SCH 4U Final Lab Project

Final Project

draw a conclusion

Example: Small beads do lead to improved adherence.

conduct the experiment

Example:Conduct the experiment

design an experiment

Example: make small bead and make large beads. Adhere them to wood. Find a way to test the adherence

Make an hypothesis

Example: Smaller beads adhere better to wood.

Choose an answerable question

Example: Are smaller beads better at adhering to mulch?

Possible questions

Bead formation times

If we leave the solution for too long, is there a problem? I think some of the beads decay

bead size

will smaller beads work? Should we use bigger beads? How does hole size influence bead fomration?

CMC viscosity

Should we go more than 3%? Less than 3%

CMC agitating

Subtopic

CMC dissolving

colder is better?

does cold water really work better?

is disolving ewxothermic?

CMC sticking

CMC-H2O polymerizes when it is addded to water. We then add it to wood chips What leads to better adherence?

chips that we really saturated?

dry chips

wet chips
