Balancing Chemical Equations Activity – one of my long time favorite activities. Students will learn how to read formulas, count atoms, create and read chemical equations, and balance chemical equations using a hands on activity with color coded formulas cards.
Lesson Resources: Create one set of materials for each pair of students. Store in a large zip-top bag
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.
Google Draw to design your poster – Print in color on 8 ½ x 11 paper
First, middle, and last name of your scientist
Picture of your scientist
His/her birthday (Month, Day, Year if available)
ONE sentence of why they are famous or “wanted”
This sentence has to be approved
Country he/she was born in
Where he/she did their work – was it at their home, at a school, a lab, etc
Date of death or current age if living today
Summarize His/Her accomplishments in your own words:
One paragraph using 3 – 5 complete sentences
Your name in the bottom RIGHT corner of your poster
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:
A quote by your scientist
1 – 2 additional pictures of your scientist
A picture of what they worked on
Where they went to school/college
If they had any other jobs
Family information: husband/wife, children, parents, brothers, sisters
What else was happening in history when this scientist was famous
Did this scientist work with another scientist?
Who was it and what did they do?
Are there any museums or other places that are named after your scientist? Where is it?
New for 2016 – to see the older version with additional lesson details, please visit my post from last year.
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…
Words to cut apart (pdf) – this year I removed the word “bone” to change it up a little
white paper cut into 1/4ths or small index cards
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)
I updated my Dunkin’ for DensityLesson for 2016, I use this lesson with my 6th graders as part of our unit on properties of matter. I wanted it to be more data driven and have them analyze the data from all of their trials, and then compare their data to their classmates. I changed the objective to:
Change the density of the film canister so that 90-99% of the canister is suspending under water.
I have been getting a lot of requests for editing access to the Google Slides on my blog, so I wrote this tutorial on how to save and edit any of the Google Slides on my website. I can’t permit editing rights because it will change my copy of the slides and your edits will be visible to everyone that visits my blog.
Lesson Plan: Substituted Sammy Google Slides (Public) modified from: “Substituted Sammy”: An Exercise in Defining Life, Donald F. Shebesta, The American Biology Teacher, Vol. 34 No. 5, May, 1972; (pp. 286-287) DOI: 10.2307/4443933
I love using this activity as an introduction to get my 7th grade students thinking about the idea of living vs. nonliving. How do we define life? How do we know something isn’t alive anymore? How are living things different than nonliving things? How are nonliving things different than things that were once living? What characteristics do living things have in common?
To start the lesson, we brainstorm and try to pin point what it means to be alive. Accept all answers and write them on the board. After our brainstorming and discussion session, I draw Sammy on the board in one colored dry erase marker ( ie blue) and ask students to do the same. I explain that we are going to learn about Sammy and every time something about Sammy changes, I will draw it in a different color (ie red) and ask students to do the same in pencil.
As the story progresses, I also draw a dialysis machine, IV bag and stand, ventilator, etc… and essentially, end up drawing a robot at the end. This leads to some great discussions about what we can do now, and what we can’t do yet, in the medical field. It also brings up the discussion about the quality of Sammy’s life, at some point is he really living his life or just alive? I ask the students to give Sammy a percentage of “living” as we go through the slides, is he 50% living, 80% living, 25% living, etc and they give a wide range of answers. I then reveal it is a trick question, the answer has to be either 0% or 100%, you can’t be partially living, biologically speaking – you are either alive or not alive, there really is no quantitative scale. Quality of life is not a biological definition, instead it is an ethical issue and everyone has their own definition or belief system. (And then there is the gray area that Viruses fall into ;))
This introductory lab is a fun way to analyze data and the students look forward to finding the results each year. Who will be taller, boys or girls? Will we be taller than last year’s class? You can really analyze the data in multiple ways, you can also add the concept of min, max, mode, and range in addition the mean, you can look for trends, and you can talk about sample size, etc…
This post highlights the eight Scientific and Engineering Practices and spotlights a few lessons related to each practice. I had this as eight separate posts but decided to consolidate for easier viewing.
