To demonstrate the basic process of filtration used in separating insoluble solids from liquids, using a 3D working model that simulates real-life laboratory filtration.
Materials Required:
- Plastic funnel or paper cone (filter holder)
- Filter paper or tissue paper (filtration medium)
- Plastic/glass beaker or bottle (cut) – for collecting filtrate
- Muddy water (sand + water mixture for demonstration)
- Stand (cardboard or wire frame) to hold funnel
- Transparent pipe (optional) for visual setup
- Cardboard base for 3D layout
- Labels, paints, markers for presentation
How to Make – Step-by-Step:
- Prepare the Funnel Setup:
- Insert filter paper/tissue into a plastic funnel.
- Fix the funnel in a vertical position using a stand or cardboard holder.
- Create the Filtration Process:
- Pour muddy water into the funnel slowly.
- Water passes through the filter, and the sand remains above.
- Clear water collects in the beaker/bottle below.
- Label all parts: Funnel, Filter Paper, Impure Water, Clean Filtrate, Residue, Beaker.
- Make it 3D by using a cutout view showing water flowing down through layers.
Scientific Principle:
Filtration is a physical separation technique used to remove insoluble substances from liquids. It is commonly used in chemistry labs, water purification, and industry.
