Explore how cells can only be so big by studying how things move in and out of them, and discover why the size of a cell is connected to its surface area and volume.
In this lesson, students will extract chlorophyll from spinach leaves and make different concentrations following the dilution method. Students will learn to compare the absorbance values obtained at
This lesson is an activity to see what an angle is and how is can be used to approximate the time of day or even navigating vessels by measuring other celestial bodies. Students will use sextants to
In this high school science/engineering lesson on exploring cracked steel, students will delve into the concept of cracked steel and its impact on structural integrity. They will define composites and
I use this lesson as a fun activity to visualize unit conversions and the immense scale of the universe. I love this lesson because I find it challenging to teach unit conversions with hands-on
Students will be divided into 6 groups, one for each of the major systems in the human body, and create a presentation to share with the rest of the class.
Students will focus sunlight through a pinhole onto a sheet of paper. Knowing the distance between the projection and the pinhole allows students to calculate the diameter of the Sun using ratios.
In this lesson students will discover the best angle that will produce the fastest speed for a hot wheel vehicle when traveling 1 meter. Students will also practice calculating speed (speed=distance
Students will be able to understand proportional relationships with rescaling a drawing. Students will be able to draw a reduced scale drawing and enlarged scale drawing in the end. Students will also
