2.1 Equipment List
- Ice Cream Stick
- Heating plate
- UHU glue
2.2 Diagrams of experimental setup
- Measure 15ml of UHU glue
- Place the glue in a beaker
- Heat the glue to desired temperature using heating plate(to obtain higher temperatures)
Cool the glue to desired temperature using a fridge ( to obtain lower temperatures)
- Apply glue to smooth side surface of wood with a brush
- Attach wood with glue to another piece of wood
- Leave to dry for 45 seconds
- Place the setup on supports
- Place increasing weights on the joining part until it breaks
2.4 Risk Assessment and Management
We may burn ourselves while handling the hot glue.
Students must wear gloves when carrying out the experiment and handle the Bunsen burner setup with care.
As the experiments involve heating, there is a risk of fire if the flame accidentally touches any flammable material.
Make sure that there are no flammable materials near the heating apparatus and be careful around the Bunsen burner.
We might injure ourselves while handling the weights.
Handle the weights with care.
As the experiment involves glassware, there is a risk of breakage and cutting of the hands.
Wear gloves when carrying out the experiment. In case of breakage, cuts to the hands will be minimized.
2.5 Data Analysis
- Tabulate data in table. Take 2 readings of the amount of mass needed for the wood to bend enough to touch the surface of the table.
- Plot a graph that shows the relationship between the temperature of glue and the Amount of mass needed for the wood to bend enough to touch the surface of the table.
- Analyse the data and come up with a solution.
The results will be taken in a table that looks like this:
Amount of mass needed for the wood to bend enough to touch the ground
Temperature of glue upon application (in degrees celsius)
The cartesian plate and the labels of the graph will look like this:
