CO2 Levels Activity

This activity has been adapted from resources created for the Space Academy Applied Sciences KS3 masterclass. In this activity students investigate the CO2 concentration of three different samples and try to identify their source. The context of the experiment can be linked to either planetary/exoplanetary atmospheres, or to climate change.

Flying Teabag

Using energy transfer to make a teabag fly

January 30, 2013 | Posted in Educational Resources, Experiments | By

This quick and simple experiment demonstrates how energy transfer (convection) can be used to make a teabag fly. I have run this activity in school workshops with students KS1-KS5 (younger students requiring supervision throughout). This activity has also been run in a science festival environment during the 2013 BBC Star Gazing Live East Midlands Event and the Leicester NASA Apps Challenge. During a festival setting extra precautions must be taken as to where the stand is set up, to prevent encounters with drafts/air currents.

Spectroscopy Activities

January 20, 2013 | Posted in Educational Resources, Experiments | By

I have outlined 4 simple activities that can be used to demonstrate the principles of the electromagnetic spectrum and spectroscopy.  Applications can include environmental, Earth observation and spectroscopy on other planets! Separate instructions will be uploaded at a later date on how to create a Near Infra Red camera.
