Students explore the effects of pollution on water supply and how to identify safe drinking water. They test different samples of water over regular intervals and analyze the results to see if they are cyclical or represent a growing...

Students are given the "Pet Store Decisions" task sheet and a rubric that goes with it. Students discuss the task and make a plan for using the rubric sheet to complete the task. Students formulate questions, studies and data collection...

Eighth graders use goldfish crackers to simulate a capture-recapture method of data collection. They fill in a chart and determine the averages. They find the estimated population of fish and the actual population of fish based on the...

Students explore sampling with and without replacement. They explore the effects on the probability of drawing a desired object. Students examine probability and the difference between sampling with and without replacement.

Students examine how to take a sample by looking at rocks in the schoolyard. For this sampling lesson, students discuss ways to classify rocks by color, size, and weight. They think about how many rocks would make a good sample of...

Pupils analyze sampling from different population. In this statistics instructional activity, students define the meaning of sample sizes and what causes an increase or decrease. They graph their data on the Ti calculator and draw...

Learners use family names to gather and analyze data. In this counting lesson, students use graph paper to help organize their data and then, in a staircase fashion, organize the names from longest to shortest so they can answer...

Students work in pairs to manufacture a product for a potential customer. They interview potential customers and collect data. Students develop a customer interview profile. They manufacture drill drift part to customer's specifications...

In this environmental studies worksheet, students create a data table to discover how much water each person uses on a daily basis and what it is used for. They complete a post activity to make and test solutions for pollution using a...

Young scientists learn the laws of genetics through data collection and research. They use discussions and online resources to develop an understanding of the related vocabulary.

Crystals are more than meets the eye! Can learners tell them apart simply by observation? As they examine five samples with a magnifier, they find that appearance alone is not enough. This serves as an introduction to a mini unit on...

The relationships within and between ecosystems can be explored. after examining an area for living and non-living things students complete the same examination in the forest ecosystem. Students identify abiotic and biotic elements in an...

The heat of solution measures how much thermal energy a dissolving substance consumes or gives off. The experiment demonstrates both endothermic and exothermic reactions. Scholars dissolve several substances, measure the temperature...

Students explore a variety of guidelines that involve collecting plants in a responsible manner and participate in a plant pressing activity. In this teacher's plant collection guide lesson, students collect data regarding plants,...

Students practice formulating a hypothesis and designing an experiment to test the hypothesis. They identify several sampling techniques they can use to test their hypotheses.

Young scholars explore the concept of sampling techniques. In this sampling techniques lesson, students identify possible sources of bias in situations such as phone polls, supermarket surveys, and drawing names from a phone book. Young...

Students study four samples of "rain water". They asked to determine the pH of the samples and then to neutralize them. Students are asked to predict any negative effects which might be associated with water having a low pH and to...

In this math learning exercise, learners take the time to count out the colors of the candies. They graph the results and make inferences from the information.

Students complete activities using a frequency table and construct a pie graph for the data. In this frequency table activity, students complete a survey to find data for a frequency table. Students use the given link to make a pie graph...

Take a chance on an informative resource. Scholars conduct probability experiments involving coins and number cubes to generate data. Compiling class data helps connect experimental probability to theoretical probability.

Pick and choose which activities to include in this crime scene investigation. Junior detectives can examine fingerprints, DNA, blood samples, or bone structure.  The plan suggests you have teams solve a mystery, but it does not...

Hard boiled or raw? Which egg will you get? A hands-on activity has scholars explore the impact of conditional probability. Based on a skit from the Tonight Show, pupils model the selection of the two types of eggs using beads. They...

Healthy invertebrates mean healthy ponds. An outdoor activity has scholars collect samples of invertebrates from local lakes or ponds. They identify and count different species and use the information to estimate the level of pollution...

Ice core samples give scientists access to climates of old—those from more than 800,000 years ago. Through an analysis of various temperature graphs from ice cores, tree rings, and weather stations, scholars compare historical climates...
