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:

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.

Download these free PDFs below:

DNA Cheat Sheet – 2017 – Google Docs – this covers the fundamentals of DNA at a 7th grade level

Meiosis Summary Cheat Sheet – 2017 – this covers the basics of Meiosis along with a comparison to Mitosis at each stage for a 7th grade level

 

 

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 🙂

Famous Scientists “Wanted Poster” Using Google Draw

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?

D & T Activity Updated for 2016

New for 2016 – to see the older version with additional lesson details, please visit my post from last year.

This slideshow requires JavaScript.

Before starting the activity, I set the stage that they are a group of archeologists and have discovered an ancient tablet at an archeological dig site. Unfortunately, the tablet is broken and as they excavate, they only find a few pieces at a time. What does the ancient table say? Scientists all over the world try to decipher the ancient text…

Materials:

  • Original Worksheet: (pdf)
  • Worksheet to compare posters (Google Doc)
  • Words to cut apart (pdf) – this year I removed the word “bone” to change it up a little
  • construction paper
  • white paper cut into 1/4ths or small index cards
  • glue sticks
  • colored pencils

This year, I wanted to try something different for this lesson. Instead of seeing how close each group came to the original phrase that was on the “tablet”, I wanted each group to analyze the findings from the other groups to compare their findings and look for similarities and differences. This would be similar to a gallery walk (see video below) but without students explaining their posters, they would view posters at their own pace and choose any 3 posters to compare for each category.

 

Note – this lesson plan is a modification of the original lesson plan from The University of California Museum of Paleontology (link)
