Artificial Selection: Biology Lab

1. Artificial Selection: Biology Lab

Natural selection is a major way that evolution works, but what happens when humans get involved? In this lesson, we'll see how humans influence the characteristics of a population through artificial selection.

Mathematical Modeling - Hardy-Weinberg: Biology Lab

2. Mathematical Modeling - Hardy-Weinberg: Biology Lab

What is a scientific model? How can we create them? How can they be used in biology? In this lesson, you'll answer all of these questions as you explore how a model called the Hardy-Weinberg theorem can be used to predict how a population will change over time.

Comparing DNA Sequences to Understand Evolutionary Relationships with BLAST: Biology Lab

3. Comparing DNA Sequences to Understand Evolutionary Relationships with BLAST: Biology Lab

About 90% of human DNA is the same as mouse DNA, and that's a good thing. In this lesson, you'll explore how scientists use genetic similarities to determine how living things are related.

Diffusion and Osmosis: Biology Lab

4. Diffusion and Osmosis: Biology Lab

Molecules are always on the move thanks to kinetic energy. This energy makes diffusion and osmosis possible, two processes used by cells to maintain homeostasis. In this lab, we'll look how osmosis and diffusion work and what factors affect them.

Photosynthesis: Biology Lab

5. Photosynthesis: Biology Lab

Plants and other organisms that have the pigment chlorophyll can do something that no other living creature can - capture light energy from the sun and use it to make chemical energy through photosynthesis. In this lab, we'll see how we can set up an experiment to measure the rate of this important process.

Cellular Respiration: Biology Lab

6. Cellular Respiration: Biology Lab

Oxygen is essential to life. Without this molecule, we would not be able to complete cellular respiration, the process which creates much of a cell's energy. This lab will explore how we can quantify this process by designing a procedure to measure respiration in germinating seeds.

Cell Division - Mitosis and Meiosis: Biology Lab

7. Cell Division - Mitosis and Meiosis: Biology Lab

Organisms use cell division to replicate, grow, and, in the case of a process called meiosis, to make gametes for reproduction. This lab explores the processes of mitosis and meiosis through both physical and mathematical modeling.

Enzyme Activity: Biology Lab

8. Enzyme Activity: Biology Lab

The amount of energy necessary to start a biochemical reaction is called activation energy. Special proteins called enzymes lower activation energy, allowing life to exist. In this lesson, explore how enzymes work and see what conditions affect them.
