A scientist wants to determine the best conditions for hatching brine shrimp eggs. In a

laboratory, brine shrimp hatch at room temperature in glass containers of salt water.
The concentration of salt in the water is known to affect how many brine shrimp eggs will hatch

Design an experiment to determine which of three saltwater concentrations (2%, 4%, or
6%) is best for hatching brine shrimp eggs. In your experimental design, be sure to:
• state how many containers to use in the experiment, and describe what would be
added to each container in addition to the eggs [1]
• state two factors that must be kept constant in all the containers [1]
• state what data must be collected during this experiment [1]
• state one way to organize the data so that they will be easy to analyze [1]
• describe a result that would indicate the best salt solution for hatching brine shrimp
eggs [1

To design an experiment to determine the best saltwater concentration for hatching brine shrimp eggs, follow these steps:

1. State the number of containers and their contents: Use three containers to represent each saltwater concentration level (2%, 4%, and 6%). In each container, add a measured amount of salt to water to achieve the desired concentration. Label each container accordingly.

2. State two factors to keep constant: Keep the following factors constant in all containers:
a. Temperature: Ensure that all containers are placed in a controlled environment at room temperature, as indicated in the given information.
b. Light exposure: Keep the containers in similar lighting conditions throughout the experiment. For example, place them in an area with consistent ambient lighting.

3. State the data to be collected: In this experiment, the number of hatched brine shrimp eggs will be the data of interest. Therefore, count and record the number of hatched brine shrimp in each container after a specific time period. You can set a standard incubation period, such as 24 or 48 hours, and then observe and record the results.

4. State one way to organize the data: To make the data easily analyzable, create a table or spreadsheet. Label the columns with the different salt concentrations (2%, 4%, and 6%) and the rows with the corresponding containers. Record the number of hatched brine shrimp eggs in each container within the cells of the table or spreadsheet.

5. Describe a result indicating the best salt solution for hatching brine shrimp eggs: To determine the best salt solution, compare the number of hatched brine shrimp eggs across the different concentrations. The salt concentration that resulted in the highest number of hatched brine shrimp eggs would indicate the best solution for hatching the brine shrimp eggs.

Note: Make sure to replicate the experiment multiple times to obtain reliable and consistent results.

Since you apparently need the practice, wouldn't it be a good idea if you answered these questions?
