Learning Target

Use strategies to develop formulas for finding the circumference of circles.

 Exsample:

32.1÷12.3=?

32.1÷12.3= 2.610

 Lession:

If you multiply the ratio by the diamitor you get the cercoferance. That is called PIE. 

Learning Target

Estamateing sums and differentses using desimals.

Esample:

54.12+21.45 = 75.57

54.00 = 21.00 = 76

89.34 - 45.17 = 44.17

89.00 - 45.00 = 44

Lession:

When you find the estamated anwer, you must...

Round, then add or subtract. the answer must be a whole number.

If the number has to be rounded up, know that your sum or difference

will be a bit higher than the real answer.

Questions

• Which solar water heater backround works best, black or white?

• Will the tempture increes more if we cover the heater with a lid?

Prediction/Hypothesis

IF: There is uncovered black plastic solar water heater,

THEN: the water will increase the temperature more. Coverd black attracts the most heat.

Results in sentance form

• Coverd black attracts the most heat. It increases the most in tempurature
  

Conclusion statement based on data and results

• A black solar water heater that is covered will increase the tempuature best.

 

Chages for next time

• We could use a different desine for the solar water heaters.
