Learners read a variety of letters from soliders who were on the front lines during World War II. After viewing an excerpt from "The War", they answer discussion and comprehension questions based on the letters and video. To end the...

Young scholars explore two-dimensional and solid shapes. In this shapes and patterns geometry lesson, students work with a partner to create identifiable objects using tangrams. Young scholars describe the attributes of their shape and...

Challenge mathematicians to examine and sort a variety of 2-D and 3-D figures with a 10-problem solid shapes worksheet.

Tall and skinny or short and stout, which glass hold the most liquid? Learners analyze dimensions of cylindrical glasses to determine the one holding the greatest amount of liquid. They brainstorm the relevant dimensions before making...

In this math worksheet, students cut out six three-dimensional shapes. The shapes include a sphere, cone, cylinder, pyramid, and cube.

Sixth graders examine the role of packaging of everyday products and urge manufacturers to reduce the amount of it. They also discover how many products they use everyday can be recycled.

In this states of matter worksheet, students learn about the 3 different states of matter and how matter shifts states. They then answer the 20 questions in the packet. The answers are on the last page.

Students observe the diffusion of air molecules through a balloon. For this chemistry and molecules lesson, students fill balloons with air and a scented substance and observe whether the scented air is able to permeate the balloon.

In this scientific models worksheet, students will use a model to represent matter in its various states. Students can use a computer graphics program, drawing on paper, or three-dimensional creation. Then students will complete 3 short...

Students identify the various states of water. They use hypothesizing and hands-on experimenting on changing the states of water, the properties of water, and the role of heating and cooling in the changes of state.

Learners explore the different phases of a crystal.  For this mineral lesson students grow their own sugar crystals using a sugar recipe. 

Students describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...

Young scholars observe crystals and their shapes and formation. In this crystal formation lesson, the teacher prepares crystal gardens for the students to observe, then the class finds examples of crystals in nature and observe a teacher...

Students examine how a hot air balloon works. In this hot air balloon lesson, students do an experiment to test the effects of heat on density. Students make their own hot air balloon and act out how nitrogen moves when turned to a liquid.

Students discuss a given set of questions based on Chemistry and matter and review a glossary of terms. They conduct experiments on each state of matter: "Dry ice and water, Dry ice and soap and Dry ice and Isopropyl Alcohol." and...

In this thermochemistry instructional activity, learners indicate whether the given processes are endothermic or exothermic reactions. Students complete the phase change diagram as well as define a given set of vocabulary words. Learners...

Young scholars investigate common household items and classify them into types of matter. In this matter lesson, students group given items into categories based on their characteristics. They also complete a concept map about matter and...

Students explore the benefits of recycling paper. In this recycling activity, students use statistics to calculate the amount of paper that is thrown away each week and construct a graph. Students analyze the data and calculate the...
