- Science notebooks: print at 80% and glue a sheet into each student’s notebook after the lesson.
- Centers: the cut-and-paste sorts, like Solid, Liquid or Gas? and Animal Habitat Sort, work well for small groups.
- Hands-on days: pair Ice Cube Melt Race, Ramp and Car Experiment or Paper Tower Challenge with the Science Experiment Recording Sheet.
- Review: Space: True or False? and Observation or Inference? make quick exit tickets.
A plant unit in one week
- Monday: start the Bean Plant Journal and color The Life Cycle of a Plant.
- Tuesday: What Do Plants Need?, then set up a plant with water and one without.
- Wednesday: Parts of a Plant with a real flower to look at.
- Thursday: Plant Life Cycle Cut and Paste to check what they remember.
- Friday: measure the beans and compare the two plants.
Every topic has five sheets, so the same plan works for butterflies and frogs, weather or matter.

Questions
Are these science worksheets free?
Yes. All 50 worksheets, the ten topic packs and the answer key are free to print for home and classroom use, as many copies as your class needs.
Which grades are they for?
Kindergarten to 5th grade. Every sheet shows its grade range. The five senses, plant life cycle and butterfly and frog sheets start in kindergarten; the food chain, moon phase and variables sheets are for grades 3 to 5. Use the grade buttons to see only the sheets for your class.
Is there an answer key?
Yes. 31 sheets have a matching answer key page: the cut-and-paste sorts, matching, labeling, true or false and fill in the blank sheets. Each topic pack ends with its own answer pages, and every answer page is also in one PDF. Journals, experiment sheets and engineering challenges have no single right answer.
Do I need special supplies?
Most sheets need only a pencil, crayons, scissors and glue. The experiment and challenge sheets list what you need at the top: a bean and a zip bag, ice cubes, paper and tape, pennies, or a toy car and a few books.
What science topics do they cover?
Ten topics, five sheets each: plant life cycle, butterfly and frog life cycles, weather, solar system, habitats and adaptations, five senses, states of matter, simple machines and engineering, scientific method, food chains and ecosystems. They fit the life science, earth and space science, physical science and engineering units taught in most elementary schools.
Do the sheets print in black and white?
Yes. The headers are light colors that look fine in gray, and every diagram is a black outline kids can color. Sheets are US Letter and also print on A4.
All sheets are US Letter, print well in black and white, and are free for home and classroom use. More for teachers in the teacher resources library.
