Biology is the study of living organisms and their interactions with each other and their environments. It is a fascinating and complex subject that encompasses a wide range of topics, from genetics and evolution to ecology and behavior. As such, there are many potential ideas for biology experiments, some of which are outlined below.
The effect of temperature on enzyme activity: Enzymes are proteins that catalyze chemical reactions within cells. They are essential for many processes, including digestion, respiration, and metabolism. In this experiment, you could explore how temperature affects the activity of a specific enzyme, such as lactase or amylase. You could set up a series of test tubes containing the enzyme and a substrate, and then incubate them at different temperatures. By measuring the rate of reaction at each temperature, you could determine the optimal temperature for enzyme activity.
The role of genetics in behavior: There is evidence that genetics plays a role in many aspects of behavior, such as aggression, anxiety, and social interaction. You could design an experiment to investigate the genetic basis of a specific behavior, such as aggression in mice or social behavior in birds. You could use selective breeding or genetic engineering techniques to manipulate the genes of your study organisms and then observe the effects on their behavior.
The impact of pollution on ecosystems: Pollution is a major problem that affects many ecosystems around the world. You could set up an experiment to investigate the effects of pollution on a specific ecosystem, such as a pond or a grassland. You could introduce a pollutant, such as an oil spill or a chemical herbicide, and then observe the effects on the population size and diversity of the species in the ecosystem.
The effect of diet on health: Diet plays a major role in our overall health and well-being. You could design an experiment to investigate the effects of a specific diet on the health of an organism, such as a mouse or a fish. For example, you could compare the effects of a high-fat diet versus a low-fat diet on cholesterol levels or the risk of obesity.
The role of microbes in disease: Microbes, such as bacteria and viruses, can cause a wide range of diseases in humans and other animals. You could design an experiment to investigate the role of a specific microbe in a particular disease, such as the link between E. coli and urinary tract infections. You could also explore the effectiveness of different treatments, such as antibiotics or vaccines, in preventing or treating the disease.
Overall, there are many interesting and important questions to explore in biology, and the experiments outlined above are just a few examples of the many possibilities. Whether you are interested in genetics, behavior, ecology, or health, there is a biology experiment that can help you learn more about the world around you.
Biology EEI Help
Stomatal Density in Different Conditions Stomata are the areas of gas exchange in leaves. Set Set Name Slide Slide Name 4 Muscular Tissue 933517 Smooth muscle mammalian , isolated w. What do you think causes the movement of the tip? This effectively traps large numbers of algal cells in 'jelly like' balls made of sodium alginate. This suggests a good EEI with great practical significance. In this case, they use the gelatin as food, and since there are so many nutrients in it they can divide reproduce many times and accumulate in the container until we are actually able to see them. In plant biology, callus cells are those cells that cover a plant wound.
For some further advice go to OPEN INQUIRY EEI In most Queensland schools teachers provide students with a limited range of research questions to investigate, usually drawn from a single unit eg plants. Note that at high pHs, phosphorus can precipitate as phosphates and not available for growth. The following suggestion is courtesy of Adam Delroy, Moreton Bay College, Brisbane. Click The figure below on the right below has been taken from "Mechanics of Climbing and Attachment in Twining Plants" by Alain Goriely and Sebastien Neukirch, Physical Review Letters 97, 184302 2006 - A curling tendril Circumnutation showing the continuous, almost helical, curling followed by the anchor that provides tension in the filament. The method of concomitant variation: where some naturally occurring variation in some condition Variable 1 is correlated against some other condition Variable 2. Then the seeds are then ready for sowing.
Simple Biology Experiment Ideas for Kids to Spur Their Curiosity
Factors affecting enzyme function Tullawong SHS has their Year 11 Biology students perform the experiment titled "Break it down" Biology One Activity Manual, p124 - 128 as an introduction to an enzyme digestion of starch EEI. Top and bottom view of Penicillium chrysogenum growging on nutrient agar. To the sediment add 300 mL water, 2 teaspoons sugar and 2 teaspoons ginger and carry on as before. Experimental setup: Find a few friends willing to participate and measure their ventilation rates with a respirometer the human version and then subject them to different stimuli. Plant callus culture As a plant grows the cells in various organs mature and stop dividing. Does the addition of certain minerals affect the digestion rate of milk, such as PhysiCAL? Theory: The air inside of a greenhouse remains warm under bright sunlight.

Covering both the study of animals in Zoology and of the plants in Botany, the subject forms the foundation for MBBS and BSc courses. Since then the control of growth by antimicrobial compounds has grown into a multi-billion dollar industry. It involves production of plants from very small plant parts grown aseptically free from any microorganism. The copper in the bowl assists in creating a tighter bond in reactive sulfur items such as egg whites. However, when the glucose is below 1% it reacts faster than fructose.
Hint: select species for which you can obtain large number of seeds so that you can have a good experimental design. Factors to investigate include: hard seed coats common in legumes ; an impermeable seed coat prevents water uptake ; germination inhibitor causing dormancy - some seeds contain substances that prevent germination and these inhibitors are leached out over a period of time maybe years ; temperature requirement many seeds will germinate only at a particular temperature ; light requirement some seeds require light to germinate often fairly small ones or just the opposite - they won't grow except in the dark. Anthocyanins can also be found in many fruits, vegetables, and berries, such as blueberries, red grapes, red onions, and so on. The life cycle of moss begins with asexual reproduction. You would call this the "initial" acidity. Are you going to expose slides only on the windward side of the tree or on all sides.
Plenty of websites available note: biodiesel fuel from algal oil is a different process and probably too hard for senior biology. The leaves of plants in fact, of all green plants absorb this carbon dioxide and decompose into carbon and oxygen with the aid of sunlight. The webpage provides a description of the experiment with correlations to state and national science standards. A good mixed source of nitrifying bacteria and ammonium ions is potting mix. However it could be really interesting to compare simple behaviour in animals. It builds on their keen learning abilities to explore what biology as a subject offers.
If you culture under ideal conditions for 10 days you will get a graph similar to bacterial growth exponential graph. Have a look at: Microalgae Biology teacher Ivy Walsham has suggested independent variables worth considering for an EEI using microalgae: - effect of light intensity on growth of microalgae - different coloured light on growth of microalgae - effect of carbon dioxide - effect of nutrients change nitrate, phosphate etc - effect of micro-nutrients like vitamins. The skin on our fingers, toes, palms of your hands, and soles of your feet is folded into tiny ridges. The second approach gives a better experimental approach as you can control density of weeds. These biochemicals are known as allelochemicals and can have beneficial positive allelopathy or detrimental negative allelopathy effects on the target organisms.
Read more about it Independent Variable: Temperature, Salts, Humidity, Oxygen availability Dependent Variable: Rate of Decay — measured by pH, mass or temperature change The ripeness of Fruit and Vit C content Similarly to the experiment on the rate of decay, you can also measure how quickly fruits ripen, and which factors affect this ripening. I suggest measuring the concentration of glucose. There are two independent variables: "time" and "amount of fertilizer" but they can be examined separately. The effect of exam conditions on a physiological feature of the body. Theory: Pollution need not necessarily be caused by organic compounds such as particulates like smoke and dust like smoke and dust.
