If you are planning your freshman’s 1st year high school science subjects you are in the right place for loads of great information and resources. And look at my page How to Choose the Right Homeschool High School Science for more fun teen ideas

Starting high school science at home can feel both exciting and intimidating. Ninth grade marks the transition from middle school’s broad, general science into deeper, more formal studies.

This is where students begin learning science in a structured way with labs, textbooks, and connections to math and critical thinking.

A Beginner's Guide To 1st Year High School Science Subject

Because you’re homeschooling, the good news is that you don’t have to do it exactly like a public school.

You can choose the path that fits your student’s interests, abilities, and future plans, while still giving them a strong academic foundation.

The first year of high school science is about building a foundation, not perfection. Whether your homeschooler starts with Biology, Physical Science, or Earth Science, the goal is to nurture curiosity, critical thinking, and confidence. 

With the right balance of structured lessons and hands-on exploration, your student will be well-prepared for Chemistry, Physics, and advanced sciences in the years to come.

WHAT MAKES HIGH SCHOOL SCIENCE DIFFERENT

High school science is usually taken in a 3- or 4-year sequence, often beginning with Biology.

Colleges expect to see at least three lab sciences on a transcript: Biology, Chemistry, and Physics. Some students also add Earth Science, Environmental Science, or Anatomy.

I have put together a beginner’s guide to 1st year high school science for homeschoolers.

I’ve included course options, typical topics, and helpful tips for making science engaging and doable at home, whether you are looking for the basics, family style, or advanced.

The first year sets the tone. It teaches students how to write lab reports, use scientific vocabulary, and connect science with real-world problems.

More importantly, it helps them gain confidence for the harder courses that come later.

  • Moving into high school science comes with a few big changes:
  • Critical Thinking & Application – The focus shifts from memorization to analysis, reasoning, and problem-solving.
  • More Formal Labs – Students should learn to follow lab procedures, record results, and write reports.
  • Math Skills Matter – While Biology requires less math, Physical Science and Chemistry rely on equations.
  • Textbooks or Online Curriculum – Students begin reading and learning from structured resources.

COMMON 9TH GRADE SCIENCE OPTIONS

 (The most common choice)- Biology is the study of life in all its forms, from tiny bacteria to giant ecosystems.

BIOLOGY

Most schools (and many homeschoolers) choose this as the 9th-grade science course because it doesn’t require advanced math skills.

Suggested Biology Curriculum:

A Beginner's Guide To 1st Year High School Science Subject

Topics Covered in Biology:

  • Cell Biology- Learning the structure and function of cells, DNA, and organelles.
  • Genetics- How traits are passed on, Punnett squares, DNA replication, and mutations.
  • Evolution & Classification- How species change over time and how organisms are grouped.
  • Plants & Photosynthesis- Plant systems and how they make food using sunlight.
  • Human Anatomy & Physiology- Overview of the body’s systems and how they work together.
  • Ecology- Relationships between organisms, food chains, and environmental impact.
  • Lab Work- Microscopy, osmosis, DNA extraction, and optional dissections.

* If dissections aren’t appealing, many curriculum providers offer virtual labs, detailed diagrams, or alternatives using models.

PHYSICAL SCIENCE

Physical Science introduces students to basic physics and chemistry concepts.

Some families choose this as a steppingstone before moving into Biology, Chemistry, and Physics, going more in depth than they did in elementary.

Suggested Physical Science Curriculum

Topics Covered in Physical Science:

  • Matter & Atoms – Building blocks of matter, atomic structure, and molecules.
  • The Periodic Table – How elements are organized and why their properties matter.
  • Forces & Motion – Newton’s laws, gravity, and everyday applications like cars and sports.
  • Energy – Heat, electricity, magnetism, and conservation of energy.
  • Waves & Sound – The science of light, sound, and wave properties.
  • Intro to Chemistry – Simple reactions, acids and bases, balancing equations.

*This course pairs well with lots of hands-on activities—baking soda and vinegar reactions, balloon rockets, homemade electromagnets, and simple circuits.

EARTH & SPACE SCIENCE

Earth Science can also serve as a 9th-grade option, especially for students interested in astronomy, geology, or environmental studies.

Suggested Earth & Space Curriculum

Topics Covered in Earth Science:

  • Earth’s Structure – Layers of the Earth, plate tectonics, earthquakes, and volcanoes.
  • Rocks & Minerals – Identifying rocks, understanding the rock cycle, and practical uses of minerals.
  • Weather & Climate – Clouds, storms, air pressure, and climate change basics.
  • Oceans – Tides, currents, and marine ecosystems.
  • Astronomy – Solar system, stars, galaxies, and space exploration.
  • Environmental Science – Human impact on ecosystems and sustainable living.

*Earth Science is a fantastic choice if you enjoy outdoor learning. Rock hunts, stargazing, weather journals, and local field trips make this subject come alive.

Finally, look at these general tips.

FIRST YEAR HIGH SCHOOL SCIENCE TIPS

  • Keep Records- Save lab reports, quizzes, and grades to build a strong transcript
  • Pick the Right Starting Point- Biology is the most common, but if your student struggles with reading-heavy material, starting with Physical Science might be better.
  • Don’t Stress About Labs- Simple kitchen science, microscope kits, or online virtual labs count! Keep lab notebooks as part of your transcript.
  • Encourage Independent Learning- High school teens should begin taking responsibility for reading, note-taking, and managing assignments.
  • Use Resources Beyond the Textbook- Documentaries, YouTube science channels, podcasts, and local science museums make learning engaging.

5. CHECK YOUR LOCAL LIBRARY

Some lab items, like microscopes, are available to check out at your local library at no cost.

Next, look at this list organized by supplies.

BEGINNER’S GUIDE TO BIOLOGY LAB SUPPLIES

Before handling a microscope or dissecting a frog, ensure you have the proper safety gear.

SAFETY EQUIPMENT

Even small-scale experiments require protection. Teach your student proper lab safety rules before beginning any experiment.

  • Safety goggles– Choose impact-resistant goggles that fit comfortably over glasses if needed.
  • Gloves-Nitrile or latex-free gloves protect against chemicals and biological specimens.
  • Lab coat or apron- Keeps clothing safe from stains or damage.
  • First aid kit- Accidents happen, so have bandages, antiseptic wipes, and burn gel handy.
  • Ventilation – If your experiments involve fumes (like formaldehyde in preserved specimens), use a well-ventilated space or a small fume hood.

MICROSCOPE & ACCESSORIES

A good microscope is the heart of a biology lab. High school biology often requires viewing cells, microorganisms, and prepared slides.

An Easy Beginner’s Guide to Biology Lab Supplies High School
  • Compound microscope– Look for one with at least 400x magnification (1000x is better for bacterial studies).
  • Prepared slide set– These often include samples of plant tissue, insect parts, animal cells, and bacteria.
  • Blank slides & cover slips– For making your own samples.
  • Stains & droppers- Methylene blue and iodine are common for highlighting cell structures.
  • Lens paper- To clean optics without scratching them.

If budget is a concern, a mid-range microscope can last all through high school and even into college-level work.

Avoid the very cheap models, as they often give blurry results and frustrate students.

DISSECTION SUPPLIES

Dissection helps students learn anatomy and understand how organs work together.

Most high school biology courses include at least one unit on it whether it is human anatomy or marine biology.

An Easy Beginner’s Guide to Biology Lab Supplies High School
  • Dissection kit-Should include scissors, scalpel, forceps, probe, and pins.
  • Dissection tray & pad– Hold the specimen steady while protecting your work surface.
  • Specimens– Common options are frog, fish, earthworm, and cow eye. Buy preserved specimens individually or as a set.
  • Gloves-  Single-use nitrile gloves are a must for handling specimens.

Some students are squeamish about animal dissection. You can substitute with virtual dissection software or models.

GENERAL LAB TOOLS

Beyond microscopes and scalpels, biology experiments often require simple but useful tools.

Having these on hand means you can do everything from growing bacteria cultures to testing plant pigments.

An Easy Beginner’s Guide to Biology Lab Supplies High School

CHEMICALS & BIOLOGICAL MATERIALS

You’ll use chemicals for staining slides, testing for starch, or extracting DNA from fruit. Always store them safely.

An Easy Beginner’s Guide to Biology Lab Supplies High School

Common biology chemicals include:

  • Methylene blue (cell staining)
  • Iodine solution (plant starch test)
  • Hydrogen peroxide (enzyme experiments)

MARINE BIOLOGY BOOKS FOR HIGH SCHOOL

First, look at some of these books to add to your marine science experiments.

8 Marine Biology Books for Teens

Choose a few of these ocean themed books to go along with your study of the Oceans. Whether you're looking for a spine for a unit study or literature, you'll love this roundup.

Marine science helps students understand how oceans shape our planet. The ocean regulates weather, supports diverse food webs, and produces more than half of the oxygen we breathe.

Too, marine science develops skills in critical thinking, data collection, and observation, which are core components of scientific inquiry.

Further, marine science doesn’t require a full lab or ocean access—just creativity. High school students can design their own experiments using basic household items, record their observations, and discuss their findings.

Encourage them to keep a lab notebook, take photos of each stage, and connect their results to real-world marine issues like coral bleaching or pollution.

MARINE SCIENCE EXPERIMENTS FOR HIGH SCHOOL

Now look at some marine science experiments.

There are many fun hands-on experiments out there that your high school teen can perform to learn about the ocean and the life within.

 For our marine biology this year, the main one we opted for was Marine Biology Dissection Specimens and another kit we had to investigate firsthand the structure inside and out of a few ocean creatures.

We also added a Dissection Kit because our specimens did not included any tools.

Our specimens included a dogfish shark, a starfish, a clam, as well as Brine shrimp eggs, a natural sponge, a coral specimen, and dried sea fireflies.

I am going to give you a few ides for how to experiment each one.

Dogfish Shark- The dogfish shark is a small species of shark commonly used in marine biology because it’s easy to handle and offers a clear view of many organ systems.

  • Examine the gills-note how water flows over them to extract oxygen.
  • Follow the path from mouth to stomach to spiral intestine and learn how this carnivorous fish digests its food.
  • How do a shark’s adaptations-like fins, teeth, and sensory organs—show careful design for life as a predator?

Starfish- Starfish, or sea stars, are incredible examples of regeneration and radial symmetry.

  • Observe the five arms radiating from the center and locate the tiny tube feet underneath.
  • Water Vascular System: This unique system controls movement and feeding using water pressure, an amazing engineering feature.
  • Discuss how starfish can regrow lost arms, and what that says about resilience in marine ecosystems.
  • Dissect one arm to trace how the water vascular canals extend through the body.

SCIENCE EXPERIMENTS FOR TEENS

Clam- The clam gives students a look at mollusk anatomy—creatures that live inside protective shells and use muscular feet to burrow into sand or mud.

  • Examine the two shells (valves) and the strong hinge that keeps them closed.
  • Inside, identify the gills, foot, and mantle.
  • Clams are filter feeders; watch how their gills are designed to trap tiny food particles from the water.
  • Have students sketch the clam’s internal organs and label each part. Compare how a clam’s slow, protected lifestyle contrasts with the active dogfish shark.

Coral- Coral might look like a rock, but it’s actually made of tiny living animals called polyps that build calcium carbonate skeletons.

Explore why coral reefs are threatened by pollution and climate change, and brainstorm small ways your family can help protect marine life.

Use a magnifying glass to examine the tiny holes where polyps once lived.

Discuss how coral reefs are biodiversity hotspots, providing shelter and food for countless species.

Marine Science Experiments For High School Made Easy

MORE MARINE SCIENCE EXPERIMENTS FOR HIGH SCHOOL

Marine Biology and Ecosystems

  •  Use a clear 2-liter bottle, gravel, saltwater, small plants, and brine shrimp or snails to create a small self-sustaining ecosystem.
  • Add layers of sand and gravel, fill with saltwater, and include small aquatic plants.
  • Introduce tiny marine animals and observe how they interact over time.

Students learn about food chains, oxygen production, and how ecosystems rely on balance to survive.

Ocean Acidification and Chemistry

  • Fill two jars: one with plain water and one with vinegar.
  • Place seashells or bits of chalk in both.
  • Compare how they change over several days.

This simulates how increased carbon dioxide in the atmosphere leads to more acidic oceans, harming shell-building organisms like coral and clams.

Marine Pollution and Environmental Science

  • Fill a container with water, add a few drops of vegetable oil, and try to clean it using cotton balls, spoons, or dish soap.
  • Experiment with different methods and record which works best.

This activity helps students understand how difficult it is to clean up oil spills and the importance of prevention and environmental care.

  • Watch ocean documentaries (like Blue Planet or The Deep).
  • Explore virtual marine labs or ocean databases (NOAA, Smithsonian Ocean Portal).
  • Research marine careers—biologists, oceanographers, and conservationists.

Sciencing has rounded up some great ideas for lab activities, experiments, and college credits.

Next, look at a few facts about our marine biology spine.

WHY CHOOSE OCEANS BY MASTERBOOKS

First, a bit about MasterBooks’ Oceans, it is a beautifully designed, marine biology course suitable for high school students.

Topics Include:

  • Ocean currents and tides
  • Marine ecosystems
  • Marine animal classifications
  • Coral reefs
  • Deep sea exploration

It’s a full-credit science course with a built-in schedule, comprehension questions, and quizzes.

It is ideal for homeschoolers who appreciate structure but still want the freedom to go deeper.

How To Combine High School Homeschool Marine Biology Curriculum & Notebooking

The teacher’s manual includes premade worksheets that cover questions, vocabulary, and more.

Then look at why we paired this spine with notebooking.

WHY USE NOTEBOOKING WITH MARINE BIOLOGY CURRICULUM

Notebooking is an open-ended, student-created method of recording learning through written narration.

But also it can include illustrations, diagrams, maps, charts, and more.

It encourages critical thinking, research, and creative expression.

While it is a great curriculum, it did not delve as in-depth into marine animals as I had hoped.

To round out this study, I assigned twice-a-week notebooking pages on the animal of their choice in addition to their suggested format.

This could include printed photos from the internet, drawings, watercolors and information like food sources, fun facts, and more.

Grab a 3-ring binder and assign categories for the dividers to keep throughout your study to expand on Masterbooks Oceans.

Let your student design a cover for it by hand or by creating one online and printing it out.

2. Follow the Schedule in the Spine then expand on it.

Each week, follow the MasterBooks schedule for reading and assignments. After your student completes the reading:

MARINE BIOLOGY NOTEBOOKING WITH A TEEN

  • Have them narrate or summarize what they learned in their own words.
  • Encourage illustrations (like labeling parts of a jellyfish or drawing the ocean zones).
  • Use diagrams, charts, or even infographics to represent data.

3. Add Research-Based Notebooking Projects

Let your teen dive deeper into topics of interest through independent research. Encourage them to create full notebooking pages on:

  • A specific marine animal (e.g., cuttlefish, humpback whale)
How To Combine High School Homeschool Marine Biology Curriculum & Notebooking
  • Bioluminescence in deep-sea creatures
  • Coral bleaching and conservation
  • The physics of sonar and whale communication
  • Biblical references to oceans (like Genesis, Job 38, or Psalm 104)

These can be added weekly or monthly, and you can turn one of them into a final presentation or project.

4. Include Hands-On Learning & Fieldwork

  • Virtual field trips (Monterey Bay Aquarium, NOAA deep sea dives)
  • Local aquarium visits or tide pool exploration
  • Ocean-themed experiments (density layering, salinity tests, ocean current models)
  • Journaling observations from a trip to the beach or a documentary viewing
  • All of this can be recorded in the notebook with photos, drawings, and written reflections.
How To Combine High School Homeschool Marine Biology Curriculum & Notebooking

5. Use the Notebook for Review and Assessment

Notebooking pages make a great informal review tool. Before a quiz or test, have your student do one or more of the following…

  • Flip through their notebook
  • Highlight key terms
  • Create a “review summary” page with bullet points or diagrams

This reinforces memory and builds study skills without requiring rereading the entire text.
