This is an updated version of an existing lab. It includes some theoretical background information and the online lab which models Connell's 1961 classic competition experiment. Students can explore the fundamental and realized niches of two species of barnacles, Chthamalus and Balanus.

Online labs provide your students with the possibility to conduct scientific experiments in an online environment. Remotely-operated labs (remote labs) offer an opportunity to experiment with real equipment from remote locations. Virtual labs simulate the scientific equipment. Data sets present data from already performed lab experiments. Please use the filters on the right to find appropriate online labs for your class. Labs can be combined with dedicated Apps to create Inquiry Learning Spaces (ILSs).
If you are looking for online labs especially suitable for the curricula of Benin, Kenya or Nigeria, please visit our Collections page.

Our objective is to show experimentally that light is necessary for photosynthesis. Students can vary the distance from the light source and the colour of filter.
Learning Outcomes

Explore how the code embedded in DNA is translated into a protein. The process of converting the information in DNA into protein is a two-step process, involving transcription and translation. In transcription, an mRNA copy is made of the DNA.

Explore the role of pore size in the diffusion of a substance across a membrane. Diffusion is the process of a substance spreading out from its origin. Molecules diffuse through random molecular motion.

This lab is used to study the rate of respiration in germinating seeds having different substances such as wheat (carbohydrates), mustard (fats) and bean (proteins).

Explore how changing the DNA sequence can change the amino acid sequence of a protein. Proteins are composed of long strings of amino acids. Proteins are coded for in the DNA. DNA is composed of four different types of nucleotides.

Note: More information about collaborative inquiry simulations can be found at https://leosiiman.neocities.org/simulations.html.

Conduct the Iodine test with different food items to test for the presence of starch.

Explore the role of permeable membrane in diffusion. Diffusion is the process of a substance spreading out from its origin. Molecules diffuse through random molecular motion.

Explore how hydrophobic and hydrophilic interactions cause proteins to fold into specific shapes. Proteins, made up of amino acids, are used for many different purposes in the cell. The cell is an aqueous (water-filled) environment.
