7th Period - Chemistry-Room 210 - Mr. Rajski - 1st Semester Assignments

Directions: During our investigation we used several processes to try and make our experiment as successful as possible. Using observations and the linked simulations: analyze and explain the purpose of each process that we used to better understand how and why chemical reactions occur.

Read the introduction and procedure attached. Use the information to answer the questions and model the procedure in the Planning Section below.

Data Analysis: Write a paragraph that explains each part: 
What happened during your experiment? 
How would you explain the result of your experimental question?
What kind of claims can you make about the reaction that occurred?
What kind of claims can you make about the variables that you tested?
For EXTRA CREDIT: Compare and Contrast your analysis and the analysis of another group. Leave a comment explaining what you noticed.

You received a paper copy of this assignment in class:


Objective: You will be able to read and model chemical reactionsInstructions: Using your critical thinking skills, complete the molecular models and chemical reaction models to be able to identify the parts of a chemical equation.

Copies of this assignment were passed out in class.

Using your critical thinking skills, complete the molecular models and chemical reaction models to be able to identify the parts of a chemical equation.

Use this checklist to help you choose an experimental question, identify variables, and improve your procedures for your investigation.

Iron is cheap and strong and the most used metal in the world. The method of using carbon to reduce iron oxide to iron was very probably discovered accidentally in prehistoric camp fires. Here, charcoal would have been the source of carbon. The iron was used to make tools and weapons and gave its name to the Iron Age which started around 1200 B.C. - 600 B.C. Steel is a well known commonly used alloy made of iron and a small amount of carbon. Steel can be 1,000 times stronger than iron. Iron has a large number of different uses such as in Machines, Vehicles, and building structures.

To help you connect what we are learning in class to our communities - complete the following task below:


Something Beautiful - Something Ugly
Take 2 photos of your community. One photo of something that you consider beautiful in your community and something else that you consider ugly. Upload the pictures to Google Classroom.

Make initial observations and create an idea board to brainstorm ideas about our unit phenomenon.

Rate your group members on how supportive they were on this review assignment.

Winter is coming!!! Weatherproofing your home is important because it will help to save money on Energy Bills and protect your home from accidents such as frozen or bursting pipes. 


Determine how much energy it takes to heat up your home and then compare different materials to upgrade the insulation of your walls


Everyone will see things differently, and that’s OK. Just keep talking until you find the connections that stick. As you discuss your ideas, use our guided notes to find supporting evidence for why you think your connections are strong ones.
Each hexagon can connect to up to six others. Arrange and rearrange until you feel you have the strongest hexagon web in place that you can. Then begin explaining your connections with connection arrows, writing in why you have created intersections between key hexagons.

It's a party! You were asked to buy soda for a get together with some friends. You are at the store and they only have soda that is at room temperature. You need to decide what kind of containers would cool down soda in the refrigerator the fastest. Aluminum Cans or Plastic Bottles? 


Specific Heat Capacity of Aluminum: 0.897 J/gC
Specific Heat Capacity of Plastic: 1.10 J/gC


Using what you know about Heat Capacity. Which containers of soda would you choose? Explain Why.

Objectives:
Use models to illustrate that energy at the macroscopic scale is accounted for by the movement and position of particles. 
Investigate the effect of attraction forces on the phases and characteristics of substances.
Instructions:
Use the simulations on the slides to make observations and then conclusions about how Attractive Forces influence particles.

Instructions: Use what you understand about how energy is transferred from different objects to determine the specific heat of the metal substances that we were investigating during our experiment. 

Learning Objectives: 
Be able to describe the relationship between energy and temperature.
Be able to describe in words and pictures how energy is transferred between two objects at different temperatures and explain when and why this process stops. 
Be able to plan an investigation to produce data to support a model of how the system of a hot object and a cold object will change with time.

Instructions: Follow the link to the Guided Notes and complete the questions below.

Use the attached checklist to create a model explaining what you think happened with the ice melting differently on the blocks. 

Include both drawings and a written explanation.

Investigate how ice melts differently on surfaces or Aluminum and Plastic. Complete Parts 1 - 3 in the handout by watching the video or performing the experiment in class.

Use the attached animations to complete a set of guided notes about particles and their interactions.

Instructions: Complete the model below to show how energy from the sun is distributed on our planet.

Please complete and turn in the Safety Contract with contact information and have a 1in Binder by next week.

Instructions: Use the evidence below to propose an explanation for what happened to the Ancestral Pueblo people that lived in the Mesa Verde and Chacko Canyon regions.

Create a profile about yourself using the template attached. You may edit the slides in this attachment.
