Provide hands-on science experiments and activities across physical, earth, and life science topics for grades 3-4, supplementing the (U.S.) National Science Education Standards.
A blank student investigation worksheet guiding a hands-on experiment testing how the surface a toy car rolls onto affects the distance it travels, to teach the concept of friction.
A 90-minute biology lesson package guiding students through 10 hands-on plant experiments exploring how light, water, and soil affect plant growth.
Simple science investigation worksheet where students test and compare the strength of five types of magnets.
Demonstrate diffusion through a simple STEM experiment using Skittles candy, warm water, and a plate.
Teach elementary students the basics of static electricity through a set of simple, safe hands-on experiments.
Guide students through a hands-on science experiment testing the absorbency of different types of paper, recording predictions, method, results, and a conclusion.
This Water Cycle Experiment Worksheet is a great resource for students to use to conduct their own experiment on the water cycle. By doing this experiment, students will have a better understanding of how the water cycle works. This worksheet is a great tool for teachers to use in their classrooms.
An introductory photosynthesis lesson for elementary science, teaching how plants make food using sunlight, water, and carbon dioxide, paired with a hands-on seed-germination experiment comparing plant growth in light vs. dark.
Teach scientific-method thinking through 10 hands-on science experiments using common household materials.
A 23-chapter set of hands-on science labs and activities exploring water science topics for upper elementary/middle school students: water pressure, buoyancy, chemistry, surface tension, ice, purification, conservation, weather, and water's role in life.
Teach environmental science concepts (pollution, water quality, ecosystems, recycling, population, energy conservation) through hands-on labs framed as 'lab team' investigations.
Teach 9-12 year old students earth science concepts (earth structure, landforms, rivers, coastal landscapes, oceans) through a photocopiable activity and experiment booklet.
A single-page hands-on activity using a magnet and paper clips as a physical analogy to demonstrate how black holes attract objects.
Multi-file science mini-unit teaching mechanical, potential, and kinetic energy through direct-instruction and hands-on lesson plans, a slideshow presentation, and a model-building lab activity.
A 9-day cross-curricular (science-based) crime-scene-investigation unit in which students act as detectives to solve a staged classroom 'crime' using forensic-style experiments.
Introduce elementary students to basic chemistry concepts through 20 hands-on chemical-reaction experiments with explanations of the underlying science.
In-depth teacher background/theory guide on plant biology (seed anatomy, germination, root systems, photosynthesis) paired with embedded fill-in-the-blank student journal prompts and classroom experiment suggestions, intended to support a plant life-cycle observation unit.
Guide students through a hands-on physics experiment testing how the speed of objects rolling down an inclined plane relates to potential energy.
Provide a collection of hands-on science experiments/demonstrations (chemical reactions, physical science, sensory play) for elementary students to try with adult-supplied household materials.
Free download A collection of simple hands-on science experiments (e.g., mini tornado in a bottle, balloon rocket, bridge building challenge, mini parachute), each paired with a student scientific-method worksheet template.
The lesson begins with two tomato plants treated differently in more than one way, prompting students to discuss why the conclusion is unreliable. Fill-in notes introduce independent, dependent, and controlled variables before students apply the terms to basketball, studying, and a derby-car scenario. A short review and model answers support the follow-up discussion.
Students predict which balls will need the most and least blowing to begin rolling, then record observations for up to six balls on soft-to-vigorous scales. Two recording pages provide hypothesis, experiment, outcome and conclusion sections. Compare results with predictions and discuss the limits of the test: different balls vary in several properties, so these qualitative observations do not isolate the effect of weight, size or texture alone.
Provide a hands-on home/troop science activity booklet (aimed partly at Girl Scout leaders) teaching kitchen-based science concepts such as density through experiments.
