Petri Dish Lab Report
Double-sided tape Permanent marker Distilled water Graduated cylinder 3 petri dishes Lab spoons 3 beakers Sodium chloride 3 pipettes 3 grids
Procedures:
Day 1
Gather and prepare 3 petri dishes.
Label each grid with the different percentage of salt in each solution (0.5%, 1.0%, 1.5%).
Measure and cut 1 inch of one-sided tape.
Stick the one sided tape on the side of the grid onto the back of a petri dish; repeat this for the other 2 petri dishes.
Use the graduated cylinder and collect three 30-ml salt solutions, using sodium chloride and distilled water.
Measure out (0.5%, 1.0%, 1.5%) amount of salt needed for each dish to make sure it’s an accurate percent of salt.
Mix the distilled and salt together then pour it into the correct petri dish with the label. …show more content…
Take the paintbrush and gently brush up around 20 eggs from the bag of brine shrimp eggs.
Gently tap and brush the eggs onto the double-sided tape of the microscope slides; repeat this for the other 2 microscope slides.
Examine the slides under the microscope.
Count the number of eggs on the slide; repeat for the other 2 petri dishes.
Record the data of number of eggs under “0 hours”.
Place the microscope slide in the in the 0.5% petri dish, tape-side up, and place the lid on the dish.
Repeat step step 14, but place each microscope slide in its appropriate salt solution.
Allow the dishes to sit at room temperature for 24 hours
Day 2
Examine one petri dish with a microscope.
Count the number of swimming brine shrimps. Then, with a pipet suck up the swimming brine shrimp and move them into a
