Cancer and the Cell Cycle
Identify the phase of the cell cycle when looking at diagrams of cells or cells in different phases. Analyze the cell cycle and explain the major events that occur within the cell during the cell cycle. Explain the control or preventative mechanisms in cells that prevent cancer from occurring.Explorer Probe
Elements and compounds have unique physical and chemical properties.Using Momentum and Impulse to Prevent Injury
Students apply momentum and impulse concepts to real-world safety devices that protect people and property during collisions. Students will calculate the momentum and momentum change (impulse) of an object of their choosing during a collision. Students will also describe how safety devices (such as airbags, seatbelts, bumpers, crash barriers, etc.) reduce forces by lengthening the duration over which a collision occurs.DINO Project
After completing this lesson, students will be able to demonstrate the importance of rock, fossil and prehistoric evidence in determining geological timelines.Scientist Lesson
The students will have to identify how the advances brought on by these scientists have changed society for better or worse. They can successfully convey to their peers why the contributions from their scientist/inventor is either helpful or harmful to society. They will have to be able to do this using the technology provided.Watershed
Students will demonstrate an understanding of the size of the watershed areas are for our water district, and how the actions of citizens in the area can affect the quality and supply of water.A Trip Around the Solar System
After students investigate the eight planets, research their characteristics and examine their distance from the sun, etc., they will construct a model of one of the planets and put together a PowerPoint presentation. After the group presentations, they will attempt to create a planet that will sustain life by choosing the proper combination of characteristics on an interactive activity on a NASA sponsored web site.Christmas Cookie Caper
Students will be required to meet several criteria to demonstrate their mastery of the concepts of this lesson. They will have to complete their laboratory tests in a safe manner. They will record the results, in detail, in an organized manner in their own data tables. They will compare test observations of their known pure samples to the observed test observations of known pure samples. Through discussion with their laboratory partners about their data comparisons, each laboratory group will then attempt to identify the three unknown powders making up each of the three unknown Mystery Mixtures. They will have to be able to explain, in writing, the rationale behind their substance identifications. A correct identification of all 3 separate powders making up 2 of the 3 mixtures will be considered a success.Diffusion with Gummy Bears
Diffusion is the movement of materials from an area of high concentration to an area of low concentration. This is generally a difficult concept to see as it happens on the molecular level. After learning the terminology for cell transport students can then apply the content knowledge to how polymers such as gummy bears interact with solutions. In this lab, students will measure the movement of water by measuring the change in size of a gummy bear.All About Shadows
In this unit, students will learn what the three things necessary to produce a shadow are, how the Sun's position in the sky changes the length and positions of shadows, and be able to describe the changes in length and position of shadows from morning to midday to afternoon.
