2 Kesler Science Station Lab Gravity If you have never used my Kesler 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 at chris@keslerscience.com. I cannot guarantee that all resources will be available, but I tried to choose ones that have been around for many years.

3 Kesler Science Station Lab Gravity Teacher Directions Explore It! I will spend much of my time at this station making sure that the students are doing the gravity arrows correctly. The weight activity is in a separate file in the zipped file you purchased. You will need to set out some calculators as well unless you want your students practicing the math. Illustrate It! You will need to set out colored pencil and markers at this station. Read It! Print several different copies (I use 6) of the reading passage so that multiple students can read at different paces. 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/baggies for kids to pull from. This is also 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!

The video is on YouTube and my Google drive. Use YouTube unless your school is blocked. The original link is Note that both URL s are case-sensitive. Assess It! Students should be encouraged to do the Research and Explore station before attempting this one. If I grade anything I usually take a close look at the answers from this station.

9 Gravity Gravity has been around since the very beginning of the universe, and it works the same way everywhere in the universe, on all kinds of different objects, of all different sizes (larger than atoms - those are held together by atomic forces instead). The bigger an object is, and the closer you are to it, the stronger its gravitational pull is. In the very beginning of the universe, after the Big Bang, gravity pulled atoms together to make stars and planets. Once the stars and planets had formed, gravity kept the planets in orbit around the stars, and moons orbiting around the planets. On each planet that is large enough, gravity even keeps an atmosphere around the planet. On Earth, gravity keeps the air around us (and everything else) from drifting off into space. Gravity also causes things to fall to the ground, and causes the ocean's tides, and causes hot air to rise while colder air falls (which in turn causes wind). Nobody fully understands how gravity works, or even why gravity exists. One way of looking at gravity is to think of it not as a force like magnetism, but instead as a natural result of the way mass bends space. Any object with mass (like a star) pushes on space and bends it, so that other objects (like planets) that are moving in a straight line are also going around the star. It looks to us like the star is pulling on the planet, but really the star is bending space. One of the most famous scientists to discuss gravity is Isaac Newton. Although it has been told over and over that he discovered gravity after being hit in the head by a falling apple, it is now believed this story is somewhat unlikely.

Einstein B. Degrasse Tyson C. Newton D. Galileo Which famous scientist first began discussing gravity? Another title for this passage could be? A. How Gravity Changes the Tides B. The Sun s Gravitational Impact C. Newton and Gravity D. Gravity A Quick Summary of This Powerful Force

16 Use the map of the solar system to perform the following activities. 1. Use one of the arrows to show the direction the Sun s gravity is pulling on the Earth. 2. Use the other arrow to show the direction Earth s inertia if the Sun s gravity did not exist. The line circular line around the Sun represents the Earth s orbit and how the Earth travels around the Sun due to the Suns gravity and the Earth s inertia. They balance each other out and put the Earth and other planets into a stable orbit around the Sun. The Earth s orbit is considered a balanced force.

27 Gravity Answer Key Explore It! Sun s Gravity Earth s Inertia Write It! Task Card #1: The Earth orbits the Sun because the Sun s gravity pulls on it. However, the moon is very close to the Earth and it orbits the moon because the gravity from Earth is stronger than the gravity from the Sun at that distance. Task Card #2: The larger an object is the more gravitational force it will have. More mass = more gravity Task Card #3: The Sun s orbit wants to pull the Earth towards the Sun, but the Earth s inertia wants to send the Earth out into space. These forces balanced each other out and allow the Earth to safely orbit around the Sun.

29 Gravity Answer Key Watch It! Task Card #2: 1. Nebula Task Card #2 1. Stardust and gravity Task Card #3 1. The solar system was started in a nebula. Spiraling discs of dust (star dust) where held together by gravity while the Sun was being formed in the middle of everything. The Sun began the process of nuclear fusion and the electromagnetic waves eventually blew away the remainder of the dust to beyond the edge of our solar system. The 8 planets that formed were too large to be blown away by solar wind and are now held in place by the gravity of the Sun.
