Several of my readers seem to be teaching children science and mathematics at home. For their benefit, here is a list of resources, which I will keep updating.

Posters
For people with children, these high-resolution posters are intended for printing on A3 paper, and can be freely downloaded:



Biology posters: Ladybirds of Australia, Plants and Fungi, Some Flowering Plants (monocots marked with a dot)



Astronomy/geography posters: Southern Cross (showing colours and magnitudes of stars), Orion (ditto), Geographical Features
Nature study – Websites
- John Muir Laws, nature artist
- CNPS Nature Journaling curriculum
- Nature Study Australia
- Ultimate Guide to Nature Study
- My post on phenology wheels
Nature study – Dioramas
These cut-out dioramas are intended for displaying plastic animals, and for a discussion of animal habitats (click for hi-res images). There is also an Australian scene and a pond scene.
Space-related and other scientific paper models
Other cut-out dioramas here include a chemistry laboratory, the interior of the Space Station, the surface of Mars, and “Earthrise” on the Moon. Related paper models on the web include:
- These space-probe models, including a detailed model of Pioneer 10
- These space-probe models from the ESA
- These models of the New Horizons probe to Pluto
- This or this website for producing sundials tailored to your location
- This website for producing an astrolabe tailored to your location
Solar System scale model
The following images of the eight major planets and Pluto are to scale, with each image 500,000 km in width (the third image also includes the Moon). For comparison, the diameter of the Sun is 1,390,000 km, so you can team these planets up with a big yellow circle which is 2.8 times the width of each image. Click on the images to zoom.
If you want distances from the Sun to each planet to be to scale as well (like this or this), they are shown below (in millions of km and multiples of the width of each image). If the images above are printed out 5 cm or 2 inches wide (i.e. at a scale of 1 cm = 100,000 km), then the sun would be 14 cm (5.5 inches) wide, and distances from the Sun to each planet would be as per the bottom two rows of the table.
58 | 108 | 150 | 228 | 779 | 1,434 | 2,872 | 4,495 | 5,906 | million km |
120 | 220 | 300 | 460 | 1,560 | 2,870 | 5,700 | 9,000 | 11,800 | multiples |
6 | 11 | 15 | 23 | 78 | 140 | 290 | 450 | 590 | metres |
19 | 35 | 49 | 75 | 260 | 470 | 940 | 1470 | 1940 | feet |
This image shows the complete solar system, but most planets are too small to see.
Mathematics – Paper models of polyhedra
- There is a wide range of cut-out paper models at www.korthalsaltes.com
Mathematics – Fun with Möbius strips
- www.wikihow.com has good instructions on colouring and cutting a Möbius strip
Mathematics – Fun with tessellations
- The tesselation above left, inspired by M.C. Escher, is assembled from the lizard above right, taken from seanmichaelragan.com (click on images to zoom)
- tessellations.org gives several methods for creating cool tessellation patterns, in the same spirit
- exploratorium.edu gives a simpler approach to tessellation patterns
Chemistry – Up-to-date periodic table
Clck to zoom the periodic table. For more on the elements, see:
- The fantastic book The Elements by Theodore Gray
- The associated boxed set of elements cards
Science – Home experiments
- learn.genetics.utah.edu shows how to extract DNA from plant cells
- www.wikihow.com, www.instructables.com, and www.wired.com show how to build an electric motor
- www.instructables.com and en.wikibooks.org show how to make a lemon battery like the one pictured above
