A simple "jiggle" recipe. So, we would like to make a 3D point \( p_n \in \mathbb R^3\) at the \( n^{\text th} \) animation frame jiggle. One way to do this is to have a target point (\(target \in \mathbb R^3\)) which will attract \( p_n \) in such a way that it "jiggles" around his \( target \).

Each Video Lesson asks a science question, teaches students about the relevant science, and then guides students in a hands-on activity that will help answer the question and demonstrate the science. Video Lessons are NGSS-aligned and bring core science concepts to life with storytelling, animation, and photos.

The independent variable is the factor the researcher changes or controls in an experiment. It is called independent because it does not depend on any other variable. The independent variable may be called the “controlled variable” because it is the one that is changed or controlled. This is different from the “control variable,” which is variable ...
The dependent variable is the factor that changes in response to the independent variable. It is the variablethat you measure in an experiment. The dependent variable may be called the “responding variable.”
Here are several examples of independent and dependent variables in experiments: 1. In a study to determine whether how long a student sleeps affects test scores, the independent variable is the length of time spent sleeping while the dependent variable is the test score. 2. You want to know which brand of fertilizer is best for your plants. The br...
If you’re having trouble identifying the independent and dependent variable, here are a few ways to tell them apart. First, remember the dependent variable depends on the independent variable. It helps to write out the variables as an if-then or cause-and-effect sentence that shows the independent variable causes an effect on the dependent variable...
Plot or graph independent and dependent variables using the standard method. The independent variable is the x-axis, while the dependent variable is the y-axis. Remember the acronym DRY MIX to keep the variables straight: D = Dependent variable R = Responding variable/ Y = Graph on the y-axis or vertical axis M = Manipulated variable I = Independen...

How do we know that they're particles at all? Well, one experiment which adds evidence to support this 'kinetic' theory is called 'Brownian Motion'. To set up this experiment, we need: a glass 'cell' smoke from a glowing splint. a microscope with a light to illuminate the smoke particles.
How are hypotheses tested? When possible, scientists test their hypotheses using controlled experiments. A controlled experiment is a scientific test done under controlled conditions, meaning that just one (or a few) factors are changed at a time, while all others are kept constant. We'll look closely at controlled experiments in the next section.
