Welcome to the Core Scientific Mathematics section of stemNRICH - Core. This contains a set of activities designed to develop the basic applied mathematical skills needed to make the most of the study of a science in the final years of school or university.
| For more advanced mathematical problems please see the Advanced Scientific Mathematics section. For advanced activities more directly based around specific mathematical applications, please see bioNRICH , chemNRICH , physNRICH or engNRICH | ||||

- | Constantly Changing | Many physical constants are only known to a certain accuracy. Explore the numerical error bounds in the mass of water and its constituents. | |
Image
|
YES | Peaches Today, Peaches Tomorrow | A little monkey had 60 peaches. On the first day he kept 3/4 of his peaches, gave the rest away and then ate one. On the second day he kept 7/11 .... How many did he have left at the end? | |

YES | Real-life Equations | Relate these commonly used equations to points on a series of graphs. Which are possible and which are not? | |
Image
|
YES | Equation Matcher | A series of graphs are given containing just 2 or 3 points. Which equations do the points rule out? | |
Image
|
YES | Maths Filler | Can you work out how to make height-time charts as these unusually shaped vessels are filled up? | |

|
- | Global Warming | How much energy has gone into warming up the planet? | |
Image
Image
|
YES | Carbon Footprints | Is it really greener to go on the bus, or to buy locally produced food? | |

|
YES | A Question of Scale | This interactive page allows you to test your knowledge and skill using powers of 10 to place physical quantities in order of size. |
Image
|
YES | Power Countdown | Try to hit the targets using the operations of powers and roots. | |
| Data handling | Image
|
YES | Data Matching | Use your skill and judgement to match the sets of random data |
Image
|
YES | Back Fitter | 10 graphs are of noisy experimental data are given. Can you use the spreadsheet provided to find algebraic graphs which match them closely? | |
Image
|
YES | Who's the best? | Which countries have the most naturally athletic populations? | |
Image
|
YES | David and Goliath | It is suggested that heavier competitors are at an advantage in the shot put. Do the data support that claim? | |
Image
|
YES | Guessing the graph | Analyses these pieces of scientifc data and try to deduce the equation of the curve underlying the process. | |
| Trigonometry | Image
|
- | Far Horizon | An observer is on top of a lighthouse. How far from the foot of the lighthouse is the horizon that the observer can see? |
Image
|
YES | Perfect Eclipse | Find out why perfect eclipses are, in fact, perfect. | |
| Units | Image
|
YES | Uniform Units | Can you choose your units so that a cube has the same numerical value for it volume, surface area and total edge length? |
Image
|
- | Bigger or Smaller? | Develop your intuition for changing units by asking the simple question: will a unit change give me a larger or smaller number? | |
