$2,000 School Garden GRANT opportunity!

Applications are due by Wednesday, Nov.15th. This should be a fun learning experience for all ages! Students get involved with good health practices, starting with natural, home (school) grown foods!  Good luck! (check out the success stories)

Students will be evaluated upon the various concepts and/or ideas that we have learned about the scientific method. On Monday, students who have continued to be on-task have had an opportunity to review the many concepts that are based upon the scientific method, while those that dilly-dallied have to work on them at home and study them.

The list includes objective, observation, hypothesis, procedure, data, quantitative analysis, qualitative analysis, conclusion, inference, model, theory, law, independent variable (experimental variable), dependent variable, controlled variable (constant variable), peer review, mass, volume, density, and triple beam balance among others.

Scientific Method Lab: M&M’s (Due Monday, Sept. 25, 2017)

Students are to use the attachment below and follow the directions for the M&M lab in the handout through the application of the scientific method, as well as answer any pertinent questions that are provided for this lab activity. Remember that this assignment will be graded as a summative evaluation. For each day this assignment is late, one letter grade will be deducted, for a maximum of three downgrades.

Paper Towel Lab Write-Up

Those students who did not finish the lab write-up portions on the data analysis and conclusion, need to make an effort to work on them between tonight and tomorrow night, since you will have a short period of time in class on Thursday to complete it and turn it in along with your group members.

Again, as a reminder, since you worked in groups, you and your group members should have the same information in terms of the objective/problem, hypothesis, materials, procedure, and data (including the graph of the data), but you WILL differ in your critical thinking skills when it comes to the actual writing of the data analysis and conclusion, but you are permitted to VERBALLY/ORALLY discuss your experimental results (data) with your group members, as each member needs to formulate his/her own thoughts on paper. Copying the analysis or conclusion of someone else will automatically result in a grade of zero!

Application of the Scientific Method

Students are expected to read their class notes about the scientific method a few times to be better prepared to tackle the task at-hand on Monday, as well as be able to apply this systematic approach later on this week, when a two-day assignment will be given as homework. This assignment will be considered as a summative evaluation grade, since it will encompass what you’ve learned and practiced in class this coming week.

For those individuals who have scheduled a density retake test on Tuesday during lunch at 10:20, do not forget to review this weekend your class notes and the problems on how to solve for density, mass, or volume. Also, you will have the option to eat as you work on your retake, since the test should not last more than 25 minutes.

Density Test: Problem-Solving (Story Problems)

Students will be evaluated on their scientific and mathematical skills based on their comprehension and application of the processes for determining their learned variables, namely, mass, volume, and density.

Students are expected to read each problem, write down what is given in each problem, and determine what is needed to find out, and then solve each problem, similar to our examples that we have done in class.

Students are highly advised to review their notebooks, since we have done several problems on the board in class.

Students are to use the following website

to simulate their work on density by determining the mass and volume of five (5) different objects, and then calculate the density of each object. Once the density is determined, each object can be easily figured out whether it floats or sinks. Do remember that this is based on the relationship of the density of an object to the density of water, which we agreed upon to be 1 g/cm³.

Note that you are to use only the water to report your data, but you can try different liquids for your comparison purposes, but those do not need to be turned in; ONLY those that are used with water need to be turned in a table format as it is a summative evaluation (5 column-headings and 5 rows with the collected data).

Calculating Density!

Students will work in pairs to determine the density of several small regular and irregular objects by measuring the mass and volume of each object.

Note that regular objects require the measurements of the length, width, and height (or thickness) of each object and multiplied by each other, in contrast to irregular objects that require the process of water displacement, whereby the initial water level is read and recorded, and the object is then gently lowered into the measuring tool such as a beaker or a graduated cylinder, and the new water level is read and recorded. Then the difference between the initial and final water reading gives us the volume of that irregular object.

To calculate the density of that object, the mass of the object is divided by its volume. The answer for the density of the object needs to be expressed in terms of g/cm3 or g/ml, since the mass of small objects is measured in grams (g), and the volume of small objects is measured in cm3  or ml.
