What we're studying:
Classic mechanics and kinematics
The parents of a little boy told him what chores to complete before they come back from work and as a normal little boy he decides that he has enough time to get it all done after he takes a short nap. Well this “short” nap ends up taking longer than he expects and he wakes up to a text from his parents saying how they will be home soon. He jumps out of bed and starts cleaning his house. First, he rolls the recycling out and mows the grass. Then he takes the laundry inside and cleans the bathroom. Next he goes into the kitchen, he washes the dishes and sweeps the floor. He even sets up a mouse trap to try and catch that pesky mouse. Then he moves to his bedroom. He puts all of his cars away and makes his bed. When his parents arrive at home they see how great their son worked on the house and gave him his allowance.

6.When the fence gets knocked over it pulls a string that spins another wheel and releases a marble.
7.The marble hits a tractor and sends it down a hill to mow the grass.
8.The tractor hits a string attached to the clothesline.
9.The string pulls down a clothesline and clothes fall off of the clothesline into a basket.
10.The sudden weight of the clothes tilts a first class lever that has an iron on it.
11.The iron has a string attached to it that pulls a bottle of detergent from under a plunger.
12.The plunger sits a man up in the tub.
13.The man hits a bottle of soap and sends the “bubbles” (marbles) down a funnel and into a tube.
14.The bubbles go into the kitchen sink that pulls down a cleaning brush.
15.The brush hits a can of soup and sends it down a ramp.
16.The can of soup knocks a marble down a plinko.
17.After that the marble goes into a funnel and landing in a pot.

19.The broom hits a spoon.
20.The spoon rotates and “scares” (hits) a mouse sending it down a ramp.
21.The mouse “runs” (rolls) under a table and knocks it over.

23.The mouse trap that is attached to a string pulls down a container of cars in the bedroom.
24.The container is attached to another string that pulls a blanket over the be to make it.
25.When the bed is made it triggers a piece of wood to pull up.
