Life Science Plant Specimen Dissection or Separation of Parts by a 6th grader

Welcome to Science Grades 6 to 8 from USA Heartland! I'm Becca S, the blog owner. This post is to share some photos of a 6th grader's efforts at home with a variation to my suggestion for gathering some plant specimens for a small collection. When the remote learning switched from plants to invertebrates with earthworms as a topic, I made a Google Classroom comment about earthworms being one of the very first things I learned to dissect in Biology I. This female 6th grader started exchanging comments with me fascinated on how to open a worm.

At home this student isn't quite dissecting but she is gently pulling apart and separating then identifying parts with labeling. She's doing all this on her own as an extension activity (extra; not required). I'm impressed. She's formatted everything neatly which was something learned in science class before Act of God Days and Remote Learning. Permission has been received to share her photos from 2 recent days:

*use of technology by sharing digitally the photograph with teacher

I'm making this blog post short and sweet to let the amazing work of a 11-12 year old speak for itself.

Thanks, mystery student!

Life Science Plant Specimen Photography by a 6th grader

Welcome to Science Grade 6 to 8 from USA Heartland! I'm Becca S! I live, teach, and do science in the Midwest. Crazy temperatures last week in the midst of a crazy world fighting to stay alive. The focus of this post is not the pandemic but some amazing closeup photographs snapped by one of my 6th graders. Student "C" has taken on the challenge of doing the extensions I've suggested, which means this is extra. It's not required as part of the pass/fail system that our district has during Remote Learning Days.

My extension suggestions for each JH grade have been a scientific lab-related skill that they can safely do at home with minimal fuss and supplies.

The 6th graders have just switched from plants to animals (invertebrates) in the past 3 school days, so collecting or photographing plant specimens got continued for a few more days.

Student "C" provided facts about each plant along with a full specimen photo and a closeup pic. The quality of the snapshots have been fantastic! I've really enjoyed receiving this student's yard tour!

Remember this is a sixth grader. 3rd quarter we've tried to work on lab drawing and realism art skills like accurate details, sizing, and scale. This student has remembered to tell me the plant name, where it is commonly found, and several characteristics of it. By taking the photograph, "C" is documenting and by relaying it to me, "C"'s sharing his work. And now with his and his parents' permissions, internet technology is giving us the opportunity to share with a larger audience. (THANK YOU.)

Enjoy Earth's variety on this Earth Day evening:

And the final one I've saved is a 'lone wolf'=

There have been a few others I've seen but I failed to save. However with these that are featured in this blog post, please take time to click on the closeup photos to zoom out in order to be amazed at the intricate details that can be observed.

Thanks for taking time to read and view how a few of us are DOING science in the USA heartland!

Physical Science Pre Chemistry Mixtures or Solutions Demonstration shared by student

Welcome to Science Grades 6 to 8 from USA Heartland blog! I'm Becca S and I have several blogs about different educational interests, genealogy research, and paper-crafting projects. This particular one focuses on sharing hands-on experiences with current junior high science students--even remotely delivered. Yes.

Before Act of God days and now in Remote Learning days designated during stay at home orders, eighth graders had started some pre-chemistry topics about mixtures and solutions. I thought proceeding might be too difficult for students to do on their own so I switched to sound and light waves and electricity basics worksheets during our first 3 weeks. Now that the students have received their textbooks during a school district designated curbside delivered pick-up, I've backtracked to assign textbook reading and questions in order to further their understanding.

However I thought a great extension or extra they could do would be to send me photos showing examples of household tasks that they believe demonstrates a mixture or a solution. So far I have 3 students of 16 who have attempted this and 1 has sent me some phenomenal sequenced pics that I asked her for permission to share with my blog readers.


This is from "A"=

Yesterday she demonstrated chocolate milk made with Ovaltine and skim milk. The photos were sequenced just like the montage seen above.

I just thought this was a phenomenal way to have students still DOING science.

She's documenting, sharing results, using technology for the documenting and sharing, demonstrating sequential formatting, etc.

LOVE this!

Life Science Grade 6 Plant Specimen Drawings

Building skills of lab drawings, charts, illustrations, and/or timelines

During the last 7 weeks of third quarter in winter-early spring of 2020, junior high students have had skills challenges on Tuesdays and Thursdays for the first 10-20 minutes of class related to weekly content.

Just before the stay-at-home orders for Covid-19 virus, the sixth graders had skills challenges to recreate illustrations of root tip, internal view of phloem and xylem for a plant stem, and 2 others before being given the challenge of a 20 minute specimen drawing to fill a full page! 

Three different plants were placed at different lab tables with 6 students at each plant. Students were divided on each side of the plants and were told to strive for realism from the perspective of their location. 

At this junior high, having a weekly art class stopped at the end of 5th grade. So even though this was assigned to develop their lab drawing skills before they reach 9th grade biology or honors biology, it benefitted the students with creative learning styles tremendously. [and I realize some of you would be baffled about the time span between 3rd quarter sixth grade and 1st quarter ninth grade, but now after 2 weeks of being homebound, I'm so VERY thankful for the time we did have and the progress that I was already seeing, especially with this age group.]

At this age and stage, I still have 3 boys and 1 girl who are very heavy handed with their lead pencils! Their skills progression to be precise, accurate, and finely detailed has been painstakingly slow. 

I don't have photos of the finished drawings, yet, but these are from their drawing time as I was walking around and monitoring their work:

Each plant has the same container with a bit of dried floral moss but the type of plant and size vary greatly.

6th graders!!! Involved!

100% student engagement! The students didn't want to stop which says a lot for the progress they've been making from the first skill challenge back in late January! I would have heard moaning and groaning complaints like I can't draw that!, I can't draw for 20 minutes!, Do I have to?, etc. (tee-hee; oh, my brilliant plans are coming together perfectly, my little chickadees!!!!)

Life Science Grade 6 simulation for slime molds

Using oobleck to simulate texture of slime molds

About 2 months ago in 6th grade science the module textbook about Microorganisms-Fungi-Plants, identifying slime molds was part of a section included with bacteria, molds, and viruses. I thought using oobleck has a simulation activity for the texture would be helpful for this age of student.

At the time student desks were arranged in pods. This class has 18 students so the room has 3 sets of 4 desks and then 2 sets of three. Each pod received a bowl with cornstarch, a beaker with water, and a plastic spoon for each container (with strict orders not to mix the spoons up and 'contaminate' their supplies). Each student received paper towels to protect their desk, a clear cup, a spoon for mixing and stirring.

Food coloring was distributed about midway to make sure the students got their basic oobleck made.

Some students because of their hand size being too big, ended up cutting off the top half of their cups in order to use their fingers to get ahold of the mix better. 100% engagement with this activity. On my end, I was leading a discussion and asking questions about how this reminded them of photos seen in textbook and online about slime molds. 

Students' comments were interesting and they understood the analogy. 

Here are two pics taken during the activity:

I found a form online that goes through the steps and cautions students to use a little bit of water when adding to the cornstarch. That was read before supplies were distributed. 

Overall, this was a great opportunity for the students to have a hands-on and safe activity for their chapter and it also led to discussion about how this would work for other science topics (physical and chemical changes).

Crater Impact Study Started with 7th graders

Yesterday, September 20, 2019 seventh graders and I started experimenting with flour and colored water to serve as a crust layer along with gathered parking lot rocks as meteoroids to try different angles and heights (10", 20", 30", and over 36") for solar system impact observation study.

Here are a few photos in action yesterday:

I took photos of all 4 groups but I don't know what happened to the rest of the photos. I'll have to follow up later. Each group had different colored water (blue, purple-blue, green, and red). Equipped with yardsticks to check the different height drops, students were trying to coordinate different tasks including data keeping. However, data keeping went by the wayside as playing with the flour and water after 'meteoroid' landings needed to be checked for depths of the impact craters. [math integration] 

Supplies were: old metal baking pans, paper towel layer, flour (about 2 lbs.), squirt bottles, food coloring, water, rocks of different sizes, yardsticks, yellow copy paper for data, and pencils.

Oh, what a mess they made however they were so excited to be 'doing science' that I couldn't get too upset and frustrated with them. Afterwards as they finished cleaning their hands and were getting their stuff to go to their next class, almost every one of the 13 (of 14) seventh graders made a comment about how cool that was....

Mini Catapults Building and Launch Trials for Projectile Motion Learning

During the previous 10-14 days, the 8th graders had most of 3 class periods and some study hall time (option for students) to work on the construction and launching of their pom-pom. The target distance was 12" from their base.

At first I only wanted their hand/finger to be on the launching part but after much frustration on their part, I decided to have them include that as an influencing factor in their data results. Students were glad about that.

With overhead ceiling fans, some portable fans, and open windows, students had other factors that could impact their projectile motion distances.

Here are some photos taken on Day1=

Before the first class period working on this, I prepared small supply kits for each of my 16 eighth graders. Their kits included 6 small craft sticks, 3 jumbo craft sticks, 1 plastic spoon, 1 binder clip (these varied in widths due to buying an assortment package from Dollar Tree), 3 small and 1 large rubber bands, 1 pom-pom, and 4 glue dots. Protractors were borrowed from the math teacher so students could be more accurate in determining angles for launch trials.

Yardsticks and rulers were available to help determine distances. Lots of math integration within this activity with students creating their data tables full of details on their trial launches of 3 angles with 3 trials at each angle to look for consistent results and then 1 angle picked with 3 trials with catapult on top of 1 textbook and then either the same angle or a different angle picked with 3 trials with the catapult on top of 2 textbooks. Students were to notice if the height adjustments increased the distance in their projecting.

A couple of students got super frustrated on Day 1 and one male was a bit overzealous but overall students really enjoyed this and loved having this opportunity to experiment. Their dedication and focus to this activity were joys to observe. And the amazing ripple effect is having 6th & 7th graders wanting to be able to do this!!! I was flooded with questions from guys and gals about when they could make a catapult!!!!

Loving this teaching gig! Next post is about crater impact with 7th graders...

Greeting to this new blog

Welcome everyone!

We are excited to be sharing the blogging world via internet technology from our little community school. Tonica is a small north central Illinois community. It is only a few miles from the spectacular Starved Rock State Park, Illinois and Vermilion Rivers.

We are also small in numbers but big in enthusiasm for learning more about science. Check back often as we start to share a little of what is happening in the middle school science room as of September 2019.
