Mitosis Lab
In the mitosis lab, students use a determination of the stages of cell division and mitotic index to develop and demonstrate an understanding of how variations in cell division/mitosis influence cancer and chemotherapy treatment.
Learners start the activity by developing three questions about mitosis and cancer based on a scenario where a family friend has been diagnosed with cancer. These questions are then addressed through review of background knowledge on mitotic stages, followed by hypothesis development and the completion of two experiments.
In the first experiment, students collect and analyze data on mitotic index in various tissue types and cancer to understand how cancer cells differ from normal cells. In the second experiment, they prepare and view slides from cancer cells with and without Taxol chemotherapy treatment in order to determine which stage of mitosis is affected by this anti-mitotic drug.
Students wrap up with a post-lab in which they interpret their results, both by returning to the original scenario and by applying the new information and concepts learned to
broader scenarios.
Each lab starts off presenting students with a real-world scenario. This engages students right from the start with a story they can relate to and care about, providing a connection between the lab and their own experience. Then, the Introduction recaps key background knowledge for students.
In the pre-lab, students are asked to build a hypothesis, design an experiment to test their hypothesis, and then make a prediction as to what will happen in the experiment.
The virtual lab bench is a risk-free setting with guided feedback that allows students to make mistakes and learn from them. As students collect data, immediate feedback and hints guide them to a solution rather than simply providing the correct answer.
Once experimental data is collected, the student will graph and analyze that data in post-lab activities, interpret the results, and reflect on their hypothesis.

Real-world examples engage students with scenarios they can relate to and care about, providing a connection between the lab and their own experience.
Lab story and introduction
Click through the videos to experience highlights from the mitosis lab introduction.
Interactive Lab: Protein Structure and Function
Students explore a 3D model of a strand of human hair to learn about its structure and composition.
Interactive Lab: Microscopy
Students test their knowledge by sorting images according to which microscope was used to view
each object.
In this mitosis example, students learn about a specific patient and consider research questions that will guide their lab experience.
The story concludes with a summary of Research Questions and then students are ready to start the introduction.

Pre-lab
Next, they design an experiment to test their hypothesis.
In predicting the results, students decide which chart best represents what they think their experiment outcome will be.

Interactive Lab: Diffusion and Osmosis
Students select the hypothesis that they think best describes how molecules will move through a selectively permeable membrane. There is no wrong answer — their experiment will either support or disprove their selection.
Interactive Lab: Diffusion and Osmosis
A drag-and-drop activity guides students in defining the steps they’ll need to take to test their hypothesis.
At their own pace, students review the background knowledge they need to be successful in the lab.
Engaging knowledge checks reinforce students’ foundational understanding.
A variety of activity types and immediate guided feedback help students solidify their understanding along the way.
The lab introduction concludes with a summary. Students are now ready to move on to the pre-lab.
Students are asked to build a hypothesis in two steps, first what they think will happen and then why.
The pre-lab concludes with summary information that prepares students to move on to the lab bench.
Click through the videos to experience highlights from the mitosis experiment.
Students will see the instructions for the experiment on the left-hand side of the lab bench at all times for easy reference. Students can explore any of the materials on the lab bench.
The instructions panel can be hidden at any time. Here, students select and label their samples.
Next, they select the appropriate dropper, add the Taxol to the treatment well, and return it to
the incubator.
The slides are prepared while the treatment incubates. Tasks like labeling slides keep students responsible for the same details they’d need to adhere to in an in-person lab.
They now add 1 drop of DNA stain to each slide.
Students continue through the steps at their own pace. At this point, they remove the well plates from the incubator.
The steps come together with the incubated treatments being added to the prepared slides.

Interactive Lab: Microscopy
Students use the virtual lab bench to practice using a compound light microscope, learning its parts and functions.
Interactive Lab: Scientific Method
Students step through a simulation, testing to see whether hand soap or hand sanitizer is more effective at reducing bacterial diversity.
The experiment
Meaningful right and wrong answer feedback is provided throughout the experiment, allowing students to make mistakes and correct them.
Some activities let students choose how they prefer to complete them. Here, they can count each cell by selecting them on the screen or they can enter their count directly in the data table.
The summary allows students to view the data they collected against the initial research questions.
Click through the videos to experience highlights from the mitosis post-lab.
Post-lab
A variety of activities help students analyze and interpret the data they collected.
Graphs and guiding questions support analysis, helping students conclude whether the experiment supports their hypothesis.
The end of the post-lab brings students back to the story they were introduced to in the beginning, again grounding the experiment in a real-world scenario.
This concludes the Pearson Interactive Lab on targeting mitosis to fight cancer.

As a part of the post-lab process, students reflect on how well their hypothesis was supported by the data collected during the experiment.
Interactive Lab: Photosynthesis
Students practice important graphing skills including labeling each axis correctly.
