A researcher brings 9 students into the lab and separates them into three different groups. 3 of the people are asked to write about a time they were socially excluded, 3 are asked to write about a time they were included, and 3 are asked to write about their morning yesterday (presumably nothing special happened?). They are then asked to rate their mood on a scale of 1-20 (higher numbers indicate a more positive mood). The researcher believes that thinking about past social situations will affect people's mood, as if they were reliving those situations.

Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
