Subject: Credit Recovery Science (8), or Science (8)
Title: Big Science of the Small World of Atom
Description: This module provides 8th grade middle school students a basic understanding of the atomic structure. With the knowledge evolution of the atom structure, modern sciences and technologies, particularly nanoscience and nanotechnology, have been revolutionarily advanced. In this module development the structure of an atom and its constituents will be demonstrated with the help of the 3D visualization and hands-on activities.

Title: The Need for Speed
Description: After viewing an introductory illustrated podcast on speed, distance, time, and velocity, students explore distance-time graphs using interactive websites. Working in cooperative learning groups, students will investigate the motion of toy pull-back racers and collect data to analyze the speed of the cars between various positions marked on the race track. Students will use the data to create graphs, analyze data and present findings to the class.

Title: Mentos, Soda, and Nucleation
Description: In this lesson, Mentos candy and different types of soda are used to show examples of nucleation, surface tension, surface area, polar attractions, and supersaturated materials. A video will be used to show the examples and the students will then work in groups to determine what their hypothesis is about what is happening and why. The students will be given a chance to debate with other students about why their hypothesis is correct. This lesson could be used in eighth grade physical science, physical science, chemistry, and/or physics.

Title: Genetic Babies
Description: Students will explore Gregor Mendel's laws of genetics in this lesson. Students will be paired in male and female groups. If girls and boys can't be evenly divided, same sex students can be paired to represent research scientists. Different candy will represent alleles for various characteristics. Students will combine dominant and recessive traits to determine the phenotype and genotype of their genetic babies. The genetic baby will be designed and displayed for peers to view.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMS-U Project.

Title: Exploring Linear Data
Description: In this lesson, from Illuminations, students model linear data in a variety of settings. Students can work alone or in small groups to construct scatterplots, interpret data points and trends, and investigate the notion of line of best fit.

Title: What's in a Graph?
Description: The purpose of this Science NetLinks lesson is to help students understand data tables and graphs. They explore the guidelines for making tables and graphs and learn how to interpret graphs and determine which graph is best suited for the data.

Title: Exploring Pendulums
Description: In this Science NetLinks lesson, students explore Web sites with simulations of pendulums, where they are able to change the length and angle of the bob and observe its effects. They then construct and test their own controlled-falling systems, or pendulums, to further observe and verify these theories. This lesson helps students understand concepts related to how gravitational forces act on objects by exploring the motion of pendulums.

Subject: Science - Physical Sciences - Social Studies - Geography
Title: Liquid Density and Oil Spills
Description: In this lesson, from Xpeditions, students conduct a simple experiment demonstrating the variable densities of corn syrup, water, glycerin, and vegetable oil. Students then transfer this concept to an examination of cleanup methods used in the Exxon Valdez oil spill. They conclude by writing paragraphs hypothesizing what would happen during an oil spill if oil and water were the same density and therefore mixed together easily.

Subject: Science
Title: Snow Goggles
Description: The aim of this lesson, from Science NetLinks, is to illustrate how the scientific method can be used to solve different kinds of problems. As part of this lesson, students build snow goggles similar to those used by the Inuit peoples. Students also create their own version of the goggles to improve upon existing designs and compare the process used to invent snow goggles with that employed by designers of the MESSENGER spacecraft.

The Scientific Method
Overview:
This podcast was created by a GEMS-U team using the lesson plan "Toilet Paper Strength".  The girls in the video demonstrate the scientific method by testing various brands of toilet paper.  They begin by discussing the steps in the scientific method.  Then, to review each step, the girls use the experiment described in the lesson plan using pennies, water, and samples of toilet paper.  Through this simple video, other students can see a simple version of the scientific method.

Dauphin Island Sea Lab Field Trip
Overview:
This podcast gives a brief overview of our field trip to the Dauphin Island Sea Lab.  This incredible weekend excursion provided 35 8th grade science club students a chance to explore a barrier island, view marine life hands-on, and study ecological and evironmental elements of the Gulf of Mexico.  The students participated in several activities such as trip to the local estuarium, a boat trip on the sea lab research vessel, a salt marsh trip, shark dissection, and a plankton study.  The students learned a tremendous amount about the Gulf of Mexico and Dauphin Island.  The trip was amazing and the students still talk about it today!

Einstein Demonstrations- Photo-Electric Effect in Action
Overview:
The understanding that light interacts with matter like a particle also lead to modern information technology, like computers, TVs, and lasers. The communicator is a direct example of the Photo-Electric Effect, one of Einstein’s groundbreaking 1905 theses. This is the achievement for which he won the Noble Prize for Physics in 1921. The Photo-Electric Effect centers on the ability of light to free up electrons inside metal atoms. This induces electric current through out an illuminated piece of metal. The idea that light can physically disturb electrons denotes a particle nature of light. The energy produced is proportional to the frequency of light, not the intensity of light. This fact draws on the wave-like properties of light within the same interaction.
