Question

Помогите пожалуйста !!!Срочно!!!Даю 65 баллов!!! 2. Игорю и Ларе пришлось решать проблему: каким образом быстрее всего можно вырастить растения подсолнечника из семян? Одним из возможных исследовательских вопросов, который соответствует проблеме Игоря и Лары, является вопрос „Как влияет влажность на скорость прорастания семян?“ Чтобы ответить на этот вопрос, нужно провести опыт. Что нужно Игорю и Ларе для проведения этого опыта? Перечисли необходимое для опыта оборудование, материалы и вещества.

Answer 1

Answer 3

Equipment, Materials, and Substances Needed for the Experiment

To answer the research question "How does humidity affect the speed of seed germination?" Igor and Lara will need to conduct an experiment. Here is a list of the necessary equipment, materials, and substances they will need:

1. Seeds of sunflower: Igor and Lara will need sunflower seeds to conduct the experiment. These can be obtained from a local gardening store or online seed suppliers.

2. Containers: They will need containers to plant the sunflower seeds. These can be small pots, trays, or cups. The containers should have drainage holes at the bottom to prevent waterlogging.

3. Potting soil: Igor and Lara will need potting soil to fill the containers. This soil should be suitable for growing sunflowers and should provide the necessary nutrients for germination.

4. Water: Water is essential for seed germination. Igor and Lara will need a source of clean water to moisten the soil and maintain the desired humidity levels during the experiment.

5. Humidity control devices: To control the humidity levels, Igor and Lara can use various devices such as a humidifier or a hygrometer. A humidifier can increase the humidity in the experimental environment, while a hygrometer can measure the humidity levels.

6. Labels: It is important to label each container to keep track of the experimental conditions. Igor and Lara can use small labels or tags to mark each container with the corresponding humidity level.

7. Light source: Sunflowers require adequate light for germination. Igor and Lara should place the containers in a well-lit area or provide artificial light using grow lights if natural light is insufficient.

8. Notebook and pen: Igor and Lara should keep a notebook to record their observations, measurements, and any other relevant data during the experiment. A pen or pencil will be needed to write down the observations.

9. Timer or clock: A timer or clock will be useful to measure the time it takes for the seeds to germinate. Igor and Lara can use a digital timer or a stopwatch.

10. Protective gear: It is advisable to wear gloves and use any necessary protective gear when handling soil, seeds, or any potentially harmful substances.

Please note that this list is not exhaustive, and depending on the specific experimental setup and requirements, additional equipment or materials may be needed. It is always a good idea to plan the experiment in advance and ensure that all necessary items are available before starting.

I hope this helps Igor and Lara with their experiment! If you have any more questions, feel free to ask.
