Mad Science Station Lab Seasons & Tides If you have never used my Mad Science Station Labs before please download the FREE Start-Up pack from my TPT store. It will provide you with all of the signage and best practices in order to run the station labs in your classroom. The large directions cards included in this file are intended to be read by the leader of the group once the students get to the station. The smaller task cards can be read by another group member. I prefer that each student do their own lab write-up (included at the end of this file), so that they may use it for reference at a later date. The answer key is provided at the end of the document. Lastly, if any of the internet resources no longer work for some reason please let me know via email at madsciencelesson@gmail.com. I cannot guarantee that all resources will be available, but I tried to choose ones that have been around for many years.
Mad Science Station Lab Seasons & Tides - Teacher Directions Explore It! I will spend much of my time at this station making sure that the students are building the models correctly. You will need 3 balls (Sun, Moon, Earth), piece of blue yarn, and another ball (earth) with an axis through it. I use foam balls or tennis balls and a dowel for the axis. Look at the image on the card to visualize how the yarn is used for the tide. Illustrate It! You will need to set out map colors and markers at this station. Organize It! The cards for this activity are attached near the end of this file. Print several sets and then just put them in the basket for kids to pull from. This is a good one for later in the week to demonstrate mastery too! Students should be encouraged to do the Research and Explore station before attempting this one. Write It! Students should be encouraged to do the Research and Explore station before attempting this one. Read It! Print several different copies (I use 6) of the reading passage so that multiple students can read at different paces Watch It! The video is on the free website StudyJams (LOVE this site).

Read It! Station Directions Each member of the group will read the passage and answer the questions from the task cards on the lab sheet in the Read It! section. It is important to remember that the answers will come directly from the reading passage.
What if There Were No Seasons? Without Earth's tilt, humanity would not be in the same state that it is today. Forget modern technology, the steam engine, or sliced bread. In a world without seasons, there wouldn't even be wheat. According to Don Attwood, an ecological anthropologist at McGill University in Montreal, humans would probably never have advanced past a state of living in small, scattered settlements, scrounging for survival and often dying of horrific insect-borne diseases. Scientists think an Earth without a tilt would be split into climate bands that would get progressively colder as you moved away from the equator. Humans would never survive the continuous winter of the high latitudes, and so we would likely all live in the planet's tropical midsection. If the habitable world were a humid tropical zone like a rain forest, then unrelenting rainfall would quickly erode soil in any areas cleared for farming, and would take away nutrients down below the root level. Even today only low-density populations live in the rain forests of the world. On top of our problems with agriculture humans would also be plagued by disease pathogens which thrive in warm, humid environments. Winter controls the growth of these deadly pathogens and their insect hosts. It has been vital for human development. The Industrial Revolution has roots in the existence of winter also. Though it usually isn't explained this way, modern technology can be thought of as a by-product of the development of new ways to keep warm. Lucky for us, the moon ensures that Earth's tilt remains stable, so seasons won't ever vanish completely.
In the second paragraph the word scrounging means? A. stirring B. offer C. obtain D. seek What would be another good title for this passage? A. The Reason for Seasons B. What If The Earth Had No Tilt? C. Winter is Beneficial D. Seasons Happen Every Four Months Why would Earth be the warmest near the equator if there were no seasons? A. The equator would get the most direct sunlight B. The equator is closest to the Sun C. The equator would have the most wildlife D. The full moon would always be out. According to the passage, what is one benefit of winter? A. It allows for diverse life B. It keeps us cooler C. It keeps food fresh D. It controls the growth of deadly pathogens

Research It! Station Directions Each member of the group will go to the website listed on task card #1 Complete the task cards in order. Every student will answer the questions from the task cards on the lab sheet in the Research It! section.
1. Go to http://goo.gl/pvrrza 2. Check the Include Sun box 3. Check the Run button 1. When the Sun, Moon, and Earth are in a straight line this is called a spring tide. 2. When the Sun, Moon, and Earth make an L-shape this is called a neap tide. 1. Go to http://goo.gl/y80epw 2. Click on Start Animation (bottom right) 3.

Explore It! Station Directions One member of the group will read the task cards in order. The group will be responsible for completing each of the tasks that are being read. Each member of the group will then write their conclusions down on the lab sheet in the Explore It! section.
Yarn E 1. Setup a model on the table using the image below. Use the yarn to represent the oceans and tides. M Sun 1. When the Sun, Earth, and Moon are all in a straight line this is called a spring tide. The moon can also be on the opposite side of the Earth and a spring tide will still occur. Yarn M E 1. Setup a model on the table using the image below. Use the yarn to represent the tides around Earth Sun 1. When the Sun, Earth, and Moon form a 90 degree angle this is called a neap tide. The moon can also be on the opposite side of the Earth in this model and a neap tide will still occur.
Answer the following questions on your lab sheet. 1. What moon phases are present during the spring tide? 2. What moon phases are present during the neap tide? 3. What force causes the tides? Setup a model using the Sun and Earth using the image below. 1. What season would it be in the northern hemisphere? 2. What season would it be in the southern hemisphere? Sun E Revolve the Earth around the Sun (counter-clockwise) until you get to the position in the image below. Keep the axis pointed in the same direction the entire time. 1. What season would it be in the northern hemisphere? 2. What season would it be in the southern hemisphere? E Sun

Watch It! Task Card #1: As the Earth rotes we will have high or low tides. When we face the moon, or the moon is on the opposite side of Earth from our position it is high tide. When the moon is on either side of our position on Earth it will be low. Task Card #2: A spring tide happens when the Earth and moon and Sun are all in a line. A neap tide happens when the moon is at a 90 degree angle from the Earth and Sun. Task Card #3: The seasons happen on Earth because of the tilt of the axis. The Earth is tilted at 23.5 degrees. Sometimes one hemisphere gets more direct sunlight than the other hemisphere and that causes different seasons.

Seasons & Tides Answer Key Watch It! Task Card #2: A tide is the gradual rising and falling of the Earth s oceans caused by the moon s gravitational pull. Task Card #3: The moon s role is that the gravitational pull from the moon causes the tides to rise and fall on Earth as it revolves around our planet. Task Card #4: The tide that causes the highest and lowest tide is called the spring tide. The Earth, Moon, and Sun are all lined up in a straight line during the spring tide..
