K-5th Grade HOPES Activity Manuals

 
K-5 2nd Grade- Plants 

 
In this module, students investigate the question “What variables affect plant growth?” in order to learn that plants need water and light to live the longest life. For their initial observation, students are shown an experiment to test how soil type affects plant growth and learn that soils that do not absorb water will not aid plant growth because they are unable to provide water to the plant. Upon designing their group experiments, the variables that they are able to investigate include water amount, nutrient amount (sugar, salt, or fertilizer), or light amount. In their first module, students are taught to use graduated cylinders and will use this technique in this module as well. To assist the students in precise measurements of the plants, they are taught how to measure in millimeters using a ruler. The scientific practice this module focuses on is observations, including whether a statement is an observation, inference, opinion, or incorrect observation. Activity courtesy of HOPES 2014 Recipients SciTrek.

K-5 3rd Grade- Mealworms

 
In this module, students investigate the question “What variables affect the direction a mealworm travels?” in order to learn that in particular habitat changes an animal will either move, die, or adapt. For their initial observation, students are shown an experiment to test whether a mealworm will travel to dry woodchips or wet woodchips to learn that mealworms live in a dry environment. Upon designing their group experiments, the variables that they are able to investigate include food type, bedding type, light amount, number of holes to travel through, and color of environment. Students are taught the importance of running multiple trials of their experiment and the importance of finding one number to represent the outcome of the trials. Because of this, students are taught to find the median of a given set of numbers and use this skill to report the median from their own experiments. The scientific practice this module focuses on is questions, including whether a question is testable or not testableActivity courtesy of HOPES 2014 Recipients SciTrek.

K-5 Getting 4th Graders Excited about the
Cardiovascular System
 

 
This activity series focuses on contributors to a healthy lifestyle; exercise and eating right, while learning human physiology. Students will use the scientific method to test the effects of exercise on heart rate, respiration rate and blood pressure. Activity courtesy of HOPES 2011 Recipients Dr. Patricia Halpin, Scientists & Heather Cantagallo, Teacher.

K-5 5th Grade- Chromatography

 
In this module, students investigate the question, “What variables affect the smear?” in order to learn about physical properties of substances. For their initial observation, students are shown an experiment in which a black dot is placed on a piece of paper, the paper is placed in a test tube of water, and as time passes the water rises and the black dot smears up the paper and separates into different colors showing students that black ink is a mixture made up of several different colors of ink and the mixture can be separated. Upon designing their group experiments the variables that students may choose from include but are not limited to pen color, pen type, liquid type, liquid amount, paper type, dot height, dot size, and time. The scientific practice this module focuses on is conclusions, including identifying statements as claim, data, or neither as well as identifying appropriate claims and data based on given results. Students in this module are able to design two experiments, the first changing up to three variables and the second changing one variable. Students are given the option to change multiple variables in order to learn that valid conclusions are only able to be made when there is one changing variable.Activity courtesy of HOPES 2014 Recipients SciTrek.
