Finding the Mass, Volume, and Density of Water Lab (Google Sheets)

Materials:

Goals

  • Students will practice their measurement skills using a graduated cylinder to determine volume and a triple beam balance to determine mass.
  • Students will determine the density of water by completing 10 trails and finding an average.

I use this lab to tie their measuring skills together and introduce the concept of density. We then do further explorations of density and practice using the formula.

This lab is a modified version of the lab posted at Middle School Chemistry – for further details about the lesson, please click on this link.

Prompt Notebook Paper (Prompt Template pdf) – print 20 sheets double sided and place into 3 prong poly-folder, add more pages as needed

I start each class with a science prompt – which was assigned for homework the night before. On Monday, I post the prompts for the week and students are able to work on them for homework instead of the start of class. They can do more than one each night, but we only go over one each class.  I found this to be a much better use of class time and started each class with a 5 minute review of skills and content.

When students come in, they come to my desk for the ‘stamp’ of the day, take a seat, and once everyone has arrived, we go over the answers and discuss. A stamp counts for 2 HW points. They have to follow the directions to earn 2 points, if they just write an answer, they only earn 1 pt. I do a quick spot check, but don’t make any corrections at this point. I randomly pick on students each day to give an answer and they make corrections as needed.

 

 

Welcome to my blog!

I hope you are enjoying your summer! August will be a busy month as teachers prepare for a new school year. If you are a new teacher, or a veteran teacher, looking for new science lessons and ideas to add to your curriculum, my website is here to help. Everything I have posted is free for you to use in your classroom. All of my Google Slides can be edited to meet your needs – here is a quick tutorial to help you make modifications.

To help you find what you need quickly, there are several options available:

Search box in the upper right corner – click on the magnifying glass and enter key words to find lessons.

Tag cloud – scroll down, on the right you can choose either a topic or standard. Each blog entry also has tags on them to help you find related lessons.

Category Menu – scroll down on the right and look for lessons related to your topic, such as ‘Life Science’ or ‘Skills’

Enjoy the rest of your summer and best wishes for the 2018-19 school year!

 

FREE Periodic Table Battleship Handout

We are having a tech-free day and thought between Transition Metal Bingo and Periodic Table Battleship, my students will really get to know how to find elements on the Periodic Table. We are just learning about how the Periodic Table is arranged according to Families, how to determine Shells and Valence Electrons, and how to draw Bohr Diagrams and Lewis Structures. Click on the links to for detailed lesson information.

I wanted a simple handout for my students to use and that was easy to manage. Most of the Periodic Table Battleship games involve expo markers and file folders, but that is time consuming to set up and clean up. Using this handout, they can use two different colored highlighters, crayons, colored pencils, etc. to keep track of their boat placement, hits, and misses. I have ‘privacy screens’ that we use during tests and quizzes that they can use to keep their papers hidden from their opponent.

Metric Ruler – Guided Practice for cm & mm

Ruler Practice (Student Copy)

Materials:

20170927_132725

I use this activity as a guided review of reading metric measurements in cm and mm. Each student receives one metric measurement, you can laminate and hand out individual task cards to students, or simply print and cut apart so that students can write on each card as well.

As the measurement is projected on the board, the student with that task card will come up to the board and draw a line on the ruler for to represent that measurement, and add the value. Each student will mark the measurement on their own handout as well. Advance to the next slide, and a new student will add their value to the ruler. Continue until all students have added their values to the ruler,

Qualitative vs. Quantitative Observations Worksheet

Quantitative vs Qualitative Observations

Click link for the PDF of this worksheet: Qualitative-vs-Quantititive-Observations

This is a nice review sheet to practice identifying Qualitative and Quantitive observations. Qualitative (think quality) are observations you can’t really put a number on, while Quantitative (think quantity) are observations that are measurable or have a number value. In this exercise, I have the students also underline the word(s) that help them decide if the observation is Qualitative or Quantitative.

For fun, and to review Inferences, I have the students infer what the dog is thinking as s/he listens to the human given directions 🙂

Making Predictions

Here is a simple experiment to incorporate making predictions and reading graduated cylinders. I have two 1-Liter graduated cylinders set up, one in a glass cylinder with blue food coloring and one in a plastic graduated cylinder with green food coloring.

I filled both with water a few days before the start of school and an equal amount of drops of food coloring. Students will make predictions on small post-it notes and place it on the drawing of a large graduated cylinder. Where do they think the water level will be at the end of school? Will it evaporate before school ends? By what date?

I will also have them come up with factors that affect the rate of evaporation on larger post-it notes. What affects evaporation? Will the air in our classroom be drier in the Winter when the heat is on? Is our classroom humid now since it is warm out?

I will post their predictions and questions next week. At the start of the month, I will also post the volume so they can see the evaporation rates over time.

Famous Scientists “Wanted Poster” Using Google Draw

Wanted Poster Sample- Jacques Cousteau.jpg
Sample Wanted Poster

Added 8/8/18:

Lesson Information

This is one of my favorite projects of the year and using Google Draw allowed the students to work on it both in class and at home. In the past, we used a software program to design the posters, but it had a lot of restrictions as to when and where they could work on their posters. By using Google Draw, students were also able to share their posters with me and I could proofread it much more easily and offer suggestions.

We hold a scientist ‘draft pick’ when making our selections. Students come up with a list of their ‘top 10’ scientists and each student draws a number. I select a number randomly and whoever has that number gets to choose first. Once a scientist has been chosen, no one else is allowed to pick that person. Sometimes students choose to spin the “Wheel of Science” when they are not sure who to pick and will allow the wheel to pick for them.

Basic Requirements:

  1. Google Draw to design your poster – Print in color on 8 ½ x 11 paper
  2. First, middle, and last name of your scientist
  3. Picture of your scientist
  4. His/her birthday (Month, Day, Year if available)
  5. ONE sentence of why they are famous or “wanted”  
    • This sentence has to be approved
  6. Country he/she was born in
  7. Where he/she did their work – was it at their home, at a school, a lab, etc
  8. Date of death or current age if living today
  9. Summarize His/Her accomplishments in your own words:
    • One paragraph using 3 – 5 complete sentences
  10. Your name in the bottom RIGHT corner of your poster
  11. List of your sources used for information, pictures, etc on a separate Google Doc.

Choose up to 4 of the following requirements to add to your poster:

  1. A quote by your scientist
  2. 1 – 2 additional pictures of your scientist
  3. A picture of what they worked on
  4. Where they went to school/college
  5. If they had any other jobs
  6. Family information: husband/wife, children, parents, brothers, sisters
  7. What else was happening in history when this scientist was famous
  8. Did this scientist work with another scientist?
    • Who was it and what did they do?
  9. Are there any museums or other places that are named after your scientist? Where is it?
