<-- watch the video to see what a choice chamber is Lesson Objective: carry out a virtual/real choice chamber experiment to see what conditions woodlice or other invertebrates prefer Click and work your way through the pages. On page 1 you need to follow the written instructions on the page. On page 2 fill in the blanks using the tool. Here are some definitions which may help you with the evaluation: 💡Accuracy: how close your measurement is to the actual reading (did you use a proper measuring tool and ensure your eyes were parallel to the scale?). 💡Precision: the smaller the measuring increment the more precise your results. For example, measuring in millimetres is more precise than measuring in centimetres. 💡Reliability: Your results are reliable if you repeat the experiment and the next set of results are very similar to the first set of results. The more you repeat your results and see this happening, the more reliable your results and experiment are. You may wish to carry out your own choice chamber experiment with invertebrates you find in your garden. You can be creative in how your choice chambers look and what conditions they test (eg/ put an ice pack under one half to see if they have a temperature preference.). Remember to return your invertebrates to where you found them as soon as your experiment is over. Always treat the animals with care. Don't forget to upload photographs and your results table if you make your own choice chamber. When you have checked your work thoroughly click to submit your work.
This experiment was designed for KS2 pupils during lockdown in 2020. It is a stand alone activity which links well in the 'Habitat' topic. It is also appropriate for KS3. For younger learners you may wish to delete the evaluation page (page 2) and insert your own questions/prompts for a response. The correct answer in the evaluations is: reliable
