Quantities in Chemistry

When chemists make things, stoichiometry tells us how much they need to put in and how much they potentially can get out.

Here are some resources for studying this topic.

Some possible questions…

Here is a link to some possible questions.  The answers are at the bottom of the document.

 

 

Unit Resources – Plants, cells and photosynthesis

Unit cover sheet

Brainpop overview to cells

The Cell Theory:

  • All living organisms are made up of cells.
  • Cells are the basic unit of structure and function in living organisms.
  • All cells come from pre-existing cells.

The Wacky history of cell theory; Watch the video and answer the follow up questions.

G10 Ecosystems Resources

We will be posting various items here relevant to the ecosystems unit.

Ecosytems Basics:

Video that includes habitat and niche.   And  of course, Brain Pop!

Scientific models:

View this video to help you develop a definition of scientific models.
Another great source on the use of models in science.

Pyramids of numbers, biomass and energy

Follow the link and scroll to ‘part 3’ for activities and information on this topic.

Feedback loops:

Watch this Ted-Ed video about positive and negative feedback in ecosystems.  When you finish answer the follow up questions. You should be able to explain how positive feedback help form soil in ecosystems.

The Carbon Cycle:

Short video about the carbon cycle and global warming.

The Nitrogen Cycle and the Haber-Bosch Process:

Rotios task and TSC: evaluate the use of chemical fertilizers.

The nitrogen cycle handout.

The nitrogen cycle in flash!

Crash course video on the nitrogen cycle (first 5 mins) and the phosphorus cycle.  We won’t be looking at the phosphorus cycle this unit but it is another nutrient that is important to life.

Video about the Haber-Bosch process.

A website with a good brief overview of the history and negative consequences of the Haber process.  Be mindful of each source’s point of view.  Who published this and what are they selling?

This short video was obviously produced by fertilizer manufacturers and explains the advantages of using artificial fertilizers (when used properly).

A good comparison of artificial vs. organic fertilizers on this website.

Documentary Film:  Big River. Perf. Curt Ellis and Ian Cheney. Mosaic Films, 2010. DVD.

Test Review:

You should start this process with a review of the main ideas, topic questions and vocabulary given on the unit cover sheet at the top of this post. You can use this quizlet set to help review vocabulary.

Answers to handouts:  Food chain booklet,   Carbon cycle bookletNitrogen cycle handout.

Practice Test (suggested solutions)

The test will also contain a problem that involves making a scientifically supported judgement. You will have done one of the following practice activities to help with this:
Introducing foreign species (Sample answers)
Feedback (Suggested response)

You can try out some of the ideas about ecosystems with this simulation model. The goal is to keep as many species as possible alive for the entire simulation
