Framework Activities
Chemistry Frameworks for Activities provide a list of investigations for a number of different areas of the Junior Chemistry syllabus such as Hardness of Water, Investigating Air, and Conductivity. Each experiment is accompanied by a PDF Document which outlines the learning outcomes of the investigation.
- Framework C12: Investigating Water Treatment OC33
In this activity you will explore the stages in water treatment, build a device to filter the water samples and identify different materials used for filtration.
- FrameworkC11: Investigating Hardness in Water OC30, OC31
In this activity you will design an investigation to test for water hardness. Making sure to be aware on how to keep the investigation fair and also be aware of safety issues during the investigation. Record the data and classify hard and soft water. Explain and interpret your results.
- Framework C10: Investigating the Separation of Mixtures OC2
In this activity you will design, prepare and set up an investigation to complete the task. Select and use a variety of equipment in the process. Record data, compare results with your prediction and analyze your results.
- Framework C9: Investigating air OC21, OC22
In this activity you will develop an experiment to show that Oxygen is a component of air and how much Oxygen is in air. You will have to predict and examine the results, and find out why the results may be different from the prediction. Also, you will have to identify safety issues.
- Framework C8: Investigating the effectiveness of antacid tablets OC36
In this activity you will assemble a pH sensor with the aid of a computer. Calibrate the sensor and use data-logging software to record data on table and graph.
- Framework C7: Investigating solubility and temperature OC15
In this activity you will carry out an investigation following a correct scientific approach. Be able to explain the x and y axes of their graph. Be able to examine and give an explanation of the values in the results table and then be able to interpret the curve correlate with the curve plotted. Identify variables, only changing one at a time and identify the need for a fair test
- Framework C6: Investigating evaporation and cooling OP28
In this activity you will describe how to make temperature measurements and get a time graph using a temperature sensor and a data logger. You will also have to identify safety issues, a fair comparison, the fixed variables, the variables that change and the sources of error.
- Framework C5: Investigating the reactivity of metals OC52
In this activity you will place pieces of calcium, magnesium zinc and copper into water and observe how reactive each element is in water. Place pieces of calcium, magnesium zinc and copper into dilute hydrochloric acid and observe how reactive each element is in dilute hydrochloric acid.
- Framework C4: Investigating the titration of HCI against NaOH OC 38
In this activity you will identify burettes and pipettes and state their functions. You will also have to identify the change in pH as the base is added to an acid. Recognize that neutralization is occurring as a result of changing pH. Determine the point of neutralization, predict the effect of dilution on pH and compare the graphs produced for the different concentrations of acid.
- Framework C3: Investigating the combustion of fuels and the effects of acid rain OC55
In this activity you will plan and design an investigation where you change only one variable.
- Framework C2: Investigating conductivity OC 44
In this activity you will be using a conductivity probe in various solutions with the data-logger. You will also use appropriate software to show the results in the form of a bar chart or graph.
- Framework C1: Investigating Rusting OC45, OC46, OC47
In this activity you will investigate placing an oxygen sensor in the flask with damp steel wool and record oxygen levels for 10 minutes. Repeat with dry steel wool.
