This is lesson 3 of 3 in the Goldilocks’ Café Just Right unit. This lesson focuses on systematic investigation on getting a cup of coffee to be the “just right” temperature and turbidity level. Students will use both the temperature probe and turbidity sensor and code using ScratchX during their investigation.

This is a lesson plan that will help students to understand that the Law of Conservation is applicable to all systems in nature, including their cell phone that they use regularly. It means that energy, though it might seem to have been created or destroyed, is actually conserved, but simply transformed from one form to another.

In this lesson, students will review the basic ideas of heat, the direction it flows, and the results of this flow on the kinetic energy and expansion of the particles. Students will investigate this concept in a 5E lesson format using claim, evidence, reasoning in their conclusion. They will determine how different temperature water baths effects the ease/difficulty of opening jars with tight fitting lids and link these results to the knowledge that heat flows from warmer to cooler materials. Applying the knowledge that increasing the amount of heat of the matter will increase the kinetic energy of it's particles, will result in expansion of that matter. Because each type of matter has a different coefficient of expansion, the amount of expansion will vary in different materials. Students will realize that a jar with a tight fitting lid may loosen if hot water is applied.

Using a guided-inquiry model, students in a math or science class will use an experiment testing the effect of temperature on cricket chirping frequency to teach the concepts of representative vs random sampling, identifying directly proportional relationships, and highlight the differences between scientific theory and scientific law.

Type: Lesson Plan

This activity allows students to experiment with balloons. Students are given basic instructions to blow up and pop a balloon wearing goggles. Students will make observations and come up with testable questions. A lesson is given on the different types of variables. Students then design an experiment coming up with the testable question and identifying the variables. The idea behind this lesson is not for the student to conduct the experiment and collect the data, but that is a possible extension.

Type: Lesson Plan

In this lesson, students will predict if the temperature will rise inside of an empty sock compared to the air outside the sock then they will test their hypothesis. This lesson addresses heat transfer and variables.

Type: Lesson Plan

Students will conduct a simple laboratory experience that practices the proper use of controls and variables. Students will conduct a controlled experiment in their laboratory groups.

Learn to identify the independent variable and the dependent variable in an experiment with this interactive tutorial.

Type: Original Student Tutorial

Students are asked to design an experiment to answer an experimental question. Students should identify a control group, dependent and independent variables and possible outcomes or what type of data would be gathered. Students are not actually performing these experiments but will need to explain their investigations.

This informational text resource is intended to support reading in the content area. The article describes two studies that show how the decline of large sharks has adverse effects on other organisms in their food web. The article explains that without apex predators like sharks, other large fish and rays tend to thrive and prey too heavily on shellfish populations.

This informational text resource is intended to support reading in the content area. The science fair project of two junior scientists in Nigeria may hold the key to ending "morning breath." Through experimentation, the two teenage girls determined that African walnuts were able to kill bacteria that cause bad breath. Their project was presented at the Intel International Science and Engineering Fair.

This informational text resource is intended to support reading in the content area. The article outlines the scientific mindset that led William Herschel to arrive at the discovery of infrared light, an unexpected consequence of an experiment he was conducting. More generally, the article demonstrates the scientific process, from hypothesis to observation and from inference to conclusion.

This fun worksheet uses the popular Sponge Bob characters to help students learn characteristics of the process of science inquiry, specifically, the identification of variables. Other concepts and skills that are addressed include: developing a conclusion, the purpose of a control group, the placebo effect, the initial observation, and analyzing data charts.
