Comparing Surface Temperatures

Liz BelasicLeave a comment
Demo Set up – heat lamp, rocks, sand, water

Materials:

  • Heat lamp
  • Stand
  • Clamp
  • Infrared Thermometer
  • 6 beakers each of sand, water, gravel (other items can be used, or more than 3 can be added)
  • Meter Stick
  • Handout with instructions, data collection, and questions (Google Doc)
  • Google Sheet for graphing (Google Drive)
  • Newsela Reading – Heat Islands & Questions (Google Doc)

Directions:

Day 1:

Explore the campus on a sunny day and select both natural and manmade surfaces and record data. Enter data into spreadsheet – what patterns do you notice?

HW: Read newsela article and answer questions, discuss next class, how does this relate to our findings today?

Day 2:

Set up heat lamp experiment for a minimum of 25 minutes, make predictions, which surface will heat up the most? How hot will it get? What location (1-6)? Enter data and discuss results.

HW: Lab write up and discuss results next class

This was the first time I did this experiment, and seeing the results definitely had the ‘wow’ factor with my 6th graders, seeing the temps was actually surprising, esp for the rocks under the heat lamp. Many students thought the sand would be the hottest from their experience walking on hot sand at the beach in July/Aug. Also, the surface temp of the playground was surprising since it was a rubbery light colored composite and not dark colored asphalt. Prior to this activity, we took notes and discussed heat – radiation, convection, and conduction, and notes on sunlight and how it causes the seasons and different climates on Earth. Under the heat lamp, position 1 was analogous to being at the equator while position 6 was at the poles. The Google Sheets will automatically graph your results once the data is entered.

If you use this activity, would love to see your results!

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

Liz BelasicLeave a comment

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.

Public Copy of Science Prompts 2017-18.jpg

Google Slides – click 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.

Metric Ruler – Guided Practice for cm & mm

Liz BelasicLeave a comment

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 🙂

Distance Learning Edition May/June 2020

Mineral Cube 2020 – Distance Learning was not going to stop us from completing this annual tradition! Students chose their top 10 Minerals and we completed the 2020 Draft Pick using a random name picker to determine the order of each pick. We used one of our Live Zoom Sessions for me to explain the project, go over tech issues, answer questions, and to complete the draft pick.

Using Google Classroom, I made a copy of the template for each student and was able to review their work each day. Students then spent 3 days researching and designing their slides, then a few days building their cubes. We then shared our cubes using Google Slides – each student added their info to one slide and were able to see each others completed Mineral Cubes.

Sample Google Classroom directions:

For the next 3 science classes – you will work on your Mineral Cube Research and gather supplies for your Mineral Cube. I will grade 2 slides each day and give you a classwork grade. When we have LIVE classes, you will sign in and I will look at your slides in real time and answer questions and make suggestions. 

  • Lesson 17: Slides 3 & 4 – the TOP and BOTTOM of the Cube
  • Lesson 18: Slides 5 & 6 – Chemical and Physical Properties of Mineral
  • Lesson 19: Slides 7 & 8 – About and Uses of Mineral
  • Lesson 20:
    • 1. Finalize your slides – make corrections and read my comments, and complete your slide designs.
    • 2. Print and cut out the 6 sides of the cube.
    • 3. Assemble your mineral cube.
    • 4. Add pictures and videos of your mineral cube by Monday to the slides posted for 5/11.

2020 Update Google Slides Template Link – Mineral Research

Completed Slides Template  – Students had the option to upload a video of them holding their Mineral Cube and showing all the sides in addition the images of each side.

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?

D & T Activity Updated for 2016

Liz Belasic4 Comments

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)
