G7 Week 17

Last week in science!

Monday, January 14th (Day 0)

Today in science: Today is planting day! The main themes for today’s lesson were “seeds” and “germination.” Each student was shown how to place their 4 Brassica rapa seeds into their plastic soil-filled plant containers. They were also shown how to place their 2 Brassica rapa seeds into a Petri dish filled with moistened (water-soaked) layers of paper towel. These two ‘treatments’ form the basis of an investigation in which we are trying to experimentally answer the following question:

What is the effect of the presence (and absence) of soil on the successful germination of Brassica rapa seeds?

Dr. M also announced that there will be weekly reading quizzes every Friday during the Wisconsin Fast Plant (WFP) unit. Every reading quiz is based on a one-page weekly reading given to students on Mondays. The Week 1 reading quiz will ask questions about the reading titled, “About Wisconsin Fast Plants.”

Homework: Students have been asked to make a proportional timeline to illustrate the complete life cycle of Wisconsin Fast Plants. This timeline is explained in the reading titled, “About Wisconsin Fast Plants.”

Tuesday-Wednesday, January 15-16th (Day 1-2)

Today in science: The main themes for today’s lesson were “seeds” and “germination.” Dr. Merritt collected homework at the beginning of class. While some F period students needed to put their Brassica rapa seeds into their Petri dishes, most students used the first part of the lesson to make observations of the seeds they put into their Petri dishes yesterday. All observations were recorded in a new Lab Notebook entry.

Homework: Students should continue preparing for Friday’s Reading Quiz, which students were told on Monday will be based on the 5 key ideas contained in the reading titled, “About Wisconsin Fast Plants.”

Thursday, January 17th (Day 3)

Today in science: The main themes for today’s lesson were “seeds” and “germination.” After collecting and organizing their materials needed for today’s lesson, students were given time to work on the tasks shown below.

1. Make observations of seeds with no soil (Petri dish). Enter observations not only in the already prepared data table in the lab notebook, but also make a drawing of at least one of the two seeds, whether germinated or not.

2. Make observations of seeds with soil (planting container). Enter observations not only in the already prepared data table in the lab notebook, but also, if any plants have successfully made their way out of the soil, make a drawing of one of the germinated plants.

3. Make a data table on a single, loose sheet of graphing paper (not in your lab notebook) in which to keep track of the height of the four plants planted in your plant container (or containers). To see the example table that Dr. M displayed on the whiteboard during most of today’s class, click on this link.

4. Any remaining time in the today’s lesson was to be used to prepare for tomorrow’s reading quiz (see Monday).

Homework: Students should continue preparing for Friday’s Reading Quiz, which students were told on Monday will be based on the 5 key ideas contained in the reading titled, “About Wisconsin Fast Plants.”

Friday, January 18th (Day 4)

Today in science: The main themes for today’s lesson were “seeds” and “germination.” After taking the Week 1 Reading Quiz, students were given time to work on the tasks shown below.

1. Make observations of seeds with no soil (Petri dish) and record them in the lab notebook. These observations included making drawings of any already germinated seeds.

2. Make observations of seeds with soil (planting container) and record them in the lab notebook. These observations included making drawings of any already germinated seeds.

3. Measure the height of the seeds with soil (planting container) and record them in the 6 column x 56 row data table we created in Thursday’s class.

4. Begin reading next week’s (Week 2) Weekly Reading, “Getting to Know Seeds”, and use it to get a head start on next Monday’s homework assignment, which is described on the back of the Week 2 reading.

Homework: There is no science homework this weekend.
