| Experiment Number | Experiment Title | Action |
|---|---|---|
| 1 |
Density
Students prepare aqueous sugar solutions, measure mass and volume, calculate densities, then layer the solutions in a test tube.
|
|
| 2 |
Crystal Growth Part 2 (In Person)
Students select and suspend seed crystals in a previously prepared saturated alum solution, then actively monitor and maintain the growing single crystals.
|
|
| 3 |
Emission Spectra (In Person)
Students build a custom spectrometer using toiletpaper rolls, CD and black paper and use it to explore the composition of light sources.
|
|
| 4 |
Separation of Salt and Sand Mixture (In Person)
Students combine known amounts of salt and sand, then separate them using solubility in water, filtration, drying and evaporation. Recovery yields are calculated.
|
|
| 5 |
Extraction with Oil and Water (In Person)
Students mix herbs and spices with water or oil and using olfactory senses evaluate if the scented compounds are polar or non-polar.
|
|
| 6 |
Polymer and pH Indicator (In Person)
Students extract superabsorbent polymer from diapers and tests its absorbance. Additionally, the polymer is soaked in acid-base indicator and used to classify solutions as acidic or basic.
|
|
| 7 |
Decomposition (In Person)
Students heat sodium bicarbonate and observe its decomposition until the mass of the product remains constant. Percent yield of the reaction is calculated.
|
|
| 8 |
Gravimetric Analysis (In Person)
Students react crushed chalk with 1M HCl and precipitate the dissolved calcium ions using a sodium carbonate solution. The product of the precipitation is collected via filtration and calcium content of chalk is calculated.
|
|
| 9 |
Limiting Reactant (In Person)
Students react Alka-Seltzer tablets with water and vinegar mixtures of varying proportions and monitor the evolution of gas until the mass remains constant. The graphed and calculated data is used to explore the concept of limiting reactant.
|
|
| 10 |
Gas Laws with CO₂ and H₂ (In Person)
Students perform two gas forming reactions in closed systems: sodium bicarbonate and vinegar produces carbon dioxide, while magnesium and HCl generate hydrogen. Dalton\'s law, the ideal gas law and molar volume are explored.
|
|
| 11 |
Thermal Equilibrium (In Person)
Students combine water in a coffee-cup calorimeter with ice that is either melting or from the freezer, and monitor the temperature until thermal equilibrium is established. The enthalpy of fusion and specific heat of ice are calculated and compared to reported values.
