It’s that time of year again, and the Biology Internal Assessments (IA) are necessary to complete your IB classes. However, the only downside is that it can be a bit of a hassle to spark your creative mind and generate some unique ideas.
To help you with this decision, we have created a comprehensive list of Internal Biology Assessments to help you finalize your decision and officially complete your IB classes. Want to know about them? Read below.
The first inspiring internal assessment in biology to consider is the effects of salt on seed germination.
Halophytes, also known as salt-tolerant plants, can grow in soil or water with high salinity, while normal plants do not. This internal evaluation wants to show the difference in germination between halophytes and normal seeds.
Vegetables decompose due to damage caused by small microorganisms such as bacteria and mould, but how can we reduce this? In this internal assessment, you will investigate how different environments increase or decrease the rate of decomposition.
The following internal assessment can be simple if you can get enough people together to do the test. To do this, you will use an online or book-based colour vision test and measure which factors affect colour blindness.
As in the previous experiment on decomposition, for this internal assessment you will measure the rate of ripening of the fruits as a function of numerous variables for this internal assessment.
Next, you could measure the effect that household cleaning products have on seed germination. This internal assessment will be useful for your IB class, as you can investigate whether household cleaning products positively or negatively affect germination.
The hormone auxin plays a key role in directing plant growth. However, this internal evaluation finds out whether the type of light increases or decreases its efficacy.
As we all know, milk spoils. This is due to the reproduction and development of lactobacilli. This is another exciting internal Biology assessment, as you can test the rate of spoilage depending on a lot of environmental conditions.
Another internal assessment you can make for Biology is reaction time with age. It is obvious that many people assume that reaction time decreases dramatically with age, so why not check if this is true? The only real downside to doing this as an internal assessment is that it can be quite difficult to find enough willing applicants.
After reading the above, I hope you now have a general idea of the Biology Internal Assessment you are going to take to complete your IB class. However, choosing one at random may not be the best option, and you should consider the following to ensure that you have a ‘good’ internal assessment.
The best types of Internal Assessments in biology are those in which you are generally interested in research. Including this, you must show that you have done in-depth research and that you now fully understand the project.
To get an excellent internal assessment in biology, it doesn’t necessarily have to be the most complex. But one thing your internal assessment does require is a clear research question, a coherent structure and an easy-to-follow personal commitment that quickly demonstrates the student’s knowledge of the topic.
Hopefully, having read the above, it has fired your imagination, and you can now finalise your Biology Internal Assessment. Now what are you waiting for – get experimenting!
