To help students engage in science and mathematics through inquiry, PhET simulations were developed to allow students to investigate cause-and-effect relationships and answer scientific questions through exploration of the simulation.

Several tools in the simulations provide an interactive experience:

From the Association of the British Pharmaceutical Industry (ABPI), this interactive resource halps to answer questions that students have about the production of medicines and the careers available in the pharmaceutical industry.

There is a wide variety of questions on topics as varied as:

• The...

This Catalyst article introduces Henry Gosse, an expert naturalist. He devised an alternative explanation for the fossil record, but it failed to impress his peers.

This article is from Catalyst: Secondary Science Review 2016, Volume 27, Issue 1.

...

This Catalyst article explores whether the use of mobile phones increases the risk of cancer, including a recent study from Denmark which investigates the issue further.

This article is from Catalyst: Secondary Science Review 2011, Volume 22, Issue 2.

In this simulation students can see how light knocks electrons off a metal target, and recreate the experiment that spawned the field of quantum mechanics.

[b]Sample Learning Objectives include:[/b]

*Visualize and describe the photoelectric effect experiment.

*Predict the results of experiments...

This is a common investigation using a bulb and coloured filters to determine the value of Planck’s constant (h).  An oscilloscope is required and advice on the settings required are given.

This resource has been provided by Keith Gibbs.

The work suggested in this Nuffield Working with Science unit was intended to teach students how to process film and photographic paper at a relatively simple level, and to understand some of the principles behind the processes. Teacher were encouraged to make students...

This Catalyst article looks at the process of photosynthesis, by which plants make a range of biochemical compounds. The article explains how photosynthesis actually ties in with growth. Respiration is happening all the time in all cells in all living organisms. Taken on its own, photosynthesis adds materials to...

In this practical investigation, students measure the rate of photosynthesis in plants from different habitats (sun and shade), and then consider what this demonstrates about leaf adaptation.

When leaf discs are...

In this activity students create a graphical ready reckoner to assess physical fitness. The challenge is to construct the ready reckoner and ultimately use it in practical situations. Students are required to plot straight line graphs.

A multiple choice quiz on physical chemistry for A/AS level chemistry.

Although it is written for OCR AS/A level chemistry A and B (H032, H432,  H033, H433), it can be edited to suit your scheme of work.

From the Integrating Mathematical Problem Solving project by Mathematics for Education and Industry (MEI), this activity for post-16 students demonstrates that coffee cools gradually because it is hotter than room temperature and heat is lost to the room. Mixing the coffee with milk also cools it but this effect is...

From the Integrating Mathematical Problem Solving project by MEI, this series of activities explores how mechanical oscillations are important in many areas of everyday life. Sometimes they are useful, for example the motion of the suspension on a car, sometimes they...
