Every biology teacher is likely to need nutrient agar for a class at some point! It’s inevitable! I really like the dehydrated powders available from most biological supply companies, but sometimes you don’t have quick access or money in your departmental budgets.
Jessie Hoffman, a Fellow with the Woodrow Wilson Project, shared this link with me... A recipe that ingredients you can pick up at your local grocery store! The sources is www.eHow.com.

Sherry Makowski, Life Science Fellow with the 2010-11 cohort of the Woodrow Wilson Fellowship program, sent this link to the Nobel Prize Education site. Links here lead to lesson ideas and online games to support learning in all 5 of the areas for which the Nobel Prize is awarded.

Here’s a practical lesson idea to help teach about osmosis in cells!
I’ve adapted a lab that is available online from many different sources, and modified them specifically to address some key theories in science teaching:
The Essential Elements of Inquiry
The 5E Model of Instruction
Science Process Skills
There are 2 files you can download with this lesson!

There are several sites with labs in which students extract DNA from strawberries. This is one of the easiest, and it works very well!
The sources is the University of Washington, and the link below will download the pdf from their site!

This lab is my own adaptation of a lab I used years ago, with some updates in procedure.
Some teachers like to have students count cells on microscope slides. Others find that this is very difficult, so they use printed images. In this version, you can use either, or both, OR have students use images available on the internet.
This posting includes the lab packet, and two files you can download to use as pictures for use on a computer or to print. Please note that in my lab instructions, students are not told how to calculate the minutes in each phase or the number of wedges to fill in on the graph. This is deliberate, and requires students to some problem solving! You may need to help you class through this process, but I encourage you to make them think!

This inquiry-based activity lets students explore the effect of salt on the melting point of water... by making ice cream in a fun and simple way! Students collect data on the temperature of ice before and after adding salt! This is Dr. McConnell’s modification of a lab that can found at several locations on the web.

This lesson is one I use in my science education courses, and has been tried and tested with multiple grade levels and adults!
This could be used to explore chemical reaction rates, but is primarily intended to help learners experience the processes of science, the Nature of Science, and important factors in designing and conducting a science experiment.

This activity is a simple set of instructions for building an "air cannon" from a paper cup and a balloon or rubber glove. It's a miniature version of the larger air cannon I use in some of my classes to demonstrate vortex motion... a fun science toy, too!

This file is a template you can use as an assessment that asks students to journal or notebook the information they create and find during an inquiry lab. The file is flexible enough to suit any inquiry investigation.
When you print, select “print both sides - short edge binding” to get a file you can fold in half to make a small journal booklet.
