in class

Monday, students watched two StudyJams: Elements vs Compounds and another one on Mixtures. Both are linked on my GC. Afterwards, students cut out their pie graphs of the % of elements that make up the 4 parts of Earth and glued them into their notebooks. See the picture below.

 

To help students remember the elements that make up most of Earth, I came up with titles for each part:

  • atmosphere- NO air pollution, Nitrogen and Oxygen which make up 99% of our air
  • biosphere- SPONCH CaFe, cafes serve food that was once living. Therefore, these chemical symbols are what make up all living matter. 
  • hydrosphere- H2O, formula for water
  • lithosphere- Litho means solid rock or Earth’s crust. To eat the best crust on the planet, go to SiAlO CaFe which are the chemical symbols that make up Earth’s crust.

Tuesday & Wednesday, students continued to build their knowledge of elements and compounds through the warm up and today’s activity, Nuts and Bolts. In this activity, students looked at 9 different baggies that contained nuts, bolts and or washers. They were to draw the contents of the baggies and then identify it as a representation of either an element, compound, mixture of elements, mixture of compounds or a mixture of elements & compounds. Afterwards, they were to write in their notebooks a response to this prompt: how is this activity representing or modeling elements, compounds and mixtures?

Thursday, students shared their answers to yesterday’s activity, Nuts and Bolts. Then students were assessed on their understanding of Nuts and Bolts using Plickers. They were shown 10 slides/Plickers on the board and they were to choose an answer without the help of teammates. Their assessment will be a daily grade. Before they left, they were given an assignment, Elements, Compounds & Mixtures 1 which is due tomorrow for a daily grade. It’ll prepare them for tomorrow’s quiz.

Friday, students used Eduphoria to upload their answers from their homework. Afterwards, they took their formative over elements, compounds and mixtures. If they finished early, then they were to read a short paper on metals, non-metals and metalloids. From this article, students are to color a periodic table of elements as directed in the article and write in their notebooks the physical properties of metals, non-metals and metalloids as they learned from the article. We’ll finish it in class on Wednesday, 16th.
