Grade+9+Chemistry

Chemical Reactions
In Chemistry students were studying the different types of chemical reactions. The students working in groups created their own investigation. They focused on factors like changes in the speed which the chemical reaction occurs, how much heat energy is produced, and what products are created. These changes can be made with slight alterations in the reactants, such as diluting an aqueous reactant, changing the initial temperature, or increasing/decreasing the surface area of a solid reactant.

When a scientist publishes a piece of research, the research is always peer reviewed. When the report is completed go to the page of one project (not your own) and click on the peer review link. Write a short review of the research. The review can be in the form of a comment or question and should identify strengths and/or offer suggestions for improvement. Use the science report writing rubric to help you identify the specific details. The review should only focus on the nature of the scientific research and the design and technical quality. An example of a strength could be: //“The research question clearly identified the dependent and independent variables”// An example of a suggestion for improvement could be: //“The results suggested that there were some experimental errors but the evaluation did not discuss the sources of these”//

Digital Stories
Some students presented their research using a digital story.
