This Connected Learning Experience looks at chemical reaction rates.

The resource is a Science ASSIST Connected Learning Experience to assist Year 10 teachers teach the concept of reaction rates to their students.

Description: In this investigation, factors which affect reaction rates are investigated by conducting experiments. Students can then use their knowledge and understanding of reaction rates to take on the role of a process chemist charged with controlling the time taken for a specific reaction to take place.

Learning intentions

Students will be able to:

• observe and understand that chemical reactions take place at different rates;
• identify factors which can affect reaction rates;
• explain the effect of surface area, concentration and temperature on reaction rate;
• plan appropriate investigation methods to manipulate the rate of a chemical reaction, taking account of fair testing;
• make careful and accurate observations;
• make predictions based on scientific understanding;
• construct graphical representations of data and use these to determine relationships between variables; and
• construct conclusions based on evidence.
