Diffusion Of Molecules

Students conduct a series of experiments to observe factors that impact molecular movement. In this molecular chemistry lesson, students drop food coloring in water with different properties (hot, with ice, with alcohol) and observe how...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common compounds.

Learners list reasons why water is important and investigate and graph the freezing points of different solutions.

Scientific inquiry activity where students investigate how molecules move in liquid. They will observe that molecules in liquid move in a random manner and that heat will increase and cold will decrease the speed of molecular movement in...

Students investigate how heat affect sugar solutions. For this science lesson, students compare the sweetness of different types of sugars. They research the development of sugar and create a timeline.

Who needs a compass to find cardinal directions? Just place a stick in the ground and record the movement of its shadow over the course of a day. Then, measure the shadow lengths in order to determine a north-south line. A simple...

In this chemistry lab, young scholars investigate whether water molecules have any space between them by filling a glass with water, and adding salt without the water overflowing. They will also experiment with the temperature of the water.

In this chemistry field/class based activity, students investigate snow and, more specifically, why snowflakes have six sides. Students will individually fossilize a snowflake and observe similarities and differences with other members...

Students study the process for diffusion of molecules. In this chemistry lesson plan, students understand molecular movement, develop skills for a chemistry investigation, develop skills in making hypotheses, develop observational...

Students study three different muscle types and investigate the affect of space travel on astronauts' muscles. They examine how exercise has a positive affect on muscle both on Earth and in space while looking at engineers' roles in...
