Welcome to 7th grade Science class with Mrs. Kramer! Make it a habit to check this page often to see what we've been doing in science, what you may have missed if you were absent, and as a resource for your middle school science class.
 * 9-3-13 Tues**

Emergency procedures, classroom policies, and my Complete your "All About Me" for tomorrow.

Following Directions and Lab Safety with the Bikini bottoms gang!
 * 9-6-13 Fri**

We finished our discussion of Lab Safety. If you would like to watch the video about what NOT to do, you can go here! [|7th Grade Science Safety]. If you would like to review the power point about metric length, you can do that as well.

An interactive metric measurement tutorial: [|Metric Measurement Tutorial]
 * 10-1-13 Tues**

Density is a measure of the amount of matter in a given space, and is calculated like this: densisty = mass/volume (mass divided by volume). The correct label for density is g/cm3 (read "grams per cubic centimeter"). Starting today you will calculate the density of water, wood, and rock. Why do things sink or float?

When you make a hypothesis, you are making a statement. It is your prediction about what you think the answer to your question or the outcome of your experiment will be. It is your best educated guess. Today's homework:
 * 10-21-13 Mon**

A controlled experiment means that you have changed only one thing in your experiment. That is your manipulated variable (also called the independent variable). The thing that you are measuring or observing is the responding variable (dependent variable). All other variables need to be controlled (kept as much the same as you can). The control group serves as your standard for comparison. Today's homework: This is your practice at identifying the controls and variables in a scientific experiment. This assignment is for a grade:.
 * 10-22-13 Tues**

When you interpret data you are looking for meaning and trends in that data. Here is today's homework: THERE WILL BE A QUIZ TOMORROW ON SCIENTIFIC METHOD VOCABULARY.
 * 10-23-13 Wed**

More practice recognizing controls and variables in a scientific investigation. We will practice drawing valid conclusions that directly address the hypothesis.
 * 10-24-13 Thur**

Today we have an opportunity to use the scientific method in a virtual lab setting. Click on this link [|Scientific Method Virtual Lab] and follow the directions found on your lab sheet. If you need another copy of the lab, here it is. **PLEASE TAKE THE TIME TO READ AND FOLLOW ALL DIRECTIONS. I WILL BE LOOKING FOR THE USE OF GOOD SCIENTIFIC METHOD** **VOCABULARY!!**
 * 10-25-13 Fri**

You should have worked hard to finish the Scientific Method Virtual lab today. Due for tomorrow, more practice with

__**SKILLS RECOVERY PROGRAM** **1ST QUARTER**__ During the second half of the quarter, we studied the scientific method. To further your understanding of that process, you will complete the website found here: [|Please Teach Us the Scientific Method]. You will be looking at the Introduction page. Read through this page in it's entirety. When done, click on the next bullet on the task bar at the left, "Task". then read that page completely. PLEASE NOTE THAT YOU WILL **NOT** BE WORKING IN TEAMS. THIS IS DONE INDIVIDUALLY! Continue to the "Process" page and read these directions. You will be prompted to print off certain pages that you need to complete will working through the webquest. FOLLOW ALL DIRECTIONS IN ORDER. It's that simple. When you are done, you will create a powerpoint (a good, readable one, that can be printed for me to see).


 * If you have any questions, your SRP teacher should be able to help you. If not, see me during the day.

Instead of moving forward in the book with our discussion of Plate Tectonics, I wanted to take the opportunity today to let you listen a little more to Dr. Robert Ballard. If you recall, we heard him tell of his discovery of deep ocean hydrothermal vents that are home to a host of strange creatures. In this "Ted Talks video", you will hear Dr. Ballard speak passionately about furthering the cause of ocean exploration. **[|Robert Ballard: Exploring the Oceans Hidden Worlds]**
 * __11-19-13 Tues__**

You have class time today to read in your book, pages 32-35. When you feel you are ready, quiz yourself on your knowledge of sea-floor spreading here: **[|Sea-Floor Spreading Quiz].** You will also have time in class to work on "The Theory of Plate Tectonics Guided Reading". This is due FRIDAY.
 * __11-20-13 Wed__**

To help you prepare for your test, visit this website ** [|The Dynamic Earth] **and follow the prompts to help you fill in the worksheet as you **__READ__** through the pages.
 * __11-22-13 Fri__**
 * THE TEST ON PLATE TECTONICS WILL BE ON __TUESDAY__!**

Today we begin our discussion of ways in which we use mineral resources. You will need to visit the Earth Science sections of the Kid Zone to find the answers to **the questions on** the "Mineral Mania" worksheet. Click here: **[|Rocks and Minerals]**
 * __1-29-14 Wed__**


 * __1-31-14 Thur__**
 * If you get done with the "Mineral Mania"and still have time to spare (AND if you are all caught up on your homework) you can give this activity a try: [|Rocks and Soils]**


 * __2-4-14 Tues__**
 * Today you will make your own Mineral Hardness scale based on the results of your hardness tests performed here: [|Hardness Testing Lab]. Follow the directions given by me as well as what's on your handout [[file:Moh's Virtual Hardness Lab.PDF]] to put 10 unknown minerals in the proper order of hardness, from softest to hardest.**


 * __2-5-14 Wed__**
 * Click here for the link that will take you to today's lab: [|Virtual Mineral Identification] This is the accompanying lab sheet: [[file:Virtual Mineral Lab Report.PDF]]**

__**2-8-14???**__ You will be working on identifying unknown minerals over the next few days. This is the lab you will follow and complete.

 * __3-19-14 Wed__**
 * What is the Geologic Time Scale? How do scientists make sense of all that has happened on Earth in it's long history? We start discovering the answers to those questions and more today. First, we'll see what you already know using this pre-assessment: [[file:Geo. Time Scale Questionnaire.PDF]]**


 * This is the activity that we will use to help us discover geologic time: [[file:Making a Geologic Time Line.PDF]]**


 * Here is a link to some examples of what a geologic time scale can look like: [|Images for Geologic Time Scales]**


 * __3-25-14 Tues__**
 * Digging deeper into geologic time, today you will start a webquest that will provide you with information that builds on what you discovered after completing your Geologic Time Scale. Click here:[|"Geologic Time"].**


 * Just in case you lose yours, here is where you can get a copy of the "Geologic Time Webquest" [[file:Geologic Time Webquest.PDF]]**


 * __3-31-14 Mon__**
 * How do we know about what lived on Earth before we did? The clues are found in the fossil record. We uncover those clues by exploring [|"Getting Into the Fossil Record"]. To guide your exploration, use the [[file:Getting Into Fossil Rec Scavenger Hunt.PDF]]**


 * __4-3-14 Thur__**
 * Visit this website, [|"Stories from the Fossil Record"] to guide you as you complete your "Evidence Chart". Discover how much we can learn from the fossil record.**


 * Remember to check in periodically with the [|Paleontology Lab] at John Day National Monument. Maybe you'll get to see them in action!**
