=== 1. '''Elephant Toothpaste Explosion''' ===
* '''What it Teaches''': Exothermic reactions, catalysts, and decomposition of hydrogen peroxide.
* '''What You'll Need''':
** Hydrogen peroxide (6% or higher)
** Dish soap
** Food coloring
** Yeast mixed with warm water (as a catalyst)
* '''What to Do''': Mix hydrogen peroxide, dish soap, and food coloring in a bottle. Pour the yeast solution in and stand back as colorful foam shoots out like a volcanic eruption!
* '''Mess Level''': High (do it outside or on a tarp).
----
=== 2. '''DIY Slime Chemistry''' ===
* '''What it Teaches''': Polymers and chemical bonding.
* '''What You'll Need''':
** White glue
** Borax (or contact lens solution with boric acid)
** Water
** Food coloring and glitter for flair
* '''What to Do''': Mix glue, water, and food coloring. Gradually add the borax solution and knead until the slime forms. Encourage students to experiment with consistency.
* '''Mess Level''': Medium (sticky but manageable with table covers).
----
=== 3. '''Baking Soda and Vinegar Rockets''' ===
* '''What it Teaches''': Gas production, chemical reactions, and pressure.
* '''What You'll Need''':
** Small plastic film canisters (or similar containers)
** Baking soda
** Vinegar
** Tissue paper
* '''What to Do''': Wrap baking soda in tissue, put vinegar in the canister, and add the wrapped baking soda. Seal the canister, shake, and place it on the ground. Watch it pop!
* '''Mess Level''': High (do it outside).
----
=== 4. '''Colorful Milk Fireworks''' ===
* '''What it Teaches''': Surface tension and the behavior of molecules.
* '''What You'll Need''':
** Milk (whole works best)
** Food coloring
** Dish soap
** Cotton swabs
* '''What to Do''': Pour milk into a shallow dish, add drops of food coloring, and touch the surface with a cotton swab dipped in dish soap. The colors will explode and swirl.
* '''Mess Level''': Medium (contained, but food coloring can stain).
----
=== 5. '''Glow Stick Chemistry (Glow-in-the-Dark Fun)''' ===
* '''What it Teaches''': Chemiluminescence and energy release.
* '''What You'll Need''':
** Glow sticks
** Beakers with hot, cold, and room-temperature water
* '''What to Do''': Break and activate glow sticks, then place them in beakers of different temperatures. Discuss how temperature affects the speed of chemical reactions.
* '''Mess Level''': Low (but keep glowing liquid contained if sticks are cut open).
----
=== 1. '''Rainbow Density Tower''' ===
* '''What it Teaches''': Density and immiscible liquids.
* '''What You'll Need''':
** Honey, corn syrup, dish soap, water, rubbing alcohol, vegetable oil
** Food coloring
** Clear container
* '''What to Do''': Color each liquid and pour them one at a time into the container, layering them carefully to create a rainbow. Students can drop small objects in to test where they float or sink.
* '''Mess Level''': Medium (spills happen, but colors make it exciting!).
----
=== 2. '''Mentos and Soda Geyser''' ===
* '''What it Teaches''': Gas formation, nucleation, and pressure.
* '''What You'll Need''':
** Diet soda (2-liter bottle)
** Mentos
** Geyser tube (optional, for better aim)
* '''What to Do''': Drop Mentos into the soda as quickly as possible and watch the soda shoot into the air. Bonus: Set up different sodas to compare heights!
* '''Mess Level''': Extremely high (outdoor activity).
----
=== 3. '''Oobleck Madness''' ===
* '''What it Teaches''': Non-Newtonian fluids and states of matter.
* '''What You'll Need''':
** Cornstarch
** Water
** Food coloring
* '''What to Do''': Mix cornstarch and water until you get a gooey mixture that acts like a solid when struck but flows like a liquid when handled gently. Add food coloring for extra fun.
* '''Mess Level''': High (sticky, but totally worth it).
----
=== 4. '''Lava Lamp Chemistry''' ===
* '''What it Teaches''': Density, immiscible liquids, and gas production.
* '''What You'll Need''':
** Clear bottle
** Vegetable oil
** Water
** Food coloring
** Alka-Seltzer tablets
* '''What to Do''': Fill a bottle with oil and water, add a few drops of food coloring, then drop in pieces of Alka-Seltzer. The fizz creates mesmerizing bubbles.
* '''Mess Level''': Low to Medium (manageable but can be slippery).
----
=== 5. '''Flame Color Magic''' ===
* '''What it Teaches''': Emission spectra and chemical properties of elements.
* '''What You'll Need''':
** Cotton swabs
** Salt, borax, copper sulfate (or other salts)
** Rubbing alcohol
** Metal tray or fire-safe dish
* '''What to Do''': Dip swabs in rubbing alcohol mixed with salts, light them in a controlled flame, and watch the flames change colors. (Safety goggles and a controlled environment are a must!)
* '''Mess Level''': Medium to High (fire and alcohol can be messy but thrilling).
=== 1. '''Vinegar and Baking Soda Volcano''' ===
* '''What it Teaches''': Acid-base reactions and gas production.
* '''What You'll Need''':
** Baking soda
** Vinegar
** Dish soap (optional for foam)
** Food coloring
** Paper mache or sand to make a volcano
* '''What to Do''': Build a small volcano structure. Inside, mix baking soda, a bit of dish soap, and food coloring. Pour vinegar in, and watch the eruption!
* '''Mess Level''': High (great for outdoors or on a tarp).
----
=== 2. '''Carbon Snake (Sugar and Baking Soda Reaction)''' ===
* '''What it Teaches''': Combustion and thermal decomposition.
* '''What You'll Need''':
** Sand
** Sugar
** Baking soda
** Rubbing alcohol
** Lighter
* '''What to Do''': Mix sugar and baking soda, place on a mound of sand, and pour rubbing alcohol over it. Light the alcohol, and watch a black "snake" grow out of the sand.
* '''Mess Level''': High (do it outside or in a well-ventilated area with safety measures).
----
=== 3. '''Instant Hot Ice''' ===
* '''What it Teaches''': Crystallization and supercooling.
* '''What You'll Need''':
** Sodium acetate (can be made by reacting vinegar and baking soda)
** A glass container
** Hot water
* '''What to Do''': Supercool a sodium acetate solution, then pour it out or touch it with a seed crystal to instantly form solid "ice" that generates heat. Let students shape it as it crystallizes.
* '''Mess Level''': Medium (contains spills but is relatively easy to clean).
----
=== 4. '''Rainbow Fireworks in a Jar''' ===
* '''What it Teaches''': Solubility and molecular interactions.
* '''What You'll Need''':
** A clear jar
** Warm water
** Oil
** Food coloring
* '''What to Do''': Mix food coloring with oil in a cup. Slowly pour this mixture into a jar of warm water. The food coloring will streak and "explode" as it mixes with the water, creating a firework effect.
