CATDOLL : CATDOLL: When exploring the "effect of light on the life of pillbugs", some people used mealworms, which are easy to obtain and easy to observe and count, to replace pillbugs for experiments, and the results were very good.

1. When exploring the "effect of light on the life of woodlice", some people used mealworms, which are easy to obtain and easy to observe and count, to replace woodlice for experiments, and the results were very good.

(I) and (II) Based on the experiment of exploring the effect of light on the life of woodlice, the question raised is: Does light have an effect on the life of mealworms? We can make a hypothesis: light affects the life of mealworms or light does not affect the life of mealworms.

(iii) and (iv) When setting up a control experiment, you should set up a control group with the conditions to be explored as the only variable according to the conditions to be explored. From the question, we can see that the variable of this exploration experiment is light: bright and dark (covered with an opaque black cardboard on one side and a transparent glass plate on the other side). The only variable in the control experiment is light, so you should set up a control experiment with the same conditions such as temperature and humidity except for light. That is, put a layer of moist soil in the paper box, cover one side with a glass plate and the other side with paperboard with the midline of the horizontal axis as the boundary. In this way, two environments of light and dark are formed in the box.

(V) Conclusion: Light has an impact on the life of mealworms, and mealworms like to live in a dark and humid environment.

(VI) Expression and communication: In order to reduce the influence of subjective factors on the experimental results, reduce experimental errors, and improve credibility, the number of pillbugs should not be too small. Too few pillbugs may be accidental, and too many pillbugs may increase the difficulty of the experiment. Ten pillbugs should be randomly selected, not deliberately selected, and the average value of multiple experiments of each group in the class should be taken. In this way, the results of multiple experiments can reduce errors, because there is a certain degree of accidental and error in one experiment. This is the most realistic value, otherwise it is not enough to explain the problem.

So the answer is:

(1) Raising questions;

(III) Place a layer of moist soil in the paper box, and cover one side with a glass plate and the other side with a cardboard, with the horizontal axis midline as the boundary. In this way, two environments, bright and dark, are formed in the box, which is a control experiment with light as the only variable.

(iv) illumination;

5. Light has an impact on the life of mealworms

(6) To reduce the influence of subjective factors on experimental results and reduce experimental errors.

2. Taking the effect of light on the life of mealworms as an example, we explore the effect of ______ factors on organisms.

A controlled experiment is an experiment in which all other conditions are the same except for the condition that is different when studying the effect of a condition on the research object. The different conditions are experimental variables. Let's take the effect of light on the life of mealworms as an example. The only variable in the experiment is light. Through analysis, we know that light is a non-biological factor and mealworms are biological factors. Therefore, we take the effect of light on the life of mealworms as an example to explore the effect of non-biological factors on biological mealworms.

So the answer is: non-living things.

3. Buy some mealworms for experiment. Please let me know if you know. Thank you!

I wonder if you are buying mealworms to learn how to raise insects, or to use them as experimental materials for other experimental projects? If the quantity you need is not large, you can go to the local flower and bird market to have a look. There are also fishing tackle stores that sell mealworms.

4. When studying the effect of light on the life of mealworm larvae, (1) the question raised was ______ (2) the hypothesis made was ______ (3) the experiment was designed

(1) Ask questions: Try to find questions related to biology from daily life, production practice or study. Based on the living environment of mealworm larvae, the question asked is: Do mealworm larvae like to live in a dark environment?

(2) Make a hypothesis: Use existing knowledge to propose possible answers to the question. Estimate the testability of the hypothesis. From this, we can draw the hypothesis that mealworm larvae have a habit of avoiding light, and light will affect the life of mealworm larvae.

(3) The variable in this experiment is light. When designing the experiment, the mealworm larvae should be provided with two environments, bright and dark, for comparison. Observe the phenomenon, analyze the results, and conclude that light affects the life of mealworm larvae.

Controlled experiment: When studying the effect of a certain condition on the research object, the experiment conducted with the same conditions except for this condition is called a controlled experiment. A group of controlled experiments are set up according to the variables to make the experimental results convincing.

So the answer is:

(1) Do mealworm larvae like to live in dark environments?

(2) Mealworm larvae have the habit of avoiding light, and light will affect the life of mealworm larvae (or light will not affect the life of mealworm larvae)

(3) Dark and bright light control experiment

5. First grade biology: The impact of temperature on mealworms, make a hypothesis.

Assuming that temperature has an effect on mealworms, we are doing experiments

6. We used about 10 mealworms for the experiment in class. What would happen if there were too few? What would happen if there were too many?

Too few experiments will not be comparable, too many to count, that's what I wrote
