Observe and compare wild plants growing in two areas that have a different environmental factor.
Work in two grassy areas that have a different environmental factor, such as one with light and one with shade. Using a scientific method called sampling, investigate the areas to find out if the environmental factor affects what grows there. ‘Randomly’ sample each area by using a hula-hoop (or something similar) placed on the ground. Estimate the percentage plant cover inside the hula-hoop then identify, count and record the plants you find, excluding grass. Repeat the process a number of times at different locations in the same area. Compare your results and observations from each area to see the effect of environmental factors on plant growth and distribution.
Collect holly leaves from trimmed and untrimmed trees. Observe how holly adapts and becomes pricklier to survive better.
Go outdoors and collect holly leaves from two separate holly trees – one trimmed and one that has grown undisturbed. Count the number of prickles on the leaves, calculating an average number of prickles for trimmed versus untrimmed holly.
