the appearance of the lake or riverbed.

Add water to the aquarium:

Fill the aquarium with water to the desired level. Be sure not to flood your diorama, but make sure the waterfalls and the base of the diorama are submerged.

Final touches:

Adjust the positioning of your diorama, ensuring that it looks visually appealing from all angles.
Turn on any water pumps or other features that you've added to create movement in the water.
Your styrofoam and cement diorama should now be complete, featuring a realistic rock formation, lush vegetation,
a log house, and even water elements with waterfalls.

Enjoy your creative display!
