Scientific Method Drops on a Penny Experiment
Quick and easy experiment to introduce or review the steps of the scientific method. In this two part lab activity, students investigate how many drops of water will fit on the surface of a penny. They then choose one variable to change and repeat the experiment and see how their changing variable affects their results. Covers the following steps of the scientific method: Asking a question, creating a hypothesis, performing an experiment and collecting data, analyzing data and drawing conclus

Lab Safety Rules Poster Assignment
This is the directions and rubric that I give to my students for their beginning of the year Safety Poster assignment. This is a great assignment for a few reasons: it makes for perfect classroom décor early in the school year and for Back to School night, it really drives home the Safety Rules because students are surrounded by them hanging around the classroom, it gives you a chance to read students’ writing early on in the school year, and it’s an easy grade for which most students do well–

Laboratory Safety Activity - The What Not To Do Lab!
Presented here for your enjoyment is the What-Not-To-Do-Lab, a demonstration of just how bad it can get in a science classroom when safety procedures are not followed. Students are given a cartoon where 36 separate lab accidents are happening simultaneously. They are asked to identify exactly what went wrong, and possible future consequences. An chance for students to demonstrate their knowledge of safety procedures without endangering themselves or others!

States of Matter and Phase Change Diagram Lab
This lab is relatively simple. Students investigate the relationship between states of matter and temperature. Students simply see what happens to the temperature of a substance as you melt ice. Many students think it will be a steady increase and do not realize there will be flat parts to the graph.
By the end of the lab students graph will graph the data they collected. If students have collected data carefully, then it should look like a phase change diagram. To spruce things up in the

It's a Gas! Gas Laws Activity
Kinetic Molecular Theory never looked so good! Be prepared to use this activity as a touchstone, introductory activity that you can reference as you build gas behavior knowledge in Gay-Lussac's Law, Boyle's Law, and Charles' Law. It's a Gas! is an introductory, kinesthetic activity to learning about the variables that affect air pressure. Your student will become one with the molecules. In fact, they ARE the air molecules in this experiment! Yes, your students will think you have gone mad.
