Part of NCSSM CORE collection: This video shows the collection of data to determine the rate law for the reaction of bromate and iodide ions in acidic solution.

Part of NCSSM CORE collection: This is the document for the bromate iodide rate law lab.

Part of NCSSM CORE collection: This is the document for a buffer activity lab. Students will measure and record the pH of various solutions and then measure the pH of the solution after the addition of a buffer solution. They will use their results to gauge the effectiveness of the buffers. NOTE: This lab uses CBL probes and TI-83+ calculators.

This article provides instructions for students to build a radio telescope and offers several possibilities for using them to study space.

In this activity, students learn about how life on Earth is possible and what would be needed to live in other locations in the solar system.

The teaching activities in this article aim to actively involve students in a search for mutations that could potentially lead to cancer development, using real genomic data.

In this lesson, student teams compete to construct the fastest car, using their knowledge of physics.

Students are introduced to the topic of bioremediation and collect information about Azolla, such as the morphology of water plants as opposed to land plants, the importance of symbiosis, the nitrogen cycle, the use of Azolla in agriculture, and Azolla’s ability to absorb heavy metals. Students formulate the research questions and hypotheses that they would like to investigate. Possible topics include measuring the gain in biomass depending on growth conditions (e.g. CO2 level, iron level in the water, amount of light), or the effect of Azolla on water quality.

In this activity, students use a vivid colour-changing demonstration to illustrate a chain of redox reactions, whereby electrons are transferred between different compounds and ions.

Students are asked to crack a code of different sequences of letters using the messages that those sequences encode. In each of the first three steps, each team is given a different set of letter sequences and corresponding messages. At each step, they will need to re-evaluate their conclusions from the previous steps, and modify their solution to the code. All groups will be working to crack the same code, using different examples. Students should focus on finding patterns and relationships. The crux of the activity is the existence of the code rather than the details of transcription and translation, which can be addressed in subsequent lessons.

In this activity, students will build a model in order to demonstrate how and why eclipses happen.

In this game, students are introduced to the use of DNA in forensics and the ethical questions involved.

Students investigate the relationship between the presence of green pigment, food production, and leaf growth.

This article provides several simple, fun experiments for elementary students to investigate what happens to solids, liquids, and gases when they are heated.

This lesson provides several challenges that students will be able to solve by applying simple physics principles. Solutions are provided.

This article describes a new technology that will make gene editing easier and less expensive.

In this two-part lesson, students learn about soil structure and its organic matter content. In the first activity, students carry out a simple experiment to collect soil samples and test their stability to learn which types of soil are liekly to be more prone to erosion. In the second activity, students find out about the mineral composition of soil samples.

This educational activity uses everyday materials to simulate a microarray experiment in the classroom. The game simulates the different steps that researchers take in performing microarray experiments and in analysing the results. The activity can be used to complement lessons on genetics, cell development and genetic diseases.
