In 8th grade this week we investigated various chemical reactions. Students were looking for signs on whether a chemical reaction occurred or not. The signs include gas formation, formation of a precipitate, an unexpected color change, and a change in temperature. Here are a few photos of the student conducting the investigations:
Ms. Jessica Yates
- 6th-8th Science Teacher
- Hello! Welcome to the Middle School Science page. I believe science is best learned in a hands-on approach, which allows for the scientific mind to really develop. I encourage students to always ask questions and question the world around them. I have high expectations for my students and will ensure they receive the proper tools for success, not only in my class but for the future.

What's Happening in 6th-8th Science
This week the 6th and 7th graders learned how to use a microscope, how to focus a prepared slide, and how to make their own slides. Each student made an iodine stained cheek cells slide – using their own cells! Some students even made slides using their own hair and eyelashes. Students were fascinated with what they saw. Below are a few pictures from the investigation:
At the beginning of the school year, basic science skills and safety are reinforced in 8th grade through conducting the “Rainbow Lab.” Students must be precise in their measurements using a graduated cylinder and beakers. Effective group work is also essential and was a focus for the “Mealworm Races” conducted in 6th and 7th grade. Below are some pictures of the various investigations.
I hope everyone enjoyed their summer break and is fully rested for another amazing school year. 6th graders – it was wonderful to met some of you over the summer and investigate Mars. I look forward to meeting the rest of you this week. Get excited for our week long trip to Yosemite in April! 6th and 7th graders – begin thinking of a scientific question to investigate for the science fair that is held in January. 8th graders – here’s to an outstanding last year learning chemistry and physics.
See everyone on Thursday and Friday,
6th Grade: Have been working hard on creating a volcano documentary. Groups have gotten very creative and even made up entire songs about their volcanoes. They will finish the year by creating a biome diorama and presenting them to the class.
7th Grade: Just started a research paper on the evolutionary history of a species of their choice. They are gaining in-depth knowledge about how evolution works and also refining their researching skills.
8th Grade: Are making a physics video lab in replace of a written lab write-up. Groups are investigating questions on speed, velocity, acceleration, and forces.
Looking forward to a fun end of the year!

We also take a field trip to the Exploratorium in 8th grade – see a previous post about a past trip!
The first quarter of the school year is coming to a close on Friday October 27. Here is a summary of some topics and projects we have discussed so far:
6th Grade: investigation on density, Earth’s natural resources (created a comic strip), investigation on whether or not rocks absorb water, weathering (types – mechanical and chemical), soil (students brought in a soil sample to learn more about), erosion, and deposition. Below are images showing students collect data on various objects to determine what density is.
7th Grade: how to use microscopes (viewed cheek cells, Elodea under fresh and salt water), cell structure and function (students drew analogous structures to represent animal cells), investigating why does eating popcorn cause ones lips to dry out (osmosis and diffusion), and where does most of a plants mass come from. Below are images showing students viewing microscopes and collecting data.
8th Grade: reviewed safety and accuracy when conducting experiments, how heat transfers, learned the various states of matter (solids, liquids, gases, plasma), state changes, and an introduction to atoms and the periodic table. Below are images showing students conducting a rainbow lab and focusing on working together and following directions exactly.
Looking forward to the rest of the year!
Over the last two weeks some students came back to NDV for a math review and science enrichment. For the math review, students went over basic foundational skills involving decimals, fractions, proportions, and algebra. One group of students investigated what would happen when people are presented with a calorie food menu vs. an exercise food menu – would they change their order and choose healthier options once they saw how long they would have to exercise? Another group calculated the number of minutes people would have to exercise depending upon the restaurant and the exercise they conducted. The last group of students investigated whether the International Olympic Committee should change racing events so that distances are proportional to athletes heights. Below is an image of each group presenting and sharing their results to the class – they all did an amazing job.
For science enrichment, students learned about roller coasters through creating their own paper roller coasters. We watched videos and discussed the fundamentals of potential energy, kinetic energy, and speed. Once the roller coasters were completed, students conducted a speed experiments to calculate which parts of the coaster were the fastest. Below are a few images of groups with their roller coasters.

Ecology Club Meetings: about twice a month, during Middle School lunch (schedule TBA)
Any Middle School student may join Ecology Club at the beginning of the school year. Members should have a love of the environment and a passion for making the world greener. We will do various environmental friendly projects throughout the year. Members are also in charge of the recycling and compost program at NDV.
Focus: spread the message of reducing waste and re-instill a love of nature to members!
Last week the 8th graders went to the Exploratorium for the day. They had a wonderful time and learned a lot. Some favorite activities were the brain games against each other.
