• Only tissue paper

• Only paper towels

• Only Windex

How do living things compare to nonliving things at a microscopic scale?

• Claim A: On a microscopic scale, living things and nonliving things are made up of cells.

• Claim B: On a microscopic scale, nonliving things are more complex than living things. However, living things can grow and nonliving things cannot.

• Claim C: On a microscopic scale, only living things are made up of cells, but both living and nonliving things have structures that can only be seen with a microscope.

How do human organs compare to each other at a microscopic scale?

• Claim A: On a microscopic scale, the cells of human organs have different shapes and sizes and have different specialist roles.

• Claim B: On a microscopic scale, the cells of human organs have different sizes, but are all the same shape.

• Claim C: On a microscopic scale, the cells of human organs are all the same size, but have different shapes.

How do humans compare to plants at a microscopic scale?

• Claim A: On a microscopic scale, human and plant cells are identical to each other.

• Claim B: On a microscopic scale, human and plant cells are different shapes and sizes.

• Claim C: On a microscopic scale, the cells of plants are all identical, and human cells have different shapes and sizes.

Renee is designing an investigation using a microscope to COMPARE cells in different living things.What should be her MAIN consideration when designing the investigation?

• a. The number of cells collected within each sample, so that the student can record the total cells

• b. The variety of living things selected, so the student can examine the cells of many living things

• c. The temperature of the lab during the investigation, so the student can control how the environment affects the cells

• d. The style of the microscope to examine the cells, so the student can take pictures of the slides

Scientists need your help with a paper they plan to publish. The paper is about a new organism they’ve discovered. In this paper, they want to discuss what type of organism it is and describe how it functions. First, the scientists need you to examine some cell samples to help confirm what type of organism they have found. The samples they collected are shown below. Images were taken using a microscope. The scientists use this data to confirm that the organism they discovered is a living thing. How do the photos they collected provide evidence that they have discovered a living organism? (1 paragraph minimum).

Doctors use many methods to determine why a patient is sick. Match statements to the different types of evidence from cells doctors can use to figure out why someone is sick:

• Different types of cells have different functions and look different

• Living things are made of cells and nonliving things are not. A sample could include nonliving things like dust in a lung tissue sample.

• There could be fungi, parasites, or unicellular organisms like bacteria in the sample. These would look different from the patient's cells.

• There are not different types of cells. All have the same size and shape regardless of organism.

What is the primary function of the objective lens in a microscope?

• To magnify the specimen

• To illuminate the specimen

• To hold the slide in place

• To adjust the focus
