Explain why you chose this method and not others. Before I start, try to put yourself in the shoes of a researcher who receives funding from a university. The table also shows three repeat sets of data of each participant - each set having two values of a negative and positive value , the positive added to the negative value is the vital lung capacity of the participant Refer to Background Information. Do you continually give advice to the students during the class period or do you simply give them a specific one hour time frame and collect them at the end of class and mark it? This might make an interesting investigation. The precise meaning of the command terms used in the criteria can be found in the glossary of the subject guides. Biology Labs Online is a collaboration between the California State University system and. Source: So, finally, some ideas for you: 路 Investigate intermolecular forces 路 Investigate solubility 路 Investigate heats of neutralisation 路 Investigate an aspect of a redox cell 路 Investigate electrolysis.

Some diseases spread through direct contact, others are transmitted by an insect vector. This is a list of possible sites for students to use as online labs. . It is also essential to be fully acquainted with the marking of the exemplars in the teacher support material. Testing spoilage of milk in different conditions.

The type of respiration that occurs is called aerobic respiration. Of the topics that are still in the running, brainstorm ways you might find the answer to your questions. You have to show that the data has been carefully selected, and that measures have been taken to ensure that other factors which might affect the data have been controlled, by careful selection of the data used. Perhaps some form of experiment using isotonic solutions on slightly dehydrated muscle tissue from a chicken leg, or liver would work. Now choose your best question. For any other use, please contact Science Buddies.

Lab Work

The biggest obstacle to doing well in the individual investigation for most students is not putting enough thought and effort into coming up with a good question. This study could be an investigation of how effectively the toothpaste inhibits the growth of bacteria according to the scale of the chemicals in the toothbrush. This mucus also allows the organisms to adhere themselves to the surface in order to ingest food or to excrete. Comparing boys and girls for example will be impossible, unless the sample size is very large. It declines because yeast cells enzymes start to denature.

Investigation Ideas

Starting with a process which requires diffusion in living cells will help the topic to be interesting and will show some personal engagement. What do you think of this? How do you handle these design lab aims during a class period without giving advice or ideas? There are plenty of factors to control which makes this investigation difficult and if there isn't enough data or the controls are not in place this could lead to a low mark after much work. The effect of reading different genres of literature on blood pressure and pulse rate. Which pigments are made first in a growing leaf, or are all the pigments made at the same time? This is an interesting quantitative method to estimate glucose concentration. Investigation of Age and reaction speed This is an investigation to test a hypothesis that reaction time will slow down with age. As they say, in one end and out the other! Biology Labs Online is a collaboration between the California State University system and.

Investigation of the effect of music on the heart rate. There are also many factors to consider in the type of reaction speed test that is used and there are also problems associated with the learning of the skill during the experiment. This is nice project if there is a specific environmental gradient in the site being investigated. Using nationally published data on epidemiology and weather data is certainly possible and it could happen that there are correlations between climate and some disease outbreaks this will need explaining in terms of the mechanisms of transmission of the specific disease. There are many possible variations, perhaps the presence of animal excrement could be the causal factor, otherwise some species may be more resistant to scratching and disturbance, caged animals can selectively graze on parts of a lawn, just to mention a few ideas. I'm not going to take the same ones you used I would just like an idea so I don't end up killing them again I managed to pull off an ia on putting salt in apple juice last year :p Juiced them, mixed in different concentrations of salt, let them sit and brown, and then tested the levels of browning with a spectrometer, i was measuring if salt inhibited catecholase basically does salt preserve things, plot twist it does lol My bio teacher said that psychology topics don't count as biology because it's a social science. Secondly, there is no need to worry about the safety element of things 鈥 although the labs that the students design should be safe and in theory, they should be possible to do in your school lab.

Controlling other factors which affect germination and collecting a large enough data set will also be good challenges for a Biology student to work out. Could the position of the body affect blood pressure and thus heart rate? They need to collide in order for the reactions to occur. It can though be easily be adapted for other statistical approaches such as the chi-square testing. Examining the effect of household cleaning products on the growth of house plants This could be a difficult investigation to do quantitatively unless there was a longer time period available to observe growth. I feel that my idea is a bit too complicated to do a lab in class because it is also based on organic chemistry. There may be a combination of roles for plant roots and bacteria in the substrate and both of these link to the nitrogen cycle and so would allow for a detailed hypothesis and a focused research question. This is a neat idea to immobilise algae in alginate beads and use them to investigate photosynthesis rate.

Fuzzy things are often cute, but not when that fuzziness is mold on your strawberry鈥攜uck! Hope this helps a bit. A more concentrated sucrose solution will cause the mass of potato chips to decrease as water is likely to move out of the cells. This makes it even clearer what you are measuring. In all these respects, water is essential for the germination of seeds. Then is is going to be a challenge to design a method of data collection which controls all the possible variables.

23 Ideas for Science Experiments Using Plants

It is more likely that molecules will have the sufficient activation energy at high temperature due to the increased kinetic energy in the molecules. Controlled Variables Measures to control the controlled variables Units Effect on results Concentration of yeast Yeast solution should be drawn from a single stock solution to prevent fluctuations in concentrations. I would love to hear about your experiences below. It is vital to decide which one of these is the focus of the research question, at the beginning. Finlay in the Journal of agricultural and Food chemistry, 2015 Do plants grow faster in soil which has more microbial activity respiration This investigation could be a nice way to combine two standard procedures, one to estimate the rate of respiration in the soil and another to estimate the rate of growth of a plant. In this experiment, you will make models of seeds and fruit to investigate dispersal by wind and to evaluate the relationship between the structure of the seed and its ability to be dispersed by the鈥 Plants need nitrogen to grow healthy stems and leaves. Given the range of possible tasks it is impossible to give a single template that covers the needs of all reports.
