What effect does acid have on sea life?

This unit follows on from 'Do you like your oceans still or sparkling?' The activity demonstrates the ability of an acidic substance (in this case vinegar) to dissolve sea shells.

Malt vinegar contains acetic...

With this a-level video tutorial, the presenter talks about how we get the equation speed = distance / time and then looks at the differences between a distance / time and a speed / time graph.  It also demonstrates what the area under the graph represents as well as the gradient.  This can be followed by the...

Produced by the Learning and Skills Improvement Service, this activity takes students through a step-by-step approach to understanding the basic principles of distance-time and velocity-time graphs. Working through the activity will help students to:
* Understand the terms distance, time, velocity and...

This resource from Farming & Countryside Education (FACE) allows students to investigate how different farmers have addressed the challenge of sustainability, and the solutions they have devised to remain in business despite the serious long-term problems faced by the sector. The farm profiles help the students...

Produced by the Science Museum, this resource sees students working in groups to explore the issues surrounding genetic testing. Students receive a sealed secret box, that contains a chance card. Opening the box represents taking a genetic test. Students have to decide whether they would want to open the box. In...

A PISA in Focus study published in 2012 from the OECD (Organisation for Economic Co-operation and Development), looks at whether students perform better in science if they are encouraged to participate in extracurricular activities, such as field trips and science projects. Most countries (22 of 31 OECD countries)...
