Answer (1)
20 examples of soluble and insoluble substances, suitable for a 6th-grade science level:Soluble (Dissolves in Water): * Table salt (sodium chloride) * Sugar (sucrose) * Instant coffee powder * Tea powder (the soluble parts) * Lemon juice concentrate (the solid part dissolves) * Honey * Baking soda (sodium bicarbonate) - has limited solubility but does dissolve noticeably * Epsom salt (magnesium sulfate) * Food coloring (most types) * Vinegar (acetic acid in water) - the acetic acid is soluble * Washing soda (sodium carbonate) * Borax (sodium tetraborate) * Citric acid powder * Some powdered drink mixes (like lemonade or juice powder) * Soluble fertilizers * Alum (potassium aluminum sulfate) * Mouthwash (the active ingredients dissolve in the liquid base) * Some types of glue (water-based) before they dry * Isopropyl alcohol (rubbing alcohol) * Certain medications in powder or liquid formInsoluble (Does Not Dissolve Well in Water): * Sand * Gravel * Clay * Cooking oil (like vegetable oil or olive oil) * Butter or margarine (forms droplets but doesn't truly dissolve) * Wax (like from a candle) * Plastic pieces * Wood shavings * Iron filings * Chalk dust * Flour * Cornstarch * Pepper (ground) * Sawdust * Styrofoam * Gold or silver (pure metals) * Sulfur powder * Talcum powder * Nail polish * Crayons (the waxy part)I hope these examples are helpful for your science class!
