LT: collect data to confirm that the density of water is 1 gram/ mL regardless the amount of water. Do Now: 12-1-16 Agenda: density of water What determines whether something sinks or floats in water? Does the density of water change at different amounts? https://phet.colorado.edu/sims/ density-and- buoyancy/buoyancy_en.html Class graph Flink challenge

Reflection RERUN: Recall: summarize what you did Explain: explain purpose of lesson Result: Describe results Uncertainties: what you are unsure about New: two new things you learned Write a prediction Identify variables Collect data Graph on white board Write a conclusion Float/Sink=FLINK challenge

LT: measure and calculate density of a solid as a ratio of mass to volume. Do Now: 11-30-16 Agenda: density Mr. Baur found that when he put the Coca Cola can into 1500 mL of water, the water level rose to 1900 mL. What is the volume of the Coca Cola can? When he added the diet Coke can to the graduated cylinder, it floated in the water. Why do you think the diet Coke floats, but the regular Coca Cola sinks in water? Draw a picture of what density looks like at level of molecules Steps to find density of an object 2 methods Density=mass/volume

LT: describe how two or more elements chemically combine to form a compound, their basic properties change. Do Now: 11-29-16 Agenda: chemical change Is water an element? Why or why not? How many atoms are in a water molecule? Sketch of element, compound, molecule, mixture Draw two types of chemical bonds: http://www.middleschoolchemistr y.com/multimedia/chapter4/lesson 4 Take notes on how properties change when elements combine: periodic table of elements videos

Use colored pencils to draw an atom, molecule, compound, and mixture. Use about half the page.

Molecule: atoms connected by chemical bonds Example: H2 hydrogen gas Reflection RERUN: Recall: summarize what you did Explain: explain purpose of lesson Result: Describe results Uncertainties: what you are unsure about New: two new things you learned Read compound basics handout Define and give an example Molecule: atoms connected by chemical bonds Example: H2 hydrogen gas Compound: molecules that have more than one element. Ex. H2O Covalent bond: chemical bond that shares electrons Ionic bond: electron is donated to another element to form a bond. Physical change: chemical bonds not broken, just heated or cooled or broken into smaller pieces. Chemical change: chemical bonds broken or new ones formed
