This experiment is used to decipher which of the three types of erosion causes the greatest change. After setting up dirt or soil on one side of three separate pans, designate one pan for water erosion, one pan for wind erosion, and one pan for glacial erosion. Then, once a day for three days, spray the water five times on the dirt in the water pan, use a straw to blow on the dirt in the wind pan five times, and slide a piece of ice on the dirt in the glacial pan five times. Have students keep a daily record of their observations and predictions. I chose this experiment because I thought it would be a great way to bring the "real world" into my classroom. It is also an excellent opportunity for students to use their scientific skills by recording their theories. I would use this experiment during a unit on erosion and Earth Systems.

This activity is used in conjunction with a field trip to the zoo. Before going on the trip, students are given a clipboard with pictures of different animals on them. Once arriving at the zoo, the students are responsible for locating each animal on the list. I chose this activity because I believe that all field trips should be executed with a specific purpose in mind. This scavenger hunt provides structure and classroom connection to the trip. I also chose it because it can be modified depending on the grade level. For older students, the pictures can be replaced with specific animal facts or attributes. I would use this activity when going on a field trip to the zoo or aquarium, making sure that the animals presented on the list were ones that had been previously studied in class.

This activity shows students how certain animals stay warm in the winter by providing a life-like representation of the effects blubber. A zip-lock baggy containing Crisco is placed into a bucket of ice water. Students then place their hand into the baggy and note the temperature. I chose this activity because it provides an actual representation of how animals stay warm in the winter that students would likely remember in the future. If the lesson is properly constructed, this activity also encourages critical thinking, making predictions, and discussing observations. When using this activity in my classroom, I would first discuss various polar animals with my students, making sure to ask them their opinion on how the animals manage to stay warm. This would then lead to a discussion on how humans stay warm. After creating a list of various ways in which humans adapt to cold weather, I would conduct the "blubber" activity. I would then explain to students that polar animals have an extra layer of fat, called blubber, to keep them warm. As a class, we would then discuss how certain human adaptations mimic the polar animals' survival techniques.

This lesson involves using balloons to explain the difference between a solid, liquid, and gas. Before beginning the lesson, the teacher needs to have three identical balloons--one filled with a gas, one filled with a liquid, and one filled with a solid. Students would then be allowed to explore and compare certain traits of the different balloons such as weight, texture, and fragility. After exploring these many differences with students, the teacher could then explain to them the properties of a solid, a liquid, and a gas. This activity caught my attention because it was a cheap, easy, hands-on way for students to actively explore the differences between a solid, liquid, and gas. I would use this activity as a catchy introduction to a lesson on matter. (Although the creator of this activity used it for his/her preschool-aged children, I believe that it can be a great tool for the elementary classroom as well.)

"Monster Physics" is an app that allows the user to create and test his/her own machine using a variety of devices such as wheels, propellers, ropes, etc. After the user invents a machine, he/she is able to test it to see if it works. So, not only does this app allow students to create their own system, but it allows them to evaluate the effectiveness of their creation as well. I chose this app because it looks child-friendly and can easily be used for students to explore different mechanisms that I may not have readily available. Also, this app lets them create a device which may require too much time or space if attempted within the classroom. I would allow students to use this app during a rotation time or if they finish their assignment early in order to further their knowledge of mechanical systems as well as enhance their critical thinking skills.

In this game, students are separated into teams. Each team is given a block of Legos. Students must then take turns crab-walking from one side of the room to the other. Once the student reaches the other side, they are to break off one Lego from their block, set it on the floor, then pass the remaining piece to the next classmate in line. This game is a fun and easy way of explaining the process of the weathering away of a rock through the effects of erosion and deposition. I chose this resource because I thought it was a great way for students to become actively involved in the process of erosion, while allowing them to be active and work with their classmates. I would use this game in my classroom as a conclusion to a lesson on weathering, erosion, and deposition.

In this activity, students are put into small groups to construct 3D candy landform maps. To begin, students are given a blank outline of the United States on a large piece of paper and a landform map. Students must then map out where all of the major rivers, deserts, mountain ranges, plains, and oceans are. Next, students are given various candy, yarn, and paint with which to construct their map and key. I chose this activity for three main reasons. For one, it allows students to work with their peers to create a product. It also provides them with a link between social studies and science. Finally, students are very likely to be engaged in the project because both candy and painting are involved. I could see myself using this project in my classroom as a conclusion to a unit on landforms because it is a culmination of many different types of landforms as well as an application of what has been studied to an actual map of the United States, thus making a real-world connection.

This is an activity in which students use slices of bread to create replicas of various landforms. After introducing the varying types of landforms to the class, the teacher will provide students with slices of bread with which they can create different land types (such as islands, peninsulas, gulfs, straits, and isthmuses) in a hands-on, memorable manner. After the students have created the landforms, they can glue them to a piece of paper, or simply eat them as a snack! This activity caught my eye because I feel as though it would be engaging for the entire class. I also thought it was cost-effective and simple to execute. This activity would be an excellent way to introduce a unit on landforms because it gives the students a chance to become acquainted with the topic in an appealing, memorable way.
