Ecology Practical 2 - The distribution of species across a footpath

A simple ecology practical simulation, giving students an opportunity to practice using systematic sampling to investigate changes in species richness across a footpath, before they carry out practical fieldwork.

'Fast Plants' - Rapid-Cycling Brassica Kits

Kits for 'fast plants' - follow the complete life-cycle of these fast plants in only half a term!

Investigating Photosynthesis with the SAPS / NCBE Photosynthesis Kit

This kit, supplied by the NCBE, allows students to investigate photosynthesis using algae immobilised in calcium alginate.

Photosynthesis and leaf adaptation: how sun and shade plants respond to light

In this interesting practical investigations, students look at the rate of photosynthesis in plants from different habitats, and then consider what this demonstrates about adaptation. Leaf discs taken from sun and shade plants are immersed in a sodium hydrogen carbonate solution and exposed to either white or green light. The oxygen produced by photosynthesis causes the leaves to float. The time the leaves take to float can thus be used as an indirect measure of the rate of photosynthesis.

Video demo - Investigations with Venus' Fly Traps

In this activity, perfect for STEM science clubs, students investigate what causes a Venus' Fly Trap to shut its trap. These experiments are related to a series of investigations that Darwin carried out as part of his work on evolution and adaptation. A great activity for science clubs.

Creating a Model Ecosystem with Brine Shrimps: a Science Club Activity

Have you ever thought of making a model planet where the ecosystem is almost closed to everything except light? A great idea for STEM science clubs that can be extended for ecology investigations at KS4 and post-16 biology projects.

Investigations with Carnivorous Plants: science club activity

Carnivorous plants can capture your pupils' imagination with a wide range of cunning tactics to deceive and entrap their prey. In addition a variety of experiments can be performed on the remarkable digestive physiology of these plants. These make great activities for a STEM science club, or as a an activity for a gardening club when it rains.
