2018 Science NTI  

Scott County Freshman

All students were given a paper packet to take home before Christmas Break. They should complete the following assignment from the packet for each day out for NTI- to be turned in the next school day.  I will be available for help on NTI days from 9-12 and 1-4.

You may contact me by:

Student Assignments:

Click on the Brewer NTI Plans link below for a copy of all review pages.   They are also located on my Google classroom page (each student has access to that).

These assignments are a review of things we have learned this year so far.  We practice these things as flashbacks daily and are the "big picture" topics of each unit.  On the next school day after an NTI day(s), we will have a short assessment over the information on the reviews.  This will be entered as a grade!

      Read the following experimental scenario and identify the variables below.

      Mary investigated the effect of different ages of compost on the growth of tomato plants.  Mary hypothesized that plants grown in a soil mixture with 50% aged compost would show better growth.  She grew 4 flats of tomato plants, each with 10 plants per flat as follows:  

      • Flat A:  100% potting soil

      • Flat B:  50% mixture of 2 month old compost and potting soil

      • Flat C:  50 % mixture of 4 month old compost and potting soil

      • Flat D:  50 % mixture of 6 month old compost and potting soil

      The plants received the same amount of sunlight and water each day.  At the end of 30 days, Mary recorded the height of the plants (in cm), the general health of the plants (healthy or unhealthy), and the quality of the leaves using a four point scale as follows:  4= green, firm, no curled edges; 3= yellow-green, firm, no curled edges; 2= yellow, limp, curled edges; 1= Brown, limp, curled leaf.

      1. What is the independent variable? __________________________________________________

      2. What is the dependent variable? _____________________________________________________

      3. What are 2 constants in the experiment? _________________________________________________________

      4. What was the control group? _______________________________________________________

      5. When graphing this data, what would go on the X-axis? ____________________________________________

      6. Why?  ____________________________________________________________________________________

      7. What type of data is best represented by a

        1. Pie graph _________________________________________________________________________
