Black Hole Experiment Activity
A single-page hands-on activity using a magnet and paper clips as a physical analogy to demonstrate how black holes attract objects.
Fun with Chemistry: 20 Exciting Chemical Reaction Experiments For Kids
Introduce elementary students to basic chemistry concepts through 20 hands-on chemical-reaction experiments with explanations of the underlying science.
Human Impact on Ecosystems Inquiry Lab Experiment: Ecobottles Lab
An inquiry-based lab experiment ("Eco-bottle Lab") that has students design and run a controlled experiment testing how a human-caused factor (e.g., fertilizer, pesticide, road salt, acid rain, oil) affects a terrestrial/aquatic ecosystem, then write a formal lab report.
Newton’s 3 Laws of Motion – Lab Station Activity
Teach Newton's Three Laws of Motion through a rotating multi-station hands-on physics lab activity.
Answers included
Sink or Float Science Journal Experiment Worksheets Pre-K K
A hands-on science journal that guides young students through a sink-or-float experiment, teaching prediction (hypothesis), observation, and recording of results.
Science Research: Forces and Movement
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.
Paper Towel Absorbency Test – Scientific Method Lesson
Put scientific-method ideas into practice by comparing how much water different paper towels absorb. Students plan a controlled comparison, record measurements, calculate averages and use a graph to support their conclusion. Student notes and matched completed slides introduce variables and hypotheses beforehand, while an extension sheet suggests changing the liquid or measuring absorption time for a later investigation.
Apple Science Experiment - Sink or Float
Make learning about apples fun with this apple science experiment. Students will practice making predictions , conducting an experiment, and recording their results with this apple sink or float experiment. What is Included: There is a detailed instructional page that provides detailed instructions for the experiment, a materials list…
Properties of Water Science Lab
A hands-on inquiry science lab where students conduct three experiments (viscosity comparison, floating paperclip, water drops on a penny) to discover the properties of water: viscosity, surface tension, and cohesion.
Potential Energy Experiment Activity
Guide students through a hands-on physics experiment testing how the speed of objects rolling down an inclined plane relates to potential energy.
Quick + Easy Science Experiments
A packet of 4 hands-on science experiments using everyday classroom items, teaching young learners to make predictions and record observational data.
Race Car Science Lab
Teach or review the scientific method process through a hands-on ramp/toy-car experiment testing which fabric surface makes a car travel fastest.
10 Plant Experiments for Elementary School
A 90-minute biology lesson package guiding students through 10 hands-on plant experiments exploring how light, water, and soil affect plant growth.
Answers included
Crime Scene Investigation Student 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.
Soap Bubble Science Lab
A hands-on science lab that teaches or reviews the scientific method (hypothesis, variables, data collection, conclusion) using a soap-bubble comparison experiment.
Magnets Activity
Simple science investigation worksheet where students test and compare the strength of five types of magnets.
Free download Melting Ice Experiment | Water Unit Journal
Record what happens to ice left on a table using a simple observation journal. Children draw the ice before and after the observation period and complete an I observed response. Discuss what they notice rather than supplying the conclusion first. The page provides a way to compare two observations during a water or changing-materials lesson.
Back to School Activities | 10 Science Experiments & Investigations
Teach scientific-method thinking through 10 hands-on science experiments using common household materials.
Exploring Friction Graphic Organizer & Worksheet
Guide students through a hands-on friction experiment comparing the pulling force needed to move a wooden block across different surfaces, then reflect on results.
Skittle Diffusion Experiment
Demonstrate diffusion through a simple STEM experiment using Skittles candy, warm water, and a plate.
Apple Science Experiment - Observing Apples
Guide students through a hands-on apple observation science experiment where they predict and record what happens to apple slices stored under different conditions.
Photosynthesis Lesson, Worksheets, and Experiments for 5th, 6th, & 7th
A science resource introducing photosynthesis through a reading passage plus comprehension questions, and hands-on experiments (seed germination/light exposure, chlorophyll extraction, and at least one more experiment) to reinforce the concept.
Answers included
10 Edible Science Experiments for Elementary Students
An edible/hands-on science activity guide presenting 10 kitchen-based experiments that teach science concepts (e.g., density, acid-base reactions) through food-safe materials.
