Each of these labs are designed to take between 10-20 minutes of class time, leaving time for classroom discussion, introduction of important concepts, and other important supporting learning activities. Additionally, they use inexpensive, easy-to-find materials.
Lab reports are provided in both pdf (printable) and Google doc form to allow for teachers whose students have access to 1:1 devices to complete and submit their reports without paper. Also, this allows teachers to modify the activities to address their own classrooms and needs.
Some labs involve the construction of graphs or the manipulation of digital models. Students easily complete these activities by double clicking on the drawing in the Google doc and dragging and dropping the appropriate points or images around. This provides a quick and frustration free way for students to complete these important types of thinking activities.
Included in this package:
1. How to use these labs in Google docs with an LMS
2. Density and composition of pennies - Student lab and teacher notes
(Students use water displacement to find the density of pennies to determine that older pennies are composed of copper and newer pennies are composed primarily of zinc)
3. Rate of dissolving - Student lab and teacher notes
(A lab emphasizing experimental design and controls to draw conclusions about what factors speed up and which slow down the rate at which sugar dissolves in water)
4. How many molecules in a name? - Student lab and teacher notes
(Students design and carry out a procedure to find the number of formula units of chalk needed to write their name on a chalkboard)
5. How can we marble paper with shaving cream? - Student lab and teacher notes
(Students observe the effects of intermolecular forces between molecules and make claims about the attraction between different types of particles)
6. When does a reaction reach equilibrium? - Student lab and teacher notes
(Using graduated cylinders and straws of two diameters, students are introduced to reversible reactions and dynamic equilibrium)
