FRAN SCOTT demos & pracs Bang Goes the Theory - Hands-on science: Water bottle rockets Wetsuits for Paratriathletes Sep 12, 2013 Triathlon is an event that requires competitors to complete a three-stage race of swimming, cycling and running. Triathletes wear special wetsuits for the swim which are then removed before the cycling and running stages. Whilst still providing warmth and buoyancy, these wetsuits are designed slightly differently to the ones surfers might wear. They can be thinner and smoother to make them go faster through the water and they are easier to take off (the race does not stop between stages so it is really important to be able to take the wetsuit off quickly). Triathlon wetsuits are, of course, expertly designed – but they are designed for able-bodied athletes. Your challenge is to design a new wetsuit for a paratriathlete. Students should work in teams of 4-6 and the STEM Challenge is designed to take approximately 6-8 school weeks. Further guidance on how to approach the Challenge can be found on the Guidance page. This STEM Challenge Resource Pack includes:
5 Fun Science Experiments for Kids Everyone knows science is awesome, but did you know you can do science right in your own kitchen? Ok, maybe you did, but if you're not sure where to start, we've got five really fun experiments that demonstrate the scientific principles of buoyancy, surface tension, density, chemical reaction and non-Newtonian fluid. Best of all, families can do these easy experiments with common, household items. Sesame Street's fuzzy, blue scientist Grover stopped by the #5facts studio to teach us a few things about the scientific method. Looking for more amazing experiments families can do together? Be sure to tweet your discoveries with the hashing #5facts, and subscribe to our YouTube channel for more fun trivia about science, history and pop culture. 1. This experiment is a great way to explain the principle of buoyancy and also to get your kids to voluntarily wash your fruit. What you'll need: Regular orangePeeled orangeDeep bowl or pitcher of water One of these oranges will sink and one will float.

Reeko's Mad Scientist Lab science for hobbyist, students, and teachers of all ages. Q: How much water do you put in a water rocket? A: The simple answer is something less than half full. Since the compressed air stores the energy, and the water provides momentum, both are needed. Fill perhaps 40-50% of the motor volume with water. We call this the Load Fraction. The longer answer is, it depends. The following factors effect how much water is optimal: Empty weight of the rocket, cross-sectional area (or diameter) of the rocket, nozzle diameter, operating pressure, and drag coefficient. So how do I determine the optimal load fraction? By conducting experiments, we are rocket scientists after all! Is there another way? Yes, conduct your experiments using a water-rocket simulator like our java-based applet. (back)
-BSI The Secret Life of Snot - British Society for Immunology Snot, what's it all about? Here at the BSI, we're inquisitive people so we set about finding out more about those disgusting things called bogies. The result was our stand 'The Secret Life of Snot' at The Big Bang Fair 2011 which took place at the ExCeL Centre, London from the 10-12 March. You can see photos of the stand and our activities at The Big Bang Fair here. For those of you that weren't able to make it, we’ve put our findings here, along with our snot recipe. Why do we make it? How does our body make something that is quite so disgusting and gloopy? The remaining proteins in mucus give it a protective function, these include: antibodies – these tiny proteins produced by B cells, activate the immune system alerting it to the presence of foreign objects such as dust and germs lysozyme – an enzyme that chops up bacteria What about the colour? Back to top Gruesome Snot Recipe You need: Making your own snot: 2)Using a paint brush or dropper add a very small amount of food colouring. 4)Enjoy!
