Heat and Matter
Students explore liquids and solids by conducting in class experiments. In this matter lesson, students define the properties of matter and how heat can change those properties. Students experiment with heating objects such as butter and...
Curated OER
Mixtures of Matter
Students experiment with mixtures of matter. In this matter lesson, students investigate which liquids form a solution when mixed together and which do not. Students also identify which solids can be separated from matter.
Curated OER
Mixtures of Matter
Students experiment with solids and liquids. In this mixtures of matter instructional activity, students combine matter to form solutions. Students hypothesize, test, and analyze the data to draw conclusions. The instructional activity...
Curated OER
Periodic Table
Students identify the periodic table trends and predict material properties. They also design and conduct simple experiments and test material properties. Finally, students compare and contrast material properties and that chemical...
Curated OER
Causal Patterns in Density Phenomena
Learners consider the causes of density at a microscopic level. They then discover that one cause of density has to do with how many protons and neutrons the material contains.
Curated OER
Chemicals, Chemicals, Everywhere
Students divide substances into categories: made of chemicals/not made of chemicals, synthetic/naturally occurring, and toxic/nontoxic. They observe a mystery chemical and determine what precautions they need to take when handling an...
Curated OER
The Physical Behavior of Matter
Learners distinguish between three phases of matter: solid, liquid and gas, on the molecular level. They compare and predict the relative compressibility of the three phases of matter through journal writings and drawings.
Curated OER
Dust in the Wind; Chemicals in the Water
Students explore mechanical and chemical weathering at stations. They articulate some mechanisms of chemical and mechanical weathering through exploration in a lab. Students stations describe how chemical weathering differs from...
Curated OER
Heat Discrepancies
Students answer the question, "Why do Eskimos build houses out of ice to keep warm. Since heat goes from hot to cold, don¿¿¿t the ice walls take away the warmth inside the house?" They explain how snow or ice can actually be insulators.
Curated OER
Plant an Ozone Monitoring Garden
Students create a garden. In this ozone lesson, students discuss ozone injury, identify plants sensitive to ozone, and then plant their own ozone garden.
Curated OER
The Influence of Carbon Dioxide on the Chemistry of Soda
Students investigate the carbon dioxide content of different sodas. In this chemistry lesson, students explain why PET containers are preferable than HDPE for soda bottles. They collect data and graph them.
Curated OER
Crystal Growing
Students explore the different phases of a crystal. In this mineral lesson students grow their own sugar crystals using a sugar recipe.
Curated OER
What Changes Occur When Ice Melts?
Young scholars explore the physical process of melting. They observe melting ice and answer questions related to energy transfer during phase changes.
Curated OER
Lesson- Colors of Stars
Student describes what happens to the color of a stove burner or a coal as it gets hotter. They use the applet to determine what range of temperatures range give you a red light, what range of temperatures would give you a white light,...
Curated OER
Learning Lesson: Heavy Air
Students complete an experiment in which they discover air has weight. They use the same size balloons to explain this concept. They also examine thunderstorm safety.
Curated OER
Electrons
Students discover that there are many facets to the electron in chemistry such as electron cloud. They view movies an animations of electrons. Students visit links pertaining to electrons.
Curated OER
Science: What Happens to Create the Lode?
Young scholars understand how mineral deposits are formed and why they are not evenly dispersed. They create and describe three different precipitates from four solutions simulating mineral ore deposit formation in sedimentary rock.
Curated OER
Energy Dispersive Spectroscopy
Students calculate the values of electron binding energies. In this physics lesson, students solve for different wavelength characteristics of X-rays. They present their findings to the class.
Curated OER
Grating Spectrometer
Students calculate the Balmer series. In this physics lesson, students observe hydrogen lamp spectra using spectrometers. They calculate wavelength and compare them with their theoretical calculations.
Curated OER
Ammonium Nitrate - Heat of Solution
Young scholars quantify the relationship between temperature, energy and heat
and define an endothermic reaction. They measure the energy change caused by dissolving one mole of ammonium nitrate in water.
Curated OER
Where's the Evidence?
Eighth graders observe evidence of chemical reactions. In this chemical reactions instructional activity students study chemical processes and complete a lab activity.
Curated OER
Physical and Chemical Properties of Water
Students experiment with water as a component of suspensions, solutions, and heat conduction contributing to the use of food and the health and wellness of human beings.
