Life Science Reference Guide FREE - A quick reference guide for students covering the basic concepts in middle school life science. I like to print a class set in color and then laminate them for my students to use throughout the school year. I have also given the students a copy of this reference sheet to keep in their science notebooks/journals.
Water Density experiment for kids: drops of dye in cold water make pretty swirls, but in hot water they disperse quickly and color all the water. This is because molecules in hot water are moving more quickly than in the cold water.
Split a rib of napa cabbage and stick in dyed water. Food experiments help teach kids how their food grows and fuels them! can also be used to demonstrate how pesticides become the plant and how important it is to always eat organically grown high-water content produce.
FREE Lab: Use of Lab Equipment and Data Analysis Skills. This lab can be used with any type of science class that does lab work and with students in grades 6 through 12. I have found that my students come to me at the start of the school year with very different skill levels. I use this lab to insure that all students are quickly familiarized with my lab and learn (or review) how to use basic pieces of lab equipment.
