Diffusion Lab – Iodine & Cornstarch

This slideshow requires JavaScript.

Materials and Set Up – this was so easy and inexpensive to do and had the same effect as using dialysis tubing. Great demo/lab as part of our unit on osmosis and diffusion!

For every two students:

  • handout from Biology Corner
  • large beaker
  • inexpensive sandwich bag – non sealing (I used Wegmans 150 ct)
  • 1 tbsp corn starch
  • 50 mL water
  • rubber band
  • clothes pin
  • graduated cylinder
  • 100 mL Iodine dilution

Iodine Preparation

  • 20 ml Iodine added to 500 mL of water
  • measure out 100 mL of diluted iodine for each group

Prelab Prep:

  1. Place one bag over each beaker
  2. Add 1 tbsp of cornstarch to each bag
  3. Add 50 mL of water to each bag
  4. Check for leaks
  5. Use a rubber band on each one to keep closed
  6. Clip bag to beaker

Observations

  1. Students will add iodine and make observations – changes will take place within a few minutes and the longer it sits, the darker it will become.
    1. Iodine is able to pass through the plastic bag, the starch is not
  2. Have students lift the bag out to see the changes that are taking place
  3. Discuss

Update – I let the set up sit over the weekend, and when I came in today, the water was almost completely clear – looks like just about all of the iodine moved into the bag:

Star Wars Characters for seating

I love Star Wars and found these really cute characters to use for my seating assignments. I have black lab tables and tape on one of the characters such as “Chewy” or “R2” in the corner. I also use the characters to assign partners and seats randomly.

PS – not 100% sure who the redhead is, assuming little Anakin? General Hux had red hair. Also, Han used a light saber, once, on the Planet of Hoth to cut open the tauntaun to save Luke – kids often ask about it.

Free Science Starters, Bell Ringers, Warm Ups, Writing Prompts

Public Copy of Science Prompts 2017-18.jpg

Google Slidesclick here to access my Science Prompts from 2017-18. The slide # is the prompt #. For example, slide 14 is prompt # 14. These are the ones that I wrote – I deleted copyrighted material from other sources such as science starters from Science Spot. 

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.

Meiosis & DNA Cheat Sheets – Free

I made these cheat sheets for my 7s to help them with our Meiosis and DNA unit. These are two of the most complex topics we cover in Life Science and it helps them synthesize all of the information into one page.
