Middle schoolers are introduced to the concept of buoyancy. The Video used in this lesson demonstrates and explains the characteristics of objects that sink and float. It presents the concepts of displacement, weight, and buoyancy.

Students investigate the effect of weight on normal friction or the friction due to surface roughness. They tell about the effects of contact area that occurs as a result of molecular attraction by looking at data on line graphs.

In this transpiration activity, students will conduct an experiment to measure the rate of transpiration from a plant by measuring how much weight the plant loses over 5 days. Students will record their data and create a graph of the...

Students observe falling objects. In this lesson about gravity, students work in groups to determine how objects fall. Students determine speed of objects falling and whether weight is a factor. Students understand the concept of gravity.

Learners analyze the correct use of technology as it relates to math and science. In this science lesson, students investigate force and weight as it relates to building an object. They build a bridge and draw conclusion based on the...

Students engage in a lesson that reinforces rockets as a vehicle that helps us explore outside the Earth's atmosphere by using the principles of Newton's third law of motion. Also, the principles that engineers deal with when building a...

Students use an appropriate unit of measure to measure an item in the classroom. They create a PowerPoint to demonstrate the measurement process. Pupils are divided into pairs. Students use a concept map to discuss the terms for...

Students play a role of a registered dietician to examine low carbohydrate diets and diets currently on the market and compare them to a balanced diet. They determine a strategy for weight loss for a patient that meets specifications...

Students experiment with objects of different densities. For this density lesson, students examine same-sized objects with different weights, then look at a teacher explanation of density. Students make wave bottles and a density jar...

In this exploring pendulums worksheet, students experiment with pendulums they make in the lab. They vary the length of the strings and the weights to observe the changes in the pendulum's amplitude and frequency. They answer 3 analysis...

For this universal gravitation worksheet, middle schoolers fill in the blanks to complete sentences with 11 given terms about gravity, inertia, acceleration, mass and force. Students also answer 7 questions about mass, weight and force.

Students discover the actual size and weight of many insects and animals. In this biology lesson, students investigate animals and insects to determine their actual weight and size. In groups, students create an animal or insect of their...

Learners recognize the effect of Earth's gravity on an object's weight. In this force and motion instructional activity students understand the role of gravity when you drop an object. Learners experiment with small items. Students...

Students investigate technology and its purpose in the workplace. In this geometry lesson, students design and build a paper towel structure to investigate motion and forces. They are given a restricted weight and asked to build their...

In this experimental design and measurement worksheet, students answer questions about independent and dependent variables, they write hypotheses, they identify instruments that measure mass, weight, and volume and they calculate the...

Tenth graders plan a diet for a variety of needs. They create an appropriate menu and exercise program to maintain a healthy weight.

Students design a simple boat and predict how much weight it can carry. They should also discover why objects float or sink and how this can be determined experimentally. A great lesson on buoyancy!

Students build an arch with no mortar following the design of the Romans. They use cookies to represent the blocks used and work to distribute the weight on the stones.

Learners conduct the Biuret Test and the Bio Rad Protein Assay. They examine the spectrophotometer and graph molecular weights and the concentrations of the proteins investigated. They prepare solutions for the Bio-Rad test and use the...

Students learn along with Ms. Frizzle's class. In this Magic School Bus lesson plan, students explore craters that objects of different sizes and weights (marbles, Ping-Pong balls, and aluminum foil balls) create.

Students explore the period of a pendulum. In this pendulum lesson plan, students make a pendulum using a fishing weight, hook, string and paper clip and measure the pendulum's period. Students measure the number of seconds for 10 cycles...

Middle schoolers investigate the relationship between pressure and volume in gases. In this gases, pressure and volume lesson plan, students learn about the meaning of pressure. They observe different nail boards and are able to sit on...

Although this is a science lesson, it can be adapted to help meet Common Core standards in math as well. Starting scientists describe physical properties of objects and explore three forms of water. To address the Common Core, they can...

First graders locate and identify solids in the schoolyard. In this geometric solids lesson, 1st graders locate two solids on the playground. They work as a group to compare and contrast them according to shape, texture, weight, size,...
