Space Debris

-
Objective: Students will learn about the problem of space debris and design and build a prototype of a space debris removal system or tool.
Grade: 6th
Length: 2 class periods


Lesson Development Process

1. Study the science curriculum: There is a sixth grade astronomy unit at the beginning of the school year.  Standards related to this problem are: 
SCI.G6.8.c. The role of gravity
SCI.G6.8.d. Revolution and rotation
SCI.G6.8.i The history and technology of space exploration
SCI.G6.1.i Models and simulations are designed and used to illustrate and explain phenomena and systems

2. Research the real-world problem: This problem affects all people on Earth.  There are more than 500,000 human-made objects orbiting our planet.  Space debris can collide with satellites, spacecraft, etc., resulting in more space debris.  Scientists and engineers are working on solutions to clean up space debris.  The image above and a short video clip (https://scroll.in/video/871029/video-heres-why-you-dont-see-space-debris-in-satellite-images) will serve as a hook at the beginning of the lesson.

3. Brainstorm engineering solutions to problem: Students will work in groups to research methods for clean-up being tested by scientists and engineers.  After conducting research, students will design and build a prototype of a space debris removal system or tool.  Students can use an established design as inspiration or come up with a unique idea.  Students will test their prototypes in the classroom to see if they are able to retrieve or knock a piece of "space debris" safely out of orbit.

4. Incorporate technology: Students will use iPads to research current methods for dealing with space debris.  Videos and directions will be projected on an interactive whiteboard in the classroom.

5. Look for correlated math standards: Students will analyze statistical information from an infographic about space debris.  Students will apply knowledge of velocity and speed as they compare the speed of space debris in low-Earth orbit to the speed of sound and the average speed of a car traveling on the highway.

6. Allow for creativity: Because this lesson is for sixth grade, students will have freedom of choice in materials.  If they choose to, students will have the opportunity to add personal or artistic touches to their prototypes.

The Deer Population Problem in Fairfax County

-
Image
Objective: To learn why the overpopulation of deer can lead to problems within an ecosystem and what strategies are being used by county officials to address this problem. Grade: 4th Length: 2 class periods Lesson Development Process 1. Study the science curriculum: Fourth grade students are starting a unit on Virginia Ecosystems.  Standards related to the local problem of the overpopulation of deer are: SCI.G4.5.b Organization of populations, communities, and ecosystems and how they interrelate SCI.G4.5.f Influences of human activity on ecosystems 2. Research the real-world problem: There is an overpopulation of deer in Fairfax County, VA.  When there are too many deer in one area, ecosystems and humans may be affected.  Without a natural balance in an ecosystem, humans must devise strategies for fixing the problem. 3. Brainstorm engineering solutions to problem: Students will read a county report on the deer population problem.  The te...

From Science to STEAM

-
You might be wondering, why would educators switch from teaching science to teaching STEAM?  Traditionally, science  classes were taught in isolation and not integrated with other subjects.  This is a compartmentalized way of learning that leaves students with a fragmented view of curriculum (Fogarty, 1992).  There are many benefits of integrated STEAM (science, technology, engineering, art, and math) curriculum, including: - Learning that is more meaningful and relevant for students (Kubat & Guray, 2018). - Opportunities for students to develop problem-solving skills as they explore real-world problems from different perspectives (Kubat & Guray, 2018). - A student-centered model that promotes ownership, teamwork, inquiry, and connections among disciplines and to the real-world (Zhbanova, Rule, Montgomery, & Nielsen, 2010). - Students display higher levels of thinking and acquire more content knowledge when engaged in integrative curriculum (Becker ...
