- Each group will be responsible for a class presentation on their assigned topic, where they will explain whom the scientist was, what led the scientists to perform the experiment, describe what the experiment consisted of in detail, and the findings and later contributions of the experiment to the atomic structure of he atom.
- Each group will also be responsible for constructing a model that illustrates their presentation.
Group 1: J.J. Thomson’s experiments with cathode ray tubes.
Group 2: Ernest Rutherford’s gold foil experiment.
Group 3: The Rutherford experiment by Hans Geiger and Ernest Marsden that resulted in the discovery of the atomic nucleus.
Group 4: James Chadwick’s discovery of the neutron.
Group 5: Types of radiation ( Alpha, gamma, and beta)
Each group will have a class presentation explaining the assigned concepts and illustrating these with a habitat/ecosystem illustration which will be used by the group to explain the relationships and inter dependence present.
Group 1: Biodiversity, ecosystem, environment, keystone species
Group 2: Biomes, ecosystems, communities, population, individuals
Group 3: Food webs, types of producers, types of consumers,
Group 4: Aquatic and Terrestrial biomes, Abiotic and biotic factors.
Group 5: Types of niche, species that affect niches, edge effect on populations.
Using the following concepts each group will create an images only presentation. Each image will be utilized to explain each concept and answer questions in class. Keep in mind that for several concepts you can use only one image.
- Frame of reference
- Positive displacement
- Negative displacement
- Average velocity
- Instantaneous velocity
Group 1: Dwarf planets and exo planets.
Group 2: Meteors, Meteoroids, and meteorites.
Group 3: Comets
Group 4: Asteroids.
Each group will bring a presentation that explains what each concept is, its structure/composition and where its found in or out of our solar system. Each group will also provide a brief fictional story that illustrates the properties of their assigned interstellar body as a fictional character.
For this month’s project you will be working in pairs and/or groups of three. Each pair and/or group will need to complete a chart of three different molecules, just like the one we completed in class plus a model of one of the molecules.
I will be assigning the molecular models in class to each group.
DUE DATE: Wednesday March 8th
For this month our project will require understanding of the cconcept we’ve been studying and also great creativity.
Your group projects must include the following:
- 15 spaces or blocks on your display.
- 4 or more trends among the 15 spaces or blocks.
- Index cards or small squares of paper that explain the periodicity of your display.
- Group oral presentation.
Here are the instructions for this month’s project.
- Research: Internet sites, magazines, and/or pages 18-24 of your textbook. Use the researched information to explain how populations cause problems to Earth’s environment. * No less than 2 paragraphs.
- Choose a current environmental problem/situation of your interest. Explain what it consists of and how humans are the cause of it. * No less than 2 paragraphs.
- Group work: Make a presentation that illustrates each group member’s environmental issue/problem. Apply the steps of the scientific method and propose an informed or educated solution for each problem.
- Due date: Wednesday 9/28/2016
