Element Advertisement Project Using Google Draw

Element Advertisting Template

  • This lesson is modified from the original lesson posted at ScienceSpot.net
    • Detailed lesson information, along with a rubric, can be found on her website
  • Top 10 Elements Draft Pick ElementDraftPick
    • Student will research the ‘stats’ for their favorite elements
    • Students will draw numbers to determine the order in which they will pick their element
    • Once an element has been chosen, no one else in the class can choose that element and they will cross it off their list
  • Google Draw Template: Google Draw Public Link
    • Students will spend one class period researching their element and creating an advertisement using Google Draw.
    • If not done during class time, it will be completed for homework over a few days.
    • Display the element advertisements so students can see their work 🙂

Results 2016-17

Materials per group of 3-4 students:

  • Student Handout RainbowTestTubesPublic (pdf)
  • Spreadsheet to collect data (excel – public)
  • 9-10 test tubes with test tube rack
  • Erlenmeyer flasks filled with red, yellow, and blue solutions of food coloring and water
    • 5 drops of food coloring per 200 mL (25 per 1L)
  • 3 x 25 mL Graduated Cylinders
  • 3 x 10 mL Graduated Cylinders
  • pipette
  • beaker filled with clean water
  • large beaker for used water
  • this activity took 2x 50 minute class periods

This lab is an updated version of the classic Rainbow Lab (link) that has been around since the 80’s (Measuring Liquid Volume with a Graduated Cylinder 1988). I used this for many years with my 5th graders, and previously with my 6th graders in the early 2000’s. Now that I am teaching 6th grade again, I wanted to make it more open ended and challenging. The purpose of the original version of the lab was twofold: First – could they follow directions carefully to make a rainbow? Second – how precisely can they measure liquid volume?

For the new version of this lab, I created new objectives and assessed the students based on their problem solving, collaboration, and measuring skills.

Objectives:

  • Students will be able to precisely measure liquids with a graduated cylinder
  • Students will be able to create their own lab procedures using the given parameters to guide them
  • Students will create new mixtures and solutions
  • Students will be able to record accurate data
  • Students will collaborate and problem solve to achieve a common goal
  • Students will test, evaluate, and select the best proportions to create the colors orange, green, and purple
    • each group made 3-4 different combinations for each color and had to, as a group, determine which combinations of primary colors created the best secondary colors
  • Students will follow proper lab procedures to avoid color contamination
  • Students will record and analyze data from the whole grade and compare their findings to the averages from each group, what patterns or trends did they notice in the data?
  • Students will create their own ‘designer’ color and share it with the class
    • this was fun way to wrap up the activity, we had a ‘fashion’ show with each group coming up to the front of the room to showcase their newly created and named colors
    • if time allowed, at the end we made a rainbow with each student holding their test tube and standing next to a person who had a color similar to their own, from Red to Purple

Visual assessment – all test tubes are even and you can quickly see that each color has a volume of 25mL.

Finding the Volume of Irregularly Shaped Objects Using Water Displacement

Pouring water into the graduated cylinder - approximately 50 mL.

(For lessons and resources on reading and using graduated cylinders, please see my related blog entry)

Materials:

  • 2 graduated cylinders per group of 4 students
  • 1 container of water per group
  • 1 plastic tray per group
  • 1 plastic spoon per group
    • this is used to stop item from falling into the container and to fish out items if needed
  • paper towels or cloth towels
  • green or blue food coloring – a few drops per 500 mL
    • adding food coloring helps the students to make accurate readings since it easier to see the water, plus it is fun to work with 🙂
    • I don’t like to use red or yellow, they tend to stain more than the blue and green food coloring
  • an assortment of small objects such as pennies, rubber stoppers, marbles, pebbles, etc…

Slowly adding objects into the graduated cylinder. Items like rocks, marbles, metal cubes/cylinders will crack the graduated cylinder if dropped in.

After recording our measurements, we empty the water and contents. The plastic spoon helps to prevent items from falling into the beaker, and fish items out if they fall in.
