Guides to Assessment in Education: Mathematics
Teachers make assessments all the time for a whole variety of reasons. Assessment is essential to teaching. It has to be acknowledged that although getting to know students thoroughly is part of a teacher's expected load, assessment does represent a noticeable burden. Above all, the report tries to emphasize assessment as a…
Adaptations to Arid Climates (Age 11-14)
In this ARKive resource, students learn about how different animals and plants are adapted to surviving in arid habitats. Working in groups, students design and carry out an experiment aimed at testing the effectiveness of different adaptations in reducing water loss. Using a worksheet as guidance, students also compare species…
Invasive Species (Age 11-14)
This resource from Arkive allows students to investigate the impacts that invasive species have on the environment, the effects that they have on native species and habitats, and the characteristics that make certain species good invaders. The activity looks at the different ways in which invasive species can potentially be controlled…
Handling Data: African Animal Maths (Age 7-11)
This resource from ARKive, aimed at Key Stage Two, focuses on handling data, using some of the species that inhabit the African savannah as a context. It involves completing a table on the height and weight of animals and converting heights from metres into centimetres. In a second activity children are asked to interpret the…
Model Cells
The cell is the smallest unit of life and for many millennia single celled organisms were the only form of life on Earth. It’s this type of life that astrobiologists are looking for elsewhere in the solar system. In this activity, wallpaper paste is used to build model cells Curriculum areas covered: • Cell biology • Cell…
Martian Death Rays
Could there be life on Mars? Perhaps so, although the high intensity of UV light means that it is unlikely to be found on the surface. The experiment demonstrates how bacteria grown on agar plates can be killed off by UV exposure. Curriculum areas covered: • Microbiology • Cell biology • Aseptic technique The…
What's Your Limit?
Conditions on other planets are unlikely to be within the same ranges as that experienced by Earth. However, a degree of variance from ‘ideal’ ranges may be tolerable for a small number of organisms known as extremophiles. This investigation looks at the effects of subjecting a living organism (yeast) to some extreme…
Ice Cores
In this practical activity students analyse ice cores extracted from the icy worlds of Enceladus or Europa. This resource provides information about Enceladus and worksheets for both qualitative and quantitative analyses. In the video, Steve Althorpe explains how ice cores containing minerals can be made and then analysed by the…
Rates of Reaction and Activation Empathy
High levels of ultraviolet radiation out in space drive reactions that can turn white beads into their coloured form. Students investigate how temperature affects the rate at which the beads turn back to white. At Key Stage Five, students can use the results sheet template to find the activation enthalpy. In the video, Judith…
Molecules of Life
This resource includes a suite of games designed to promote thinking, learning and understanding as well as being enjoyable and engaging. They are all based around molecules that play key roles in life on Earth. In the MolyMod video, Steve Althorpe explains how, in the Building Molecules game, students can use Molymod to link…
Life in the Freezer
If there is life elsewhere in our solar system it’s likely to live in a pretty cold environment.
