Organ System Presentations

Students have been working very diligently this past week to prepare their organ system projects. Each group will present their PowerPoint, Lab, and Visual on the following days. Because the 7th grade is hosting a Book Chat tomorrow, there may be a shortened schedule that could affect how many groups can present on Wednesday.

Wednesday
Skeletal
Muscular
Integumentary

Thursday
Digestive
Circulatory
Respiratory

Friday
Excretory
Immune
Nervous

Monday

Organ System Web Sites

To help you with your research, I have bookmarked several student-friendly websites that might help you. I will continue to update and add links to this site so check back frequently. If you find a website that was particularly helpful to your group, email me the link and I will post it. Go to the website below and click on your organ system folder to access the links.

Organ System Notes

Click on the links below to download your organ system's note sheet. At minimum, your group should address all the terms and questions listed for your organ system. Each member of the group is responsible for having their own notes in the group folder.

Designing a Lab

Below are two templates groups may use to assist them in planning and conducting their labs. One template is in an outline format and one is in the form of a concept map.

Organ System Project

This week, students broke themselves into groups and were assigned an organ system in the human body. Students will be working with laptops to create a digital presentation, design a lab experiment to conduct with their classmates, and construct a visual model or demonstration. Students will begin presenting their organ systems in class beginning the week of December 11th. Download the instructions and rubric by clicking below.

This podcast is a little bit longer than most of our podcasts, but well worth the review.

So what's up with the panty hose?

Many parents have been wondering, "Why does my child need panty hose for science class?" To kick off our unit on photosynthesis, students used panty hose, saw dust, and grass seeds to create their very own Chia Pets. We will keep the pets at school for the next few weeks and observe how they change and grow. Stay tuned!

Cha-Cha-Cha Chia

Students will be making their very own Chia Pets in class on Friday as we begin our studies on photosynthesis. Students need to bring in pantyhose and any decorative items that can be glued down, such as pom-poms, googley eyes, pipe cleaners, buttons, beads, or anything that sparkles and shines. The pantyhose may be used or new and knee-highs will work as well.

Lab Report

Students will be analyzing their data and writing lab reports based on their Eggcellent Eggsperiment. The lab reports should be typed; however, if this is not an option, the students may hand write their report, using pen and only writing on the front sides of the paper. Graphs should also be made on the computer, but again, if this is not an option the students may neatly make them by hand but should use computer paper or graph paper, not notebook paper! Students will have one day in class to work on rough drafts, ask questions, and proof read. Below is a rough draft of the lab report expectations, but more specific details will be presented in class. Lab reports are due on Friday, September 22.

Sunny Side Up

This week students are participating in an Eggcellent Eggsperiment. For the past week we have been studying about cell organelles. Using a chicken egg, students will model how the cell membrane works to allow certain materials to diffuse into or out of the cell. We left the eggs soaking in vinegar over the weekend so that the shell would be dissolved, exposing the membrane. Students will be using various solutions, including salt water, dye, and syrup, to soak the eggs overnight. Each day they will remeasure the eggs, form a new hypothesis, and journal their conclusions. For a downloadable lab sheet, click on the link below:

Study Sessions

As you know, our pig dissections begin on Monday. I will hold after-school study sessions on Tuesday and Thursday so that students can ask questions and further examine their pigs before the test on Friday. I will remain at school until 5:30 to help students, but please consider sending a snack or money for the snack machines. I can't wait!

Piggy Week is Next Week!

Students will be exploring the human body by participating in a pig dissection next week. As you may already know, the organ systems of pigs are most similar to that of humans and are becoming a major resource for organ transplants. The dissection will take place Monday-Thursday, with a lab test scheduled for Friday. Each day, students will follow an instruction and question packet to guide them through the dissections. Each night, students should review the packet, as its content will make up the majority of the test.

Organ System Projects

This week students are presenting their organ system projects they've worked so hard to create. Students will present their digital presentation, explain their model and/or demo, and lead their classmates through the lab they created. All total, students will be instructing their peers for 20 to 30 minutes.

Eggcellent Eggsperiement

For the past week students have been learning about osmosis and diffusion through an egg experiment. Once the shell is removed, a raw egg serves as an excellent model of an animal cell. Students were able observe solutions of varying water concentration diffusing through the egg's membrane.

To conclude the laboratory experience, students will be spending the next week writing a lab report. Students may choose to present their data in the following formats: PowerPoint, Microsoft Word, Key Notes, 3-sided display board, or Pod Casting. The project will be completed entirely in class and should require no outside resources. To view the project components, click on the link below.
