Curated OER
Will Biotech Crops Solve World Problems?
Young scholars read an online article to examine what biotechnology and agricultural biotechnology are. They answer questions and complete worksheets based on the article's information.
Curated OER
Click, Clack, Moo: Electric Blanket Science
Young scholars read Click, Clack, Moo: Cows That Type by Doreen Cronin and discuss the similarities and differences between electric blankets and regular blankets. They brainstorm a list of reasons why the farm animals wanted electric...
Curated OER
Cell Swelling and Shrinking
Students examine the concept of osmosis in relation to dehydration. They identify the function and structure of semi-permable membranes. They predict how certain processes can affect the characteristics of an organism.
Curated OER
Using a Thermometer
First graders use their senses to formulate questions and make predictions to determine what is in the "Wonder Bag". They hold pieces of ice and examine while listing descriptors on a chart and then take their own temperature using an...
Curated OER
Friction Restriction: Creating a Design Plan to Redesign the Tread of Tennis Sneakers to Increase Friction
Young scholars evaluate the friction of tennis sneakers and redesign them to increase friction. For this physics lesson, students calculate starting, sideways and forward stopping friction. Using quantitative data, they prove that...
Curated OER
Chihauhan Desert Journaling Activity
Learners explore U.S. geography by completing an observational activity with classmates. In this New Mexico lesson, students research the Chihuahuan Desert by visiting several Internet sites. Learners write the data they've collected in...
Curated OER
Swingers
Students investigate the motion of a swinging pendulum. They experiment with a pendulum to find out why it might swing at different speeds at different times.
Curated OER
Magnifiers
Students describe how several different objects magnify a provided sentence and decide if they are good magnifiers or not. They then write a sentence describing two properties an object must have in order to be a good magnifier.
Curated OER
Interdisciplinary Task: Weather
Students design a chart to use to record the weather for five days. They then build an anemometer to record wind speed and discover why they are used for this purpose.
Curated OER
Rolling Down Hill
Students perform an experiment, collect, and analyze data of a rolling marble down a ramp. They report results after they complete their experiment. Students are assessed in science and writing.
Curated OER
Temperature and Enzymes
Students compare the times it takes the milk in each of two cups to curdle. They are told that an enzyme that is added to the milk, rennin, is involved in the natural curdling process of milk. Students are asked to consider what...
Curated OER
Soap, Wood, and Water
Students measure the properties of two different types of soap and wood and calculate their densities. Then they predict whether or not whether or not each object would float or sink in fresh or salt water.
Curated OER
Living and Nonliving Things
First graders distinguish between living and nonliving objects, and compare living organisms and nonliving objects.
Curated OER
Types of Matter
Students analyze different types of matter according to its general and specific properties. They design an experiment to classify matter. Students are shown cornflakes and raisins. They are asked what type of substance is each...
Curated OER
Color My World
Students identify colors created by mixing primary colors and describe the process. They then design a book using the colors of a given season entitled "Colors of the Season".
Curated OER
Water and Ice
Pupils explore the states of matter. In this physical science instructional activity, students observe what happens to water when it freezes and record observations. Pupils then observe ice when it melts and record observations.
Curated OER
Floating Pencil
Students discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample is...
Curated OER
Rising Waters
Fourth graders rank balls by size from smallest to largest and from lightest to heaviest and then by how much they made the water rise. They then discuss why certain balls make the water rise higher than do other balls.
Curated OER
Colored Dots 1
Students observe that colored markers are a mixture of many different colors by performing a chromatography experiment. They make observations, record information, and make generalized inferences from their observations.
Curated OER
Whose Parts Do I Have? (Wings and Things)
Learners identify an animal and a body part and then matches a body part to a specific animal. This will assess their ability to sort organisms and objects into groups according to their parts and describe how the groups are formed and...
Curated OER
Changing Ramp Heights
Students conduct an experiment to determine how the change in ramp height affects the distances a ball is able to move a stationary cup. Data is collected from several trials and recorded and analyzed.
Curated OER
Starch and Sugar Testing 1
Eighth graders determine the presence of starch and sugar in unknown solutions. This task assesses students' abilities to observe, record and interpret data, classify, generalize/infer, construct data tables, and identify sugar and...
Curated OER
Powder
Learners investigate several unidentified substances and suggest a use of each substance. They can explain that a substance has characteristic properties, such as density, a boiling point, and solubility, all of which are independent of...
Curated OER
Crustal Sinking
Students measure the rate of sinking of a test tube into a beaker of "glop", representing a model of the interaction between the Earth's crust and upper mantle. This task assesses students' abilities to make simple observations,...
