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!

Volume of a Penny Lab – New!

Problem: How can we use water displacement to calculate the volume of one penny?

Materials:

  • Volume of a Penny Lab (PDF)
  • Graduated cylinders (25 mL, 50 mL, or 100 mL)
  • Cup or beaker of water, food coloring optional
  • Pennies – 100+ per group
  • Tub
  • Plastic Spoon – to pour water out of graduated cylinder and separate pennies

Screen Shot 2019-10-18 at 10.33.54 PM

This is a simple & fun lab to have students practice measuring and reading volume as well as use water displacement to determine the volume of  a penny – an irregularly shaped object.

Students will design their own series of 10 tests with the following criteria:

  • All pennies must be under water inside of the graduated cylinder.
  • The volume of water must not pass the 100 mL (or highest) increment.
  • All data is recorded carefully.

Students were able to carefully measure and determine that the volume of a penny was 0.35 mL – most students were very close with a range of 0.33 – 0.37 mL.

Screen Shot 2019-04-05 at 8.57.22 AM.png

Quick & easy – no fuss – no mess – way to prepare cabbage juice:

  1. Chop up half of a purple cabbage
  2. Add to a coffee pot
  3. Fill with very hot water from sink or water cooler
  4. Let it sit for at least 20 minutes
  5. Pour into flasks, beakers, or plastic cups
  6. Add a pipette or spoon to containers

You can add more hot water during the day as you use it, refrigerate leftovers if using next day.

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.

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

 

FREE Periodic Table Battleship Handout

Liz Belasic11 Comments

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,
