Personal Connections 15 January 2012

Dear Students and Parents,

In our Unit: Changing Materials, we have been inquiring in into the properties of various materials. We have been working hard to write up our experiments and form tentative conclusions.
So far we have completed experiments to test:

  • How different materials react to being hit hard?
  • Which threads have the greatest tensile strength? 
  • Which materials insulate the best?

This Week’s  Personal Connections Task

You are to conduct two experiments on a  local soil sample, as directed in your Personal Connections Book. You are welcome to borrow any equippment from school which you are unable to locate at home.

Experiment 1: Testing Soil
You will need to:

  1. Read the introduction
  2. Gather the necessary apparatus and soil sample
  3. Read the method
  4. Create a research question for your experiment
  5. Write down you predictions (How long do you think it will the water take to pass through the soil? How much water do you think will pass through?)
  6. Follow the step by step method 
  7. Record your results
  8. Form tentative conclusions (Use the what’s going on in the green box to help you)

If possible take a photograph of you with your experiment and paste it in.

Experiment 2: What’s in your soil?
You will need to:
  1. Gather the necessary apparatus and soil
  2. Read the method
  3. Create research question for your experiment
  4. Write down you predictions (Estimate what fraction of your sample will be gravel, sand, silt and clay?) 
  5. Follow the step by step method
  6. Record your results
  7. Form tentative conclusions (Use the what’s going on box to help you)
  8. Draw a scientific diagram in pencil to represent your soil after it has settled (Use the diagram provided as a guide)

Finally bring in your soil sample to school so we can compare it with the rest of the class.
