In this physics interactive lecture demonstration, students will observe the constancy of gravity in a variety of different situations. They will predict what will happen if a plastic bottle, filled with water and having a hole near the bottom, is dropped. Will the bottle fall at the same rate as the water inside the bottle?
Students will: determine the number of valence electrons using energy level diagrams; …
Students will: determine the number of valence electrons using energy level diagrams; explain why elements lose or gain electrons during ionic bonding; define an ion; write correct ion notation; describe some properties of ionic compounds; develop a hypothesis which explains what happens when an ionic compound dissolves.
This activity guides students through the process of determining how ionic and …
This activity guides students through the process of determining how ionic and binary compounds as well as inorganic compounds are named. Students compare various compounds and determine what rules are most appropriate for naming each compound. In addition, the activity helps familiarize students with polyatomic ions and how oxyanions are named.
In this lab activity, students will determine the effect of the angle …
In this lab activity, students will determine the effect of the angle of incline upon the force needed and upon the work done when pulling a cart up an incline to the same height at a constant speed. Students will record and graph data and write a comprehensive report summarizing the lab.
In this lab students will conduct an investigation to find out if …
In this lab students will conduct an investigation to find out if substance either lose or gain mass after a chemical reaction takes place. Students will combine (and measure the mass of) 200 ml of water with a measured mass of antacid. They will add these two masses together BEFORE combining them. Students will then combine the two substances together in a capped bottle and record observations. Students will wait for the reaction to finish, then measure mass of the system. Students will then answer lab questions, and balance the chemical equation for this reaction.

This inquiry-based activity reinforces the idea that a mixture can be taken apart by physical means. Students will have 3 hours to separate as much pure substance as they can. These will be broken into percentages based on purity and the amount they have been able to separate. There is no set procedure for this open, inquiry-based activity; students will record the procedure they use as they complete the activity.
This resource will help students understand the chemistry and gain insight into …
This resource will help students understand the chemistry and gain insight into the history featured in the development of baking powder. It includes a reading resource, a mapping activity, and a flow chart activity. Student identify chemical substances, name common ions and molecules, write balanced formulas, and interpret the chemical reaction in baking powder.
This resource supports English language development for English Language Learners. Students will …
This resource supports English language development for English Language Learners. Students will study various aspects of atomic theory and elements and incorporate language objectives in this SIOP unit. The resource includes targeted vocabulary, student worksheets, and activities across all language domains.
Through this lesson, students will gain a solid understanding of the three …
Through this lesson, students will gain a solid understanding of the three types of heat transfer: radiation, convection and conduction, which are explained in detail and related to the real world. They learn about the many ways solar energy is used as a renewable energy source to reduce the emission of greenhouse gasses and operating costs. Students also explore ways in which a device can capitalize on the methods of heat transfer to produce a beneficial result. They are given the tools to calculate the heat transferred between a system and its surroundings.

In this lesson students will study how propellers and jet turbines generate thrust. This lesson focuses on Isaac Newton's 3rd Law of Motion, which states that for every action there is an equal and opposite reaction.
In this lesson students learn about bond strengths/bond types by observing a …
In this lesson students learn about bond strengths/bond types by observing a demonstration. They apply this knowledge in their own experiments so they can predict bond strengths /bond types based on the locations of the bonding atoms on the periodic table. Students will illustrate the type of bond formed between atoms using 3-D models made from foam balls, toothpicks, rubber bands, and pipe cleaners.
In this activity, students (and staff) wear nametags containing the name of …
In this activity, students (and staff) wear nametags containing the name of a cation or anion. Students must meet students and/or staff "ions" and create ionic compounds. Students gain practice balancing ionic formulas and naming ionic compounds. Students should "bond" with students/staff outside their classroom. Naming handout and flowchart also included.
