Assignment "Element Tiles"

To review the Elements and all the information that surrounds them we are going to make "Element Tiles". You will be given a hand out in class that has all the needed information and how you will be graded. You will be given time to research for this information on Friday. You will need to complete this activity by NOVEMBER 12th.

Paper will be provided, if you don't have some at home. I don't want to hinder your creativity by giving you one color or one type of paper.

Here are the resources I want you to check out when collecting your data for your tile.

25 Most Common Elements

On Monday, November 9th, we will have a quiz over the 25 most common elements. On this quiz you will either be given the element symbol or the name of the element. You will be responsible for telling me the symbol or the element or both. I have provided you with the following activities to practice with and you will be making flashcards in class. SPELLING and CAPITALIZATION DOES COUNT!

On Friday, November 6th, you will have the opportunity to take a pretest. If you get 100% on the pretest, you will not have to take the test on Monday. Study up!

How fast is YOUR reaction time?

Hitting a fastball in Major League Baseball is one of the hardest things to do. How fast is your reaction time? We are going to practice and see how fast our reaction times are.

Fastball Reaction Time Simulator


Can you hit a major league fastball? First, lets see if your reaction time is fast enough!

Practice a few times, then find your average reaction time on three pitches. Post your time and write a comment.

8th Grade Science Safety Posters

Each person will create a poster that illustrates a different lab safety issue. You should finish working on your posters during class. Monday you will briefly explain your safety issue to the rest of the class.


Guidelines
• No more than 12 words
• Clearly shows the safety issue assigned
• Easy to understand the issue
• Looks good
• School appropriate
• Grabs your attention
• Catchy slogan
• Colorful design
• Neatness
• Name written only on the back of the poster


You will be graded by the rubric handed out in class.

A picture of each poster will be posted on our blog.
