Brine Shrimp Experiment Insights

Miss Patsy from Castile Innovation Lab introduces a lesson on brine shrimp, focusing on their range of tolerance. The lesson includes a recap of a previous investigation and sets up a new experiment to determine the optimal salt concentration for brine shrimp hatching. The experiment involves varying salt levels in different cups and observing the hatching results over 24 to 48 hours.

What is the main focus of the lesson conducted by Miss Patsy?

• The diet of sea turtles

• The lifecycle of butterflies

• The range of tolerance of brine shrimp

• The habitat of polar bears

What is the typical habitat of brine shrimp?

• Rainforests

• Salt lakes or brine ponds

• Freshwater lakes

• Deserts

Brine shrimp are related to which of the following creatures?

• Frogs

• Birds

• Crabs

• Snakes

What is another name for brine shrimp?

• Sea monkeys

• Water bears

• Ocean crabs

• Lake lobsters

What is the length of a typical brine shrimp?

• 3 centimeters

• 2 centimeters

• 1 centimeter

• 0.5 centimeters

In the initial experiment, which salt concentration resulted in brine shrimp activity?

• No salt

• Two teaspoons of salt

• Four teaspoons of salt

• Six teaspoons of salt

What was the purpose of expanding the experiment with more salt concentrations?

• To determine the range of tolerance for brine shrimp

• To find the fastest hatching time

• To see if brine shrimp can survive in freshwater

• To test the effect of temperature on brine shrimp

How many different salt concentrations were used in the expanded experiment?

• Nine

• Twelve

• Three

• Five

What is the expected time frame for the brine shrimp to hatch in the experiment?

• 12 to 24 hours

• 24 to 48 hours

• 48 to 72 hours

• 72 to 96 hours

What is the main goal of observing the hatching of brine shrimp in different conditions?

• To measure their growth rate

• To see which conditions they prefer

• To observe their feeding habits

• To determine their color change
