Project: How to construct a wood retort stand.

Constructing a basic wood retort stand involves a few simple steps. Here's a general guide:

Materials:

  1. Wooden dowel or rod (for the vertical support)
  2. Wooden baseboard
  3. Wooden blocks or pieces (for clamps)
  4. Screws
  5. Saw
  6. Screwdriver or drill
  7. Sandpaper (optional)

Steps:

  1. Prepare the Materials: Measure and cut the wooden dowel to the desired height for the vertical support.
  2. Assembly of Vertical Support: Find the center of the baseboard and attach the wooden dowel vertically to it. This will be your central support.
  3. Attach Wooden Blocks for Clamps: Attach wooden blocks or pieces horizontally on the wooden dowel at different heights to serve as clamps. These can be adjusted to hold various apparatus.
  4. Secure the Joints: Ensure all joints are secure by using screws. Pre-drill holes to prevent the wood from splitting.
  5. Stability Check: Make sure the retort stand is stable by placing it on a flat surface. Adjust the base or trim the dowel if needed.
  6. Optional Finishing Touch: Sand the wood to smooth any rough edges.

NOTE: This wooden retort stand may not be as durable or versatile as metal ones, but it can work well for light laboratory setups. Ensure that it meets your specific needs and safety considerations for your experiments.

EVALUATION:   Discuss briefly, heat of neutralization.

Write down five (5) equations that support heat of neutralization.

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the students positively
