Science: How Solids Become Liquids
Second graders discover how matter changes from one state to another by observing melting ice cubes. They decide on means to warm the ice and predict what will happen. Students record how long it takes for the cubes to melt.

Estimating Altitude of Water Cloud Base
Students conduct an experiment to determine dew point and use a formula to detemine altitude. They construct a chart and predict what altitude clouds would form, given the dew point on the ground.

Science-Unit on Matter-Gases
First graders understand that gases take up space even though you can't see or smell it. This is done through many experiments like trapping air in different sized bags, using balloons and plastic bottles, and blowing bubbles. They...
Curated OER
Properties of Liquids
Seventh graders explain that liquids are made up of tiny particles and how these spaces allow other particiles to fit in between larger particles. They then plan and carry out simple scientific experiments.

Heat and Matter
Students explore liquids and solids by conducting in class experiments. In this matter instructional activity, students define the properties of matter and how heat can change those properties. Students experiment with heating objects...
Cornell University
Atomic Bonding
Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

Sound Waves
How does sound travel through different mediums? Scholars explore this question by creating and observing sound waves as they learn the difference between transverse and longitudinal wave motion. Using their new knowledge, class members...
Curated OER
Temperature
Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...

Happy Landings: A Splash or a Splat?
Huygens spacecraft landed on Saturn's moon Titan in 2005, making it the farthest landing from Earth ever made by a spacecraft. In this hands-on activity, the 12th installment of 22, groups explore how density affects speed. To do this,...
LABScI
Acoustics: The Sound Lab
If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels. Whole...

Study Soil
What's in soil? Young scientists study the pH levels of soil from their school yard. They observe the land and area the soil came from to decide if location has anything to do with acidity level.
Cornell University
Density
Certain things just do not mix, including liquids of varying densities. Learners collect data to determine the densities of several liquids. They then use the density information to predict the type of liquid.
