Science for your homeschool

By , founder of TheHomeschoolingCompany. Reviewed .

Your child asks a question, tests an idea, and learns to explain what the results show.

A lesson built around your child

An ecosystem is a network of relationships; changing one population can change energy flow, shelter, and survival across the whole system.

Lesson
A Forest Is Not Just a List of Species
Goal
Model energy transfer in a food web and predict how a targeted intervention could create both benefits and tradeoffs.
Science lesson "A Forest Is Not Just a List of Species": the lesson opening, its goal, and its project

How a lesson works

  1. A 10-minute reading

    This example lesson comes from the unit on energy flow, food webs, and ecosystem change. It moves from “Relationships carry the system” to “Interventions create tradeoffs” and builds to one idea: to understand an ecosystem, follow what moves between organisms: energy, matter, pressure, and opportunity.

  2. Help inside the reading

    If your child says a plant grew taller because it got more light, our Always-On Mentor can help them check what the comparison shows and what else might explain it. Your child can also highlight any line of “A Forest Is Not Just a List of Species” to ask about it or ask for a visual, and the mentor offers help on its own when they seem stuck.

  3. A check halfway through

    Your child answers “Why is a food web more useful than a simple list when predicting ecosystem change?” before reading on, and the Reading Check at the end asks new questions.

A project your child hands in

Choose a local or familiar habitat and propose one restoration action that improves conditions for a target species without ignoring the rest of the web.

Task
Use a food-web model and evidence from at least two sources to predict benefits, risks, and a way to monitor the outcome
Hand in
Food-web map plus a one-page restoration brief with monitoring indicators
Science assignment brief and written response in the learner's workspace

Questions parents ask

Where does my child start in Science?

Placement checks your child's current Science skills and sets the first lesson from that result, not from their grade.

How much of the teaching do I do?

None of it. The course explains each new idea and checks how your child uses it, while the mentor answers questions as they work. Every submission is graded as soon as it comes in, so you never grade it yourself.

Can I use the record for high-school planning?

Yes. The subject record holds every graded assignment with its written feedback, ready to export. We generate a transcript from the course records, ready for you to sign.

Science, taught around your child

A Science foundation that makes specialized courses more productive when the learner is ready.
