  • SciGirls | Mother Nature's Shoes 01: Identify the Problem

    The SciGirls have identified the need for a better non-slip boot cover to wear in the winter. The first step in creating this new product is to look at the current technology and determine the pros and cons of those products. This step gives the SciGirls ideas about how to improve the current technology.

  • SciGirls | Mother Nature's Shoes 02: Research

    This SciGirls video highlights the research stage of engineering design as the girls look at how animals have adapted to get around on slippery surfaces. When creating a product inspiration can come from anywhere. For the SciGirls, inspiration for creating better non-slip winter shoes comes from animals. The girls do their research at two local zoos and observe mammals, reptiles, birds, and even insects to see how they have adapted to stay upright on slippery surfaces.

  • SciGirls | Mother Nature's Shoes 03: Test Materials

    This SciGirls video shows the girls collecting data on different household materials to see how much friction there is between them and a sheet of ice. Before building a prototype of a new product it is important to test your materials. In the process of creating non-slip boot covers, the girls need materials that will not slip on the ice. The collect data about the pounds of force it takes to move the materials across a sheet of ice to predict how the might behave when made into a boot cover.

  • SciGirls | Mother Nature's Shoes 04: Data Analysis

    This SciGirls video illustrates how girls can take data from an investigation and make conclusions based on the evidence. Critical thinking is an important skill to have in science, technology, engineering and math. This video is a great example of looking at data from a series of tests, organizing it in a meaningful way and then making conclusions based upon what the data is showing you.

  • SciGirls | Mother Nature's Shoes 05: Share and Test Prototypes

    This SciGirls video highlights the difficulties in testing prototypes and involving the public in testing. Failure is something that happens as part of the engineering design process. The SciGirls experience this firsthand when testing their first non-slip prototypes with friends and family. The girls problem solve to continue to get feedback from their participants.

  • SciGirls | Mother Nature's Shoes 06: Mentor Moment

    The SciGirls talk with their mentor about the struggles they had when testing their prototypes and get suggestions for next time. Seeing women who have succeeded in STEM helps inspire and motivate girls, especially when they can relate to these mentors as people with lives outside of the lab.

  • SciGirls | Insulation Station 01: Identify the Problem

    In this engineering design challenge, the SciGirls learn about the background and history of the project and learn about the constraints they have. It's important to know your constraints of supplies and time before starting a project.

  • SciGirls | Insulation Station 02: Research

    In this SciGirls segment, a group of girls and their mentor, a mechanical engineer, collect data on the condition of their ice shanty using an infrared camera to determine where the heat is escaping.

    Grades: 5-8
  • SciGirls | Insulation Station 03: Mentor Moment

    In this SciGirls segment, a group of girls team up with Shengyin Xu, a female architectural engineer and sustainability specialist, to learn about solar energy and insulation. This video emphasizes the importance of mentoring for young girls and women in STEM fields.

    Grades: 5-8
  • SciGirls | Insulation Station 04: Prototype Testing

    In this SciGirls segment, the girls take the advice of their mentor and build an ice shanty prototype. They run tests on energy transfer to determine which walls they should insulate, and run into some trouble when they realize that they changed too many variables in one of the tests and have to do it over again.

    Grades: 5-8
  • SciGirls | Insulation Station 05: Insulation Testing

    In this SciGirls segment, the girls decide what material to use for insulation. To figure it out, they run tests on a series of household materials, and choose the material which kept a cup of hot water the warmest within a set period of time.

  • SciGirls | Super Sleuths 01: Identify the Problem

    This SciGirls video demonstrates the beginning stage in investigating a crime scene. The SciGirls get called to a crime scene and have to figure out who committed the crime. They begin by learning about the stolen item and possible suspects.

    Grades: 5-8
  • SciGirls | Super Sleuths 02: Mentor Moment

    Girls benefit from relationships with mentors. Not only can mentors guide the girls through an inquiry investigation, but they also serve as role models, someone succeeding at a scientific career. As a lead crime scene investigator the mentor takes the girls through the detailed process of walking through a crime scene.

    Grades: 5-8
  • SciGirls | Super Sleuths 03: Collect Evidence

    This SciGirls video shows the girls working with their mentor to collect the evidence from the crime scene. There are lots of steps involved in collecting evidence from a crime scene to make sure there is no contamination. The SciGirls learn about the process from their mentor and then document and collect everything to take back to the lab.

    Grades: 5-8
  • SciGirls | Super Sleuths 04: Analyze Evidence

    This SciGirls video shows the girls analyzing some of the evidence collected from the crime scene. When processing evidence it's important to look at everything and make detailed observations without jumping to conclusions. The SciGirls examine suspect interviews, shoes, and handwriting samples to learn what they can about what might have happened at the crime scene.

    Grades: 5-8
  • SciGirls | Super Sleuths 05: Analyze

    This SciGirls video shows the girls working with a mentor to analyze some of their evidence using the same techniques that professionals use in the lab. The SciGirls must use their powers of observation to look for patterns as they use a microscope and other tools used in a professional lab to inspect some of the evidence found at the crime scene.

    Grades: 5-8
  • SciGirls | Super Sleuths 06: Shoeprint Analysis

    This SciGirls video shows the girls using their powers of observation to figure whose shoes left shoeprints at the crime scene. The SciGirls learn how to make comparisons between shoe prints found at a crime scene and suspects shoes. They make prints and then copy them onto transparencies so that they can see to make precise observations.

  • SciGirls | No-Slip Grip

    Predict the amount of friction different surfaces will create with this SciGirls activity. Friction is a force that resists motion when two objects are in contact. If you look closely at the microscopic surfaces of all objects, there are tiny bumps and ridges. When you try to slide one object over another using just a small amount of force, the object won't move since those tiny bumps and ridges catch onto another. This is called static friction. If you apply a little more force, the object will "break free" and slide, although you still need to apply force to keep the object in motion.

  • SciGirls | Insulation Station

    Insulation in the home is used for different purposes in different parts of the country. In warmer climates, insulation keeps the cool air in and the hot air out; in cooler climates it has the opposite effect. The purpose of insulation is to slow down the conduction of heat from one side of a wall to the other.

  • SciGirls | House Warming

    Today, some house builders are using passive solar design to increase energy efficiency. The key is to use the sun's heat to warm a house in the winter, and to avoid the sun's heat in the summer to keep the house cool. In this activity, girls will test paperboard models of different building designs to discover how the design affects the amount of heat that enters the house.
