Practical Work for Learning: Colour Vision
Read the Fine Print
Rating
0.0 stars
Overview:

This lesson is designed to exemplify a model-based inquiry approach to practical work. It is based around a model for human colour perception which describes colour-sensitive receptors (cones) in the retina. Students use their own ideas to make a prediction about the outcomes of an experiment to test colour vision. By gathering evidence of colour perception in the field of view, students build a model in the form of a map to help them understand what is happening on the retina. They then relate their map to the distribution of receptors (cones) in the retina, for different colours of light. They use the collected data to critique both their predicted model and the consensus model.

Practical Work for Learning: Combustion of Iron Wool
Read the Fine Print
Rating
0.0 stars
Overview:

This lesson is designed to exemplify a model-based inquiry approach to practical work. Iron wool is placed on a simple balance and set alight. Will it gain or lose mass? Students use their own ideas (mental models) to make predictions about the outcome of the experiment. They compare their predictions with their observations, and then use the consensus model to develop an explanation. In this case the consensus model is made up of the equation for the reaction, and particle theory.

Practical Work for Learning: Heart Rate, Breathing Rate and Physical Fitness
Read the Fine Print
Rating
0.0 stars
Overview:

This sequence of two lessons is designed to exemplify an argumentation approach to practical work, using an analysing and interpreting data framework. Students use primary data about heart rates and breathing rates, alongside secondary data from children and adults, to assess and argue for or against the validity of claims about physical fitness. They consider whether the evidence is sufficient in itself to support the claims, particularly when the sample size is small, or whether more data
is needed. They justify their decisions through argumentation.

Practical Work for Learning: Magnesium and Carbon Dioxide
Read the Fine Print
Rating
0.0 stars
Overview:

This lesson is designed to exemplify an argumentation approach to practical work, using a predict, observe, explain framework. When burning magnesium is placed into a gas jar of carbon dioxide it is not extinguished but burns more brightly. This is due to the relative positions of magnesium and carbon in the reactivity series. The result surprises many students who know that carbon dioxide puts out fires – and is in many fire extinguishers. This lesson allows students to argue about what they think will happen in the reaction and to draw up competing theories. They then observe the reaction and write an explanation for what they have seen.

Practical Work for Learning: Melting Ice

Rating
0.0 stars
Overview:

This lesson is designed to exemplify an argumentation approach to practical work, using a predict-observe-explain framework. Students often think that some materials are intrinsically warm (wood, plastic, wool) while others are intrinsically cold (metals, glass, water). This lesson challenges these ideas by presenting observations which many will find counter-intuitive. Through argumentation, students predict the outcome of an experiment, observe the result, and discuss how scientific ideas about energy transfer can explain what they see.

Overview:

This lesson is designed to exemplify a model-based inquiry approach to practical work in which students make, use and evaluate models for osmosis. Osmosis is an important process which allows plants to take up water. A model can be used to help explain how this process works, and to make predictions. In this lesson students make and use a 3-D model for osmosis and evaluate the 3-D model compared to a more familiar 2-D model for osmosis.

Practical Work for Learning: Putting Chemicals Into Groups

Rating
0.0 stars
Overview:

This lesson sequence is designed to exemplify an argumentation approach to practical work, using a classification framework. In these lessons students see for themselves that it is possible to group chemicals with similar properties – and that there are some chemicals which do not fit easily into a group. Students carry out a practical activity in one lesson and in the next try to group the chemicals according to the results of their investigations. At the end the students are told the four main groups that chemists use to classify chemicals and they try placing the chemicals they have been using into these groups.

Overview:

This lesson sequence is designed to exemplify a model-based inquiry approach to practical work in which students evaluate collision theory and rate equations as models for explaining rates of reactions. Understanding the rates of chemical reactions is important for controlling reactions in industry. In this lesson sequence students will evaluate collision theory as a model for predicting rates of reactions. They then collect data to determine the order of the reaction of calcium carbonate and hydrochloric acid, and deduce the rate equation. They use the rate equation to make predictions.

Rating
0.0 stars
Overview:

Students investigate which materials are good absorbers of sound and which are good reflectors of sound. This lesson sequence is designed to exemplify a careers-linked approach to practical work, using careers-related information to provide a context for practical work. There are many occupations in which people work with sound. For example, environmental officers may need to measure sound levels (or noise), and concert hall designers may need to control the absorption and reflection of sound.
