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.

CASE 1: In the fermentation experiment you may, for example, choose to have the "temperature" as the independent manipulated variable say 0°C,10°C, 20°C, 30°C. 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 effect of exam conditions on a physiological feature of the body. The amount of water added was then reduced slightly to accommodate for the water in the mush. If a person exercises regularly they should have a better level of fitness, this might mean that their heart rate increases by less in the short burst of exercise than someone who does no regular exercise. As such, there are no specific materials that you need, a large bin or a tank is required to store the waste and earthworms are to be put in.
Perhaps some form of experiment using isotonic solutions on slightly dehydrated muscle tissue from a chicken leg, or liver would work. For example, cars brought in from overseas are steam cleaned before being delivered to their owners. She says "Culture the microalgae in test tubes and record the daily growth. It is said to have been denatured. Of course the ideas are just ideas, nothing is specified and all the details will need to be explored and evaluated by students during their investigations. So we will ensure that our body receives all the necessary nutrients in sufficient amounts by consuming a range of various foods. Experiment Results: Plants need water for sustenance; this simple experiment demonstrates how water is absorbed by the stalk, and distributed throughout the plant to its leaves and flower.
Senior Year Biology EEI Experiment Ideas : biology
Discussed below are some of the popular Biology project for class 11th with required materials. There are two independent variables: "time" and "amount of fertilizer" but they can be examined separately. In this study, the researchers measured competitive interactions among an invasive grass and two Australian native grasses that are functionally similar and widely distributed. She is photographing the tubes, so she said. This research furthers the possibility of using allelochemicals as growth regulators and natural herbicides, to promote sustainable agriculture.
In the second dish, do the same with neosporin. Processes such as diffusion and osmosis as well as the effect of chemicals on components of cell membranes, or on enzymes could be included in the theory. This photo shows Acacia baileyanna seeds with the radicle emerging after boiling water treatment. Click Fungus decomposing Eucalyptus regnans litter. Brian and also Louis G.
There are examples of invasive species affecting native species by competitive exclusion and ultimately extinction. A pollen calendar Pollen in the air may cause hay fever in susceptible people. That is, he had two manipulated variables the continuous variable - salt concentration and a categorical variable - the method of application either sprinkler or drip. Should flavoured milks be made with low fat milk? There may be several 'control' treatments necessary. Penicillium chrysogenum as a safe alternative for use in schools.
Simple Biology Experiment Ideas for Kids to Spur Their Curiosity
Comparing boys and girls for example will be impossible, unless the sample size is very large. Experimental Setup: Create different environments for vegetables to decay in and measure the decay over a fixed period. Light: algae can grow at higher light intensities than normal daylight even in Northern Australia but can take up to 4 weeks to acclimatise to high light. There is room for some good quantitative numerical testing. It would be good to know how much water is present in the potting mix and you can do this by taking a weighed sample and drying it in the oven at 100°C gravimetric analysis. Practical procedures and controls will be the challenge, but data should be easy to record if the seedlings grow.
You may wish to compare the rate of decay of material submerged at different depths or buried in the substratum. Mistletoes are dispersed by birds. How are you going to quantify the magnitude of the movement? At the end of a long endurance event cramps and muscle fatigue will be evident but this is not possible to recreate in the lab in school. Measuring sugar concentration with a Brix hydrometer. You can easily try it at home and amaze your friends and family. They used to get their chervil seeds from Beautanicals at Helidon, a few hours west of Brisbane, phone 07 4697 6306 or email Radish seedling are great for a winter EEI. There needs to be some clear links to the biology of blood pressure and how exercise affects it.
Investigation of SA:vol on the rate of diffusion This is a standard lab and the challenge will be to ensure that it is put into an interesting biological context. Thanks to Caitlin and Phoebe. Growth of weeds Many persistent weeds owe their nasty reputation to their ability to regenerate from either seeds or from vegetative structures and to their ability to grow up from considerable depths. Click Eucalypt leaves were placed by CSIRO at two sites in an intermittent stream during summer to examine the hypothesis that terrestrially-exposed leaf litter accumulates a richer microbial flora than submerged leaves. Each dish was lined with two pieces of filter paper.
